Is this on an MS Windows system? If it is, then it should be as simple as going here:\n\nhttp://java.com/en/download/index.jsp\n\n...and downloading and installing the latest Java Runtime Environment.

Possibly its a problem with the Java installed on your system. To fix this just go to java.com and download and install the latest one. If you are using Interet Explorer then you may also want to run 'sfc /scannow' from the start menu. In case of other browsers you may try to uninstall and reinstall the latest version.

You need a newer version of Java.  Go to Sun.com and go to the free downloads section.  I had the same problem, and this fixed it.

Download the plugin from http://www.java.sun.com\n\nDownload the latest version (1.5.0_06). 1.4.2_03 is very old.

Unless you write or use a special or custom class loader class files are loaded from the CLASSPATH.  The can be defined as a environment variable or you can pass it in as a option to the java runtime.  So you don't actually "register" when usuing just the JVM.  If using some Java J2EE applicaitons / servers they will provide a configuration or installation aide that will build the classpath for you.  Without knowing what environment your running on / using I can only point you to the -classpath option at the command line.  \n\nCheers, good luck
