About Sites

The Sites feature enables designers and web developers to build and deploy public web sites and web-based applications using the LongJump Platform. These Dynamic Sites leverage the backend data and content that reside within a user account. Dynamic Sites eliminate the need for a specific web server or database and instead leverage the robust administration and presentation capabilities of the LongJump Platform, as well as its relational database.

Dynamic Sites are defined by Java Server Pages (JSPs) and any included static resource files (images, CSS, etc.). The web pages can be accessed by both authenticated (registered) and unauthenticated (anonymous) users. They can be customized using both CSS and jQuery widgets. (You can can also upload other JavaScript libraries as static resources, and use them in your pages.)

In addition to Pages, a developer can use Classes/Controllers to write business logic, adhering to the industry standard MVC architecture, where Pages handle the View, Classes and Controllers handle the Controller level, both of which interact with data stored on the platform (the Model) using the platform's Java API and REST API.

Sites are accessed using URLs that point to pages, controllers, and Action Tags.

Using Sites

Dynamic Sites can be used to build many kinds of web sites:

Portal web sites
Run your entire public corporate web site on LongJump Platform Dynamic Sites, or create intranet sites by IP restricting the sites. In addition, Dynamic Sites enable you to create authenticated and unauthenticated pages and data to be served directly to your audience, making it ideal for portals.
Interactive business applications
Use LongJump Platform Dynamic Sites to create interactive web applications where users can interact with complex business processes. For example, you may create a job posting and resume submission application or create an application for mobile updates to LongJump Platform data.
Community and social networking
LongJump Platform Dynamic Sites can be used to design websites that engage a community of users to submit and vote on ideas, exchange information, or securely collaborate on projects.

Login Options

Users can always create a new username and password. But by including the appropriate tags, the site can also allow users to login:

  • Using a Facebook ID ([[]])
  • Using a Google ID ([[]])
  • Using their Gmail account ([[]])


Terms Used in Sites

Site User

  • A Site User is any user that registers with the site.
  • When a Site User registers, a User record is created for them, so they are guaranteed to have a unique identity in the platform instance.
  • That identity can be used to store profile information.
  • Operations they perform are undertaken with that identify. (The operations that can be performed are determined by the Role associated with Site Users.)
  • However, that identity does not have the ability to log into the platform.
  • A Site User therefore does not count as a "platform user", from the standpoint of tenant billing. (From that standpoint, only platform users count. So if you have 5 people in your organization, and 100,000 Site Users, your tenancy is considered to have only 5 billable "users".)

Anonymous Site User

  • Someone can use the site without registering, as well.
  • In that case, they perform operations using the default identity configured for the site.
  • The Role associated with the default identity determines which operations can be performed without registering.

Base URL

  • The Base URL is the default web address of the site that displays the home page (landing page)
  • Includes the {domain} as part of the URL, for example: mydomain.com
  • Learn more: Building Site URLs

Add or Edit a Site

  1. Designer > Sites
  2. Click [New Site], or
    Select a Site and click [Edit]
  3. Fill in the Site properties.

Site Properties

Site Information

Name
Site name
A unique site name within a tenant. This name is part of the Base URL/Default Web Address.
Default Web Address
Read Only
Created from the Site Name. This is the default unsecured URL generated for this site.
https://na.longjump.com/networking/sites/123456/mysite
Default Secure Web Address
Read Only
Created from the Site Name. This is the default secured URL generated for this site.
https://na.longjump.com/networking/sites/123456/mysite
User Web Address
Vanity URL
A "pretty" URL, used as a redirect from the Default URL. Site developer can add a CNAME entry, which will redirect www.mysite.com to the platform. (The platform's Site tags rewrite URLs in a page to point to this User Web Address.)
Is Site Active
Checkbox, checked by default
  • If checked, this site is active. A single click interface to activate/deactivate a site.
Start Page
A predefined Page that appears as the landing page when the site is launched.
Inactive Page
A predefined Page that is displayed if the Active checkbox is unchecked. This page can be used as an Under Construction/Maintenance page.
Error Page
The default page to display when an error occurs.
File Not Found Page
The page to display when a 404 - File Not Found error occurs.
Site Template Page
A predefined JSP page that will act as a Site Template.
Considerations
  • Only JSP pages for which Include header files is disabled are shown. (JSP pages that include header files will not work, as the header files include libraries that are incompatible with site operations.)
  • For sophisticated sites that use a library like jQuery to nest pages, the Site Template feature won't be of much value. In such circumstances the Site Template will be applied to the main page, as desired, but it will also be applied to subsidiary pages as they are loaded into subsections of the main page--behavior which is generally undesirable.

