[JBoss-user] JMS vs ASYNC Log4J Appender
We log a ton of stuff and are having problems caused by synchronous logging blocking the appserver when linux rotates other various logs in the system. So we're considering using the ASYNC or JMS appenders. If we use the JMS appender we'll write a quick MDB to log all messages synchronously. Does anyone have any experience with these appenders in a high volume? Are there things to watch out for with either? Are there any key advantages or disadvantages of using JMS vs ASYNC? The obvious one is that JMS is sent to a topic so we'd have control over what we do with the log messages. Is there much more overhead with JMS vs ASYNC? In the past someone mentioned that the ASYNC appender can deadlock. Has anyone else experienced this? When it deadlocked, what happened? Did log messages just stop getting delivered, or did it take the whole server down? thanks. .peter
[JBoss-user] EnityBeans: Optimistic Locking Help
Can JBoss handle cmp optimistic locking that spans web requests? Here's the scenario that i'm trying to get working: Open two browser windows and display a value for a sample field. Update the value on one. Then update the value on the second, without refreshing first, and i'm hoping to get an exception signifying the stale data displayed, but i don't the update works fine. If this is possible, how do i make this happen? I have constructed a very simple sample project based on the optimistic locking section in the paydocs and have tried all but the UID method of locking but can't seam to get it to work. I'm wondering if someone might be able to identify what i have wrong. The sample project can be downloaded here: http://www.sharpuniverse.com/jboss/entitybeanlocking/sample.zip All you'll need to is set your jboss install dir in the build.properties then run the deploy target and go to the entitybeanlocking context. The JSP page reads the value from the db, puts the entitybean in the session and displays the current value to the page. On subsequent requests it gets the entitybean out of the session. The update servlet gets the entitybean out of the session and updates the value. In order to get optimistic locking working, it sounds like i need to get and set the value from the same reference, hence why i'm putting the entity bean reference in the session. The documentation refers optimistic locking working within the transaction, which could be my problem considering i'm executing across multiple web requests. If this is the problem, can anyone suggest a strategy for getting it to work. thanks. .peter -- CONFIDENTIALITY NOTICE: This e-mail message, including any attachments,is for the sole use of the intended recipient(s), even if addressed incorrectly, and may contain confidential and privileged information.

[JBoss-user] ASYNC Log4J Appender
A couple of questions about the log4j ASYNC appender: Considering that we're not allowed to spawn off threads in ejb's, is the ASYNC appender J2EE compliant? If it's not, does it matter, considering it's supplied resource from the appserver? If the VM crashes, we'd presumably loose whatever had not been written to the log right? Does anyone have experience with how much this might be? Is there any way to quantify it, such as 10sec of the log or something? Or is it pretty resilient to losing that last little bit of data. thanks. .peter -- CONFIDENTIALITY NOTICE: This e-mail message, including any attachments,is for the sole use of the intended recipient(s), even if addressed incorrectly, and may contain confidential and privileged information.

Re: [JBoss-user] JBoss On Linux
Is there a way to tell if i've run out of file descriptors? thanks. .peter David Ward wrote: Peter, I've read others' responses to your problems, and they all seem to be addressing the wrong thing: performance. What you describe does not sound like a performance problem (neither of speed nor memory management).

On Linux/UNIX based systems, socket connections (like to your mailserver and database) - not just files - use file descriptors.

It may be there's one in your application (that runs in jboss), and then the cron runs that might require a lot of descriptors too. Together, they could use up to your limit.

