Hi,
I'm using third party library- JFree Chart Libraries
These jar file are placed in /WEB-INF/lib .
But when i deploy the app as war file on weblogic 9.2, the server throws following exception and the graphs are not generated:

This application runs fine when running through JDeveloper IDE and its inbuilt OC4J application server.


Kindly help.

Maybe the jar file was corrupted during the move.
Did you inspect it with the jar command?

 
cd WEB-INF/lib
jar -tvf jarFile.jar

This will dump the names of all the files (with directory structure) in the jar archive.

I have not worked with jFreecharts..but does that have any other .jar in the bundle or that is the the only jar required to work with.If yes then try downloading that again.the version that you are using might be bad.

Hi,
I guess you are deploying your war file using the JDeveloper.

I you add the third party jar in ProjectProperty >> Profiles >> Development >> Paths it will work in JDeveloper, but when you deploy (if you are deploying through JDev) the jar file won't be taken to WEB-INF/lib.

Make sure the third party jar file is included in ProjectProperty >> Profiles >> Development >> Libraries. In this case the jar file will be taken to the proper directory.
