hi,

C:\FirstJava>java hello
Error: could not open `C:\Program Files\Java\j2re1.4.2_18\lib\i386\jvm.cfg'

One more thing:In my file structure it is "\Java\j2sdk1.4.2_18" not the one mention in the error.ie,"\Java\j2re1.4.2_18"
Please help me....

try "java -version" in the command prompt. It should display the version of the your JAVA Installation. Check you have installed the Java Runtime Environment also.

Hope this helps.

Regards.
