Re: [JBoss-user] Threads and beans
JBoss *is* acting according to spec and your disappointment is unfounded. You're just confusing your session beans - and what your client stub actually represents. If you are using *stateless* session beans (SLSB), you can have as many threads share that same client stub and use it concurrently. However, that does NOT mean that the same instance of the SLSB is being used on the server side. The server is smart enough to make sure that a different bean in the container is servicing each client. A server can reuse SLSB's for the same or different clients, but *not at the same time*, and it makes sure it starts off at a fresh state before the next usage. Some containers will pool instances, some will just instantiate new ones each call. So basically, each time you call a SLSB, you are not guaranteed the same bean on the server is being used (thus the term "stateless"). Now, if you are using *stateful* session beans (SFSB), your one client stub will always point back to the same instance on the server side (thus you can save "state" in it - sort of like an HTTPSession). Each time you invoke your stub, you are guaranteed that the same instance on the server is being used (until it times out or becomes invalid for whatever reason - in which case you'll need to get a new one). You cannot share that stub with other concurrently running threads. You should probably take a closer look at the ejb spec, specifically the sections on lifecycle.

How shoulf look like "beanJndiName" property for a bean like this: * @ejb:bean * type="Stateless" * name="QueryEngine" * jndi-name="ejb/QueryEngineRemoteHome" * local-jndi-name="ejb/QueryEngineLocalHome" * view-type="both" * * @jboss-net:web-service * urn="query" * expose-all="true" * it produces: is it correct?

[JBoss-user] Re: [JBoss-user]Invalid service.xml file (was (no subject)
Hi Karl.
There were only two instances that I had this error occur.
1) Incorrect syntax in my oracle-service.xml file (you did name this
oracle-service.xml, right? JBoss sometimes does weird behaviour if you don't name
these files something-service.xml).
2) (More frequent) The username/password you specify for Oracle don't match a valid
User/Password for the Oracle Database. (Use something like SQLPlus and see if you can
login using webapp/webappprod
as you User/Password.
