Could not invoke the service() method on servlet
xy...@cam.ac.uk
I have developed a file upload JSR-168 portlet "MyJSR" and it works fine
with Pluto.
Then I'd like to deploy it to WebSphere portal.I have now successfully
installed the portlet to WebSphere Portal 5.1.0.1. Under
"PortalServer/installedApps/MyJSR_PA_1_0_CH.ear/MyJSR.war/WEB-INF", I can
see all required classes, JARs and jsps,etc.
But when I upload a file, it dose not work. I checked the log,I found the
following error message(See at the end of the email). Basically
processAction()is working. I can System.out.println("Hello world!!!")".
But when creating an instance of a class, it throws an exception ".....
java.lang.NoClassDefFoundError:". I double checked and can make sure
that all the required JARS are included in
"PortalServer/installedApps/MyJSR_PA_1_0_CH.ear/MyJSR.war/WEB-INF/lib".
Can you help me, please ?
Thanks you.
Best regards
Kevin
