Hi,
1)I'm using weblogic 7.0 for my web application.
How can I upload a jar file to my web application without
shutting down the so that subsequent requests use the classes from the new jar.
2) If 1) is possible, can I overwrite an existing jar with a new version of the same at runtime without bringing down the site. In this case, what happens if there is a class in the new version which is incompatible with the older version (say a member variable is removed) and
there are objects of this class around when I upload the new version of the jar.
