Getting the NoClassDefFoundError in my Dapper Terminal
Heya. So for some reason even though I can compile files within an Eclipse Project, I'm still running into issues whenever I try and do it through the terminal.
trenog@trenog-desktop:~/workspace/helloworld$ javac Hello.java
trenog@trenog-desktop:~/workspace/helloworld$ java Hello
Exception in thread "main" java.lang.NoClassDefFoundError: Hello
This is despite the fact that I'll get the following:
trenog@trenog-desktop:~/workspace/helloworld$ javac -version
javac 1.5.0_11
...
trenog@trenog-desktop:~/workspace/helloworld$ java -version
java version "1.5.0_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_11-b03)
Java HotSpot(TM) Client VM (build 1.5.0_11-b03, mixed mode, sharing)
Anyone got any ideas?

HI trenog
When you work in command line you need to specify the classpath properly.
http://java.sun.com/j2se/1.4.2/docs/tooldocs/solaris/classpath.html
In Many IDEs it take cares of your CLASSPATH.
But when you come to command line you need to specify your system variable CLASSPATH.
in windows peopel use to specify CLASSPATH as
SET CLASSPATH = %CLASSPATH%;.
Dot at the end specify the current path. whereever you run the java command the current path as been take into classpath.
My Recomendation is try to use Apache ANT http://ant.apache.org/ ;) its a nice tool to set all the setting and work with.
ANT - Java programmers best friend :)

So lets say that the place where I've thus far kept my .java files is my /home/workspace/ directory, with each program in its own folder. And let's also say that my java edition could be found in /usr/lib/j2sdk1.5-sun/.
How should I add to my classpath such that all my java files can be run in the terminal, or what should I put to at least get my local folder of java files to run?
Also, as for Ant, I've currently got installed version 1.6.5-3ubuntu1, not that this fact gives me any insight in how to use it.
