public class WACheckSessionExpiration
extends CheckSessionExpiration

A subclass of the CheckSessionExpiration servlet that is aware of web applications and context root issues. Rather than specifying the absolute URL to test for expired sessions and the absolute URL to redirect to when an expired session is detected, this subclass lets you specify URL's relative to the web application's context root and converts these to absolute URL's at runtime. It can therefore detect expired sessions for a web application no matter where that web application is deployed.

To use this servlet you must specify the following properties:

insertAfterServlet

Specifies where in the servlet pipeline to insert this servlet.

webAppRegistry

Specifies the Dynamo web application registry where the web app is registered.

webApplicationName

Specifies the name by which this web application is known to the registry

relativeExpirationPath

Specifies the root path of URL's that should check for session expiration, relative to the web app context root

relativeExpirationURL

Specifies the URL to redirect to if an expired session is seen, relative to the web app context root

Constructor Detail

WACheckSessionExpiration

public WACheckSessionExpiration()

Method Detail

setWebAppRegistry

public void setWebAppRegistry(WebAppRegistry pWebAppRegistry)

Specify the Dynamo Web Application Registry that knows about the web application whose URL's we are checking for session expiration.

getWebAppRegistry

public WebAppRegistry getWebAppRegistry()

Return the Dynamo Web Application Registry that knows about the web application whose URL's we are checking for session expiration.

setWebApplicationName

public void setWebApplicationName(java.lang.String pWebApplicationName)

Specify the name by this web applicaiton is known to the web application registry.

getWebApplicationName

public java.lang.String getWebApplicationName()

Return the name by this web applicaiton is known to the web application registry.

setRelativeExpirationPath

public void setRelativeExpirationPath(java.lang.String pRelativeExpirationPath)

Specify the root, relative to the web application's context path, of the URL's that should be checked for session expiration. This value is used to set the sessionExpirationPath property in the base class by prepending the web app's context root to the value of relativeExpirationPath.

getRelativeExpirationPath

public java.lang.String getRelativeExpirationPath()

Return the root, relative to the web application's context path, of the URL's that should be checked for session expiration.

setRelativeExpirationURL

public void setRelativeExpirationURL(java.lang.String pRelativeExpirationURL)

Specify the URL, relative to the web application's context path, that we should redirect to if an expired session is seen. This value is used to set the expirationURL property in the base class by prepending the web app's context root to the value of relativeExpirationURL.

getRelativeExpirationURL

public java.lang.String getRelativeExpirationURL()

Return the URL, relative to the web application's context path, that we should redirect to if an expired session is seen.

service

public void service(DynamoHttpServletRequest pRequest,
                    DynamoHttpServletResponse pResponse)
             throws java.io.IOException,
                    javax.servlet.ServletException

Examine the current request to see if the URL matches the criteria for detecting expired sessions and if the session has actually expired, and redirect to a specified URL if necessary.

This method simply converts the relative expiration path and expiration URL properties to absolute URL's (if necessary) and then calls the superclass service method to detect and handle expired sessions.

Overrides:

service in class CheckSessionExpiration

Throws:

java.io.IOException - if an error occurred while reading or writing the servlet request

javax.servlet.ServletException - if an error occurred while processing the servlet request

constructPaths

protected void constructPaths()
                       throws javax.servlet.ServletException

Convert relativeExpirationPath and relativeExpirationURL to absolute values, taking into account the Web application's context root, and call the superclass methods to set the corresponding superclass properties.

Throws:

javax.servlet.ServletException

errorMsg

protected java.lang.String errorMsg(java.lang.String pResourceKey)

Get a formatted error message string based on an error message resource key.

errorMsg

protected java.lang.String errorMsg(java.lang.String pResourceKey,
                                    java.lang.Object pArg)

Get a formatted error message string based on an error message resource key and a single message argument.

errorMsg

protected java.lang.String errorMsg(java.lang.String pResourceKey,
                                    java.lang.Object[] pArgs)
