[jdjlist] RE: J2EE session bean

[Greg Nudelman]

Hmmm.... I think it is certainly possible, however, the whole point of J2EE is that you don't need to do this nitty-gritty details.  Instead you should be able to use the admin utility or xml config files to set up how many session beans you want in your pool.  Pool is created automatically, and to get an instance over the distributed network, you simply have to get a Home stub from context and ask it to create a remote instance of the bean you want.  The Home object will figure out if you already have some free objects in the pool, or whether to create more, etc.  You don't need to worry, the J2EE framework should take care of it:

 

        CreateXHome createXHome = (CreateXHome) context.lookup("Your App.CreateXHome");
        CreateX createX = createXHome.create();  //get from a pool, or make a new one
        createX.createX(someData); //call a remote method on a session bean

Hi,

It is possible to connect a client to a session bean SessionBeanFactory containing a pool of the overs session.

and giving this method:

private Hashmap map;

SessionBean getSession(String nameToLookup)

{

if(map.contains(nameToLookup)) return map.get(nameToLookup);

//crete new connection to the bean session using a service locator

map.put(nameToLookup,mynewsession)

return mynewsession;

}

Regards.
