Re: transaction-problem
What sort of exception is being thrown? If it is an "Application Exception", the container is not supposed to automatically rollback the transaction (see EJB 1.1 spec, section 12.1.2 ).

Re: orion server works with jdk 1.3???
Gerald, I use JMeter (on the most horrific setting) to test Orion. I'm running RH6.2 with the Sun 1.3 jdk. With that jdk, development is fine, but when the load goes up to 20 or so simultaneous requests, it crashes almost just after the JIT kicks in. This also happens with the IBM jdk. If you have JMeter, I'd really appreciate you running it... I'd love to know what Linux-distro/jdk combinations are stable. -Dan Gerald Gutierrez wrote: It's interesting that you say that because I've been using Orion 1.3.8 with PostgreSQL 7.02 and JDK 1.3 on Mandrake Linux 7.2 for several weeks and it has not given me any problems other than those that I generate myself; I leave Orion on for several hours on end.

Re: Transaction propagation question
Yes, J2EE doesn't support nested transactions. However, a similar effect can be achieved through the suspension of existing transactions. As far as I can tell, what's supposed to happen is Transaction 1 gets suspended while Transaction 2 starts, and commits or rollsback. Then Transaction 1 resumes and commits or rollsback. Because Transaction 2 will generally throw an exception when it rollsback, Transaction 1 will also generally rollback, which results in an approximation of a nested transaction. However, this is never explicitly stated in the spec, so it would behoove you to make sure to rollback transactions yourself in your code when you must be SURE they get rolled back. Since you (Aziz) defined the SQL Delete statement, it doesn't necessarity have to be rolled back if some other transaction rolled back. I say "doesn't necessarily" because it really depends on the order and way in which you are doing things. However, you might want to try adding the following code to your catch clause in the HelloBean or HashCodeBean class. code> sessionContext.setRollbackOnly(); // sessionContext is the SessionContext object that is passed to the Bean in setSessionContext and stored as a member variable as per the EJB 1.1 spec /code> Hope this helps. Anyway, transactions in Orion are still sketchy at best... -Dan "Juan Lorandi (Chile)" wrote: I think it defaults to NotSupported; also have in mind that J2EE only allows flat transactions, so, if you a a secuence Required ---> Requires New T1 T2 it will perform 2 transactions, not connected between each other, that is, if T2 fails, T1 doesn't fail autoamtically. -Original Message- From: Aziz Sharif [mailto:[EMAIL PROTECTED]] Sent: Viernes, 03 de Noviembre de 2000 18:11 To: Orion-Interest Subject: Transaction propagation question I have a question regarding transaction propagation. I took the orion primer example and modified it so that the servlet calls Hello and then the Hello Bean calls A HashCoder bean. Both Hello and HashCoder beans are stateless session beans and perform SQL. The Hello does a delete and the HashCoder an incorrect select (causing a SQLException). I was expection these two operations to happen in the same transaction, so that the SQLException would cause the delete to automatically rollback since for both these beans I specified Container managed transaction. But it did actually delete the row. So it seems they two methods were running in different transactions. The only thing I did not do is to specify the tranaction attribute to the bean's methods to be Required or anything else. I don't know what it defaults to in orion. I am using DB2 v. 6.1 as the Database, the in both beans I acquire the connection through JNDI DataSource.

Re: sessions, inheritance and authorization
I would have to admit that the weak support for inheritence in EJB 1.1 is definately a big problem. What you generally have to do is create parallel class hierarchies: one for the EJBObject interfaces, and one for the SessionBean/EntityBean classes. Both allow normal Java inheritence. Then, map the EJBObjects to the appropriate SessionBean classes in the Deployment Descriptor, and you have created a sort of inheritence. The problem with EJB inheritence is really in the EJBHome objects. You generally have to create distinct EJBHomes for every Bean, and as far as I can see, its not a good idea for one EJBHome to inherit from another. The problem is in the create() methods. In your case, SessionManagerHome's create() method returns a SessionManager. However, if you create a PatientSessionManagerHome that extends SessionManagerHome, you can't have the create() method return something different without a different set of args (this problem with method overriding for factory methods is generally avoided in conventional Java by the use of constructors, which are NEVER inherited). If you make a different set of args, then you're still left with a create() method that returns an obect which is NOT the EJBObject for PatientSessionManagerHome, and most containers will not know how to implement it. So basically, the inheritence method I suggested above is really a kluge. There is no good solution for create methods, but one possiblity for EntityBean finder methods is to really take advantage of the ambiguity of Collection and Enumeration return values in finder methods. Have all of your finders return Collection of Enumeration, and you get around the problem of different return values in the subclass's method. However, this won't work for findByPrimaryKey(), which MUST return a distint instance of the EJBObject interface. Also, its a generally ugly solution for many OO reasons (type security, and you're essentially narrowing the scope of allowable return values). Anyway, this is all just my opinion. I'd love to hear it if anyone has figured something out that has escaped me. -Dan Adam Winter wrote: Thanks for your reply.

Out of curiosity, why do you want to do >this? In our web-based application all users see a common log-on screen, and after their authentication, based on their user role, we redirect them to the appropriate user interface. To represent that I envisioned having a "SessionManager" Statefull Session bean, which would govern what was possible based on that user's role. It would encapsulate other entity beans, representing the other people and application objects that the logged in user is allowed to participate with. In accordance with what I think is good OO designed, I pictured having "SessionManager" as abstract, and deriving sub-classes based on user roles. In the case of my domain, health care, there might be a PatientSessionManager, a PhycisianSessionManager, and ClericalSessionManager. By doing this I can store the commonality (of which there are a few) in the super class. I think the case for inheritance amongst business logic is pretty strong. -adamw -- Daniel G.
