How does one install the jdom-b5 winzip file from www.jdom.org?

If you are running JDK1.2 or higher versions, you can simply unzip the zip file and copy the jdom.jar into your JAVA_HOME/jre/lib/ext dir. If you are using JDK1.1 then you need to copy 1.1 version of jar file and collections.jar file to JAVA_HOME/jre/lib/ext dir. Also you need to have xerces parser file into your classpath. You can simply also copy the jar xerces jar file(s) in JAVA_HOME/jre/lib/ext dir. If you don't have access to ext dir then simply include these jar files into your classpath.