[JBoss-user] Jetty: Detail on JSP Errors?
I've inherited some bad JSP pages, that are full of code and have no error handling. Pity me! Whenever there's an unhandled exception in the code on a page, we get one of JasperExceptions and stacktrace below. The correct long term solution is of course to get the code out of the JSP pages. The short term solution is at least implement proper error handling, which we'll do for the next release. In the meantime, i'm wondering though if there is any magic flag in Jetty to get it to generate more helpful/meaningful error messages that might help us determine what the problem on the pages are. thanks. .peter Exception StackTrace: org.apache.jasper.JasperException at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:254) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:295) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:360) at org.mortbay.jetty.servlet.WebApplicationHandler.dispatch(WebApplicationHandler.java:294) at org.mortbay.jetty.servlet.Dispatcher.dispatch(Dispatcher.java:192) at org.mortbay.jetty.servlet.Dispatcher.forward(Dispatcher.java:129) at com.emsystem.web.MainController.doPost(MainController.java:104) at com.emsystem.web.MainController.doGet(MainController.java:147) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:360) at org.mortbay.jetty.servlet.WebApplicationHandler.dispatch(WebApplicationHandler.java:294) at org.mortbay.jetty.servlet.Dispatcher.dispatch(Dispatcher.java:168) at org.mortbay.jetty.servlet.Dispatcher.forward(Dispatcher.java:129) at MyForwardingServlet.service(Unknown Source) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:360) at org.mortbay.jetty.servlet.WebApplicationHandler.dispatch(WebApplicationHandler.java:294) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:558) at org.mortbay.http.HttpContext.handle(HttpContext.java:1714) at org.mortbay.jetty.servlet.WebApplicationContext.handle(WebApplicationContext.java:507) at org.mortbay.http.HttpContext.handle(HttpContext.java:1664) at org.mortbay.http.HttpServer.service(HttpServer.java:863) at org.jboss.jetty.Jetty.service(Jetty.java:460) at org.mortbay.http.HttpConnection.service(HttpConnection.java:775) at org.mortbay.http.HttpConnection.handleNext(HttpConnection.java:939) at org.mortbay.http.HttpConnection.handle(HttpConnection.java:792) at org.mortbay.http.SocketListener.handleConnection(SocketListener.java:201) at org.mortbay.util.ThreadedServer.handle(ThreadedServer.java:289) at org.mortbay.util.ThreadPool$PoolThread.run(ThreadPool.java:455) -- CONFIDENTIALITY NOTICE: This e-mail message, including any attachments,is for the sole use of the intended recipient(s), even if addressed incorrectly, and may contain confidential and privileged information.

Re: [JBoss-user] JBoss On Linux
Thanks for the info. I'll checkout the file descriptors. I didn't realize that could be the problem. I've had problems with them in the past, but its always been with non-java apps and the error messages were pretty clear.

Re: [JBoss-user] JBoss On Linux
The VM could be the source of my problem. My unix admin suspects that Sun's VM might not be handling socket connections properly.

The benchmark was designed to simulate the stress of 8 hours full server stress within 1 hour. Why do you think jboss crashed with the other VMs within 30mins? Certainly not because it was too slow. If it is too slow the only things you can see are error messages on the driver application injecting the benchmark-data to SPECjAppServer. It was the best test I can think of how well a VM (and of course JBoss ... since this was the thing I was testing) performs.

To diagnose this you might have to employ more than just one tool. netstat (comes with Linux/UNIX), filemon (http://www.sysinternals.com/linux/utilities/filemon.shtml) , Optimizeit (http://www.borland.com/optimizeit/optimizeit_profiler/), etc. Last, maybe there really isn't a leak, but the nature of your application, plus the crons that run at specific times, just simply require more file descriptors than what your system has configured. Upping that value might prove to be all you need to do. If it never grows past that max, you're set - no leak. Unfortunately, without doing some surfing, I can't tell you where to set it for your system, or what the best value should be. I'll leave that as an exercise for you. ;) Anyway, hope this helps. And sorry in advance if it ends up leading you down the wrong path. I just wanted to share what your problem smelled like to me.

Re: [JBoss-user] JBoss On Linux
Currently we deploy with hypersonic running but don't actually use it. Hopefully that should mean that it's not my problem. However, next week we will start using it as a persistent store for JbossMQ. The config i'm about to use is jdbc2 with pretty default settings. How does one run it "in-line" or "in-process"? I don't see a reference to that in the docs. thanks. .peter Jon Barnett wrote: On Fri, 2003-12-05 at 08:15, Peter Luttrell wrote: We're using JBoss3.2.1 with Jetty on RedHat 9 with Suns 1.4.2_01 vm.

