Re: [Swarm-Support] From Eclipse to the Command Line

[Kyle Newton]

Thanks for the reply. That does in fact create a jar, which could be
handy for myself in the future. I'm still having the same problem,
though. What I want to do is run my program from within the Linux
command line. I've written my program from within Eclipse on the
Windows XP platform. The tutorials written by the Steves has me setting
classpaths within my code to my .jar that is associated with my current
project. The jar is automatically 'created' by Eclipse and will compile
and run without any funny business. However, when I move those .java
files and the existing .jar to this SuSE terminal and try to compile
and run then I get the following error:

address@hidden:~/beeSim/beeSimNewton> javaswarm StartBeeModel
Exception in thread "main" java.lang.NoClassDefFoundError: StartBeeModel (wrong name: beeSimNewton/StartBeeModel)

I suppose I could go through my code and replace any mention of the
package beeSimNewton with a classpath, but I was wondering if there is
a way to avoid having to do that. It works from Eclipse, how might I
get it to work from the Linux command line? Thank you.

If you are asking how to make a jar file, you collect the class files
from the first command into a jar file like so:

jar cf /my/path/mypackage.jar *.class

adjusting /my/path as appropriate..