Access Type

Login As User for Unauthenticated Access
Use the lookup Lookupicon.gif icon to select a User. If a page does not need authentication, and if a Site User is not logged in, Platform will log in the selected User for doing any operations on the server.
Register Site Users with this Role
Use the lookup Lookupicon.gif icon to select a Role. Newly registered users will take the selected Role.
Register Site Users with this Team
Use the lookup Lookupicon.gif icon to select a Team. Newly registered users will belong to the selected Team.
Login Page
Any unauthenticated access of a page which requires authentication, will be redirected to this page. Typically this page will have the login box.

Manage Pages

List of Pages Available to the Site
Pages available to the Site
A list of pages available to the site
Authentication Required?
Checkbox, unchecked by default
  • If checked, this page requires authentication. Unauthenticated access of this page will redirect user to the page denoted by Login Page property.
Delete
Optionally, click the trashcan Trashcanicon.gif icon to remove the page from the site. The page is only removed from use in the site, and is still present in the Pages repository.

Building Site URLs

One of the most important features of Site functionality is the way URLs are handled in a Site page.

  • After you configure the URL forwarding (redirect) from your web address to the Site's Default Web URL/Base URL, the Platform is ready to serve your site
  • In any typical web application, URLs include the site {domain}
  • In the case of Sites, the user will have to write absolute URLs pointing the User's web address, since the content is being served from Platform's server
  • URLs can be hard-coded with the Site URL or the Platform URL JSP tags can be used
Learn more: Tags

Sites are built using a combination of Pages, Classes, Controllers.

Learn more: Working with Pages and Classes

URL Types

URL types supported in Sites include Pages, Controllers and Actions.

Pages Example

For this Base URL and User Vanity Web Address:

Base URL (Default Web Address)
https://na.longjump.com/networking/sites/1234567/mysite,
where mysite is derived from the User Vanity Web Address, http://www.mysite.com
Page URL
Base URL + /pages/{page}
Page Name
home.jsp
URL displayed in the page
http://www.mysite.com/pages/home.jsp
URL forwarded to the Platform Server
https://na.longjump.com/networking/sites/1234567/mysite/pages/home.jsp

Controller Example

For this Base URL and User Vanity Web Address:

Base URL (Default Web Address)
https://na.longjump.com/networking/sites/1234567/mysite,
where mysite is derived from the User Vanity Web Address, http://www.mysite.com
Controller URL
Base URL + /controller/{controller_path}
Controller Path
com/platform/demo/samples/JobsController
URL forwarded to the Platform Server
https://na.longjump.com/networking/sites/1234567/mysite/controller/com/platform/demo/samples/JobsController

Action Example

For this Base URL and User Vanity Web Address:

Base URL (Default Web Address)
https://na.longjump.com/networking/sites/1234567/mysite,
where mysite is derived from the User Vanity Web Address, http://www.mysite.com
Action URL

Standard Action
login
URL displayed in the page
http://www.mysite.com/login
URL forwarded to the Platform Server
https://na.longjump.com/networking/sites/1234567/mysite/login

Using Controllers and Pages

Used to customize the business logic for the Site. In this case, all the responsibility of the data model, business logic and display part is written by the user.


URI Base URL + "/controller/{controller}"
Base URL + "/pages/{page}"
Examples: https://na.longjump.com/networking/sites/123456/{site}/controller/JobsController
https://na.longjump.com/networking/sites/123456/{site}/pages/MyPage.jsp
Parameters
{parameter_name}
Any parameter needed for any controller/page written by the user. Please refer to the Classes/Pages documentation on how to write controller/pages.