Re: [JBoss-user] JBoss On Linux
I was very surprised to see that we had a problem getting a connection to the jndi service as well. I had assumed it was in-vm. We haven't modified conf/jndi.properties; we get our context manually. We set java.naming.provider.url to jnp://localhost:1099. I just noticed the following in the conf/jndi.properties file: # Do NOT uncomment this line as it causes in VM calls to go over RMI! #java.naming.provider.url=""> So it looks like setting it to jnp://localhost:1099 could really be adding to the socket load on the box, and thus we could be running out of file descriptors after a week or so, which is roughly how long we can stay running. Does this sound plausible? As far as stack size, our default is 8m. Does anyone have any recommendations on what we should set this too? Or suggestions on determining what is appropriate for our particular situation? thanks. .peter Adrian Brock wrote: On Thu, 2003-12-04 at 21:15, Peter Luttrell wrote: We're using JBoss3.2.1 with Jetty on RedHat 9 with Suns 1.4.2_01 vm.

Has anyone experienced similar problems? .peter This sounds like a problem with sockets. Beyond what John said about hsqldb, use "netstat -an" to see what sockets are open and what state they are in. But you should also check that the vm is responding at all and hasn't just hung. Use kill -3 jboss-pid to see whether it produces a thread dump. The most likely problem is your access to jndi. Why are you making it use a socket at all? It should be using in memory access. Either you have changed conf/jndi.properties (don't) or you have a jndi.properties deployed somewhere else with a provider url specified. jndi access should not be using a local socket inside jboss. Unrelated, you might also want to reduce the stack size. The typical 8M of stack is very large for java which allocates most stuff on the heap. Use ulimit -a to see your default setting. NOTE: There is a ulimit command in bin/run.sh where you should change this.

That's a pretty nice review. Does anyone else use JRocket on Linux? What are there experiences? .peter Christofer Dutz wrote: After testing a while with several VMs We found out that BEAs Jrockit is by far the best VM for usage with JBoss (Of course this is what we found out for our Tests and is only an oppinion, so please don't shout too loud). Even if it does cost a little for a production licence, the performance and stability it provides is worth much more. Using this VM we were able to run the SPECjAppServer2002 benchmark in a 9 Node cluster under full load for over one hour. This is much more than we could achieve with for example the Sun VM with 35min. This indicates that it seems to handle the usual VM-trash a lot better. We could even monitor absolutely constant Memory usage - a thing we could not say for the Sun VM. I would absolutely recomend trying this.

[JBoss-user] JMS Use: Multiple Server Versions?
We're considering the use of JMS with JBoss (JBossMQ). We're wondering if anyone has any ideas or opinions on this aspect: Our environment consists of multiple JBoss servers all with their own applications. We need to have a server app on one jboss server send and receive messages from a queue/topic on a different server; pretty simple to implement. We would also like to be able to upgrade jboss versions on different servers without needing to upgrade all the servers at once. I think this should work, but might depend on the protocol that the connection factories use. Should this even work? Is this possible at all? Is it only between major versions of jboss such as 2.x, 3.x, 3.2.x, etc? Do you have recommendations on what connection factories to use?

