PATH and CLASSPATH in Windows7 7 / Eclipse
- by Richard Knop
So I would like to set PATH and CLASSPATH system variables so I can use javac and java commands in the command line. I can just compile and run java programs in eclipse but I would also like to be able to run them through command line.
This is where I have Java installed:
C:\Program Files (x86)\Java
jdk1.6.0_20
jre6
And this is where eclipse stores my Java projects:
D:\java-projects
HelloWorld
bin
HelloWorld.class
src
HelloWorld.java
I have set up the PATH and CLASSPATH variables like this:
PATH: C:\Program Files (x86)\Java\jdk1.6.0_20\bin
CLASSPATH: D:\java-projects
But it doesn't work. When I write:
java HelloWorld
Or:
java HelloWorld.class
I get error like this:
Exception in thread “main” java.lang.NoClassDefFoundError: HelloWorld
The error is longer, that's just the first line.
How can I fix this? I'm mainly interested to be able to run compiled .class programs from the command line, I can do compiling in the eclipse.
