What about using JNDI to share objects between webapps?
I think that:
init(){
...
String context = "java:comp/env/xxxx";
InitialContext ic = new InitialContext();
ClassX c = (ClassX) ic.lookup(sContexto);
...
}
should return the same object to different servlets/webapps, if you define
the jndi-resource globally, i.e., in conf/server.xml

Subject: RE: ClassCastException while sharing objects accross applications
The type in Java is a combination of a fully qualified class name and its
defining classloader. So the two objects with the same class name are
considered different types in your two web applications because each web
application is loaded by the dedicated webapp classloader.
To solve your problem you can use object serialization or if your objects
are the java beans you can use the java.beans encoding.
"The XMLEncoder class is a complementary alternative to the
ObjectOutputStream and can used to generate a textual representation of a
JavaBean in the same way that the ObjectOutputStream can be used to create
binary representation of Serializable objects. "

Subject: ClassCastException while sharing objects accross applications
Hi,
I am trying to share an object between 2 applications deployed on the same
tomcat server. I have put the object in the ServletContext in my first
application. I access the object using
ServletContext.getContext("firstApp").getAttribute("object");.
The object comes in fine but it won't let me cast it to the actual Object
Type. I get a ClassCastException. I tried printing the name of the class.
That also came fine (same class name).
Thanks in advance.
