java.lang.NoClassDefFoundError

[jrookie]

Hi
I keep getting error below when running my program (readerwriterserver.java). It compiled without any problem though. Any suggestions?

OS: Win2k
Running jdk v1.2
Environment set = c:\jdk1.2\bin

Exception in thread “main” java.lang.NoClassDefFoundError: readerwriterserver/java

try setting your classpath when running your code, ie -

java -cp .;C:\ readerwriterserver

also make sure when running the command java that you don't have this:

java readerwriterserver.java

it should be

java readerwriterserver

hope this helps.

I had a similar problem, and although being a newbie @ this, found that it was because my class didn't actually do anything.
e.g. if you are making a swing window and dont intialise the container, logically nothing exists, so a class def error occurs.

I'm still in my first year of comp sci, and havn't covered the JVM in detail, but it basically means the JVM cant find anything to display/do...hope it helps. thought id just mention it.
