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.

The original post was by Jesse Stockall jstockall at embotics.com on Tue Jul 17 08:55:23 EDT 2007

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 :

curDir-D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg

curPath-D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg;

readPkg.methodReadPkg - end

___________________________________________________________________________________________________________________

When I try this from a simple web service :

  package com.fs.pidp.risk;

  import javax.jws.*;

  import org.drools.util.BinaryRuleBaseLoader;

  import weblogic.jws.Context;

  import weblogic.wsee.jws.JwsContext;

  @WebService

  public class WsSimple {

    @Context

    JwsContext context;

    // This is called when WL creates an instance of web service

    public void context_onCreate() {

      System.out.println("Webservice Object is being Created!");

    }

    @WebMethod

    public String loadPkg() {

      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());

      }

      return "/pMessage.pkg";

    }

  }

this is with the pkg pMessage.pkg in the directory D:\bea\weblogic92\samples\domains\wl_server

and the class Message.class in D:\bea\weblogic92\samples\server\examples\build\serverclasses\com\fs\pidp\risk

I get:
