Re: RUNJVA problems -- JAVA400-L

I am not getting a clear sense of what the first NoClassDefFoundError iscaused by. It is either a classpath issue or a class naming(misspelling or a case sensitivity issue).

Just remember that the classpath is not like a path environment variablein that just path references are in the list. My experience has beenthat classes and jars need to be specifically identified in the path.Just listing the folder is not enough when the class you are running iswithin a jar.

If you have something like C:\myjars in a classpath and want to load aclass from the my.jar file from it, you can't just have C:\myjars on theclasspath. You need C:\myjars\my.jar on the classpath. Perhapssomething in your program is referencing a class file that is containedwithin a jar. In that case, you'll need to add the complete path to thejar, with the .jar extension, to the classpath.

Mike,

I didn't see you get a response for this.  Did you?
If the NoClassDefFound error on the "lockbox" program or is it onsomething else? Or is "lockbox" just a folder?
You could add the current directory to the classpath by adding a ":." to
the end of the CLASSPATH parameter. What folder was your "Hello" classin when you successfully ran it?

I have created a java program that I am trying to run from a CL usingthe RUNJVA command. So far unsuccessfully. I think I have a problemwith my classpath, but I just can't figure out why.
I have successfully run this.
RUNJVA CLASS(Hello) CLASSPATH('/QIBM/ProdData/Java400')
PROP((java.version '1.4')) OPTION(*NONE)

I ran this just to make sure I had the basics correct.

So I exported from WDSC to    /QIBM/ProdData/Java400/lockBox my java
programs.  UploadLockBox and ConnectDB2.
I also copied jt400.jar to /QIBM/ProdData/Java400
So I have tried to run this command.
RUNJVA CLASS(UploadLockBox)
CLASSPATH('/QIBM/ProdData/Java400/lockBox:/QIBM/ProdData/Java400/jt400.j
ar') PROP((java.version '1.4')) OPTION(*NONE)
But I get java.lang.NoClassDefFoundError


I did not export as .jar file(as I probably should).  I just seem to
for
whatever reason have better luck when I export as 'file system'

I've also tried to run via Iseries Transform and Run, with the same
results.
Any ideas?  I'd be glad to send offline screenshots of my directory
structure - if it would be helpful.
