hello, I am new to java programming. I installed the j2sdk on my computer and everything seems fine. I can go to the dos prompt and run an application. I can't seem to compile my java files. When I type javac plus the java file name it returns "Bad command or file name"
is my classpath and /or path in my autoexec.bat wrong?

This sounds like an error in your path.

You can check this by typing path at a DOS prompt. Be sure the result includes the fully qualified name of the directory containing javac.exe. Do a search on javac.exe to verify the directory name.

Hi Anthony,

Welcome to JavaRanch!

If you can type "java" to run an app, but not "javac" to compile it, then perhaps you installed only the "JRE" (the Java Runtime Environment) instead of the J2SDK?

If u use windows system, right click on My Computer --> Properties --> Advanced --> Environment Variables, find the variable named "Path",
and double click on it. In the variable field, add C:\j2sdk1.4.2_04\bin;
