Re: Java assistance please!

["Dr. Syd Nicholson" <sydnic@xxxxxxxxxx>]

This may require help from your vendor.

However, I would start by creating the required directories (OS/400 command
mkdir) and copying the required files into them.

All the java classes will be embedded in the jar files, and the directory
structure might be very important. It depends upon how they have defined
thier java packages and how this relates the the CLASSPATH.

The CLASSPATH is important. It tells java where to find the classes it is
looking for.

You might  need to run this application in a QSH shell, however, it might be
possible to run it from a CL or RPG program using the OS/400 JAVA or RUNJVA
commands. The JAVA command in either environment allows you to specify the
required classpath.

After you copy the files to thier correct locations, try the JAVA command
and see if the application runs. If no luck, go the QSH and try the java
command there. If you are using QSH, runing the java command without any
parameters or specifying a parameter of '-help' or '-?' will display some
help text eplaining the use of the available command parameters.