Included Server-Side Actions

The LongJump Platform includes a number of built-in server-side actions. These actions are typically useful for an authenticated site. Common actions for a typical Web Application which supports authentication are listed here, and are used with the Common Parameters.

Considerations
  • Each action is available as a service through a URL and expects certain parameters for a successful execution.
  • Both HTTP GET and HTTP POST are supported for these actions.
Action Description URL
Login to the site Login to the LongJump Platform as a Site User Base URL + "/login"
Register a New User Create a new Site User Base URL + "/register"
Change Password Change the Site User's password Base URL + "/change_password"
Update Profile Update a User Profile Base URL + "/update_profile"
Validate the Security Question Validate the security question, as part of the Forgot my Password process Base URL + "/validate_security_question"
Reset Password Reset a Site User's password Base URL + "/reset_password"
Manage Objects Add/update/delete a record in an Object Base URL + "/service"
Download File Download a Document Base URL + "/download_file"

Tag Library

To make coding of Pages easier, the LongJump Platform provides a set of custom JSP tags. Similar to JSTL (Java Standard Tag Library), these tags make development of pages easier and make a clear separation between View, business logic (Controller) and Model of a use case. Learn more: MVC (Model-View-Controller). To successfully use these tags, include a taglib directive in any Page used to build the Site.

Hidden Tag

Used to render the HTML input type hidden element

Attributes
Common Attributes for HTML Tags are available
Example
<%@taglib prefix="lj" uri="/LJTagLib"%>
<lj:hidden name="jobPost" value="${param.id}" />
Include Tag

This tag has two uses:

  • It is used in a Site Template (a wrapper page) to indicate where to include the content of the page being visited.
  • It is used to include another JSP page stored on the platform. In that case, it can help to organize your pages. For example, common libraries can be declared on a single page--say, common.jsp. If that page is included everywhere, a new library can be added to every page simply by declaring in the common page.
Attributes
Tag Type Description
file String Specifies the content to include:
  • ${_page} in a Site Template
  • pages/{pageName} in other pages, where pagename includes ".jsp"
Examples
Usage in a Site Template 
<%@taglib prefix="lj" uri="/LJTagLib"%>
<lj:include file="${_page}" />
${_page} is dynamically replaced by the content of the page that is being visited.
Usage in other pages 
<%@taglib prefix="lj" uri="/LJTagLib"%>
<lj:include file="pages/jbSearch.jsp" />
jbSearch.jsp is now included in the page.
Option Tag

Used to render the HTML option element. Should be used with the SelectTag as the parent tag.

Attributes
In addition to Common Attributes for HTML Tags, the following attributes are available:

TextField Tag

Used to render the HTML input type text element

Attributes
In addition to Common Attributes for HTML Tags, the following attributes are available:
Tag Type Description
size Integer Size of the text element. Maps to the size attribute of HTML text element
maxLength Integer maxLength of the text element. Maps to the maxLength attribute of HTML text element
Example
<%@taglib prefix="lj" uri="/LJTagLib"%>
<lj:text name="city" id="city" size="15" value="${city}"/>
File Tag

Used to render the HTML file input element. Note that the form's "encType" attribute should be "multipart/form-data" for proper handling of the file element.

Attributes
In addition to Common Attributes for HTML Tags, the following attributes are available:
Tag Type Description
accept String Maps to the accept attribute of HTML input file element.
size Integer Maps to the size attribute of HTML input file element.
Example
<%@taglib prefix="lj" uri="/LJTagLib"%>
<lj:file name="attachment" id="attachment" size="15" value="${attachment}"/>

Action Tags

These tags directly map to various platform actions specified in the Actions section. These action tags render an HTML form element.

Common Attributes for Action Tags

All the action tags have some common attributes.

