Re: FileNotFoundException when running JAR Application through jSwat

Yes, the application is actually installed in C:\Program Files\CF EMS\
The directory structure underneath 'CF EMS' looks like so
CF EMS\data
CF EMS\diagrams
CF EMS\jre1.3.1
CF EMS\images

There's a JAR file in the 'CF EMS' directory which I execute to start the
application. In jSwat the command looks like so (in the 'Start VM' dialog
box)

Class name and arguments:
com.cratersandfreighters.ems.EMSLauncher

I have the following paths for my Classpath in jSwat:
C:\Program Files\CF EMS\cf.jar (this is the jar for the application and has
the 'EMSLauncher' class)
C:\Program Files\CF EMS\jdom.jar
C:\Program Files\CF EMS\mysql.jar
C:\Program Files\CF EMS\xalan.jar
C:\Program Files\CF EMS\xerces.jar
C:\Program Files\CF EMS\gemini\BCEL.jar
C:\Program Files\CF EMS\gemini\debug.jar
C:\Program Files\CF EMS\gemini\dom4j.jar
C:\Program Files\CF EMS\gemini\GeminiJavaAPI.jar
C:\Program Files\CF EMS\gemini\wasp.jar

Do you have a solution that I can try out?

Thanks for the reply!
