The Java Archive Tool
Sun Microsystems, Inc.
Typical usage to combine files into a jar file is:
C:\Java> jar cf myFile.jar *.class
If you have a pre-existing manifest file whose name: value pairs you want the jar tool to include for the new jar archive, you can specify it using the m option:
C:\Java> jar cmf myManifestFile myFile.jar *.class
To extract the files from a jar file, use x, as in:
C:\Java> jar xf myFile.jar
To extract only certain files from a jar file, supply their filenames:
C:\Java> jar xf myFile.jar foo bar
Updates an existing file jarfile (when f is specified) by adding to it files and directories specified by inputfiles. For example:
jar uf foo.jar foo.class
would add the file foo.class to the existing jar file foo.jar. The u option can also update the manifest entry, as given by this example:
jar umf manifest foo.jar

JRun Overview of filters
http://livedocs.adobe.com/jrun/4/Programmers_Guide/filters2.htm
Filters process request objects before they get to the server or process response objects after they leave the server and before they are returned to the client. You can use filters to do the following tasks:
Take flow-control logic out of web application components.
Examine and modify the request object before the server receives it from the client.
Examine and modify the response object before the client receives it from the server.
Change the content of the response.
...
Specifically, filters are often implemented as:
Request dispatchers
User authenticators and authorizers
Request and response loggers and auditors
Form validators
Image converters
Data compressors and decompressors
Data encryptors and decryptors
Response output tokenizers
Triggers for resource access
XML transformers
Content localizers

Using the getResource method
http://livedocs.adobe.com/jrun/4/Programmers_Guide/techniques_servlet19.htm
You can use the ServletContext object's getResource method to include content in your servlet. The getResource method returns a URL object. Then you can use the URL object to access the content. One advantage of using the URL object is that you can parse the content before returning it to the browser. You can also use this technique to include content that is otherwise not accessible to the users directly, such as files in the /WEB-INF directory.
