Create an object that's shared with multiple applications?
Hello,
I currently have a JSP application under Tomcat that uses an object
created when Tomcat starts up. The object is created using a class
that implements ServletContextListener and I can call the object from
my JSPs. All is well.
Originally, I thought I could have one of these objects per
application. But it turns out I can have only one per server.
I've been doing some searching and looking through the documentation,
but I can't figure out how to do this.
How can I create a single object when Tomcat starts up and access that
object from multiple web apps?
Thanks,
Matt

I did, but then I get more than I get one object created for each application.
I literally just stumbled a mention of a "crossContext" setting in
Tomcat, but I'm still trying to figure out if that will help here.

Have you added listener and listener-class tags in each applications'
web.xml?

You can serialize/deseriaize your object(s) in /from an Ms SQLserver blob
field
I can email you some code off list if this is what you are looking forward

Pid,
I'm sure this is a stupid question but...what? I don't follow.
I can store the object in a database? I'm limited to SQL Server.
Does that matter?
