Hi Colin;

The Item class is in the jar. The package name is rpgExample.

I viewed the structure of the jar by copying it to a zip file and opening the zip file.

rpzExampleJar.jar
META-INFO
MANIFIST.MF
rpgExample
GetItem.class
GetItem.jar
Item.class
Item.jar
folders for other projects in the Eclipse workspace.

So your code is looking for fully qualified rpgExample.Item.

Is this inside your classes folder in your jar?

I am trying to call Jave from RPGLESRC. I keep running into RNX0301

I tried for two days to get past this error with my own class and RPG.
Yesterday I decided to see if I could make RPGLE and Java work
together with an example from the Internet.

This is a well thought out example.

I wanted to eliminate coding errors in my RPGLE and Java, to minimize
the possibility that this is a signature error. Still getting the same error.

I created an Eclipse project, rpgExample. I copied the Java source
from the example into two files, Item.java and GetItem.java. In
Eclipse I exported them to the IFS as a jar file, named
rpgExample.jar. The destination was /iasp1/java/prcExample. So now I
have the jar in /iasp1/java/prcExample/rpgExample.jar.

I create the RPGLE program as BLALOCK/QRPGLESRC (PRCPWDIRG). I
changed the package name from "com.as400samplecode" to match my
package name of "rpgExample" in both Java and RPGLE.

I used this statement at the top of the RPGLE program:
cmdString = 'ADDENVVAR ENVVAR(CLASSPATH) ' +
'VALUE(''/iasp1/java/prcExample/rpgExample.jar'')' +
'REPLACE(*YES)';
runCmd(cmdString);

I checked the value of CLASSPATH after executing the program with
WRKENVVAR. The value was
CLASSPATH
'/java/prcExample/rpgExample.jar'
That is what I expected. I checked the CLASSPATH with WRKLNK. It was
found.

The execution fails with the RNX0301 error.

I cannot understand what is going on. I'd appreciate some advice. I
can send the source code to you.

Thanks
