Re: No protocol: org/helloworld/HelloWorld.xml by Ron Mak, last updated: Jan 21, 2011 05:12 PM: I did the tutorial "Developing a Hello World Actor using the Kepler Build System and Eclipse". At the end, I was able to start Kepler with "ant run", instantiate my new HelloWorld actor, and use it in the workflow as per the tutorial. However, if I start Kepler from within Eclipse and then try to instantiate the HelloWorld actor (via Tools ==> Instantiate Component), I get an error dialog about Kepler not finding the class org.helloworld.HelloWorld because there is no protocol org/helloworld/HelloWorld.xml. I've copied the stack trace below. Doing the tutorial did not create a file HelloWorld.xml that I could find. Why is it possible to create the HelloWorld actor if Kepler was started by "ant run" but not if Kepler was started within Eclipse? Are there steps that you must do in Eclipse that are missing in the tutorial? Here's the stack trace: com.microstar.xml.XmlException: XML element "entity" triggers exception. in [external stream] at line 1 and column 72 Caused by: ptolemy.kernel.util.IllegalActionException: Cannot find class: org.helloworld.HelloWorld Because: -- no protocol: org/helloworld/HelloWorld.xml -- XML file not found relative to classpath. --

Re: Adding actors and web services by Jianwu Wang, last updated: Jan 19, 2011 09:36 AM: 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.

Re: Adding actors and web services by Daniel Crawl, last updated: Jan 19, 2011 09:19 AM: 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.

Adding actors and web services by madhavi, last updated: Jan 18, 2011 08:31 PM: 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?

Kepler 2.2 Release Roadmap by Ilkay Altintas, last updated: Dec 07, 2010 12:16 PM: This is a roadmap for the release plans for Kepler 2.2. We currently have broad agreement about the goals and approaches for this release as articulated in this document, but the final document awaits endorsement by the Kepler Leadership Team.
