I have written my 1st first "HelloWorld" Application. Also the Path is set. Now i am trying to compile the program at the dos prompt with command javac HelloWorldApp.Java. But it is prompting that HelloWorldApp.Java is anb invalid option or argument. Then i tried compiling the same program in C:\JDK1.2.2\Bin directory. Again it was the same error message.
Please let me know how to Proceed further.................

Hi there, could you post your code and what you are exactly typing to try to compile it?
(ie "javac HelloWorldApp" as opposed to "javac HelloWorldApp.java" )
Thanks,

Look at www.javaranch.com/drive and read the part at the beginning about getting your compiler to work.

Thanks bduncan and paul.
I had already taken care of the path variables. Now i had resolve the problem of compiling the source code thru DOS prompt. Actually the problem was instead of command javac HelloWorldApp.java i was issuing the command javac HelloWorldApp.Java and this J vs j was making the difference.
Also the problem which i am facing right now is that even though i being able to compile the program thru DOS prompt i could not able to make thru TEXTPAD. What i am doing in textpad, opening the same source file(which i able to compile successfully thru DOS prompt) and then trying to compile thru <Compile Java> option which is available in the Textpad itself. but textpad also assuming this as an JAVA extension and giving the same error. Please tell me how to resolve this problem.

TextPad is not compiling because even though your saving the file as HelloWorldApp.java, TextPad automaticlly is adding a .txt extenison (even though you don't see it). In order to prevent this put "" marks around the file name, like so, "HelloWorldApp.java". You should be able to compile away.
Hey your writing is hard to understand, I hope I addressed your issue. Good Luck!
