Hello pavan,

thanks for reply.... but here i want to know how thesedifferent sessions communicate with each other... i mean how it knows that specific session related to specific client .... suppose for an appliation there was 10 client..... can you please tell me how a session identify's from all for the perticular client.... at different stages ( in jsp, servlet and in ejb) and these communicate....

thanks & regards
Hello friends,

As we know that "Session" is specific to client.... in any project we may use JSP's, Servlet's and EJB's .... here we are using session at different level as scope in jsp , servlet and in ejb as a stateless or statefull.... i just want to know if a client sends a request of session scope is that application maintains only one session for the entire request or it differs form jsp to servlet to ejb( please take here as statefull session) ....

If it is not means is this against rules i mean ( session is specific to client )...... can any one please clear this.....
Hello friends,

when i am reading EJB stateful session bean, came little bit confuse about how a statefull session bean will track that session bean belongs to a specific Clint.... As i think it may be using "" session using url rewriting technique ( session.encodeURL() ) .. just want to know how come it be correct.. if not can any one please tell me about this how it will track ......

Thanks & Regards

page:65 "" IN the early versions of RMI, for every stub there was a matching skeleton object. Today, though, that's not always true. ""

Have another doubt in Page:72 regarding hashmap in Dumb Questions

I am not clear about this i mean HashMap Serializablity.....

first para they given that ""Collection implementations in the J2SE API are Serializable"" and in the 3rd para said that "value()method present in the hashmap is from Collection interface".... last they ""don't rely on the Collection returned from a map's values() method to be Serializable""

may be i didn't understand properly ...... can you please explain this....
hello friends,

have one doubt when reading headfirst ejb..... she said that the latest versions of rmi doesn't create multiple skelton's for multiple clients is this true(the sentence resembles the same meaning)..... if so how it be...

can any one post your view.......

thanks & regards
