Hi Tim, Thanks a lot for reply. No I have not received any other replies on my query except you.
As to the first question, it was a typo that there was a ] after nogui option. The error 'Unsupported file type..' that you are facing may be because of the in-compatibility between versions if you have not created the kar file using the same version of kepler you are using to run it. I am not so sure about this point but I have not seen this error. I have debugged the code a bit and found that the org.kepler. KeplerConfigurationApplication at line 173 CacheObjectInterface co = CacheManager.getInstance().getObject(lsid); is throwing the NPE while getting the object. This is because kepler is not able to insert my kar file in its local repository because of the db exception I am getting. Please let me know if you have any luck solving the problem. Thanks a lot again for replying to my mails.

There is a possibly related bug for the build system in bugzilla: http://bugzilla.ecoinformatics.org/show_bug.cgi?id=5381. I just tried running a simple workflow from the command line using Kepler 2.2, and got an error (different from yours--see below) when trying to run a kar, but success when running a workflow exported as xml (moml). In other words, this works: ./kepler.sh -runwf ~/hello.xml And this does not: ./kepler.sh -runwf ~/hello.kar The error message I get for the latter includes the following line: [null] Unsupported file type or connection not available: file:/Users/tmcphillips/hello.kar Tim On Aug 22, 2011, at 10:14 PM, Madhavi Tikhe wrote: Hi, When I try run the workflow using the the kar file using kepler command line, I get the following exception. > kepler.sh -runwf -nogui] workflow.kar Extracting workflow from KAR java.lang.NullPointerException at org.kepler.util.sql.DatabaseFactory.getDBConnection(DatabaseFactory.java:89) at org.kepler.objectmanager.cache.LocalRepositoryManager.<init>(LocalRepositoryManager.java:148) at org.kepler.objectmanager.cache.LocalRepositoryManager$LocalRepositoryManagerHolder.<clinit>(LocalRepositoryManager.java:855) at org.kepler.objectmanager.cache.LocalRepositoryManager.getInstance(LocalRepositoryManager.java:851) at org.kepler.kar.KARFile.cacheKARContents(KARFile.java:567) at com.lifetech.cgr.service.AnalysisControlManager.getManager(AnalysisControlManager.java:136) at com.lifetech.cgr.service.AnalysisControlManager.launchOneAnalaysis(AnalysisControlManager.java:60) at com.lifetech.cgr.service.LifeScopeCommandLineServer.manageOperations(LifeScopeCommandLineServer.java:160) at com.lifetech.cgr.service.LifeScopeCommandLineServer.run(LifeScopeCommandLineServer.java:121) at java.lang.Thread.run(Thread.java:636) Exception in thread "Thread-0" java.lang.ExceptionInInitializerError at org.kepler.objectmanager.cache.LocalRepositoryManager.getInstance(LocalRepositoryManager.java:851) at org.kepler.kar.KARFile.cacheKARContents(KARFile.java:567) at com.lifetech.cgr.service.AnalysisControlManager.getManager(AnalysisControlManager.java:136) at com.lifetech.cgr.service.AnalysisControlManager.launchOneAnalaysis(AnalysisControlManager.java:60) at com.lifetech.cgr.service.LifeScopeCommandLineServer.manageOperations(LifeScopeCommandLineServer.java:160) at com.lifetech.cgr.service.LifeScopeCommandLineServer.run(LifeScopeCommandLineServer.java:121) at java.lang.Thread.run(Thread.java:636) Caused by: java.lang.NullPointerException at org.kepler.objectmanager.cache.LocalRepositoryManager.<init>(LocalRepositoryManager.java:154) at org.kepler.objectmanager.cache.LocalRepositoryManager$LocalRepositoryManagerHolder.<clinit>(LocalRepositoryManager.java:855) ... 7 more I don't have any database installed or configured for kepler.