Common Attributes for Action Tags
Attribute Type Description
onError String Complete or partial relative URL to execute on error of the operation
onSuccess String Complete or partial relative URL to execute on success of the operation
method String maps to the HTML form element’s method attribute
name String Name of the HTML form element which is rendered as a result of this tag
preController String Name of the class whose method is executed before the controller is executed
preControllerMethod String Method of the class identified by preController, that is executed before the controller is executed. Useful in validations or some pre actions when controller is Platform.
prefill Boolean Specifies whether the values should be prefilled for the form elements within this form. Prefill logic first looks at the HttpServletRequest.getParameter("form element"), if the value is present it will render it from there, otherwise it will take it from the value attribute of the form element. This is specifically used for error handling.

Login and Registration Tags

Login tags and Registration tags have slightly different behavior:

  • Registration tags - Allow the site user to register and login using a remote ID, like Google or Facebook. When site users are already registered, they are automatically logged in. With this option, anyone can become a site user, and the only information available to the Site are the details captured in the remote registration process (at Facebook, for example).
  • Login Tags - Allow the user to login using a remote ID, but require them to have registered with the site to do so. You can use that registration process to a) capture additional information from the user and/or, b) restrict access in some way (for example, to restrict access to an otherwise-public company payroll site).

Typically, you will choose to use either registration tags or login tags. But whichever style you choose, you will typically provide site users with multiple options so they can choose how they want to log in.

Note:
For Login tags to work, the user ID at the site must be identical to the remote user ID. One way to do that is simply to require the user to enter their ID, and trust that it will match. (Typically, it will, since a user's email address is the most common form of ID. Another, more "bulletproof" mechanism is to check to see if users are registered when they login. If they aren't, send them to the registration page with the user ID pre-filled. That mechanism is more complex, but doesn't depend on users' typing ability or memory.

Action Tag Description Syntax
Facebook Registration Tag Let a site user register and login using their Facebook ID <lj:facebookregister onError="pages/home.jsp" onSuccess="pages/ticketList.jsp?fieldList=..." />
Facebook Login Tag Let a site user login using their Facebook ID, but require site registration <lj:facebooklogin onError="pages/home.jsp" onSuccess="pages/ticketList.jsp?fieldList=..." />
Google Registration Tag Let a site user register and login using their Google ID <lj:googleregister name="googleRegisterForm" onError="pages/home.jsp" onSuccess="pages/ticketList.jsp?fieldList=..." method="POST" id="googleRegisterForm">
Google Login Tag Let a site user login using their Google ID, but require site registration <lj:googlelogin name="googleLoginForm" onError="pages/home.jsp" onSuccess="pages/ticketList.jsp?fieldList=..." method="POST" id="googleLoginForm">

Data Tags

Platform specific Data Tags. These map to the Java APIs getRecord (for getting a single record by Id) and searchRecords (for getting a collection of records for a search criteria, with paging support) calls. These tags have some common attributes that are specified below.

Common attributes for data tags

Attribute Type Description
object String id or name of the user defined object
fieldList String A comma-separated list with the names of fields to retrieve.
controller String If value is "Platform", platform will retrieve the values in a data structure. Any other value will be treated as a user written controller class.
controllerMethod String The controller method to execute. (Required when using a custom controller.)
name String Name of the HTML form element which is rendered as a result of this tag.
onError String Relative URL to execute on error of the operation.
onSuccess String Relative URL to execute on success of the operation.
prefill Boolean Specifies whether the values should be prefilled for the form elements within this form. Prefill logic first looks at the HttpServletRequest.getParameter("form element"). If the value is present it will render it from there, otherwise it will take it from the value attribute of the form element. This is specifically used for error handling.
recordVariable String PageContext variable name. The result of the execution of controller (Platform/User Written) is returned as this PageContext variable. In case of Platform controller, the result object is always an instance of Result Class from Java API.
arg1 - arg10 String 10 Custom arguments that you can pass from the JSP to the controller. Especially useful when you are handling the data retrieval part using custom Controllers.
Considerations
  • The following reserved words cannot be used as the name of the recordVariable:
applicationScope 
cookie 
header 
headerValues 
initParam
 
pageContext 
pageScope 
param 
paramValues 
request
 
requestScope 
response 
servletContext 
session
