Michael,

Thanks for your reply. I havn't got the hang of adding to an existing
thread in this forum, I keep starting a new one.

My problem seems to be the same as Jesse's, Fernando thought it might be
a bug but I'm not sure if that was proved.

I have been having a problem with a web service loading a package
downloaded from JBRMS.

When I try this from a simple main method :

  package com.fs.pidp.risk;

  import org.drools.util.BinaryRuleBaseLoader;

  public class readPkg {

    public static void main(String[] args) {

      readPkg rP=new readPkg();

      rP.methodReadPkg();

    }

    private void methodReadPkg(){

      String curDir = System.getProperty("user.dir");

      System.out.println("curDir-"+curDir);

      String curPath = System.getProperty("java.class.path");

      System.out.println("curPath-"+curPath);

      System.out.println(new java.util.Date());

      try{

        BinaryRuleBaseLoader loader = new BinaryRuleBaseLoader();  

        loader.addPackage( this.getClass().getResourceAsStream(
"/pMessage.pkg" ) );

        System.out.println("readPkg.methodReadPkg - end");

      }

      catch(Exception e){

        System.out.println("readPkg.methodReadPkg,
Exception="+e.toString());

      }

    }

  }

this is with the pkg pMessage.pkg in the directory
D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg

and the class Message.class in
D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\com\fs
\pidp\risk

it loads ok :

When I try this from a simple web service :

    } 

    @WebMethod
