[JBoss-user] Urgent: JBoss Reference Needed.
Hi All! have submitted a proposal to a client recommending JBoss... hes still not really convinced.. he wants an article/resource/case study anything that says how JB is running successfully in a production environment. Preferably from an independent website and not from JBoss.org. Our competitors are recommending commercial appservers. Any Help would be appreciated.

RE: Problem after problem... (Re: [JBoss-user] http session clustering)
Well, if this application is buggy, it is buggy. Either you fix it, or you use another one. Take xPetstore: Sun says it contains the best j2EE patterns. Take a subset of this app, cluster it, and you end-up with a clustered j2eE app. Good luck, Sacha -Original Message- From: Joao Clemente [mailto:[EMAIL PROTECTED] Sent: vendredi, 4. juillet 2003 01:41 To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: Problem after problem... (Re: [JBoss-user] http session clustering) sorry for replying so late, but here goes: No, my problems are still not solved... And I almost gave up on this... This is my university thesis, and I'm already almost a year late (it should take a year and I've started my research almost two years ago). If this is not finished in the 2 year-time, the thesis will be cancelled by the university. I'm suposed to use JBoss to provide a scalable, fault-tolerant and high-available middleware infra-structure for a j2ee app that is being developed by another person.. another thesis that is being developed at the same time, a kind of a webmail on steroids.. This j2ee application is build on top of a already developed open source webapplication (servlet+jsp). It was redesigned to use EJB's aswell. Then it was expanded with the help of a couple of more external libraries of other independent open-source projects.. So we're talking about a webapp that was redisegned to be a j2ee app, and then glued to some other libs and projects and with some extra code developed here... Put a Ldap connection here, a jabber server there, a mailserver somewhere else and with a bit of luck you get something like this... About 10 months ago, I should had delivered tested results on how the jboss cluster can improve the scalability and fault-tolerance of this application. I'm failing miserably every test I make... day after day I crash into another problem, and I'm unable to get those test results... I'm not saying this is JBoss's fault... No. I've found a couple of bugs that were JBoss and Javagroups related, as you (sacha) can certainly remember. But those were not the reasons I'm failing every time I try... This app sucks. Thats the truth I'm already seeing for a long time ago and it's exactly that that my thesis advisor (togheter with the other theses developer and advisor) is refusing to see.. Sure.. but the app works fine, they say. It's a problem on your side, they say... It's your work to get that thing usable under load, it's what your research is suposed to do, they say.. And, actually, if we use 1 (ONE!!!) client (wich, btw, must be InterntExplorer) , with 1 (A SINGLE ONE!!!) jboss server, and you test it manually... it works.. But, for instance, - The app uses non-serializable objects all over the http session. This ceartainly gives us a hard time getting fault-tolerance (or failover) to work, besides the problems with the load-balancing... - The owner of the original project (the one that was redesigned here to have ejb's besides servlets and jsp's) admitted that it never tought of it to be clustered, and had no ideia of what was to be done for it to be runnable in a cluster... About three or four months ago I started writing java test programs using httpunit to load the app.. I've designed a simple client model that would just do four or five steps in the web app... Simple, right? Then added a threading model so I could have n similar clients accessing the webapp... Again, simple... I decided to test WITHOUT a cluster. So, there as been at least 3 months that I do NOT have a load balancer, i DO NOT have a clustered jboss setup, there is just 1 jboss server and my client application... Results? I'm almost willing to wait 'till the 2 years of my thesis end, my university cancels it, so that I can start something new from the scratch... With NO cluster involved: - with 1 client ,if I run my test case (get hompage, login, check mail, logout) for 6 times, I would get locked. End of story. - with 2 clients, would get about the same results.. - with 4 clients, I would get little more than exceptions... oh, btw, in most of these cenarios, I' would not even be able to use the application manually, as it would enter a cicle redirecting me for the start page (it's a feature of this app: if something goes wrong then redirect to start page)... until I shutted down jboss and started it over (trying to undeploy the app would lock jboss) and no, it does not stop here... after some time, we found out that a singleton object of that j2ee app was unable to be runned concurrently and would cause the exception... gimme some more headaches, and we find out that the locking was due to one of the external libs that were being used that, by some reason, locks under yet to be understood circuntances.. oh,

