Title: RE: How to use EJB2.0 on Orion Hi Heinz. Your are correct. The update of the ATM to EJB 2.0 left some unwanted remains. It will be updated. WR -Original Message- From: Haeussler, Heinz [mailto:[EMAIL PROTECTED]] Sent: den 25 september 2000 07:59 To: Orion-Interest Subject: AW: How to use EJB2.0 on Orion Hello Magnus, i studied this ATM-example and compared it with the ejb-2.0-specification. I don't understand the dependent-class LogEntry: Is it a dependent object class or a dependent value class ? 9.4.3 of the spec tells us for a dependent object class: - can be the value of a cmr-field - cannot be the value of a cmp-field - must not be serializable a dependent value class: - can be the value of a cmp-field - cannot be the value of a cmr-field - mus bei serializable In the ATM-example, the LogEntry-Class is serializable and a Collection of LogEntries is a cmp-fields as well as a cmr-field. In my opinion a cmp-field cannot be a cmr-field. Tell me if i am wrong.

The ATM has been running EJB 2.0 since the night it was implemented in Orion, I just thought I should do an effort to document the application before putting it up there for public access. Anyway, as previously said, its now available at http://www.orionserver.com/orion/applications/atm.ear http://www.orionserver.com/orion/applications/atm.ear Please notice that it will change over time, whenever a new part of EJB 2.0 or Servlet 2.3 is implemented.

well, maybe there IS no avail. Not many of us have done EJB 2.0 yet, and as far as the orion core team goes, I hope (!!) they are busy writing documentation for the basic stuff (and improving orion in their spare time). actually, I was trying to refer to documentation that covers the basic orion-specific items that one runs across when first installing and running it. I dont think we need EJB 2.0 doc from orion that badly. And I think it is perfectly OK to require a thorough knowledge of the specs on the side of us developers..
RE: How to use EJB2.0 on Orion
Doesn't the use of the Address dependent object in the Person remote interface violate section 9.4.11 of the EJB2.0 spec? Specifically: - The Bean Provider must not expose the dependent object classes or the persistent Collection classes that are used in container managed relationships through the remote interface of the bean. This means that the get and set methods of the entity bean's abstract persistence schema must not be exposed through the remote interface of the entity bean except in the following cases: * When the relationship is defined as a one-to-one or many-to-one relationship between two entity beans. * When the get and set accessor methods are methods for a cmp-field. Set accessor methods cor-responding to primary key fields, however, should not be exposed in the remote interface of the bean. - and... - Although dependent object classes cannot be exposed in the remote interface, the Bean Provider can use the accessor methods to obtain instances of these persistent classes (including the collection classes that correspond to relationships), and can copy data to or from these instances to instances of the classes that are exposed in the remote interface. - Unless I'm mistaken (no way, never happens :-), you need to copy the Address data to a detail object before returning it.

Re: How to use EJB2.0 on Orion
Perhaps the EJB 2.0 spec on javasoft would be a place to start. The whole thing is quite long, but Chapter 9 explains the new persistence mechanism, and that's probably all you need. The main differences (but by no means all the differences) are: 1) you need to specify the appropriate dtd at the top of the ejb-jar.xml, so that the first few lines look like: ?xml version="1.0"? !DOCTYPE application PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.2//EN" "http://java.sun.com/j2ee/dtds/ejb-jar_2_0.dtd" 2) the "bean" class is abstract, and has pairs of abstract get/set methods instead of data fields for the persistent fields.

Re: How to use EJB2.0 on Orion
I have been sending this mail for quite some time but to no avail. well, maybe there IS no avail. Not many of us have done EJB 2.0 yet, and as far as the orion core team goes, I hope (!!) they are busy writing documentation for the basic stuff (and improving orion in their spare time). regards

Thanks a lot Nick. Can you also send me a sample code or whatever and moreoever, have you yourself been able to get this stuff working on Orion? Vimal --- Nick Newman [EMAIL PROTECTED] wrote: Perhaps the EJB 2.0 spec on javasoft would be a place to start. The whole thing is quite long, but Chapter 9 explains the new persistence mechanism, and that's probably all you need. The main differences (but by no means all the differences) are: 1) you need to specify the appropriate dtd at the top of the ejb-jar.xml, so that the first few lines look like: ?xml version="1.0"? !DOCTYPE application PUBLIC "-//Sun Microsystems, Inc.//DTD J2EE Application 1.2//EN" "http://java.sun.com/j2ee/dtds/ejb-jar_2_0.dtd" 2) the "bean" class is abstract, and has pairs of abstract get/set methods instead of data fields for the persistent fields.

Re: How to use EJB2.0 on Orion
Don't forget that EJB 2.0 isn't a standard yet. It's a draft. Personally, I'm mucking about with it a bit, and the parts I'm most interested in - the OR mapping - I've not really covered, so I'm in the same boat of wanting more information, but let's be real about it. It's not there unless we generate it ourselves; we can't expect the Orion team to do everything for us (we *are* developers, right?) so instead of griping about it, read the draft. Play with it. Try things out. Tell others about it, so we can ALL learn. (If I see stuff on it that I think is useful, as soon as the infrastructure is done for the new orionsupport, I'll put it online.)

Re: How to use EJB2.0 on Orion
I gather the ATM EJB 2.0 app is out now - but perhaps a very simple app will still be useful. See attached. The only problem I have had with EJB 2.0 in Orion is trying to do a 1-1 mapping to a dependent class. Nick At 12:43 PM 9/20/00 -0700, you wrote: Thanks a lot Nick.

RE: How to use EJB2.0 on Orion
Hi, have the same problem as nick. When i have an 1-1 relationship to a dependent orion throws errors which arise due to the following. (1) it creates its own dependent classes which should be concrete implementations but they are also abstract so throws error when returning objects ( this is new problem in 1.3.8, 1.3.6 did not have this trouble. (2) internally it tries to assign the the dependent class created by orion to the dependent class and throws classcastexception i dont know whether this is a bug or a problem with mine. anybody has any idea? plus can someone tell me how to refer to beans deployed in another ejb-jar file in relationships? thanks much, Krishnan -Original Message- From: Vimal Kansal [mailto:[EMAIL PROTECTED]] Sent: Wednesday, September 20, 2000 4:04 PM To: Orion-Interest Subject: Re: How to use EJB2.0 on Orion EVen if you specify the multiplicity other than 1? vimal --- Nick Newman [EMAIL PROTECTED] wrote: I gather the ATM EJB 2.0 app is out now - but perhaps a very simple app will still be useful.

Re: How to use EJB2.0 on Orion
Yeah, I know - and the example apps are good, but they're more than I'd like. (Incidentally, the ATM has been EJB 2.0 for a while now.) I like Ernst de Haan's approach - he covers one area and tries not to dress it too much. "Here I'll cover creating a simple app." "Here I'll create a CMP bean and use it." The ATM is good, but it does *everything* - which makes learning individual elements more difficult than it could be if you had, for example, an OR-mapping application or a security model application.
