Java compiling question

Quick question about command line java compiling. I wrote a GUI from scratch using NetBeans. I tested it in NetBeans, and everything seemed to compile fine. However, when I tried to compile it on the command line, I got an error saying ClassNotFoundException: javax.swing.JFrame. I'm assuming I have to somehow add the libraries in to the command line compiler, but I don't know how to do that. Any help? Thanks

i guess you got to find out what imports are you doing that aren't in the standart library and then use the -classpath (or -cp don't remember) on the javac options

I'm an idiot. It actually compiles fine, but when I do:

java <file>

that's when I get that exception error. sorry. thanks for your help though

you need to do "java classname" not "java classname.class" this confused me for hours before i found out

haha, yeah, that really is the worst error ever. unfortunately, that is not my error. i'm afraid that this is something trivial, like that other error. ugg ... thanks again though.

You probably need to make sure your classpath is setup correctly. Either with the CLASSPATH environment variable or the classpath parameter for java. (-cp I think, or was that the classpath variable for javac, I never remember...)
