Problem running an executable jar

May 25, 2006 06:10:00

I have been trying to run a jar. There is a manifest file in it. I have 2 other external jars that are to be used by my application namely log4j.jar and db2jcc.jar.
It is throwing a NoClassFoundException saying that the Logger class cannot be found. What am I supposed to add in manifest file. (Carriage Return has been properly given). Am i supposed to add something in the class path.

Please help me in this regard.

Regards

Yes. The other JAR file. You need to add it to the manifest.

I just pulled out one of our exec JAR files for an example. Here's the setting in the manifest:

Class-Path: lib/jai_codec.jar lib/jai_core.jar lib/mlibwrapper_jai.jar lib/jtds-1.2.jar

As you can see we use JAI and JTDS. The JAR files for these are in a folder named "lib" which is in the same directory as the executable JAR. The classpath MUST be set in the manifest, the environment variables and -cp option will be ignored when you use -jar.
