[kepler-dev] exception when launch Kepler with jars.

[Jianwu Wang]

Hi David and Aaron,

    I tried to launch Kepler with jars of needed modules. I tried the 
following steps and get some exceptions. Any ideas about it? Thanks.

    1) ant jar at build-area: get all jars of needed modules.
    2) copy all the jars and execute Kepler workflow without GUI: java 
-cp 
.;./jars/actors.jar;./jars/core.jar;./jars/loader.jar;./jars/util.jar;./jars/directors.jar;./jars/ptolemy.jar;./jars/common.jar 
org.kepler.loader.Kepler -runwf -nogui -nocache 04-HelloWorld.xml. This 
command works and execute the workflow without Kepler GUI.

    3) start Kepler with GUI: I got an exception with NoClassDefFoundError:

        D:\Kepler\repository\keplerjar>java -cp
        .;./jars/actors.jar;./jars/core.jar;./jars/loader.jar;./jars/util.jar;./jars/directors.jar;./jars/ptolemy.jar;./jars/common.jar

    4) copy the jar and start Kepler with GUI again: I got an exception 
with ExceptionInInitializerError:

      It seems that the Config.xml is not included in the jars. So we 
need put the config file and org.eclipse.osgi_3.4.0.v20080605-1900.jar 
into common.jar when we type 'ant jar' in build-area dir?