Re: [JBoss-user] Entity bean Attribute Changed Notifications
Brian JBoss AOP would certainly do what you want, it wouldn't be that hard to write an Interceptor that generated your notification for the setXXX methods you're interested in. To do the same within the CMP class is more difficult ... the attribute setXXX methods have to be abstract, that's part of the EJB contract. You could write wrappers around each setXXX method but then you'd have to ensure every client used the wrappers, and since the setXXX methods have to be public, that's not enforceable. You could edit the XDoclet template that generates the CMP file so that your setValue method generated the notification, but, as you say, this wouldn't trap the attribute setXXX calls. At least this way you wouldn't have to handcode the CMP class, XDoclet would generate it for you. I've done very similar stuff myself for, eg, generating JMS messages on session bean method calls, but in that case, the methods weren't abstract ... that's the real problem with the entity bean attribute methods. I'd say AOP is your best bet. The latest release, DR2, has added the ability to declare interceptors on a per-method basis, although the XDoclet support hasn't quite caught up with that (it will soon, honest :) HTH Andy - Original Message - From: Brian Wallis [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Friday, July 04, 2003 3:28 AM Subject: [JBoss-user] Entity bean Attribute Changed Notifications I need to generate some sort of notification when attributes are changed on certain entity beans. The notifications need to contain the identity of the authenticated user and the old and new value of the attribute (or just the new value would be OK). (I'm running 3.0.7 jboss) I'm not sure how I can do this. We are generally using value objects to set the values in the entity bean so more than one attribute may change at a time and we are using xdoclet to generate the various interfaces and support classes. We may be able to hand code the xxxCMP class that is currently generated from the bean class and add the functionality to the setValue method(s) but that gives me another file to maintain which I'd rather be generating. It also means I miss direct calls to the setXxxAttr() methods. I could use triggers or some other database centric mechanism but would rather not (not portable, more to maintain and break). Does anyone know if this is supported by the platform in any form or if xdoclet can be coerced into generating the required code? Using aspects could do it very neatly by wrapping each setter of the entity beans in an aspect that reads the old value, calls the setter and then generates the notification for me. I could do this with aspectJ but I'm not sure about the new 4.0 jboss aspects. any suggestions welcome. thanks, brian wallis... --- This SF.Net email sponsored by: Free pre-built ASP.NET sites including Data Reports, E-commerce, Portals, and Forums are available now.

I know that the JBG guys will say: Hey, Jetty is still there so you can still use it. Well, I have to change configuration and so on and so on. But who cares about the user? I am waiting for the CDN release. Hope there will be a branch in CVS for these guys where we can get a JBoss4 maybe without the fancy AOP? But with JBossDO? Or a web-GUI for adminstration (not the human unreadable jmx-console which can only be understood by developers rather than admins)?

Subject: [JBoss-user] [JBoss-user]Container Transacted MDB ?
Guys,
I want my Message Driven Bean under Transaction boundaries.
Transaction should start when onMessage() call is received.
Here's my deployment descriptor which says my MDB is
ContainerTransacted and It requires a New Transaction.

This MDB calls an helper class which inturn calls a bunch of
Entity Beans and updates the database. In Exceptional
scenario when I want to rollback the whole Transaction, I use
this.context.setRollbackOnly();
public void onMessage(javax.jms.Message message) {
try {
... do the business
} catch(Exception e) {
this.context.setRollbackOnly();
}
}
When Exception occours, I get a message saying
setRollbackOnly() must be called only from a Transacted Bean.
Why does the container think that my MDB is not Container Transacted.
Please advice me If I'm missing out on anything.

However , I am worried with this problem. Do You can guarantee me that whether always I close my connections, the Pool will work fine? I doubt you will find any open source project that will guarantee anything. However, I will point out that datasources are one of the most heavily used components in JBoss.

