Question

I’ve below entries in struts.xml

    <action name="download" method="download" class="com.pqr.myaction">
        <result name="error" type="redirectAction">callme</result>
    </action>

    <action name="callme" class="com.pqr.myaction">
        <result name="imhere" type="tiles">imhere.tiles</result>        
    </action>

imhere.tiles corresponds to imhere.jsp in tiles & shows “download” link.

When I click download, I’m constructing the URL to donwload the package from & if that is null, I’m returning error & also setting class variable this.errMsg = “ERROR” & then displaying it in imhere.jsp
as shown below:

       <s:if test="errMsg != null"> 
          <div id="normalErrMsg"><p><s:property value="errMsg" escape="false" /></p></div>
        </s:if>

     <a href="/download">
        <s:property value="getText('DOWNLOAD')" escape="false" />
     </a>

But somehow, the control does not go to the above if condition at all.

Can any one tell me what is worng this behaviour?

Thanks!

A redirectAction is just that, a redirect. Request attributes and parameters are lost, because it’s a new request, new action instance, etc.

You can either forward, maintaining the URL in the address bar and staying in the same action, use the "scope" interceptor to temporarily store messages/data, or store the messages in the session yourself and remove them on entering myaction.

In this case I’m not sure I’d bother redirecting, though.
