    I hope I don't leave any vital information out.

    The OS I'm XP SP1a.
    the JDK version is SE v1.4.2_02

    I'm new to Java and I was using the tutorial provided on the
    java.sun.com site.
    Specifically:http://java.sun.com/docs/books/tutorial/ext/basics/install.html

    I tried javac -classpath some.jar some.java

    The jar and the java file both being in the same dir and I having
    navigated to that dir through the commandline console.

    Having successfully compiled I wanted to try doing it, using the
    <JAVA_HOME>\jre\lib\ext instructions given in the tutorial as an
    alternative to using -classpath.

    Thinking that setting the classpath in that fashion was temporary and
    would live as long as the commandline console was open, I closed the
    commandline console and I could still run the some.class file and
    recompile it without giving it the classpath. Something I did not
    think I would be able to do.

    Thinking that it was in memory, I restarted the system and logged in
    again to XP and I could still run and recompile the said .java file.

    I then went into my environment variable by right clicking on "my
    computer" and going to propeties>Advanced Tab>Environment Variable
    button and I could not fine classpath as an environment variable.

    Where does this env var get stored? I looked in the registry also,
    and it was not there. Is there some java meta file that this
    information is stored in.

    All I want to do is blow it away so that I can the test the
    <JAVA_HOME>\jre\lib\ext part of the tutorial.

    I appreciate your anticipated patients with me.

    Respectfully,
    Gabe
