Re: [JBoss-user] Login Module Question
Scott, you are almost certainly right, but I am at a loss as to how to do what I need to do. My webapp is a servlet and a set of html and jsp pages, all protected by JBoss security. If the user enters at the "top" of the site he runs the servlet and all is well. If he later uses his browser history or just remembers the url for one of the pages and enters directly in to the "middle" of the site, JBoss security protects the page and forces authentication, but the user gets to the page without running the servlet and his session info is not set.

Re: [JBoss-user] castor and transactions
throwing an applcation exception doesn't automatically rollback the tx. you'll need to call setRollbackOnly on the bean context for that to happen - do it before you throw the exception as a general rule. I've been told that this behaviour is in the spec to make it compliant with CORBA... someone might want to elaborate on the reasoning behind it though. cheers dim On Thu, 27 Sep 2001, Dominik Baranowski wrote: > hello, > > I'm trying to integrate castor into jboss.

[JBoss-user] castor and transactions
hello, I'm trying to integrate castor into jboss. Everything seems to be running fine. I'm wondering how I can get a data object managed by castor to be included in a trasaction started by the container. (container managed transactions) that is, I have a transacted session bean which asks Castor for an object. I change the object and then I call update on the database object I got from castor, before I exit the session bean method (and therefore commit)I throw an exception from the session bean which should cause a rollback and no changes commited to the database. is there a way to do this? the bahavior that I'm seeing is that the change goes into the db thanks -dom ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
RE: [JBoss-user] Performance...
Lots of stuff (been doing Java for a while ;-), but here are some techniques (in extremly short format) when you have gc problems. 1) Monitoring Find out what does not get collected. Either use a tool like OptimizeIt - but I find them a bit clunky to use or do it "by hand": Identify your "key" objects - the ones which you need to create for every page transition / request and instance count them (+1 in the constructor -1 in finalize) and make the info available at any time (we have a "MemoryStatus" servlet / dump thread). Finalizing does not mean it gets collected, but not being finalized means it won't get collected. You need to be somewhat "strategic" on which objects to keep track of so the monitoring does not slow your app down. 2) Write "Destructors" Once you know what does not get collected, fix it. For frameworks I found it useful to have a _clean() method which gets called from the framework to unhook references (especially to cut circular references) Especially key an eye on hashtables, vectors and any other reference hugging data structures and clear() them when they are no longer needed. 3) Write a GC kicking / monitoring thread Search this list for "GC kicking bean", I posted the code for an MBean for Jboss a few weeks ago. Doing all this works fine for server side stuff. Last time I was involved with client side (swing) Java was two years ago and it was almost impossible to make Swing not leak - the API just did not allow to clean up after you are done (e.g. removing all listeners was often not possible) and the gc was not good enough to collect the complex structures. This might have changed with 1.3 - I don't know. Comments anyone? Hope this helps. Am interested in any futher approaches.

RE: [JBoss-user] JBoss/Linux thread probs
-server is the server version of hotspot. -hotspot is the default (a client orientated version), and -classic is the old version of the JIT. If you look in your jvm.cfg file you'll see a list of what's installed on your system. Now, as a point of fact, I see the -hotspot (sometimes known as -client) outperforming the -server setting.

RE: [JBoss-user] JBoss/Linux thread probs
Removing Server is just going to change the way HotSpot works. I don't think this is going to affect your problem directly. Check your ulimit's. Sometimes running out of open file descriptors will mask it self as a process limit problem. Note, this is a java issue, not a JBoss problem. Also, I've had much better luck with 2.4 kernels in handling large numbers of java threads. Volano, WebLogic and JBoss all benchmark better under 2.4, mostly due to the threading improvements.

RE: [JBoss-user] HELP! java.lang.Error: id may not be null
The reason we can not use a primary key that is automatically assigned in the database has to do with the limitations of the JDBC drivers. Until JDBC 3.0 there was no way to know the final value of the auto generated columns in a INSERT statement, so there would be no way to know the key for the new entity. I know that there are some proprietary extension that allow for this, but it is not realistic to support all of the vendors. So, expect that when JDBC 3.0 drivers are commonplace JBoss will support DB generated PKs. Until then you will still have to use decoupled key generator. -dain > -Original Message- > From: danch [mailto:[EMAIL PROTECTED]] > Sent: Thursday, September 27, 2001 1:18 PM > To: [EMAIL PROTECTED] > Subject: Re: [JBoss-user] HELP! java.lang.Error: id may not be null > > > Or decouple the key generation from the row insert so that > you can get > the key from the database withing ejbCreate, then assign that > value to > your primary key field > > Adam Esterline wrote: > > > You cannot use a DB generated key with CMP.

RE: [JBoss-user] HELP! java.lang.Error: id may not be null
I am assuming that you are leaving your pk field null in the ejbCreate, because you are using Oracle's sequence field. JBoss does not like it when your pk field is null. If you notice, in the example you are using, they do assign the id field a value in the ejbCreate. The bottom line: You cannot use auto generated fields in CMP, unless you do some magic (use a mbean, a session bean, a helper). JBoss, or any app server that I am aware of, does not understand how to get an auto generated field from a DB with CMP.

