Re: Synchronized session bean?
El Jeffo ([EMAIL PROTECTED]) wrote: Hi everyone... I thought there was a way to synchonize a session bean such that I suppose you could say that only one user or servlet could use it at a time. Simply put if there's $5 left in the bank, you wouldn't want to have a user withdraw $5 with two different web browsers if they hit submit at the same time... so we kinda want it to be like there's only one teller window, and the servlets have to wait their turn. How to do it kinda escapes me, but let me know if there was something I missed. It would be most appreciated. No need to write volumes of code if you know of a good web site reference for example. Just sent the URL, I'll do the reading from there. Jeff Access to each session bean instance is serialized, but the spec doesn't specifically allow you to say there may only be one instance of a particular session bean class. Access to entity beans is also serialized and you can be certain that, in a a given app server instance (neglecting clustering issues), there's only one instance of a particular entity bean class + primary key. It sounds to me like your talking about something much more like an entity. You can still get the guarantee you're looking for if you access the entity through a session bean, but the guarantee comes from the properties of the entity bean, not the session bean. Does that help any? Gary

RE: persistance
I haven't tried solving this problem myself, so am really just guessing. I wonder if the thing to do is stash your serialized class in JNDI, and then do a lookup and grab it when your session bean is instantiated? I'm assuming you need acess to the information in an EJB as opposed to a servlet; it seems that the rule against singletons is only for EJB's.

I've been working on getting Orion running in a production environment for a little while now and just when I thought everything was working fine I go to push to production and something load/volume related is creating massive slowdowns. Basically every 250 database accesses or so there is a long pause (20 to 60 second), where nothing occurs. During this pause the CPU load *drops* to practically nothing and our entire site is frozen. I'm not sure exactly where the problem exists; it could be our code, our configuration, or even a bug in Orion. The environment is Redhat 6.2, JDK1.3, Oracle 8i. Its a pure J2EE app, but we're not using EJB. I initially thought it might be a memory issue, but I've played with the JDK heap size and carefully watched memory utilization and thats also not the issue. I even considered that maybe Evermind/IronFlare might have a throttle (to push you to get a license) so I put one of our production licenses on the QA box. I've since gotten a load tester and can reproduce the problem. Oddly, it only happens on pages which require database access. Even more interesting is that it occurs more frequently on pages which utilize more than one connection. But thats about as far as I can narrow it. I've tried the 8.15 and 8.17 type4 jdbc drivers from oracle and we've tried Oracles ConnectionCacheImpl and Orions XADataSource implimentation, both show the same behavior (though both are using the Oracle Driver). I've also tried Orions jdbc debug and it shows nothing of interest. So far I've put about a week straight into finding it, and I've just about run out of ideas. I'd really be appreciative if anyone has any good suggestions on where to look. ANyone seen behavior like this before?

referring to a jar from an ejb-jar file/directory?
I have an ejb application running under orion. I want to restructure the code so that some common code is put into a jar. The problem is that I can't figure out a way, short of putting the jar in the orion/lib directory, to make the contents of the jar available to the ejb side of the application. The EJB-2.0-pfd spec says: The ejb-jar file must also contain, either by inclusion or by reference, the class files for all the classes and interfaces that each enterprise bean class and the remote and home interfaces depend on, except J2EE and J2SE classes. (page 486) Well, what does 'reference' mean? The only hint I have found is: An ejb-jar file does not have to physically include the class files if the classes are defined in another jar file that is named in the Class-Path attribute in the Manifest file of the referencing ejb-jar file or in the transitive closure of such Class-Path references. (page 487) Well, I'm going to try creating a manifest file with a Class-Path in it, but since I'm running out of a directory, not an actual ejb-jar file, I really doubt this is going to work!

I'm assuming it does, otherwise you would just use a stateless session bean. Here's some fodder for conversation: I don't think there is an EJB facility which will help you. SLSBs are pooled and can timeout, SFSBs have no lookup mechanism, can timeout, and aren't reentrant (although Orion, despite the spec, serializes calls, which is good), and entity beans will get all wacky because of the multiple instances you will get from an optimistic concurrency model. I could use a little help here. My limited understanding of entity beans suggests that if I create an EB using a particular key value, as long as I refer only to that same key value there would only be one instance of the EB. Is that not true because of optimizations that allow bean pooling of a particular EB for a particular value of that EB's primary key if 'optimistic concurrency' is assumed?

META-INF\ejb-jar.xml (and changed this file)
META-INF\MANIFEST.MF
TestHome.class
Test.class
You see, the EJB Bean is killed. Why I do that?
I want the EJB only installed on PC B. I think, that is a full Distributed System.
Orion server say's me; that EJB not define at PC A, but the System are going again. I
can call the EJB on PC B.
I think, my servlet need the Home and the Remote - Interface, that is the ground
for installed the Home/Remote Interfaces. Why don't loading the Orion Server at PC A
the Home and the Remote - Interfaces from PC B, where the full EJB installed?
I hope, you understand me.
Thanks for help again.

