ok i downloaded the java development kit (JDK) from the SUN website which included the Java Runtime Environment (JRE).

all i am looking to do is compile a .java file i have into a .class file. is there some site (which uses the latest version of the compiler) that will let you submit the .java file and spit back a .class file?

 All you need to do is to use the javac command to do it. If you have a program called MyApplication.java you need to do: javac MyApplication.java and this will give you the MyApplication.class file which you can run by doing a: java MyApplication

  Hope it helps.

look at the directory where you installed the java.

 make sure that the directory "JAVA_INSTALL_DIR/bin" is in your path.

 make sure that the file "JAVA_INSTALL_DIR/jre/lib/rt.jar" and "JAVA_INSTALL_DIR/lib/something.jar" (i don't recall right now which one) are in the CLASSPATH.

On Windows:
 set CLASSPATH=path_to_rt.jar;path_to_something.jar

On Linux:

  export CLASSPATH=path1:path2


  If it fails, post here the configuration of your JDK installation (OS, path of installation etc)


HIH,

why doesn't the JDK automatically create these settings when it installs? also is there a visual studio version for Java (i.e like microsoft's Visual Studio) created by SUN or some other company?

quick question about experts exchange. why doesn't it let you assign partial points? i am going to give the points to "s_lavie" because the link he provided was for an excellent tutorial but "mgaurav" also gave a good answer.

MS has the VJ++
Borland has the JBuilder
And many more...