I don't want to get into a protracted discussion here, but there are many reasons why a Tomcat-based implementation might not exhibit exhausted connections when JBoss does. For example, JBoss works in a persistent environment. That is, JBoss run continuously, and your client makes intermittent use of the services it provides. Between those uses, things like database pools continue to exist. Things you do in Tomcat, on the other hand, typically have shorter lifetimes. Much of the time, variables exist only for the duration of a request, so once a request is finished, everything gets cleaned up (assuming things are working properly.) There are other options, of course; you can choose to give things session or application lifetimes. One of the difficulties in database pooling in a JSP environment is that there is no place to put a shared pool. At any rate, I provided one suggestion in my last message which may allow you to determine in a JBoss environment if you are indeed leaking connections. Edgar Silva wrote: Hi Roullier, this behavior of the JBoss's DataSource is very strange, because I solved this trouble changing the Datasource from JBoss to TomCat. I Know that TomCat uses Jakarta Commons DBCP, and with this Container I solved all my troubles, when JBoss arrives in a number of connection greater than 200 ,Then JBoss Crashes. This number was defined in XML Configuration. The right behavior from a DataSouce that I Believe is: Make the Connections and after client uses it, this object will be consumed by other client. When I made the deploy of the same application, changing only lookup statement to TomCat Requirements, The Application is working fine now, And in each test I had only of 2 to 6 Connections established. Then I am in doubts about JBoss's Datasources to provide Connection Pool. But, I know that can be my technical problem, however I had been using several other J2EE Containers like Borland, BEA and IBM , And I do not remember of fails like this. I will buy the JBoss Documentation, then who knows I will can understand it better. Because is like a friend talks: The software is free, however the work is not slave. And I hope solve many problems after read some Chapters in JBoss's Documentation. I like too much JBoss, in addition to this I am trying to migrate many projects to JBoss. Because is free, and I Believe in the Project. If you know some article or resource talking about Connection Pooling of Datasouces in JBoss would be cool.

[JBoss-user] CMP persistent field using relationship-field fk column
Hi, I have a cmp question: We have bean that consists entirely of CMP relationship fields. When we xml-encode this entity bean's contents, we simply want the primary key, and the foreign keys. In an effort to avoid loading the related beans, I've added persistent fields that point to the fk-columns. Amazingly, this seems to work. However, after calling a finder and then accessing the persistent fields of each bean that is returned, I see an update called for every bean on the database log. First, is there a less crazy way to directly access the fk value without loading the related bean? Secondly, why are there these unnecessary updates to the db, and is it possible to avoid them?

[JBoss-user] Is there a maxNewConnections limit set to +-about 20-30 somewhere?!?
The new problem I'm having: Trying to figure out the maximum number of concurrent connections that my server deals with, I'm being able to open more than 20 connections at a time, and less than 30 connections... The strange thing is that this value only applies to the new connections I'm trying to open... For instance, supose I try to start 40 threads and 10 fails to connect. 30 are connected. Now, again with the same 40 threads, I try to do another request. the 40 threads work fine! So, I supose that this second interaction is of 30 already active connections + 10 new connections, so the server does not complain... There doesn't seem to be a magic number... sometimes I get 28 connections ok, sometimes I get about 25.. I tought of checking the http listener configuration.. but I have: New class=org.mortbay.http.SocketListener Set name=MinThreads10/Set Set name=MaxThreads100/Set and this value does not match the cenario I'm having ... I changed the falue for 50/200 and I kept having problems so it's not from there... Any other places to look for?

