Re: Sessions and W98 + IE
Hi David. The major errors I have come accross in IE (all tested version of 4, 5, 6) was that the 56bit encryption package was completely broken in IE.

Re: distribute beans in different jars
Matthias Gottschlich wrote: Hi, i am new in development of j2ee-applications, so i think my question could be too stupid.. We have 70 entity-beans with local and remote interfaces and 5 session beans (will be more in future) in one ejb-jar-file. The session-beans reference the entity beans with local interfaces! The entity-beans are very stable ( because we are developing the session beans now). The ejb-jar-file resides in addition with an client.jar-file in on ear-file. The deployment time is very long ( a few minutes ). I think the time is very long, because orion test the entity-beans on changes (which never occure in the moment). Is there any way to speed up the deployment time? Could we divide the entity-beans and the session-beans in two different jar, to speed up? (i think the local references could be a problem) best regards Matthias Gottschlich mail: [EMAIL PROTECTED] Hi Matthias. Yes. I currently have 96 EJBs (mostly SLSBs) split up between 12 jars. They can call one another from different jar files w/o a problem. I have all the jars in a single Ear file.

Re: Caching Group Information
Christian, Joanne wrote: Hi All, I am using a custom user manager that gets group and user information from the database. I would like to cache the database information when the user manager is initialized; and access the cache to get the user information. Can anyone suggest the best method for doing this? I am thinking about using a hashmap, but I'm not quite sure what is the best option. Thanks, Joanne Hi Joanne. I am using an Entity EJB, and letting the Container worry about how to handle the cache. My UserEJB actually loads itself from several tables, and has two hashmaps and some rather complex objects. Of course, this has to be done using BeanManaged Persistance, but actually works quite smoothly. Among other things, this is key to how the security model for my application works. In the EJB specs, there is a method called getHandle(), which returns a small, serializable object, that can be passed around and/or stored in Hashmaps or other objects. It can be used to obtain a remote interface to a specific EJB w/o having to do a home lookup and a findByXXX call. (userHandle.getEJBObject does the trick). With this method, if the EJB is being used, container keeps it around. If/when not being used, container releases it (supposedly). And as this is handled by the container, you do not have to write the code to load/release the user data. And this method is also expandable into a cluster (only one instance of Entity EJB per cluster, + backup copies, with cluster worrying about how to keep data syncronized, not you). -Steve -- Stephen Davidson Java Consultant Delphi Consultants, LLC http://www.delphis.com Phone: 214-696-6224 x208

Since I am doing the deployments remotely, just sending one file over has been proving easier and faster for me than trying to send the individual files over. The only time that I have had difficulties is when the API's for the EJB's are changed, or EJB's are added or deleted. -Steve -- Stephen Davidson Java Consultant Delphi Consultants, LLC http://www.delphis.com Phone: 214-696-6224 x208

Re: Simple question re caching/pooling of BMP Entity Beans
Hi Guys. Having just finished solving some headaches on this topic, my comment is, what are you guys doing differently from me? One of our ex-guys was nice enough to write a mess of code to update data that an entity EJB used/stored, but rather than updating the EJB, the database was updated directly. Since the EJB (BMP) was being cached, not loaded, and had a verrry long time out (intentional), this was producing some really nasty bugs. To get the data to load, we had to stop and restart the server. And I can very that findByPrimaryKey was most definately getting called. One thing I did notice, from very early in the project. Left to its defaults, the timeout on an Entity EJB in Orion is very short. It may be unloaded between consecutive calls. For example, the following block of code did result in three calls of ejbLoad on the entity EJB until we reset the time-out. UserHome userHome = getUserHome(); //Returns home interface to UserEntityEJB User user = userHome.findByPrimayKey(username); //Returns Remote Interface to Entity EJB user.login(password); UserData data = user.getData(); I forget where off hand to set the EJB Time-out, but I think it was either the ejb-jar.xml, or the orion-ejb-jar.xml file. If you need, I can look it up and let you know. -Steve Geoff Soutter wrote: Hi Sergey, Thanks for the reply. I didn't explain it very clearly did I?

