sorry about previous partial post ... I'm running 1.4.4 on Windoze 2000, and have an app composed of 2 ejb modules, 1 web module and 1 application client.

Globally available environment vars
We're getting to the point where we're integrating a bunch of stuff into a web app .. two different ejb modules plus a web module. I'd like to have a single central place where user-customizable configuration can be stored. Experimenting with env-entry in the web.xml file seems to indicate that those environment vars are not available (by any naming convention I've been able to think up) in the ejb modules. I can put the env-entry into the deployment descriptor for the bean that needs the value and get access, but that would be too messy for the end-user to be messing with! Anyone have any ideas?

Orion
Hello
all,
My
developershave been fighting with the JMS implentation in Orion so I
decided to play around with getting one of the open source JMS implentation to
work with Orion. At the bottom of this email are the steps to get
OpenJMS working and the changes you need to make to your applications to use
it.
I havn't been able
to test it too much, but in our limited tests everything seems to work.
So far, all of the problems that we were having with Orion's JMS
implementation have gone away so this at least meets our short term needs
until Orion's JMS is working (hopefully soon)...
Regards,
Jon
Lipsky
Using OpenJMS with
Orion
1. Download
OpenJMS from http://www.openjms.org
2. Extract the
OpenJMS archive on your machine and follow the intructions for building
OpenJMS. (execute the command "build
all")
3. Copy the
following files to your /lib directory your Orion
installation:
${OPENJMS_HOME}/dist/openjms-0.5.jar
${OPENJMS_HOME}/dist/openjms-client-0.5.jar
${OPENJMS_HOME}/dist/openjms-rmi-0.5.jar
${OPENJMS_HOME}/lib/log4j.jar
${OPENJMS_HOME}/lib/exolabcore-0.1.jar
${OPENJMS_HOME}/lib/jakarta-regexp-1.1.jar
${OPENJMS_HOME}/lib/tyrex-0.9.6.1.jar
4. Start the
OpenJMS server(execute the command "admin -config valid_jms.xml",
and then use the menu item "Start OpenJMSServer")
5. Create any
Queue's or Topic's you want to use in your application using the admin
application.
6. Modify your
applications to use a different context factory to when they create their JMS
connection factories:
Hashtable
props = new Hashtable();props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.exolab.jms.jndi.rmi.RmiJndiInitialContextFactory");Context
context = new InitialContext(props);
7. By default the
Queue connection factory can be found at the JNDI name
"JmsQueueConnectionFactory", so your may need to change your
application or the change the JNDI location used by
OpenJMS:
QueueConnectionFactory _factory =
(QueueConnectionFactory)context.lookup("JmsQueueConnectionFactory");
RE: Stateless session beans reuse

Large Collections
We're working on an ecommerce site which has a rather large ( 3M) record products table. We were hoping that the Collection which is returned when an entity bean's collection field getter is called would be smart .. that the entity beans would be instantiated as needed vs all instantiated at once. Alas, it appears that this is not the case. I initially ran out of memory trying to get the collection until I applied the ApplicationAdministrator.flushEJBCache hack, but the elapsed time is still just too large when dealing with that collection. My question is how are people handling this kind of problem? Should I just abandon CMP for this stuff and do it in a traditional fashion, perhaps a temporary table, via JDBC? Maybe cache the handles from the CMP collections for reuse? Go for a database specific solution? tia john d

RE: can client see dependent objects (ejb2) ?
I believe you must use a Dependent Value class to get dependent objects .. the idea with dependents is that they are tightly associated with an entity, and the entity should use them and expose in it's own interface .. see the ejb spec 9.3.1 on granularity, and dependent objects and value objects in 9.7.x jd -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Tim Drury Sent: Thursday, October 26, 2000 1:05 PM To: Orion-Interest Subject: can client see dependent objects (ejb2) ? I save successfully saved an ejb w/ dependent object into the database. But when I try to pull the ejb back (w/dependent object), the client throws an exception saying it cannot find the dependent object class. Client code snippet: system.out.println(contact.getName()); // this works Address a = contact.getAddress(); // this throws exception The ejb attributes print out on the screen fine, but when I try to get the Address dependent object the *client* throws this exception: java.lang.ClassNotFoundException: Address_Dependent0 Now, I think the problem is obvious. My class is called "Address" and Orion compiled the class on the server and called it "Address_Dependent0". Obviously, the client isn't going to see that. My question: Can the client not see dependent objects at all? Should I write another Address class and copy all the dependent Address class attributes into it? Is this addressed in the spec (I didn't see it)? I hope this is how it is supposed to work, I sure hope they change it - it seems a huge waste of time to have to write 2 classes for each dependent object. -tim

As I mentioned in an earlier message, I have some working example code that has an EJB 2.0 CMP entity bean working with both one-to-one and one-to-many unidirectional relationships. Next, I want to change the one-to-many relationship to be bidirectional. I expected this to be a simple change, but it didn't work out that way. I see that the ATM example does not include a dependent object with a bidirectional relationship, so I'm wondering if thie feature is known to work or not. If no one here has used this feature successfully, I'll add a bug report to bugzilla, but I wanted to make sure I did everything right first. To make my changes, I added abstract set/get methods to the dependent object class (EmailDO.java)for the remote interface of the EB it should refer to (Person.java). I also modified the deployment descriptor to have a CMR field in the dependent relationship section and a CMP field in the dependent section. I realize that the presence of the CMP-FIELD tag violates the spec, but Orion will not deploy dependent objects without it (it complaines that it can't instansiate an abstract class that it had generated). It all now looks like the Order-Lineitem example in the PD1 spec. After Orion deployed the app, I ran it and looked at the database. Orion had correctly created a table to hold the dependent (since its a many it needs its own table), but the field for the Person EB remote interface (which is the EB that the dependent is created by and should refer to) was named VALUEPERSON and had null as its value. This seems to indicate that Orion is not understanding that this field is supposed to be a CMR field. I reviewed the spec and there is no requirement that I manually set the Person remote interface in the dependent object, but I doubt thats the problem anyhow, since Orion named the person field "valueperson", indicating it thinks person is just another CMP field. Anyhow, I think I did everything right and I posted the code below. If someone sees something wrong or has any suggestions as to what I should try, I would appreciate you correcting me.

Unfortunately, it dosn't really help here .. if I use a message-driven bean, then *it* will have to do the callback to the client code (which likely will not work in the same fashion) .. and the client itself can't be a message bean because you can't have regular 'session bean' type methods on it .. only the message handling stuff. jd -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Juan Lorandi (Chile) Sent: Friday, October 20, 2000 5:54 PM To: Orion-Interest Subject: RE: Remote object callback from a session bean Message Beans, regretably, they're only a public draft at this moment, tough orion already provides some support for them -Original Message- From: John D'Ausilio [mailto:[EMAIL PROTECTED]] Sent: Viernes, 20 de Octubre de 2000 17:22 To: Orion-Interest Subject: Remote object callback from a session bean Tell me if I'm insane or not ... I have a session bean, and one of the services it provides is a long-running process which needs to inform the object on whose behalf it is running when various events occur. 1. Client gets the session bean and calls createProcess(processID, this) ... passing itself along 2. Session bean does it's thing, create a process and gives it the client object reference 3. As the process processes, at various points it calls receiveEvent() on the client object reference Seems to me that this should be feasible using standard RMI stuff .. I made an interface extending Remote that exposes the receiveEvent call, made the client class extend UnicastRemoteObject, and ran rmic on the class to generate a stub. The stub source looks sensible. Everything actually runs without error, but the client callback never gets executed and the client finishes but never terminates, as there are a couple of RMI-related threads that never die.
