If you type set on the command line, does the path statement include a location where javac.exe can be found?

In C:Program FilesJavajre1.5.0_05bin , I don't have javac.exe. I have javacpl.exe . Is that the same thing with a different name? Anyway I tried that name in command line, and it still didn't work. I should move HelloWorldApp.java to the bin folder? I'll send this and try that. -- )|||(__ Nehmo __)|||( Back to top Andrew Thompson Guest Posted: Mon Oct 24, 2005 2:05 am    Post subject: Re: Simple Command Prompt Problem (Learning Java) [email]nehmo54 (AT) hotmail (DOT) com[/email] wrote: Quote: In C:Program FilesJavajre1.5.0_05bin , I don't have javac.exe. - That is the run-time environment (jre) rather than the (Java) developers kit (jdk).