Re: Migrating From Websphere to Orion
Greetings, Herman I recently parted a rather large application from Weblogic to Orion (not the same thing, I know, but some of the issues will be the same). I have not had a problem with Orion and the EJB 1.x specs. Once I had the application-specific xml descriptors worked out, and some minor EJB issues, I have not had any problems with the EJBs. I will be trying clustering EJB's next starting next week, something that is not particularly well documented at the moment. Something that I have noticed that the bigger Platform Providers are doing that Orion is not is trying to provide all the features for everybody. Orion seems to limit themselves a little bit to what most people need, and then allow for add-ons after. The only issues I ran into where the following; - The Weblogic specific drivers for Oracle did not port (gee whiz, I wonder why!). I had to find and load Oracle's JDBC jar files. - There seems to be an issue with Orion's classloader and library jars in the Ear file (possibly fixed in this last release, I have not had a chance to experiment yet) - Orion is MUCH more strict about imports in JSP's then Weblogic. By default, Weblogic imports just about everything into a JSP for you. With Orion, you need to specify what classes your JSP's are using. (NOTE: Weblogic is actually drifting from the spec in this case, Orion is following it more closely). - Configuring Orion had a sharp learning curve, and at the time not everything was as well documented as it could have been. The last two months Orion has been releasing upgraded documentation, with more to come. -Steve -- Stephen Davidson Java Consultant Delphi Consultants, LLC http://www.delphis.com Phone: 214-696-6224 x208
Re: Multiple data sources for each application
Hi Atul. Sorry, no I do not know, although I suspect so. We are using BMP Enity Beans, due to the unusual database design (CMP won't handle it). However, our BMP EJB's do automatically deploy, and successfully create and register their own connection pools in JNDI on demand. Otherwise, our entire security and database access framework would be non-functional. You would have to look up the exact sequence of events, but there are a number of function calls made on the EJB during load and activation before any attempt is made to access the database. The exact sequence of calls is specified in the EJB specification. If you were to intercept one of these earlier calls to create your connection, I suspect that would work. We are doing something similiar. -Steve Setlur, Atul (MED) wrote: Steve, Do you know if CMP Entity Beans deploy if the connection pool is established programatically?

Re: starting orion application server

I just start it from the command line; c:\orionjava -server -Xincgc -jar orion.jar Note: Depending on which JVM you are running, you may need to change the -server to -hotspot.

And as I am running on Linux, I am not sure how effective it would be for you anyways. I had one person here spell the directory wrong, and it took a little before it was figured out what the problem was. A wild guess, are there any other web servers running on your machine?

Re: Orion-Interest subscription notification
Hi Yilmaz. You are obviously new here, or you would know that you do not need to threaten in order to get help. On the topic of the persitance directory, there is an issue where this directory is not created automatically under WinNT/Win2K. So you have to create it manually yourself. You do NOT need to put the orion directory into your classpath. The following command issued in the orion directory should fix your issue with the transaction.state file. C:\orionmkdir persistance I know about this because one of the developers on my team ran into this issue yesterday when setting up Orion on his Win2K box. If you have not done so already, you also need to copy the tools.jar file from your jdk directory into your c:\orion directory. FYI, our testing has indicated that orion works best on Bea's JDK, Sun's JDK, or IBM's Hotspot JDK. On Microsoft's JVM, we sometimes get for no apparent reason some rather funky errors that go away when we switch JVM's.

Re: Sessions Problems...........
That would be the place to start. Unlike C/C++ where the keyword static denotes a private variable, a static variable in Java is shared among all instances of the class. This includes instances of subclasses. So if one instance of a class changes the value of a static variable, all the other instances immediately see the new value. If you are storing login information in static variables, this would cause this data to be shared among all instances, with last one to set the variables winning. -Steve PS. Like your sig!

Re: Listening on a JMS Queue on another machine throws exception
Hi Kesav.
Something really weird is going on here. When I try to start the
listener locally, if fails to connect with a JMS Exception.
I included the help section for my listener class, so you
can see what some of the command line options are about.
The Orion switch also tells the listener that it needs to do
a qreceiver.receive() when listening.
When the listener tries to close the connection, the host
throws a null pointer exception, as well as an exception
occuring on the listener.
Suggestions?

