Rather than ask for "All the ways" (very short question requiring a very long answer), why not explain, in some detail, what it is that you're trying to do.
Then, maybe someone will suggest the best strategy for your situation.

If you're not familiar with the various 'scope' objects made available by the servlet spec, I recommend that you download the spec and give it a read.
There is a link in my signature.

To share data in the same application its good use Java beans.

To share data in the different applications you can use the servletContext.
But few containers like Tomcat will restrict from you from doing this.
You can use DB to share the data, but which is constly interms of time.
I suggest you to use XML to share the data.

Web applications do not share a ServletContext even if they are running in the same JVM.

One way to share data is with a JavaBean and the HttpSession. That's pretty much basic JSP and Servlet development. I've got a set of free tutorials and sample code/war files that demonstrate how to use the HttpSession, and share a JavaBean between a Servlet and a JSP:
