Re: [Wrapper-user] Adding -Djava.system.class.loader=... parameter?

[Lars S. <Lar...@if...>]

Hi Leif

I have come a bit closer to a solution. I can now start the service with 
the batch file. I can also start my application when I copy the command 
line into a command prompt window AND my command prompt window is in the 
directory where the service is located, if I try to execute the command 
line from a different location I get the ClassNotFoundException.
Is there a way to ensure that the service is started from the location 
where the service is located? I mean the classes can only be found if 
they are present and the classpath is relative to the current location.
