Hello All,

I think the problem is at the jbpm3.2.6 only because i have made one test class with the same jar files and its able to load Beanshell , which is not possible in my decision Handler

see my test class has following code

           BSFManager bsfManager = new BSFManager();   
            BSFEngine bsfEngine = bsfManager.loadScriptingEngine("beanshell");

            System.out.println("==> Engine loaded successfully");
            System.out.println("=====>" + bsfEngine.getClass().getName());

this is able to load the bsfengine and prints

==> Engine loaded successfully
=====>bsh.util.BeanShellBSFEngine    

while in decision handler

  BSFEngine bsfEngine = this.manager.loadScriptingEngine("beanshell");

this code is throwing exception with  message

Unable to load Language : beanshell

and log this exception

  org.jbpm.JbpmException: couldn't get value for file 'classes/java/lang/bsh.class'

I am using following jars..

bsh.jar

bsf.jar

bsh-2.0b2.jar

Any one have idea about this painstacking issue ??

Thanks

I resolved the issue by my self, for those who are facing the same problem , i am writing solution for them,

Actually In a decision handler when you try to initialize the beanshell engine , you have ProcessContextClassLoader but actually you suppose to have webContextClassloader so it is not able to load the BeanShellEngine because it is not able to find the relavent classes that are available in a jar for beanshell. You actually have WebContextClass Loader , following code in decision handler will work

ClassLoader oldClassLoader = Thread.currentThread().getContextClassLoader(); // This code will give you ProcessClassLoader

Thread.currentThread().setContextClassLoader(Thread.currentThread().getContextClassLoader().getParent());

//Above line will set  WebContextClassLoader in current thread's classloader now you can write you Beanshell related stuff

and finally in finally block you can set your class loader to

     Thread.currentThread().setContextClassLoader(oldClassloader); // that is your processClass Loader

Is there any Bug in JBPM3.2.6 SP1 , Is it resolved ? if Yes then which version should i take ?

Thanks
