Hi Madhavi,

You could try renaming ~/KeplerData/modules to something else (in case
it contains a bad configuration file) or getting the latest Kepler from
svn.

Hi Dan
The entry you suggested seems right in my kepler.
It is
   <sqlEngines>
     <sqlEngine>
       <sqlEngineName>hsql</sqlEngineName>
       <userName>sa</userName>
       <password>  </password>
       <url>jdbc:hsqldb:hsql://localhost/</url>
       <port>9001</port>
       <dbName>hsqldb</dbName>
       <!--<dbDriver>org.hsqldb.jdbcDriver</dbDriver>  -->
       <!--<jdbcConnect>jdbc:hsqldb:data/hsql/hsqldb</jdbcConnect>  -->
       <SQLDictionary>
...</sqlEngines>

I am launching kepler using its source code and I downloaded the code for 
kepler-2.2 suite.
I am still stuck with the problem. One workaround I implemented which treats 
kar as a jar file file, extracts it and uses the xml from it to launch the 
kepler workflow in headless mode. But the problem with this workaround is it 
will not be able handle the kar file which contains more than one xml (moml) 
files.

Pl suggest.

Thanks for your help,
Madhavi

Hi Madhavi,

Which version of Kepler are you using?

In common/resources/configurations/configuration.xml, you should see
the following entries:

<sqlEngines>
    <sqlEngine>
      <sqlEngineName>hsql</sqlEngineName>
      <userName>sa</userName>
      <password>  </password>
      <url>jdbc:hsqldb:hsql://localhost/</url>
      <port>9001</port>
      ....
</sqlEngines>


Is your<port>  entry empty? If so, try setting it to 9001.

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.

Regards,

Madhavi

Hi Madhavi,

Can you run your workflow from the command line if it is exported as
xml, rather than saved as a kar file? 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/

I don’t have any database installed or configured for kepler. And I
tried executing kepler after clearing the kepler cache. Does anybody
have any idea about the possible cause of this exception and possible
solution?

This exception is blocking my work. Please let me know if there is any
quick fix available.

Regards,

Madhavi
