How to pass the output parameter from Java to RPGLE

[ptnhk]

I have some problem in geting parameters from RPGLE to java. I tried to write a testing CLLE program and use 'JAVA' command to call the class. However, I have no idea how to get the return value from JAVA program back to RPGLE.

Any suggestion ?

Thank you for your help.

I would like to know more about the return parameters.
Can I return several parameters to RPG program ? Or I have to concate all the return parameters to a String and pass back to RPG program?

RPG can accept a fairly large number of parameters either as input from a calling program, or returned from a called program. I'm not exactly sure what the limit is, but I'm sure I've never come close to hitting it.

I return parms from java to RPG by using mutiple getXXX methhods or by concatting the return parms into a string and using a delimeter. It really all depends on how much information you are returning. I personally find it cleaner to use accessor methods.

 * Converts ASCII TO EBCIDIC                                          
D RPGStr          PR         32767A   Varying                         
D                                     EXTPROC(*JAVA:                  
D                                             'java.lang.String':     
D                                             'getBytes')             


TableName = RpgStr( getNextTable( db ) );
SchemaName = RpgStr( getNextSchema ) );