Hi.
I have two Orion-Server running on two different PCs. I want to lookup a

Re: Traversing JNDI namespace

Hi,
How can I find what's in an entity bean's java:comp/env namespace?
If I ask the InitialContext for a list of what is in it (using
initialcontext.list("") ) I get a list of things (mainly home interfaces)
plus entries for "java:comp" and "ejb" which are both Contexts.
If I ask for what's in "java:comp" I get a few strange entries, but NOT one
for "env", which is the one I would have expected.
If I ask for what's in "java:comp/env" I get nothing back (empty context).
Just wanted to report that I've had exactly the same experience,
assumed I must be doing something wrong given my slight experience
with JNDI.
I sure hope someone knows the answer!

However, lookups for entries named java:comp/env/foo succeed where they should.
Any ideas?

Re: Client hits STOP button..is there a way to detect this beforesen ding a response?
Interesting question. My instincts say you can't win as long as your data integrity is determined by your ability to determine the exact status when the situation is inherently a race condition. That may be overly pessimistic given that it takes the client a finite amount of time to stop one transaction and start the next, but still, I'd try a different approach. For instance, give each request a serial number, hold each response in the session separately, and build the serial number into the links of the output page. Then you know it will work, but the overhead is minimal (you're assuming that this won't happen often, so it's rare that you'll have multiple results sitting in the session). I haven't run into this problem yet, so I'm glad you pointed it out ;) Gary Today, Duffey, Kevin ([EMAIL PROTECTED]) wrote: Hi, I have a need to find out if the connection back to the browser from a servlet is still good or not, before an attempt to send the response occurs. Is this possible? I know when I do a response.sendRedirect() or requestDispatcher().forward() Orion will throw an exception if the connection to the browser (or client for that matter) has been terminated. The problem is..I want to check for this before an attempt is made, so that incase the connection is lost, I don't populate the javabean. I'll give a reason why this is necessary (and very helpful). I have my code organized into JSP pages, ControllerServlet/Action classs, JavaBeans and Session classes. Session classes are STATELESS classes, so that I can get ready to move to EJB when I get time. Each time a request is submitted, it goes to an action class method to be handled. The action class instantiates a new session class (I am not bothering with a pooled setup for session classes at this point as EJB will do this for me when I move to it). The session class performs some logic..usually database acitivty of some sort. The action class is then given a result (usually a Vector of some sort of objects). The action class then sets a bean variable to point to the vector of results. The bean is stateful and is session scope (HttpSession). At the end of the action, the response is forwarded to a JSP page. That page then uses the bean and its reference to results to display them. So here is the problem. If a user submits a form (say..to search for all clients) and lets say that search will take two minutes. 10 seconds later, the client sees he/she made a mistake on what they were searching for. As if often the case..they hit STOP on the browser, change their mistake and submit the form again. On the server..there are now two threads running..because the first one hasn't completed yet (assuming the user submitted the form the 2nd time fairly quickly). The 2nd request is quick..it populates the javabean reference to a Vector of objects say in 20 seconds. The response is sent back and the user sees a list of say 20 items. Now, while they are looking over this list, the 1st request they sent is still going on. At some point it too populates the SAME javabean with its results, which are now different than what the client is actually looking at on the page. The action tries to return its response but it finds its connection was terminated. It throws an exception (which I catch), and voila..the client sees nothing. Where the problem lies though..is when the first request populates the javabean that the 2nd request already populated. So when the user clicks on say item 3 of what he sees..it refers to item 3 in the results Vector that has now been replaced with the first requests results. Therefore, the information is incorrect. So, what I am trying to do is find a way that if the connection is no longer available BEFORE the bean is populated and anything else happens, it just stops in its tracks. That way..if the user submitted another request, the first one wont repopulate the bean with information that is inaccurate to what the client is seeing. Thanks for any ideas and info on this topic.
Re: Problems with CMP PrimKey...
Hey, I'm not too hip on CMP for EJB 1.1, but for 2.0 the prim-key-class is given if you have a custom primary key class; the primkey-field is used if no custom primary key class is defined.

Do you have the application defined in config/server.xml?

