BC4J Java portlet anyone?

Question

Hi,
Has anyone managed to write a BC4J Java portlet? Or for that matter a UIX Java portlet? I have found some info on writing a Struts based Java portlet but nothing on either BC4J or UIX.
Thanks,
Steve

I have converted a three page bc4j jsp application to three portlets in 902618 version of the portal. But i was feeling lazy to remember all the steps i had to go through..but then i found these steps in Oracle9i Application Server Developer's Guide.
chapter 9 - Running in a Portal Framework
Looks like they have got most of the steps if you want to turn your application into portlets.
Here is a cut and paste for you..
--------------------xx------------------------
You need to add some calls to the JPDK API to make your application run in a portal environment.
Update the links where you want to display another page within the portlet. If the file that contains the URL is an HTML page, you have to change it to a JSP page because you need to determine the URL dynamically.
See Section 9.4, "Update the Links Between Pages Within a Portlet".
Invoke the include method instead of forward. You have to use include because the portal needs to add data from other portlets. If you use forward, the portal does not have a chance to gather data from the other portlets.
See Section 9.5, "Use include instead of the forward Method".
Use the portletParameter method in the HttpPortletRendererUtil class to ensure that request parameters have unique names. This ensures that applications on the portal page read only their parameters and not parameters for other applications. This also enables applications to use the same parameter name; the method prefixes parameter names with a unique string for each application.
See Section 9.6, "Protect Parameter Names".
Make all URL paths absolute paths using the absoluteLink or the htmlFormActionLink method in the HttpPortalRendererUtil class, depending on the HTML tag.
See Section 9.7, "Make All Paths Absolute".

This might give you a starting point.
