Hi,
I have been trying to bundle up my application into a jar file using JBuilder 3.5 Deployment wizard. I am working off an Oracle data base and am using a jdbc thin driver.
The problem is that when I try to run the app I get a ClassNotFoundException for oracle.jdbc.driver.OracleDriver.
I have put classes12.zip on the classpath.If I replace the jar file with the class files of my app, without changing the rest of the classpath, the app runs fine.
I have even tried to unzip classes12.zip and added them to the jar file,but this does not help either.
Any suggestions?
Thanks in advance.
Shilpa

An addition to the above post, I can run the jar file by running its class.
I can do this -
java test.jar mainclass
where mainclass is the main class in test.jar
but I get a runtime exception when I do this-
java -jar test.jar.
This is using jdk1.3.
