Class SecureLinkTool

java.lang.Object
  org.apache.velocity.tools.view.tools.LinkTool
      org.apache.velocity.tools.struts.SecureLinkTool

All Implemented Interfaces:

java.lang.Cloneable

public class SecureLinkTool
extends LinkTool

Tool to be able to use Struts SSL Extensions with Velocity.

It has the same interface as StrutsLinkTool and can function as a substitute if Struts 1.x and SSL Ext are installed.

Usage:

 Template example:
 <!-- Use just like a regular StrutsLinkTool -->
 $link.action.nameOfAction
 $link.action.nameOfForward

 If the action or forward is marked as secure, or not,
 in your struts-config then the link will be rendered
 with https or http accordingly.

 Toolbox configuration:
 <tool>
   <key>link</key>
   <scope>request</scope>
   <class>org.apache.velocity.tools.struts.SecureLinkTool</class>
 </tool>
 

Since:

public SecureLinkTool()

Method Detail

setAction

public SecureLinkTool setAction(java.lang.String action)

Returns a copy of the link with the given action name converted into a server-relative URI reference. This method does not check if the specified action really is defined. This method will overwrite any previous URI reference settings but will copy the query string.

Parameters:

action - an action path as defined in struts-config.xml

Returns:

a new instance of StrutsLinkTool

setForward

public SecureLinkTool setForward(java.lang.String forward)

Returns a copy of the link with the given global forward name converted into a server-relative URI reference. If the parameter does not map to an existing global forward name, null is returned. This method will overwrite any previous URI reference settings but will copy the query string.

Parameters:

forward - a global forward name as defined in struts-config.xml

Returns:

a new instance of StrutsLinkTool

computeURL

public java.lang.String computeURL(javax.servlet.http.HttpServletRequest request,
                                   javax.servlet.ServletContext app,
                                   java.lang.String link)

Compute a hyperlink URL based on the specified action link. The returned URL will have already been passed to response.encodeURL() for adding a session identifier.

Parameters:

request - the current request.

app - the current ServletContext.

link - the action that is to be converted to a hyperlink URL

Returns:

the computed hyperlink URL

getActionConfig

private static org.apache.struts.config.SecureActionConfig getActionConfig(javax.servlet.http.HttpServletRequest request,
                                                                           javax.servlet.ServletContext app,
