Struts and ADF in Portal

Question

Hello. We have had a TAR going for some time regarding an issue with Struts and ADF in Portal. This is the summary of the TAR:
Customer followed the following document to create his Struts ADF application:
Developing an End-to-End Web Application Using the Default Technology Scope
at
http://www.oracle.com/technology/obe/obe9051jdev/ADFtoJSP/defaultendtoend.htm
After following the steps in the documentation, his application worked just fine.
- After this he decided to portletize his application using the following document:
OracleAS Portal Developer Kit (PDK)
How to create a Struts Portlet ?
at
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/pdkstruts/portletize-your-app.html
When adding his portlet to a page, he basically received a portlet without any data, while the same worked fine outsi
de of Portal.
These are examples from the JSP file that do not show up in the portlet:
<c:out value="${bindings.DepartmentsView1.labels['DepartmentId']}">
<c:out value="${bindings.DepartmentId.label}"/>
</c:out>
We figured out that if we add the following filter mapping then it works fine:
<filter-mapping>
<filter-name>ADFBindingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
This filter mapping would mean that it maps all URLs to the ADFBindingFilter. I suppose this would not be necessary and we're concerned about the implications this might cause and we believe that there should be a better solution for this.
The final reply from support was that Portal is not yet supported with ADF technology. Does anyone have any comment on the above filter issue and other thoughts on using Struts and ADF in Portal? Another issue we found was that the PDK Struts tags do not support EL expressions. Have a look at this forum post:
Re: Struts and nested tags in parameters. Possible?

I am trying to create a portlet with JSF/ADF
I Developed a Application with Oracle ADF UIX from: http://www.oracle.com/technology/obe/obe_as_1012/j2ee/develop/client/uix/lesson_uix.htm
and then I followed this link: http://oracle001.cedecra.it/pdk/articles/pdkstruts/portletize-your-app.html
to portletize the application
and I am getting the below error message:
