Thread: CMD line is owning me

Ok everyone - I believe that I am having Path issues with my compiler. I have compiled and run code many times. In this case it is the basic helloworldapp in the tutorial. I do not know what to make of this error. I have checked and rechecked my Path and think I am ok. For whatever reason my code still does not compile...


C:\Java>javac HelloWorldApp.java
Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/tools/javac/M
ain
Caused by: java.lang.ClassNotFoundException: com.sun.tools.javac.Main

at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: com.sun.tools.javac.Main. Program will exit.

Is there a place where you can research java errors?

Any help is great!

Thanks.

I was having this problem too, even though I was adding the location to the class path, it was not pickiong it up. Try running the app with the command

java -cp C:\myFolder\ HelloWorld

Ok everyone, I am still having issues with this and am really at a crossroads on this. I am still getting the same error message as I originally posted.

Note - my Path variable has been set properly
Note - my ClassPath Variable has been set properly as well.

Any help would most certainly be appreciated. I tried to copy and paste it into google but no luck.

thank you for your help Junky but it did not work. here is one think that I think is contributing to my problem.

I have jre6 in Program Files (x86)\Java 64 bit

I have jdk1.6.0_29 in Program Files\Java 64 bit

I am not sure why I am having these issues. I mean, it should just compile already, lol.
