Everything looks fine,
this script gets called ,



when your JSP page saw this ,




I'm worried about those double quotes , remove them !
And hope you are not using any module relative URI, because this is what Struts Docs says about html:link forward

The base URL for this hyperlink is calculated based on which of the following attributes you specify (you must specify exactly one of them):

* forward - Use the value of this attribute as the name of a global ActionForward to be looked up, and use the module-relative or context-relative URI found there. If the forward is module-relative then it must point to an action and NOT to a page.

Yes, It looks into Global ActionForwards and Local forwards can be nested within an <action> element and only available to an Action object when it is invoked through that ActionMapping.

and you post .

..when i click on html:link i get the following exception,
Cannot create rewrite URL: java.net.MalformedURLException: Cannot retrieve ActionForward named search
org.apache.struts.taglib.html.LinkTag.calculateURL(LinkTag.java:479)..



I dont think this exception comes when you click on <html:link tag , This error comes when you load index.jsp, Am I correct ?

You need to put action attribute in html:form tag and the post the server logs entry, which give better view of that particular exception !!

i actually made changes in html tld file ie inside attribute tag i changed the tag <required>true</required> to <required>false</required>
so that attribute in form tag(struts tag) is not mandatory and i can provide submit button and there i can foward it to different/same jsp.
when i use html tag am able to load search.jsp but its not same with struts tag.

No NO, You cant do that ! Its prohibited to change the original schema/DTD unless and until you are not creator of your own Struts TAG !

This Struts TAG has there own working java TAG code, see this file, which comes with exception trace



So when that search.jsp file complies and run (when request comes for it ), The class FormTag.java (for html:form) throws an NPE , cause he's expecting an valid value for "action" variable , but it's not coming at all, because your DTD modifications !
