Classpath and environment problem ? 1

[zephan]

Hi All,
I compiled a java program on a windows PC, it works fine in the IDE. I then copy the entire folder to a Linux server, and it works fine. But when I run the program on my PC from the command line, it does'nt work, even the syntax is the same on linux means java -cp full_path_to/a_jar_file.jar:root relative_path_to_class/classname

The error message is java.lang.NoClassDefFoundError
relative_path_to_class/classname

What could be the error

A directory to much or to less in the classname.

Directory: /somewhere/a/b/c/D.class
Package: b.c
Class: D

cd /somewhere 
java a.b.c.D

Wrong: a is not part of the classname (packagename).

cd a/b
java c.D

Wrong: b is part of the packagename and might not be omited.

cd ..
java b.c.D

Should work.

Also think that directories syntax is not the same in Windos and Linux ...

What do you mean Dianceht, of course I used c:\path_to_app instead of /volume/path_to_app

 

[Diancecht]

What about the relative paths? Keep in mind that / in Windos points to c:

Cheers,

If you're trying to run a jar file, just try:
java -jar path\jarfile.jar
