URGENT RE: token issue in hyperlink

["Nanduri, Amarnath" <Am...@Agilquest.com>]

Hello,
 
    I have posted this before. This is extremely urgent for me. I know that
the token support exists for posting Form(s). How can i ensure that this
same token will be issued to a hyperlink so that i can validate that the
user will click on the hyperlink only once ? Any help is greatly
appreciated. Thanks a lot.

cheers,
Amar..

Subject: token issue in hyperlink



Hello All ,

     I am using the Action class saveToken() method to ensure that a token
is created and set (so that the user has proper screen flow). My question is
... how can i add this token to a hyperlink ? 

 I have a hyperlink in a jsp page, which takes me to a different Action
class. I am checking for this token in the second Action class. Any help is
greatly appreciated. Thanks.

cheers,
Amar..

Here is what I do in a similar situation:

<html:link paramId="role" paramName="role"
   page='<%="/user/saveUser.do?action=Remove&org.apache.struts.taglib.html.TOKEN=" 
+
                session.getAttribute("org.apache.struts.action.TOKEN")%>'>
  Remove&nbsp;Role  </html:link>

It's ugly, but it works for now.  Notice the single quotes around the page 
argument.  Very important or the JSP parser will get confused by the 
embedded double quotes in the expression.

I've submitted an enhancement request (Bug #874 
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=874) to add an optional 
parameter to the html:link tag that would do this magic without the need 
for the expression shown above.  If I can get Struts set up to build 
locally, I will probably give implementing this a go myself so I can submit 
a patch rather than just a request.  Using the link above, you can vote for 
the implementation of this enhancement.
