Hi, This error would be basic one but it's very frustrating to me to debug this, few days ago it use to work. I deployed guvnor 5.1.1 war into web logic 10.3, created package with 4 rules, build and deploy, got package url. Started using package url in properties file and passing file to RuleAgent api, suddenly it started giving HTTP response code: 401 for URL. Any thoughts on this issue would be greatly appreciated. Below is the content of properties file and Client code. {url=http://10.117.39.51:7001/Guvnor5.1.1/org.drools.guvnor.Guvnor/package/com.tmobile.pos.rules/LATEST , name=myrules, username=weblogic, poll=30, newInstance=true, localCacheDir=C:\Installed\workspaces\drools\POC\bin, workspacepath=C://bea/user_projects/domains/posdomain, password=weblogic123, enableBasicAuthentication=true} Error: RuleAgent(myrules) INFO (Fri Nov 26 15:19:00 IST 2010): Configuring with newInstance=true, secondsToRefresh=30 RuleAgent(myrules) INFO (Fri Nov 26 15:19:00 IST 2010): Configuring package provider : URLScanner monitoring URLs: http://10.117.39.51:7001/Guvnor5.1.1/org.drools.guvnor.Guvnor/package/com... with local cache dir of C:\Installed\workspaces\drools\POC\bin RuleAgent(myrules) EXCEPTION (Fri Nov 26 15:19:01 IST 2010): Server returned HTTP response code: 401 for URL: http://10.117.39.51:7001/Guvnor5.1.1/org.drools.guvnor.Guvnor/package/com....
