first of al, what version are you using? /jbpm is old (3.1) , it currently is /jbpm-console.
Thanks for the help..! Actually this issue realted to port problem .
My machine is already using the port 8080 .So I have changed the port number from 8080 to 8088 [server.xml].Now its works fine.
How do react if you get the error :
//jbpm - must refer to client 'guest
Steps to resolve the issue
Solution 1 : Dont try with jbpm in the URL ,instead try with jbpm-console[In the latest version console name has been changed ]
Solution 2 :
1 .Download the jbpm suite 3.2.2
2. Go to Eclipse -Windows -Preference and select the Jboss Jbpm
3. And then click the runtimelocation and mention the location of jboss suite 3.2.2
4 And click the Server deployment and change the port number to 8088
5 .Now create a new project .
6 Go to jbpm-jpdl-3.2.2\server\server\jbpm\deploy\jbossweb-tomcat55.sar
7 Open the server.xml and change the port from 8080 to 8088
8 Now deploy the application and open the console
it's not only the latest minor verion (3.3), but it already changed in 3.2
