Bug 819097

Do we already have a way to reproduce without F5 setup ?

We can't exactly reproduce the issue without F5 setup.

Here is what I did:

1) create a filter with the following code:
  public void doFilter(ServletRequest request, ServletResponse response,
                        FilterChain chain) throws IOException, ServletException {
     HttpServletResponse httpResp = (HttpServletResponse) response;
     httpResp.sendRedirect("/eXoGadgetServer/gadgets/redirectapirpc/");
     return;
  }

2) add this filter as the last one in the filter chain in eXoGadgetServer.war/WEB-INF/web.xml:
   <filter>
    <filter-name>myRedirectFilter</filter-name>
    <filter-class>com.redhat.jboss.web.util.filter.RedirectFilter</filter-class>
   </filter>

   <filter-mapping>
    <filter-name>myRedirectFilter</filter-name>
    <url-pattern>/gadgets/api/rpc</url-pattern>
   </filter-mapping>

3) replace every instance of the url-pattern "/gadgets/api/rpc/*" in web.xml with "/gadgets/redirectapirpc/*" (for the JsonRpcServlet servlet mapping and all relevant filter mappings)

Now I'm getting error:

java.io.IOException: Server returned HTTP response code: 400 for URL: http://localhost:8080/eXoGadgetServer/gadgets/redirectapirpc

It indicates that the redirection is not honored by the code.

Actually, it should be adding this filter as the first one in the filter chain.

I'm able to reproduce the exact error in my test case now.

In my previous attemps, I tested the import/export gadget. In this test I used the dashboard to launch the calculator gadget provided by EPP. 

I'm receiving the error message:

Please note that the redirection fails with the shindig authentication servlet just as mentioned in the javadoc [1] "When output streaming is enabled, authentication and redirection cannot be handled automatically." 

I believe the redirection works fine with a normal servlet situation. But it fails with shindig which requires some kind of authentication.

eXoGadgetServer.war servlet filter

I've uploaded the servlet filter used in my test. To use it just place it under eXoGadgetServer.war/WEB-INF/lib and configure it as mentioned in comment #2 as the very first in the filter chain in eXoGadgetServer.war/WEB-INF/web.xml.

We won't be able to fix for 5.2.2ER01. More likely 5.2.2.ER02 but I'm setting GA for now as it is only currently available option in BZ.

I'm not able to replicate the environment and still not able to find out what's wrong with the resources links.
