System.loadLibrary is how you would load a Windows DLL or Unix SO to call
a native (meaning non-Java) program using JNI.

If you want to call an iSeries *PGM or *SRVPGM you either need to define
it as a StoredProcedure and call it using JDBC or use the AS/400 Toolbox
and the classes it provides for calling programs.  Most people probably
use the PCML method provided in the Toolbox, but the JDBC method is a nice
option if you need to keep your code "light" and do not otherwise need the
Toolbox.  However, if this is running on a non-iSeries system you would
need the Toolbox anyway to get the JDBC driver.

Anyone using java to rpg-modules connections on iSeries???  We have
written an object-oriented RPG program following MVC pattern.  The RPG
program runs fine and now we have written a java program which uses the
RPG modules but displays result in a GUI.

following initialisation is used:
static
{
    System.loadLibrary("PROGRAMNAME");
}
which returns following error when testing class:

java.lang.UnsatisfiedLinkError: no PROGRAMNAME (PROGRAMNAME.dll) in
java.library.path
at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1380)
at java.lang.Runtime.loadLibrary0(Runtime.java:766)
at java.lang.System.loadLibrary(System.java:849)
at Agents.AgentsController.<clinit>(AgentsController.java:35)
Exception in thread "main"


I believe that java is trying to load a local dll in stead of searching
the programmodule on the iSeries but how do we tell java to search on the
iSeries???
