JAR Files and no classpath
Hi.
I've never used jar files in the past, but netbeans 4.0 packages the files so nicely :)
Problem is, you can't use any external jar files in the classpath. This really is a problem if you want to include JDBC drivers or anything else for that matter. Adding the classpath to the manifest file also didn't work.
I finally ended up unjarring oracles jar and adding all the classes into my jar file. Works fine now, just a "fat" installation.
Are there any easy ways around this? Maybe like setting the classpath at runtime before the driver gets initialized?
Thanks!

Look at the javadocs for jar.exe to see how to do it without NetBeans. You should know how to do it and what NetBeans is putting in there for you.

Wrong.

Yes, it does. Add the CLASSPATH and deploy the 3rd party JARs with your JAR.

Terrible idea, even if it "worked". You shouldn't unpack 3rd party JARs. Better to learn how to do it correctly.

Yes - learn how CLASSPATH works. Is your problem using an executable JAR? Study up on that.
