RE: Servlets / Classpath

["Richard Dean" <rddean@xxxxxxx>]

In theory it is easy to do.  You create your java program, move the .class
over to the AS/400 and then run it.  But you left out a lot of information.
Assuming that you have Java on your AS/400, and you realize that none of the
GUI classes will work, then it is not to difficult.  With out knowing what
you are wanting to do, I can tell you this you can write a "HelloWorld"
program using "System.out.println" in VAJ.  Then copy the generated .class
file to the AS/400.  Sign on to the AS/400 type STRQSH.  Then type "cd
<folder>", replacing <folder> with the name of the folder you put your
HelloWorld pgm in and then execute like you would on your PC in dos.  Type
"Java HelloWorld" and you should have the first step accomplished.  The next
step is what killed me, and that is setting up the classpaths correctly, but
worry about that later.

Let us know if you get stuck.

I feel like I am jumping into the middle of this thread without knowing all
of the background so I am sorry if I repeat what someone has already
posted.  From the last couple of appends I think there are two key points:

1) Environment variable identifiers are case sensitive.  There is a chance
you set the "classpath" environment variable.  That isn't what you want.
You want to set the "CLASSPATH" environment variable since the JVM looks
for classpath in all uppercase.  In fact, you can have multiple environment
variable that differ only in case.  From a green screen do "addenvvar
classpath abc" and "addenvvar CLASSPATH abc", then do wrkenvvar.  You will
see two environment variables.  Assuming the Toolbox LP is installed on
your AS/400, setting "CLASSPATH" should fix up QSHELL.

   Note -- you can also set classpath in QSHELL using the export command.
   Once in qshell, enter
      export CLASSPATH=/path1/path2:/path1/x.jar
   The path separator is the forward slash and the element separator is the
   colon.  CLASSPATH must be uppercase

2) Number 1 should help you in qshell and the Java command, but it does you
no good in WebSphere.  WebSphere doesn't use the classpath environment
variable.  To change classpath in WebSphere, edit jvm.properties (WebSphere
1.x) or bootstrap.properties (WebSphere 2.x).

I hope this helps,

Thanks Richard (Dettinger),

I am running V4R4M0 of the O/S. And we are still using WebSphere 1.1.

I tried Classpath:
/QIBM/ProdData/HTTP/Public/jt400/lib/jt400.jar
then
/QIBM/ProdData/HTTP/Public/jt400/lib/jt400.zip
and I still got AS400JDBCDriver not found. I know that there is something
basic that I am missing but I can not figure it out, hopefully letting you
know the release might help.

Thanks in advance,
Richard Dean
