RE: JVM RunUnit - Call (String, Object []) Problem

Hello,

based on your answer I have tested two ways

int SExtUebergabeLen = 815;
SExtUebergabe sExtUebergabe = new SExtUebergabe();
int SUservgIoLen = 4711;
SUservgIo sUservgIo = new SUservgIo();

RunUnit runUnit = new RunUnit();

XUSERVG xuservg = (XUSERVG) getCallable(); // creates an instance of XUSERVG
runUnit.Add((IObjectControl) xuservg);
retValue = xuservg.XUSERVG(SExtUebergabeLen, sExtUebergabe, SUservgIoLen, sUservgIo);

This works like a charm but runUnit.Call is not working (or at least I do not understand how to use it) so :

int SExtUebergabeLen = 815;

SExtUebergabe sExtUebergabe = new SExtUebergabe();
int SUservgIoLen = 4711;
SUservgIo sUservgIo = new SUservgIo();

RunUnit runUnit = new RunUnit(); // XUSERVG is not instanciated and added to the RunUnit

Object params [] = {SExtUebergabeLen, sExtUebergabe, SUservgIoLen, sUservgIo};
retValue = runUnit.Call("de.lv1871.cobol.XUSERVG", params);

Is resulting in the exception:

com.microfocus.cobol.program.COBOLProgramCallException: 181 Invalid parameter error [package de.lv1871.cobol.XUSERVG]

(argument type mismatch)

......

runUnit.Call would be much easier for me. I have LOTS of Calls to Cobol and I could make great use of the more generic Method "Call".

Kind regards
