Error while rendering portlet

Question

I have a standalone oc4j_portal instance on my pc.
Applications deployed to this and then registered in portal as a provider work fine.
My problem comes when i deploy the application to our 10g app server, and try to run a portlet registered against the app server.
The application log contains the following ...

Is it a jpdk , library issue ?
Can anyone help

Answer 1

Hi,
This is a JPDK library issue. The class NameValuePair was deprecated and in the release of JPDK904, the class was entirely dropped. It has been replaced with NameValue class. Looks like the stand alone OC4J instance is equipped with JPDK 902, and your Portal definitely has JPDK 904. So you will have to change all reference of NameValuePair to NameValue.
HTH,