Re: [JBoss-user] HELP! java.lang.Error: id may not be null
Even if you don't have the pk as a parameter to ejbCreate, you still need to set it in your code. Popular ways include having a session bean or an mbean to get the next sequence value, and having your ejbCreate get the value from one of these. At least if you use an mbean, you can set your sequence to step 10, 20 or whatever and hand out the in-between numbers from your mbean, reducing db access. If anyone else is inserting into this table you probably want an insert trigger that supplies the sequence value only if the pk is null. There have been long discussions (wars?) about how to do this in the user list -- none too recently. david jencks On 2001.09.27 13:20:39 -0400 [EMAIL PROTECTED] wrote: > > We have a CMP entity bean which has an ejbCreate(Integer, String, String) > method which returns null since the database should generate the key for > us > (from an Oracle 8i sequence). > The ejbCreate is declared to return an Integer (the type of the primary > key > field). > > Any pointers on where to start looking? > > The error we get is: > > [IniConfig] TRANSACTION ROLLBACK EXCEPTION:id may not be null; nested > exception > is: > java.lang.Error: id may not be null > [IniConfig] java.lang.Error: id may not be null > [IniConfig] at org.jboss.ejb.CacheKey.(CacheKey.java:67) > [IniConfig] at > org.jboss.ejb.plugins.EntityInstanceCache.createCacheKey(Enti > tyInstanceCache.java:48) > [IniConfig] at > org.jboss.ejb.plugins.CMPPersistenceManager.createEntity(CMPP > ersistenceManager.java:237) > [IniConfig] at > org.jboss.ejb.EntityContainer.createHome(EntityContainer.java > :616) > [IniConfig] at java.lang.reflect.Method.invoke(Native Method) > [IniConfig] at > org.jboss.ejb.EntityContainer$ContainerInterceptor.invokeHome > (EntityContainer.java:843) > [IniConfig] at > org.jboss.ejb.plugins.EntitySynchronizationInterceptor.invoke > Home(EntitySynchronizationInterceptor.java:231) > [IniConfig] at > org.jboss.ejb.plugins.EntityInstanceInterceptor.invokeHome(En > tityInstanceInterceptor.java:154) > [IniConfig] at > org.jboss.ejb.plugins.EntityLockInterceptor.invokeHome(Entity > LockInterceptor.java:108) > > > ___ > JBoss-user mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/jboss-user > > ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

You cannot use a DB generated key with CMP. You must use BMP or some other mechanism, if you want to use a DB generated key.

[JBoss-user] JBoss/Linux thread probs
Title: JBoss/Linux thread probs Im develloping my app on Linux RH 6.2/JBoss 2.4 and HypersonicSQL. My app has: - 4 session beans - 6 entity beans using CMP - 4 MDB - 120 test cases. When I start JBoss, they are 48 threads that are spawned. When I run all my test cases the 1st time , 230 threads are spawned the 2nd time 340 threads the 3rd time 500 threads until my JBoss crashed because too many processed are spawned. I understand that Linux thread managemenent is not the best, but how can I configure my JBoss in order to reduce that threading behaviour (gc config? caching size? pool size?). Does anyone has a clue? By the way, when I run my test-cases on Win2K, I have no prob..

Jo napot kivanok (this is as far as my Hungarian will go) We have a very similar setup Single CPU P4-1.4G, 1G RAM, fast SCSI disk running RH 7.1, SUN JDK1.3.1, Apache, Resin, JBoss2.4 and Postgres. This setup runs around 50 concurent users mucking around with the web app easily (we did not push it further as we only use it in-house at the moment) and we have it running for weeks with consistent response times. We talking hundreds of thousands of bean method invocations and millions of SQL queries.

It does a separate "login" operation in a different database and writes a cookie so that some data from that database is available to subsequent operations. I am guessing that what I have to do is subclass DatabaseServerLoginModule and run my code from that subclass. Which I have started to experiment with, but JBoss keeps saying it cannot find my class.

Re: [JBoss-user] Security question on Webapps
So what does the "login servlet" do?

Re: [JBoss-user] Security question on Webapps
Dim, I am using realms and form based login. The user doesn't request the login PAGE directly, it requests the login servlet which is a protected resource. That bit works. The problem is that there are other protected resources and if the user requests one of those, after authentication, the user gets them, but I need the login servlet to be run whenever they are accessed.

RE: [JBoss-user] Refresh or Reload Bean
Hi Ole, thanks for your advice. I'am not totally clear that I know what you exactly mean. Do you have a short example for me? It sounds that the isModified() is for prevent that it will an update to the DB performed. Is it right? I have implemented proxies that call the bean to increase the performance but when do a findByPrimaryKey it will took 2s an more. Is this normal?

Problem is that there is a delay from the time the other app changes the db until your bean code receives the notification. In this time, your bean _not_ do a load unless commit option A is used, and then write the old data back to the db on the store at the end of the transaction. If many transactions do not change your beans, you may get petter performance if you implement the isModified() hack to avoid doing a store of unchanged data.

Re: [JBoss-user] Security question on Webapps
If you're using security realms and form based login (not sure if you are) then you shouldn't ever directly request the login page, simply request the protected resource and let the contain send the login page as required and then continue the user onto the requested (protected) resource. cheesr dim On Thu, 27 Sep 2001, Gerry Duhig wrote: > Hi! > > I have configured a webapp to be deployed by the embedded Tomcat and > use the JBoss security system to protect it.

[JBoss-user] JBOSS 2.4.1 and JacOrb 1.3.3
Hi, since several months I'm using EJBs deployed with JBoss 2.2.2 able to connect with Corba servers using JacOrb 1.3.3. I tried yesterday to upgrade to JBoss 2.4.1 but it seems that I'm not enable to connect with the ORB. As far as I can tell I have exactly the same configuration ie: I add on the jboss.properties file the following lines # Launch the jacorb ORB as the default orb org.omg.CORBA.ORBClass=org.jacorb.orb.ORB org.omg.CORBA.ORBSingletonClass=org.jacorb.orb.ORBSingleton add the jacorb.jar in the CLASSPATH and finally I have a jacorb.properties file on my home directory The error I get is : org.omg.CORBA.INITIALIZE can't instantiate default orb implementation org.jacorb.orb.ORB and I'm using the same jdk (1.3) on W2K.