Gary, I tried it again per the suggestion you forwarded from support,

In case anybody else has been following this thread, here's the working

// WRONG: DataSource ds = (DataSource)
cxt.lookup("java:comp/env/OracleDS");
DataSource ds = (DataSource) cxt.lookup("jdbc/OracleEJBDS"); // RIGHT
Connection c = ds.getConnection();
So the moral of the story seems to be, don't use the syntax
"java:comp/env/myDS"; rather, use "jdbc/myDS".
Note I've substituted "OracleEJBDS" per the note from support which Gary
included earlier in the thread.
Finally -- 'cause I'm personally done with this thread for a while, ;-)

However, Orion not only has to compete with other commercial products like web-logic, but good open source EJB servers, like JBoss and JOnAS. It would only be fair to have good documentation to review, and to deploy a test sample to demonstrate Orion can work, for those funding the development and software purchases. We bought a copy of Orion for development, figuring that given the low price and the supposed availability of support for license holders, it would be worth the cost. Unfortunately, we have received zero useful support from Orion at this point. I'm trying to figure out if I've simply asked lousy/dumb questions, or if there really is zero support. Kinda hard to tell... Documenting something as complex as a J2EE server must be a daunting task, and I can't blame Orion for having trouble doing it. And even email support eats time like crazy. I suppose that's why it costs so much to buy the upscale servers, because they have the resources to provide documentation and real support. I still plan on working with Orion as long as I can stand the pain and can accomplish the job.

I am unable to use the list() method to traverse down into the env subtree, either that or there's nothing in the env subtree. The env subtree is an object of the com.evermind.naming.jv class, which implements Context, but list() on the env object returns an empty enumeration.

I think that probably today Karl Avedal and Mike are sick, because the don't talk clearly to us. The same happens with fail-over, connection pools and hot deploy, orion team has ignored my questions about those things because they are not interested in it. You should answer our questions. I do think that Orion is a good product but after betting for it, we have to be very sure what we are going to get. Think about it... Orion team. Kirk Yarina [EMAIL PROTECTED]
RE: Latest versions?
Oh, that is soo slick! Wow! But ain't this typical, I thought I'd read every single bit of text on the orion site, and I don't remember seeing this ultra-cool feature mentioned anywhere. These folks have an awesome product, but I guess selling it (as opposed to their core business of using it?) is pretty much second priority. Gary I keep coming across references to versions like 1.0.11. Where can I find the latest versions? cd /path/to/orion java -jar autoupdate.jar

Hi -- Unfortunately, it doesn't seem to work on Linux either, well, it didn't yesterday, although I've done an autoupdate since then. Didn't touch admin.jar. Gary I think there should be a mechanism for elevating the status of problems like this to the Orion team when quite a few people are experiening it.

I really like Orion, but I just can't recommend it to my employer if such fundamental features don't work. Ideally you won't be shutting down the server very often, however when you are configuring and testing you do it a lot. This issue has received a lot of traffic on this list, but I have yet to hear anyone for the Orion Team explain either a) what we're doing wrong to cause this error, or b) that it is indeed a bug in the software and it will be fixed in release 1.x. I understand Orion is hard to beat for the price, but I'd gladly pay more for a server I can shutdown! Nathan Phelps snip? Kirk Yarina [EMAIL PROTECTED]
Re: java.naming.factory.initial value for Orion?
Hi -- Just in case other folks read this list who are as frustrated as I have been this past weekend, putting 20+ hours into trying to get Orion to do ANYTHING but simply wake up, I wanted to say that I just got a simple Hello World (servlet + ejb) application working, and in retrospect most of my problems come down to a combination of ignorance of the J2EE specs, and a real lack of clarity in the specs and Orion doc about what is happening with JNDI and what all the different path-like critters in the various xml files mean and how they interact. I suspect it would be hard to do a much worse job than the Sun spec for the various DTDs. Comments like this one (from the J2EE deployment descriptor) really make my day: "The context-root element specifies the context root of a web application". Uh, yeah. And a context root is... At this point I feel like it's starting to make sense, but the learning curve is outrageous! So if you're feeling crazy, all I can say is: Hang in there! And read the various deployment specs (application.xml, ejb-jar.xml, web.xml, and application-client.xml) until your mind is jello...

There you will find a jndi.properties file with the correct properties (for an application client). It should look something like this: java.naming.factory.initial=com.evermind.server.ApplicationClientInitialContextFactory java.naming.provider.url=ormi://hostname/application-name java.naming.security.principal=username java.naming.security.credentials=password Of course you need to replace the values in with real values. Since I saw that this info was pretty well hidden, I'll add an FAQ entry about it immediately.

java.naming.factory.initial value for Orion?

Re: java.naming.factory.initial value for Orion?
Ok, bad sign, I'm answering my own posts. After winnowing through the contents of the orion.jar, I've determined that it's possible to use com.evermind.server.rmi.RMIInitialContextFactory for the value of java.naming.factory.initial, although I have no idea if it's a _correct_ value ;) Using that class for the initial naming factory, if I put in a valid rmi name like "rmi://localhost/" I get a message about "invalid username/password". Yikes, why is it so hard to get these things to work!? Back to the random-poke method...
