For some reason, after I'm installing my JRE, the class path is not set automatically. When I type javaw on the prompt (c:\>javaw) I get the error message �not recognize as an internal or external command.
I tried in the environment variables � system variable � And on the variable name: classpath Variable value: C:\Program Files\Java\j2re1.4.2_09\bin;
This didn�t work. Does anyone know how to set the classpath correctly?
The error "not recognize as an internal or external command" means that Windows can't find javaw.exe, not that Java can't find classes (which is what CLASSPATH is for.) Windows uses a different environment variable named PATH to find programs. The JDK "bin" directory does not belong on the CLASSPATH, but it does belong on the PATH.
The very best setting for CLASSPATH for a new Java user is -- by a wide margin -- to not have it set to anything at all. The default is just perfect.
You need to add the bin directory to the PATH variable. As noted above, this problem has nothing to do with the CLASSPATH variable. For instructions on how to do this, see step 5 in Sun's Installation Instructions.
