send whole stacj trace, I think you miss some class in your jar that extend your class. Include that class also.On Jan 14, 2008 10:37 AM, Akila Geethal < akilageethal@gmail.com> wrote:java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) atwhat can be the reason for thsi error? am i missing some thing in the jboss server or what can be the error?? I get thsi when i try to import the classes(facts ) from the uploaded jar??And also where does the jar get saved when it is uploaded??On 1/11/08, Rahul Upadhyay < email2upadhyay@gmail.com > wrote:See, BRMS needs only packaging + class file because you are importing that one only. Second why do you create jar of whole project. In project, There will be project name folder, there will be bin folder.. your import statement does not include those. so if you put whole project hierarchy , how will you get the path.. result class not found.. just include package folders + class you want .
All the Best

it works easly.. not big deal.. try
cheers

I have a vague recollection that there is another file in which you need to list your fully qualified class names before they can be referenced by the BRMS.I think Kris (or Edson) has provided a posting to the group before about this.Flame me if I am wrong.

When i try to get the clsses by the import statements it says the class cannot be found. Are there any special way of making the jar?Should that fact modelapplication include special libraries or etc....No it' just a standard jar, with standard pojos.
