Hi All,

I have developed a J2EE application,

when I run this application through browser,

it gives me error with following message,

<b>

Application error occurred during the request procession.

Details: com.sap.engine.services.servlets_jsp.server.exceptions.WebIOException:

Error parsing [/Calculator/DK_Calculator.jsp] in application [Calculator]. The ID of this error is

Exception id: [000FFE0EF24A004A0001A43200000D800004136C8F8939B8].</b>

Please suggest if anyone can understand,

The response will be highly appreciated,

Regards,

Hi Deepak,

you can use this id: [000FFE0EF24A004A0001A43200000D800004136C8F8939B8] , to find out detailed error message in the trace file:

...\j2ee\cluster\server0\log\defaultTrace.0.trc

Hi Deepak,

the problem maybe that into jsp you are referring to a library that has been compiled with another version of JDK, for example:

<%! name.name.name.name au;%>

<% au = name.name.name.name.getInstance(request,session); %>

The jar have been compiled with a jdk that is different from the one is installed on the server where you are deployng. In this case you need to re-compile the jar using the right version.

Hovewer, read the log from file or from logwiever to understand better the problem.

Hope this help you.

As Rajesh told,

you can uset the C:\usr\sap\J2e\JC00\j2ee\admin\logviewer-standalone\logviewer.bat server side (enter with adiministrator password) or you can use the Visual Administrator -> LogiWiever service in D:\usr\sap\GVD\DVEBMGS01\j2ee\admin\go.bat

To re-compile a Jar take a look to this: http://www.cs.usfca.edu/~parrt/course/601/lectures/java.tools.html or use directly NWDS.

Hi

Would be great if you could check your defaultlog.trc and check for the stack trace
