It would be a nightmare ;) Sessions are used to store objects, lots of libs does store in session various datas. All objects loaded are linked to their Classloader. So if you store a org.mycompany.MyData object under key "SOME_KEY" in session within webapp1 and you do this in webapp2:
if (session.getAttribute("SOME_KEY") instanceof org.mycompany.MyData){ // We will never get in this block because // object was created in webapp1 and we are conparing // object class to the class MyData loaded from webapp2 // unless MyData is in common/lib } If you just want to prevent user from loggin in again, use the single sign-on valve. http://tomcat.apache.org/tomcat-5.5-doc/config/host.html#Single%20Sign%20On Eoghan Shields a écrit : > Hi, > Is it possible to have a single session which can be used over > multiple applications on a single server, the basic problem is there > is multiple webapps running on the same server but when a user logs > into one, it would be nice to share all their session data so that > they could switch between applications to avoid > them having to log in again. > I have been looking at the documentation and stuff but so far have > come up blank, was hoping might be able to steer me in the right > direction. > Thanks in advance, > Eoghan > > --------------------------------------------------------------------- > To unsubscribe, e-mail: [EMAIL PROTECTED] > For additional commands, e-mail: [EMAIL PROTECTED] > --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
