Pete / Mike,

Thought I'd try too to throw some additional version numbers in the mix for
you.  On our dev system with:

Open Source Software, JTOpen 4.8, codebase 5722-JC1 V5R3M0.9

SF99530                5298  Not installed
SF99529                  67  Not installed
SF99519                 102  Installed
SF99503                   8  Installed
SF99502                  14  Not applicable
SF99314                   1  Installed
SF99301                  12  Installed
SF99295                   7  Installed
SF99290                   2  Installed
SF99269                   9  Installed
SF99173                   3  Installed
SF99169                  17  Not applicable
SF99149                   9  Installed

I also get the ClassNotFoundException error when trying to run it with:
RUNJVA CLASS(lockBox.UploadLockBox)
 PROP((java.version '1.4')) OPTION(*NONE)

Someone else (sorry, don't remember who to give credit) posted that there
is a special classloader for /QIBM/ProdData/Java400/ and this sounded crazy
enough to be plausible, so I tried moving the classes elsewhere, and then
it works fine (well, I get "connection refused" but clearly to have gotten
this far it has loaded the JDBC drivers in fine), i.e. I had the .class
files in /CpaJavaDevelopment/lockBox:
RUNJVA CLASS(lockBox.UploadLockBox)
 PROP((java.version '1.4')) OPTION(*NONE)

Personally my 2 cents though is not to be exporting individual class files.
By the time you get hundereds of class files this must become an
administrative nightmare when it comes to releasing classes from your dev
to production systems and getting the folder structure correct.  Run them
as a JAR file - I think you mentioned you're using WSAD/WDSC and this makes
it so easy (File -> Export -> JAR file).  Then you've just got one file,
you can stick it wherever you like and can use whatever folder structure
you like.  I even tried it in /QIBM/ProdData/Java400/ and this worked fine:
RUNJVA CLASS(lockBox.UploadLockBox)
 PROP((java.version '1.4')) OPTION(*NONE)

Hope this helps,

There are a few variables going here and I am not sure what the key is.

My customer's System i is at V5R3M0 and the Java Group PTF is at level
12.  The toolbox shows:

Open Source Software, JTOpen 5.1.1, codebase 5722-JC1 V5R4M0.2

The example I provided that uses the AS400JDBCDriver works on this box.

My 270 which is also at V5R3M0 and Java Group Level 13 (lucky?) has the
following toolbox level:

Open Source Software, JTOpen 5.2, codebase 5722-JC1 V5R4M0.3

The example DOESN"T run on this box.  I get the same error as you do.

I may try the same jt400.jar as my customer has and see if that works on
my box.

So if this works.

RUNJVA CLASS(utilities.AS400JDBCDriver)
And although this doesn't run- it finds it



It would seem that my problem is maybe in my syntax of the my
Could that be the problem?
 RUNJVA CLASS(lockBox.UploadLockBox)

        PROP((java.version '1.4')) OPTION(*NONE)

Because when I use the above I still get

java.lang.ClassNotFoundException: com/ibm/as400/access/AS400JDBCDriver
