Getting servlet context in a web service

Question

Hi,
I have a problem but have no solution to it and am not sure of the approach.
I am creating a web service. Some parameters will be passed to this web service. I need to capture these parameters and put it in a hash table so that it is available to another applicatins servlet context i.e.
there will be two calls .
first the web service is invoked and the parameter is stored in the hash table of the applications servlet context.
Next when the application is invoked it shud refer to the hash table and get the data in the hash table that was stored by the web service and process it.
How can this be achieved?

Well, some experts will wanna kill me for told that, but, lets go....
Comparing with the JVM, a context is like a class path (of course they have many differences). In other worlds the context is a directory (or war file) where the web server (for example TOMCAT) wiil search your .class files (or.war, .jar, etc...)
All context are "pointed" to a dir, for example you can point the context /myapps to a dir of your OS (for example /home/your_username or in a windows system - C:\Program Files.
Then when you acces this context at the browser, the browser will show this directory hierarchy. For you execute your servlet you need to create a WSDL (the descritor file). This file is nothing more than a XML document (that had rules) and link a servlet at a context, (for example the servlet Hello can pointed to the path /hello, and then, this servlet is "install" at the context /myapps). After this, you can access your servlet at the path http://computer_address/myapps/hello.
Note: Step by step, you need:
1) create the web application strucuture directory (the WEB-INF, classes, etc...)
2) write the servlet
3) write the web.xml
4) compile the servlet
5) create a context - point the context to the web app structure "father"
6) install this servlet at the context
7) access the servlet
I hope this help you to understand some things, but for learning I recomended the Tomcat manual!!!! Good Luck.
