Question

I am interested to ask… Is it possible to keep session between TWO war(s) on ONE web server.
For example there are

• A) war file A

• B) war file B

  war file A has

…

String aText="Hello World";
session.setAttribute("anAttribute",aText);

…

so my question is… Can I call code like a

String fromAWarFile=session.getAttribute("anAttribute");

… from war file B to get “Hello World” value of war file A?

Any useful comment is appreciated

I think what you are looking for is session clustering http://www.ibm.com/developerworks/java/library/j-jtp07294/index.html, I think all the major servlet containers support this.

Here is the documentation from tomcat http://tomcat.apache.org/tomcat-6.0-doc/cluster-howto.html
