Executing a java .class file from outside the containing folder

[mzatanoskas]

I'm trying to run a java .class file from the command line in XP from outside the containing folder but I'm having trouble making it work.

Say the file is:

H:\Java\HelloWorld.class

I'm at the command prompt in C:\ and I type:

java -cp H:\Java\HelloWorld

I get that class definition not found error. Of course it works fine when I run the file from the same folder.

The reason I need to do this is that I need to run the file from another program, by opening java.exe and passing it the filepath and other arguments.

I hope someone can help, it's probably very basic but it's soooo frustrating! :confused:

Thanks!

The classpath and class name are two different things and hence given as two separate parameters.

Try:
java -classpath H:\Java\ HelloWorld

D'oh!

thanks a lot Zamppa, that worked but I had to get rid of the trailing \ for some reason.
