[JBoss-user] [EJB 3.0] - Re: Re-obtaining a reference to an existing stateful EJB3 in
It appears to work fine for me :-) and I successfully call business methods after deserialization. I have not tested it over a long session containing numerous calls and also not across different VM's for clustering. Let me know how it works for you?

[JBoss-user] [EJB 3.0] - Re: Re-obtaining a reference to an existing stateful EJB3 in
1. Does JNDI not serialize the references? I will try this out when I have a moment. 2. I have found that ejb2.1's can do this. From the home interface one can call getHandle(). This handle is serializable and can be used from different VM's. Do a search for getHandle() in these forums. I have also found that there is a compatibility layer for ejb3's to behave like ejb2.1's. In this case a home interface must be defined and the getHandle() function is available. I don't know if it throws unimplemented exceptions but there is test code that uses it. I don't have the test class names handy, but do a search for getHandle() in the cvs code in the ejb3 directory. I wouldn't want to use this though as I might as well use ejb2.1's then.

[JBoss-user] [EJB 3.0] - Re: Re-obtaining a reference to an existing stateful EJB3 in
Thanks for the suggestion. Can JNDI efficiently handle thousands of session objects like mine? I was thinking along the lines of a database and storing the serialized handle to the ejb. I also don't know if one can just store the reference to the ejb and get access to the ejb instance from another clustered server. I saw some ejb2.1 sample code where one can get a hold of a handle to the ejb from its home interface - getHandle(). This handle is apparently clusterable and serializable. Can one get a similar type of handle from a ejb3?

[JBoss-user] [Management, JMX/JBoss] - Re: How do I get a reference to the WorkManager from a MBean
Thanks for the tip. I have created a new ThreadPool of my own and all seems to work well. Please forgive the newbie question, but how do I obtain a reference to the jboss-service created system ThreadPool from my MBean?

[JBoss-user] [EJB 3.0] - Re-obtaining a reference to an existing stateful EJB3 instan
Hi, I have a proprietary communications protocol where clients come in over TCP sockets. I then create a stateful EJB3 per client. If my socket connection fails I would like to reattach the client back to the existing stateful EJB3 instance using a sessionid of sorts. Does anyone know how I can re-obtain the reference to the existing stateful EJB3? The system eventually needs to be clustered and hence the client might reconnect to a socket on one server and the stateful EJB instance is on another server. Thanks for the help.
