Hi,
Is this right?
In Java API, I found some useful information.
"There is one context per "web application" per Java Virtual Machine. (A "web
application" is a collection of servlets and content installed under a specific subset
of the server's URL namespace such as /catalog and possibly installed via a .war
file.) "
I also test it with Tomcat 3.2.3.I create two webapps.one is 'test1',the other is
'test2'.In "test1", there is a javabean with "scope=application".All jsps in "test1"
can get the value of the javabean.But got nothing in "test2".
If I am wrong, please info me.
