I created little HelloWorld example and I am having problem running it from command prompt (on Windows). When I attempt to run it by:
java tcpServer from command prompt I get NoClassDefFoundError
I am able to compile it with javac, and class file gets generated.
Somewhere I was reading that I have to put path to my class folder into CLASSPATH environment variable. I've done it and rebooted machine, but I still get the same error.
I also was trying to run it by java -cp c:\MyFolderWhereClassFileIs HelloWorld, it doesn't work.
I've looked into ENV variables and I have following: JAVA_HOME: C:\Program Files (x86)\Java\jdk1.6.0_26; JRE_HOME:C:\Program Files (x86)\Java\jre6; CLASSPATH: C:\HelloWorld;
So, how do I run this? Any ideas how to resolve this? Thanks.
PS. The most annoying thing to me is, if I create java project in eclipse, and create HelloWorld example, then it runs fine...
UPDATE:
Here is the code. It does have package specified.
package test.com;
public class HelloWorld {
public static void main(String[] args) {
System.out.print("Hello World");
}
}
My HelloWorld.java and HelloWorld.class files are here: C:\workspace\TestApp\src\test\com
One thing I learned so far is that I can't run it from within com folder or test folder. I have to be in src folder class file can be found... but I am still not able to run it... always the same error.
