[kepler-dev] Custom actor deployment

[Sivagowri Swaminathan]

Hi all

I am having similar problems trying to deploy a custom actor in kepler alpha 
9.0 version.

I created a folder under kepler-1.0.0alpha9/src/actor and  copied the custom 
actor's manifest and the xml files into it. say it was 
kepler-1.0.0alpha9/src/actor/fileChooserActor -----> name of my actor.

Under kepler/src, I copied the source java files. say it was 
kepler-1.0.0alpha9/src/fpkg -----> The package containing my actor's source 
code. My actor is extended from Typedatomic actor as is given in the 
helloworld example.

I copied the kar files into kepler-1.0.0alpha9/kar folder. I got the same 
error as what Mohana got, say,
The class name you entered was not found in the classpath. Note that the 
class you are trying to enter must be in the classpath from which you 
launched this program:fpkg.FileChooserActor.
I edited the kepler.bat file to add fpkg in the classpath but still I got 
the same error.

Instead of directly pasting the kar files in the folder, i tried to first 
run kepler alpha 9.0 and then as matt and chad suggested, I tried to 'import 
the kar file'.
I got 'error creating the component enty from actor metadata: null'

Can somebody tell me how to deploy a custom actor in an existing kepler 
installation. This is very crucial for me as I have to deploy the actors in 
my project manager's machine which also has kepler alpha 9.0.

Thanx
Siva
