Internal Server Error 500: java.lang.NoClassDefFoundError?

Former Member — Wed, 22 Jun 2005 11:45:39 GMT

Hi,

We have installed the SAP J2EE 620 Engine on our BW3.0B server and have deployed the test application, Hello.ear.

The Java Deploy Tool has indicated that the EAR loaded and deployed successfully, however when we open the application at http://host:port/Hello, we get an Internal Server Error 500.

Is it possible that the J2EE engine is unable to access the directory where the library is stored? That seems to be what the log is saying but I don't understand why.

I have appended the Browser Error and the Server Error log below.

Can anyone suggest how to resolve this problem? I would really appreciate any pointers for resolving this problem.

BROWSER ERROR:

Internal Server Error 500!
