[rules-users] NoClassDefFoundError for

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\readDownLoadedPk g; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\xs tream-1.1.3.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\an tlr-runtime-3.0.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\co re-3.2.3.v_686_R32x.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\dr ools-compiler-4.0.0.SNAPSHOT.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\dr ools-core-4.0.0.SNAPSHOT.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\dr ools-decisiontables-4.0.0.SNAPSHOT.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\dr ools-jsr94-4.0.0.SNAPSHOT.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\ja nino-2.5.7.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\js r94-1.1.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\jx l-2.4.2.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\mv el14-1.2beta26.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\xe rcesImpl-2.4.0.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\xm l-apis-1.0.b2.jar; D:\bea\user_projects\w4WP_workspaces\workspace1\readDownLoadedPkg\lib\xp p3-1.1.3.4.O.jar Tue Aug 14 01:02:12 BST 2007 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\pid p\risk I get: Webservice Object is being Created!
