    PCML Specification Errors using JT400

    Greetings!

    My scenario is such - I'm wrapping a Java web service around a set of RPG programs that live on one of my company's i-Series (AS/400) midrange computers. To faciltate the connectivity between the Java application server and the i-Series box, I'm using IBM's Toolbox for Java.

    My circumstances allow me to use previously-written PCML specification files in my code. I can verify that these PCML files are in use in my company's production environment.

    The PCML files work for all but one RPG program, which throws an exception at the ProgramCallDocu ment initialization statement.

    The specific error thrown is -
    Code:
    "File 'getAccountInfo' contains PCML specification errors."
    With the finer details of the exception being -
    Code:
    "Attribute length="9" is not allowed when type="int" is specified....."
...
"Attribute length="9" is not allowed when type="int" is specified....."
...
"Attribute length="3" is not allowed when type="int" is specified....."
    The PCML document has worked in the past, so I'm skeptical that anything is wrong with the document itself.

    A handful of the approaches I've tried to fixing this problem -
    • Changing the PCML version in the PCML document
    • Rolling back to a previously-used version of the JT400.jar library
    • Verifying that the RPG programs output parameter datatypes match those found in the PCML document specification.


    My environment specs -
    • Sun Java System Application Server v. 9
    • J2EE 1.4
    • OS/400 (i5/OS) V5R4


    Any help or insight would be greatly appreciated.

      You said the file worked before.
      When did it start to show the errors? i.e after making which changes?

          The PCML file works in old legacy code (currently running in the production environment), but has never functioned in this new project.

          The file itself remains unchanged.

              Just a silly guess (I know nothing about PCML): what happens if you remove
              that attribute 'lengt="x"'? It seems to me that it's a format specifier of some
              sort like the old COBOL 'pic 999' thing. It makes sense that such a format
              wouldn't make sense for just ints.

              I might be totally wrong though.

              kind regards,

              Jos

                  Yes, sir. I tried changing the length attribute (same error) and removing it entirely (and received a "attribute NULL is not allowed for type int" error message)

                      Does this link help a bit?

                      Sorry that I can't really help you with this; best of luck.

                      kind regards,

                          Well I'm stumped. I wonder if running it with a java 1.4 JVM would help.

                              I will give that a try ASAP and report my results.

                              Oh, and thanks for the link, Jos. It didn't address this particular issue, but it did help me with another unrelated problem I was experiencing.
