Adding actors and web services

Posted by madhavi at January 18. 2011

I have a few questions.

1. I have some existing plug-ins for secondary analysis pipeline and i want to add them as actors in kepler. How can i do that? I have already tried with the hello world program from manual but it is not working for me. I get exceptions about the xmls when i try to add helloworld as actor in kepler.

2. How to deploy kepler web services so that i will be able to start the workflow from my client? In case of web services, how the error reporting and workflow monitoring done?

3. WHen i run the workflow from command like using ant run-no-gui, my workflow runs but then how can see the oupput of it?

Madhavi,
 
1: What exceptions do you get when you try to add the helloworld actor?
 
3: Instead of using the Display actor, you could use LineWriter or FileWriter.

Madhavi, 2: Kepler has a separate webservice module to execute workflows through web service. You can have a look at it at (https://code.kepler-project.org/code/kepler/trunk/modules/webservice/). But it was built in 2009 and some changes might be needed to work with the current Kepler version. The execution error and execution status information can be gotten from web service message.
