try this for your groovy script...

Seriously though, in the s= cript you sent, it doesn't look like you declared 'formFilled'.=

At a minimum, declare it with def:

=
def formFilled =3D = new Action("Form Filled")

Hi All,

I am trying to run a g= roovy script from Java and getting the following error

My script looks like this.

//----- These are runnable when run as a = script.
formFilled.execute()
invoke("mailSent"= ;)
</quote><= /span>

If i execute the script directly then t= he last two lines execute and produce the expected Strings printed to the s= tandard out.

<quote>
Doing Form Filled
Doi= ng Mail Sent
</= quote>

I am trying to run it from Java with something like the following.

<quote>
<= div>
Class scriptClass= =3D new GroovyClassLoader().parseClass(new File(Bugger.groovy));
Object scriptInstance =3D scriptClass.newInstance();
scriptClass= .getDeclaredMethod("invoke", new Class[] {}).invoke(scriptInstanc= e, new Object[] {"formFilled"});
</quote>

But I keep getting the No Such property exception. Iv= e looked around for solutions, but either Im missing something so basic its= generally understood, or i haven't found the right part of the interne= t.

So Two questions.=C2=A0

1) why is the property not available / hidden. I don't understand why= its not available to a method within what I expect is the class.

2) what change do I have to make to my code snippets to get= it to work.

(Note: I've created a simple exam= ple of the problem, rather than post my actual code. I am using groovy to d= efine a DSL for describing actions. We then parse a script in that DSL defi= ning different actions. During operation we want to trigger individual acti= ons to execute on certain occurrences)

Cheers
