PONoClassDefFoundError error while running JAVA console app
text
Body
copied!<p>I created little HelloWorld example and I am having problem running it from command prompt (on Windows). When I attempt to run it by: </p> <p><strong>java tcpServer</strong> from command prompt I get <strong>NoClassDefFoundError</strong><br> I am able to compile it with javac, and class file gets generated.</p> <p>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.</p> <p>I also was trying to run it by <strong>java -cp c:\MyFolderWhereClassFileIs HelloWorld</strong>, it doesn't work.</p> <p>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;</p> <p><strong>So, how do I run this? Any ideas how to resolve this? Thanks.</strong></p> <p>PS. The most annoying thing to me is, if I create java project in eclipse, and create HelloWorld example, then it runs fine...</p> <p>UPDATE:</p> <p>Here is the code. It does have package specified.</p> <pre><code>package test.com; public class HelloWorld { public static void main(String[] args) { System.out.print("Hello World"); } } </code></pre> <p>My HelloWorld.java and HelloWorld.class files are here: C:\workspace\TestApp\src\test\com</p> <p>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.</p>
