Re: [JBoss-user] principal=null problem
Are you speaking of EmbeddedTomcat? If so, in the contrib/tomcat module, there is a RequestInterceptor called org.jboss.tomcat.security.JbossRealm that will alleviate this problem. It's difficult to explain in words, but if you study the use-case diagrams on the JBoss website, it's easier to understand. The basic idea (I think) is that JAAS expects it's client to be in a separate VM. The code in the server login modules in JBoss that are responsible for setting the principal that normally gets called during a login never gets called when the client is in the same VM. Study the diagrams -- I found them infinitely understandable. ++jeff Khaled Aboudan wrote: Hello, I wrote LoginModules for JAAS Authentication. Calling secured EJBs from a local client works fine. However, calling the same EJBs from a Tomcat causes a security exception stating that the principal is null. I have seen this discussed in many different threads. But I still have not seen any final verdict about the subject. Some people suggested to use 'Tomcat Style login Interceptor' ...is this the way to go? Could someone explain why this happens? Thanks in advance for your help. Regards, Khaled ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
Re: [JBoss-user] Are readonly beans/transactions possible?
We noticed similar things and decided to change the transaction setting our read-only EJB methods from Requires to Supports. It eliminated a lot of the contention. I hope this helps. ++Jeff P.S. -- this is done in the deployment descriptor for your bean(s) (ejb-jar.xml in JBoss). Sven Van Caekenberghe wrote: Hi all you jboss/ejb gurus, While stress-testing an application using jboss we encountered some problems. We're not sure whether we did something wrong in the ejb development or in the deployment or what. We think we need at least some help in how to do 'readonly beans/transactions'. Problem description: System: jboss 2.2.x, interbase 6.x, jdk 1.3, linux mandrake 7.2 Server code: session bean facades working with multiple entity beans (some with subobjects) Deployment: container managed persistence and transactions, requied transactions, default commit option A Client code: swing gui clients, junit tests clients Problem: Running more than one client we get locking-waiting, lock contention, but sometimes also failed transactions. The thing is that you would expect these problems when trying to modify the same object, but it also seems to happen when reading data from the same object (which of course happens a lot). It seems that even a call like PersonData[] getAllPersons() on a session bean (returning serializable copies of entity beans) needs full exclusive read/write locks on all objects involved in the transaction, even if we are just reading data. As we see it, such behavior will never scale. Question: How do you do readonly beans or access beans in readonly transactions, either in ejb or in jboss? This must be a common situation. I hope the answer is not to avoid using entity beans for readonly data access and to access the database/datasource directly (we like cmp too much to let it go). All help is greatly appreciated!

Re: [JBoss-user] Does JProbe work with JBoss?
Saw this same problem on Linux w/ Blackdown 1.3. Something about a "profile" field needs to be added. :-( Bill Burke wrote: Has anybody ever gotten JProbe to work with JBoss? Optimizeit seems to work, but I really hate the UI. JBoss has problems loading CMP JAWS entity beans with JProbe.

Re: [JBoss-user] What version works with both PetStore and JBuilder?
There is a tag in CVS that you can use to pull out the source code that matches the binary distributions on the site: JBoss_2_2_0_Final. I hope this helps. ++Jeff John Menke wrote: I am using JBoss2.3 beta (the current CVS snapshot). I have built embedded tomcat and everything appears to work fine as I have installed the Enterprise Javabeans Examples and they work. My problems are 1. Trying to debug my code in JBuilder4 2. Trying to run the sample application I have followed the Howto's for both JBuilder4 and PetStore, but JBuilder gives me errors when I try to run a project JBuilder Errors are Error at org.jboss.util.ClassPathExtension.postRegister (NullPointerException). I have followed the instructions in the Howto... is this something to do with running the 2.3 beta. Petshop Errors are not being able to build the petshop.ear file. Should I be using an earlier version of JBoss? If so, where can I get it? The only source distributions you can get are the CVS snapshots and they are the current versions... ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