[JBoss-user] Re: Problem after problem... (Re: http session clustering)
Not to fuel your fire, but it really sounds like poorly written ejb's and jsp's. When you get into that situation there is no magic cluster to save it. Also I don't know the history or details of this story, but... What commit option are you using? Try option A with cache invalidation. Make sure any beans doing selects are deployed read-only. If you are using tomcat, make sure the max proccessors and acceptcount are high enough. Make sure the JVM is getting enough RAM. Try a different JDK. So many things, and I don't know your story, I'm sure you tried all of these, but I hope I maybe helped. Cam Joao Clemente wrote: sorry for replying so late, but here goes: No, my problems are still not solved... And I almost gave up on this... This is my university thesis, and I'm already almost a year late (it should take a year and I've started my research almost two years ago). If this is not finished in the 2 year-time, the thesis will be cancelled by the university. I'm suposed to use JBoss to provide a scalable, fault-tolerant and high-available middleware infra-structure for a j2ee app that is being developed by another person.. another thesis that is being developed at the same time, a kind of a webmail on steroids.. This j2ee application is build on top of a already developed open source webapplication (servlet+jsp). It was redesigned to use EJB's aswell. Then it was expanded with the help of a couple of more external libraries of other independent open-source projects.. So we're talking about a webapp that was redisegned to be a j2ee app, and then glued to some other libs and projects and with some extra code developed here... Put a Ldap connection here, a jabber server there, a mailserver somewhere else and with a bit of luck you get something like this... About 10 months ago, I should had delivered tested results on how the jboss cluster can improve the scalability and fault-tolerance of this application. I'm failing miserably every test I make... day after day I crash into another problem, and I'm unable to get those test results... I'm not saying this is JBoss's fault... No. I've found a couple of bugs that were JBoss and Javagroups related, as you (sacha) can certainly remember. But those were not the reasons I'm failing every time I try... This app sucks. Thats the truth I'm already seeing for a long time ago and it's exactly that that my thesis advisor (togheter with the other theses developer and advisor) is refusing to see.. Sure.. but the app works fine, they say. It's a problem on your side, they say... It's your work to get that thing usable under load, it's what your research is suposed to do, they say.. And, actually, if we use 1 (ONE!!!) client (wich, btw, must be InterntExplorer) , with 1 (A SINGLE ONE!!!) jboss server, and you test it manually... it works.. But, for instance, - The app uses non-serializable objects all over the http session. This ceartainly gives us a hard time getting fault-tolerance (or failover) to work, besides the problems with the load-balancing... - The owner of the original project (the one that was redesigned here to have ejb's besides servlets and jsp's) admitted that it never tought of it to be clustered, and had no ideia of what was to be done for it to be runnable in a cluster... About three or four months ago I started writing java test programs using httpunit to load the app.. I've designed a simple client model that would just do four or five steps in the web app... Simple, right? Then added a threading model so I could have n similar clients accessing the webapp... Again, simple... I decided to test WITHOUT a cluster. So, there as been at least 3 months that I do NOT have a load balancer, i DO NOT have a clustered jboss setup, there is just 1 jboss server and my client application... Results? I'm almost willing to wait 'till the 2 years of my thesis end, my university cancels it, so that I can start something new from the scratch... With NO cluster involved: - with 1 client ,if I run my test case (get hompage, login, check mail, logout) for 6 times, I would get locked. End of story. - with 2 clients, would get about the same results.. - with 4 clients, I would get little more than exceptions... oh, btw, in most of these cenarios, I' would not even be able to use the application manually, as it would enter a cicle redirecting me for the start page (it's a feature of this app: if something goes wrong then redirect to start page)... until I shutted down jboss and started it over (trying to undeploy the app would lock jboss) and no, it does not stop here... after some time, we found out that a singleton object of that j2ee app was unable to be runned concurrently and would cause the exception... gimme some more headaches, and we find out that the locking was due to one of the external libs that were being used that, by some reason, locks under yet to be understood circuntances.. oh, and that lib was now deprecated.. ok, now what? sending
Re: [JBoss-user] Question about CMP entity
Marco I tried your code (adapting it to my project
- I changed the key and the package names, substantially) but I found what I
think could be a bug.
I had the tb_sequence table with the first key set
to 10, but the returned value (the one to which I set the primary key) set to
11. I discovered the reason in the Session bean getNextId method, as once you
retrieve the value then you add 1:
public Integer getNextId(String
sequenceName) throws
FinderException, SequenceException, CreateException {
//Get
cached block
Integer nextId = (Integer)
blocks.get(sequenceName);
if
(nextId == null || ((nextId.intValue() % BLOCK_SIZE) == 0))
{ nextId =
getNextBlockStart(sequenceName);
}
//This is
the part of code - Marco Tedone
nextId = new Integer(nextId.intValue() +
1); blocks.put(sequenceName,
nextId);
return
nextId;
}
So, I updated the line
nextId = new
Integer(nextId.intValue() + 1);
with
nextId = new
Integer(nextId.intValue);and everything worked fine.
Marco

Subject: Re: [JBoss-user] Question about CMP
entity
Could you please forward some
example?
You can use thissame bean to create ids for any entity, or
create a sequence bean for each entity to get some performance boost.
Observe the for (;;) loop and the TransactionRolledbackException catch, that´s the tricky
part.
there you go:
