Calling non-static Java Methods from RPGIV

["David Morris" <David.Morris@xxxxxxxxxxxxx>]

Group,

I have not been able to locate an example that works
showing how to call a non-static Java method. I even
tried the example from the RPG manual. I get RNX0301,
some weird things about this are that the method name
is truncated to four positions (it is defined as 100
in the message definition) and the signature is blank.

The example in the manual is flat out wrong. Here
is the prototype (note that there is not
java.lang.BigDecimal, it should be
java.math.BigDecimal.

D add PR O EXTPROC(*JAVA:
D 'java.lang.BigDecimal':
D 'add')
D CLASS(*JAVA:'java.math.BigDecimal')
D bd1 O CLASS(*JAVA:'java.math.BigDecimal') CONST

Anyway, I corrected the example and still get:

Cause . . . . . :   RPG procedure TSTJDOM in program TSTJDOM/DMORRIS
received
  Java exception "java.lang.NoSuchMethodError: add" when calling method
"add"
  with signature "" in class "java.math.BigDecimal".


Here is my prototype and code:

DbdAdd            PR              O   EXTPROC(

D                                       *JAVA:

D                                       'java.math.BigDecimal':

D                                       'add')

D
CLASS(*JAVA:'java.math.BigDecimal')
D BigDecimal                      O
CLASS(*JAVA:'java.lang.BigDecimal')
D                                     CONST


 C                   EVAL      wrkString = newString('50')
 C                   EVAL      bd1 = newBD(wrkString)
 C                   EVAL      bd2 = newBD(wrkString)
 C                   EVAL      bd3 = bdAdd(bd1: bd2)
