Chris,

I don't see where you're instantiating the em object. You have declared
it, but not filled it. I would think your find would throw a null
pointer exception.

Subject: Help calling java from RPG

Hello,

I am creating a RPG program that calls multiple Java method from RPG and
am having problems with one of them. In the code snippet below I am
wondering how to set the hxplvl6Class field to the propper value? in
Java I would just use the following: "Hxplvl6 hxplvl6 =
em.find(Hxplvl6.class, l6number);"

D em...
D S O CLASS(*JAVA:
'javax.persistence.En+
D tityManager' )

D HxpLvl6 S O CLASS(*JAVA :
'java.lang.Object' )

D hxplvl6Class S O CLASS(*JAVA :
'java.lang.Class' )
D l6Number S O CLASS(*JAVA :
'java.lang.Object' )

D find PR O CLASS(*JAVA :
'java.lang.Object' )
D EXTPROC(*JAVA :
'javax.persistence+
D .EntityManager' : 'find' )
D pmClass O CLASS(*JAVA :
'java.lang.Class' )
D pmKey O CLASS(*JAVA :
'java.lang.Object' )


/Free
HxpLvl6 = find(em:hxplvl6Class:l6Number)

Thanks for any help,

Chris
