Re: Calling non-static Java Methods from RPGIV

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

Group,

I did find an APAR that mentions:

5. When the class for an ILE RPG Java native method is in a
  package, the class name must be qualified.  For example:
        extproc(*java:'MyPkg.MyClass':'mymeth')
  When Java tries to call this native method, the call fails
  because the native method cannot be found.

Hopefully I can download and apply it tonight and it fixes
the problem. Not sure where I report PDF manual problems
to. Also, I don't have software support so I can't report the other
errors I have encountered, I will try to document them and make
that information available with the code when I post it.

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".
