Hi,
I am trying to use Cocoon 2.0 in my application on WebSphere 4.0
(Windows 2000). I have enabled security. I get a
'ResourceNotFoundException' when I try to get XML data from a servlet
using the default FileGenerator. The problem seems to be that Cocoon is
not setting the Authentication information on the servlet (as seen from
the Axis TCP monitor tool). Is this is a limitation of Cocoon 2.0 ? Is
there any way I can indicate in the sitemap (or some other resource)
that the authentication information needs to be passed on to the URL
being invoked by the FileGenerator ? I have appended the output from the
Axis TCP monitor tool at the end of this email.
The sitemap snippet which causes the above problem is as follows:
<map:match pattern="Portal/view/tree.xml">
<map:parameter name="parameters" value="true"/>
<map:generate
src="http://pcwes4/myWebApp/myServlet?action=showWBDAndPartsXML&WBDName={name}"/>
<!-- map:transform src="view/tree.xsl"/ -->
<map:serialize type="xml"/>
</map:act>
</map:match>
Thanks,
Sriram
