Hey guys, first of all I apologize for the cross-post, but I wasn't sure
where I should post this question... And sorry about the length.

I am working on linking RPG and java programs together. I have written a
couple modules, one for each class I am interfacing. They both seem to work
just fine except for one method. I keep getting:

Message ID . . . . . . :   RNX0301       Severity . . . . . . . :   50

Message type . . . . . :   Escape

Date sent  . . . . . . :   12/12/03      Time sent  . . . . . . :   14:40:56

 

Message . . . . :   Java exception received when calling Java method.

Cause . . . . . :   RPG procedure DOCP_UPLOA in program PDFPGMSNEW/F.DOCPROC

  received Java exception "java.lang.NoSuchMethodError: UploadFile" when

  calling method "UploadFile" with signature

 
"(Lcom.taylor.docgate.Docfile;Ljava.lang.String;Ljava.lang.String;)Ljava.lan
  g.Boolean;" in class "com.taylor.docgate.Docprocess".

Recovery  . . . :   Contact the person responsible for program maintenance
to 
  determine the cause of the problem.

Technical description . . . . . . . . :   If the exception indicates that
the 
  Java class was not found, ensure the class for the method is in the class

  path. If the exception indicates that the Java method was not found, check

  the method name and signature. If the signature is not correct, change the

  RPG prototype for the method, or change the Java method, so that the
return 
  type and parameter types match. You can determine the signatures for all
the
  methods in class XYZ using command QSH CMD('javap -s XYZ').



Now I can call other methods in the class just fine, and I have recompiled
several times. Below is the code I am using. I have talked to our java
programmers and some others who I know deal a bit with java and no one can
seem to find my signature error. DocP, String, and DocFile are defined as
constants for the appropriate class, so 'String' is
'Const('java.lang.String')'.

This is my subprocedure:
     P*--------------------------------------------------
     P* Procedure name: DocP_UploadFile
     P* Purpose:        Upload a file to DocuShare
     P* Returns:
     P* Parameter:      Document => Core DocuShare document information
     P* Parameter:      AuthToken => Autority Token
     P* Parameter:      URL
     P*--------------------------------------------------
     PDocP_UploadFile  B                   EXPORT
     DDocP_UploadFile  PI
     D  objDocP                        O   Class(*Java: DocP)
     D  Document                       O   CLASS(*JAVA:DocFile)
     D                                     CONST
     D  AuthToken                      O   CLASS(*JAVA:String)
     D                                     CONST
     D  URL                         500A   CONST
     D                                     OPTIONS(*VARSIZE)

     D uploadDoc       PR              O   ExtProc(*Java: DocP:
'UploadFile')
     D                                     Class(*Java: 'java.lang.Boolean')
     D  Doc                            O   Class(*Java: DocFile) Const
     D  AuthToken                      O   Class(*Java: String) Const
     D  URL                            O   Class(*Java: String) Const

     D boolean         S               O   Class(*Java: 'java.lang.Boolean')

      /FREE

       monitor;
         boolean = uploadDoc(objDocP: Document: AuthToken:
#cvtToString(URL));
         return;
       on-error *all;
         return;
       endmon;

      /END-FREE
     PDocP_UploadFile  E  

And this is my java method:

Public boolean UploadFile(Docfile objDocFIle, String authToken, String url)
throws DocgateException{  
   return objDocgateDAO.UploadFile(objDocFIle,authToken,url);        
}

If you see anything wrong or have any other ideas. Please let me know. I am
starting to loose hair over this.
