RE: RUNJVA problems

Not sure that really helps, but I just found something else.  

I just downloaded the EXCELDEMO written by Scott Klement that creates an
excel spreadsheet via RPG/java.   
When I try running it, I have the same problems.  I placed the jakarta
.jar files where Scott indicated.   I wonder if I'm missing something on
my Iseries.  Although I can run the Hello class that resides in the IFS.


I don't know.

Sorry to jump in the middle here, but this works on my machine... if it
helps....  I don't really see anything different between your's and
mine.

RUNJVA CLASS(xsp.xspVectorSQL) CLASSPATH(*ENVVAR)


Where the *envvar  =   :/javaapps:/javaapps/jtds-1.2.jar

Larry,
Your understanding is correct and we have made some progress.

To answer your question UploadLockBox is in a package called lockBox.

So based on what you said I tried changing my RUNJVA statement to the 
following(actually several variations)

 RUNJVA CLASS(lockBox.UploadLockBox)
CLASSPATH('/QIBM/ProdData/Java400/:/QIBM/ProdData/Java400/jt400.jar')
 PROP((java.version '1.4')) OPTION(*NONE)

RUNJVA CLASS(lockBox.UploadLockBox)
CLASSPATH('/QIBM/ProdData/Java400/:/QIBM/ProdData/jt400.jar')
PROP((java.version '1.4')) OPTION(*NONE)

RUNJVA CLASS(lockBox.UploadLockBox) 
CLASSPATH('/QIBM/ProdData/Java400/:/QIBM/ProdData/Java400/lockBox/jt40
0.
jar')
PROP((java.version '1.4')) OPTION(*NONE)

RUNJVA CLASS(lockBox.UploadLockBox)
CLASSPATH('/QIBM/ProdData/Java400/:/QIBM/ProdData/Java400/')
PROP((java.version '1.4')) OPTION(*NONE)


All of which now give me
java.lang.ClassNotFoundException: com/ibm/as400/access/AS400JDBCDriver

So I am fairly certain means its not finding my jt400.jar file, but 
I've tried all numerous combinations.

If you would be so kind, would you write the RUNJVA command as you 
think it should look based on what we know.

Mike,

I hope I have tihs correct - you have your directories as follows:

-Root File System
-QIBM
    -ProdData
        -Java400
             -lockBox
                ConnectDB2.class
                ConnectDB2.java
                UpLoadLockBox.class
                UpLoadLockBox.java

Hello.class exists within the Java400 folder.
Jt400.jar exists within the Java400 folder.

You ran this successfully:
RUNJVA CLASS(Hello) CLASSPATH('/QIBM/ProdData/Java400')
PROP((java.version
'1.4')) OPTION(*NONE)

You then: exported from WDSC to /QIBM/ProdData/Java400/lockBox your 
java

programs. UploadLockBox and ConnectDB2 and copied jt400.jar to 
/QIBM/ProdData/Java400

Then: You 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)

and get: java.lang.NoClassDefFoundError

Question: Is your class in a package? If yes, and th package name is 
lockBoxc then your class is really called lockBox.UploadLockBox. If 
so, then you need to include the directory which contains the  
directory "lockBox" in
your class path not the directory which contains your class file.

The class loader locates classes by appending the full packaged name 
to the classpath entries and looking in the file system for the .class

object. If
your class has a package name of lockBox then it wont be found unless
you
include /QIBM/ProdData/Java400 in your classpath (in place of
/QIBM/ProdData/Java400/lockBox).

Example - for a class within the following package: com.package.name 
You would need to place that class in a directory structure of:-
- com
   - package
      - name

Your class would go into name. You then point the classpath to the 
parent directory of com OR zip them all into a jar file and point the 
classpath to
the directory which contains the jar file. This way, the classpath

PLUS

the
full packaged name will locate the directory which contains your

class.

It
can then be loaded.

This may or may not help. I hope it does.

Cheers

Larry Ducie