Re: questions on legacy transaction support
Hi Reason. I was hoping somebody on the list would respond sooner with known reliable information. I would suggest (b). I am doing distributed transactions over (potentially) multiple servers using multiple EJBs. This seems to be working for me (initial tests are ok). However, the code is in Alpha release, and has not seen serious stress levels, or been placed in production. So I can't verify yet how well this will work once thousands of users start hitting it. Good Luck, Steve Reason wrote: I'm attempting to use Orion pretty much for the easy custom authentication/user management and very little else. That all works pretty well -- as an ex-JBoss user, let me say that I like the straightforward approach. So I have a bunch of BMP beans that wrap some legacy software. The legacy software comes complete with legacy transactions and I'm trying to figure out the best way to deal with this such that: 1) I can reliably pick up the right legacy transaction at the right time in my bean methods 2) a given user can have more than one transaction on the go at once in separate threads Now, I can write any old middle layer I choose to associate specific legacy transactions with some object/value/concept from the EJB layer (in a hashtable, for example), but I don't have a good enough grasp on the Orion container to figure out which of the following items are going to be constants between different threads or method calls to the server: a) EJBContext (EntityContext, SessionContext): these would seem to be out of consideration, as they are reused between beans and threads, and a transaction might extend throughout several method calls in both session and entity beans. b) UserTransaction: I could associate a UserTransaction instance with a legacy transaction instance. If I start a transaction in a session bean, which then calls entity bean methods, is the same UserTransaction instance going to result from calls to context.getUserTransaction() in the contexts for the various beans? c) Principal name: I could associate a legacy transaction with a principal name if not for wanting to allow each principal the option of multiple concurrent transactions in different threads. d) Thread: a legacy transaction could be associated with a specific server thread. Is this going to work? Are UserTransactions associated with a specific thread throughout their lifetime? Is this thread the same thread that is used for separate method calls that fall within the transaction? So, any suggestions or ideas from the list on this one?

Clusters, JMS, and standalone applications
Greetings. I am having difficulty with getting JMS working under Orion in a clustered environment. The general layout of the cluster is this, 1 (or more) Util machines, one of which is running the JMS server. -Run high-load utility programs that are listening on various Queues for new jobs (basically offline batch processes) 1 Load Balancer machine 2 (or more) Web/App Servers. Some applications will send messages to the Queues for execution offline by the listening utility programs. Initially when I tried to set this up, I tried to have the applications log into Queues in the cluster. This threw all kinds of weird exceptions, and also looked like I would have to have one instance of each utility program per running instance of Orion. So I tried moving all the Queues to the Utility server, and running the Utility programs from there. I set the jms.xml file (attached) to the IP address of the Util box. Unfortunately, the util apps are STILL not getting messages (which are sent by EJB's). No errors are getting thrown, so I suspect that the messages are being put on the local queues. If anyone has any examples of how to set this up, it would be greatly appreciated.

Re: Problems accessing remote EJBs
Greetings, Kesav. I have had to chase down a few instances of this myself. A useful tool I found was the orionconsole.jar. It is still alpha, with lots of missing functionality, but one thing that is working is the ability to read Orion's JNDI tree. A little hunting should tell you what the name is and where your ejb is registered. I found that unless everything is perfectly specified in the XML files, Orion has a tendency to auto-generate JNDI names that may not be what your code is looking for. This would be one way to verify what is going on. -Steve Klaus Thiele wrote: Hi Kesav, thanks for help, but it does not work (1.5.2 and 1.0.2.2.1) klaus Am Donnerstag, 20.

Re: Transaction question ?
Eddie wrote: Hellu, Please some help on the following transaction scenario ?: I am receing some information through a HTTP post method. The servlet, running as part of a J2EE application, calls a EJB method A. The EJB method does some little processing. After this, it checks some conditions, and might do some more processing in an other EJB method B depending on the conditions (in the same method still). I want to call method B in a thread, such that the client, performing the HTTP request, isn't waiting too long. So I want to start method B in a thread, such that the initial EJB method A returns. How does the transacion model looks like in this case and it is wise to do it like this ? (My transaction attribute is set to Required and I am using CMP). I mean, is EJB method B, that runs in the thread executed in a new transaction, as the initial EJB method A returns, or does it run in the same db transaction as method A ? Eddie Hi Eddie. Launching threads in an EJB is against spec, as you may have noticed. What you may want to consider is using JMS. You would want to set up the EJB as a MessageDrivenBean, and then have the onMessage call method B.

Yesterday in just a few hours this virus caused panic in New York, according to news broadcast by CNN. This alert was received by an employee of Microsoft itself. So don't open any mails with subject: A Virtual Card for You. As soon as you get the mail, delete it. Please pass this mail to all of your friends. Forward this to everyone in your address book. I would rather receive this 25 times than not at all. Also: Intel announced that a new and very destructive virus was discovered recently. If you receive an email called An Internet Flower For You, do not open it. Delete it right away! This virus removes all dynamic link libraries (.dll files) from your computer. Your computer will not be able to boot up !! -- Stephen Davidson Java Consultant Delphi Consultants, LLC http://www.delphis.com Phone: 214-696-6224 x208