Title: Message I have a JMX MBean that access an entity bean via Remote interfaces. Is it possible to access the entity bean through Local interfaces instead? If so, how? Is there a place i define what to look them up by, such as the ejb-local-ref in either the web.xml or ejb-jar.xml? thanks. .peter
[JBoss-user] JBossCMP Change Column Names in CMR
How do you change the column names for a table generated by a MANY-to-MANY CMR? Here's an example of what i've tried: ejb-jar.xml: ejb-relation ejb-relation-nameUser-Roles/ejb-relation-name ejb-relationship-role ejb-relationship-role-nameUser-has-multiple-Roles/ejb-relationship-role-name multiplicityMany/multiplicity relationship-role-source ejb-nameUsers/ejb-name /relationship-role-source cmr-field cmr-field-nameroles/cmr-field-name cmr-field-typejava.util.Set/cmr-field-type /cmr-field /ejb-relationship-role ejb-relationship-role ejb-relationship-role-nameRole-Belongs-To-User/ejb-relationship-role-name multiplicityMany/multiplicity relationship-role-source ejb-nameRoles/ejb-name /relationship-role-source cmr-field cmr-field-nameusers/cmr-field-name cmr-field-typejava.util.Set/cmr-field-type /cmr-field /ejb-relationship-role /ejb-relation My understanding of how to do this is via this entry in jbosscmp-jdbc.xml: ejb-relation ejb-relation-nameUser-Roles/ejb-relation-name relation-table-mapping table-nameUser_Role/table-name /relation-table-mapping ejb-relationship-role ejb-relationship-role-nameRole-Belongs-To-User/ejb-relationship-role-name key-fields key-field field-nameusers/field-name column-nameuser_name/column-name /key-field /key-fields /ejb-relationship-role ejb-relationship-role ejb-relationship-role-nameUser-has-multiple-Roles/ejb-relationship-role-name key-fields key-field field-nameroles/field-name column-namerole_name/column-name /key-field /key-fields /ejb-relationship-role /ejb-relation But the problem is that jboss complains ~ It doesn't seam to be able to locate the users or roles field-name's that i've declared.

[JBoss-user] Classloader Question
Title: Message Is the classpath isolated for separate ears? If the classpath is not isolated, does anyone have a recommended strategy for handling ears with different versions of the same jar? I just deployed 2ears with radically different versions of the struts jar in them. Depending on which one loaded first the opposite blew up with errors that appear to be related to version changes with struts. If i deploy the ears separately they work fine. I am using JBoss3.0.1rc1 with tomcat4.0.3. Is this possibly a bug? .peter

I have a secure webapp that uses form based authentication. After a successfull login I need to check a flag and then potentially forward to a special page where the user is forced to change their password. Does anybody know how to do this? thanks. ..peter ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
RE: [JBoss-user] (no subject)
Ya, I was thinking about using such an approach, but I didn't like the idea of adding a check to every page (or even a static included header page). Sounds like it's unavoidable though. thanks. ..peter -Original Message- From: Damon Torgerson [mailto:[EMAIL PROTECTED]] Sent: Monday, June 10, 2002 7:00 PM To: [EMAIL PROTECTED] Subject: Re: [JBoss-user] (no subject) Peter If you're using JSPs a good example can be found in Advanced Java Server Pages by Geary. He uses a custom tag to check a session attribute and if the attribute is missing/wrong it forwards the browser to a page. You include the tag on all of the pages you wish to be secure.

RE: [JBoss-user] (no subject)
ya, it was a bit vague... I'm using declarative security for my webapp. I'm using form based authentication and I have a standard login page that posts to j_security_check. I need to administratively force the user to change their password on next login. I was hoping to handle this by writing my own implementation of the servlet that handles the j_security_check request. It would check the for a flag and forward on to a different page to force the password reset and once complete forward on to the originally request destination. I couldn't find any info about how to do this in the jboss or tomcat docs, hence the post. Then I realized that a user could get around the forced password change if they changed the url, which lead me to believe that I need to put a check on the top of every page, which i didn't really like. But it sounds unavoidable (based on the other reply). thanks. ..peter -Original Message- From: Starsinic, Frank [mailto:[EMAIL PROTECTED]] Sent: Monday, June 10, 2002 7:01 PM To: '[EMAIL PROTECTED]' Subject: RE: [JBoss-user] (no subject) i think you need to be more specific but i've done this in several applications. to redirect the user you can do ... response.sendRedirect(http://whoosywhasa.com/a.jsp;); i think this is what you're looking for. if not, let me know. frank -Original Message- From: Peter Luttrell [mailto:[EMAIL PROTECTED]] Sent: Monday, June 10, 2002 4:34 PM To: [EMAIL PROTECTED] Subject: [JBoss-user] (no subject) I have a secure webapp that uses form based authentication.

RE: [JBoss-user] (no subject)
yep, I would see it as unavoidable, unless you want to re-implement the login process yourself. I would write a filter that performed the check and have that do the redirection. Make sure you dont do a db-query every time though! Just use some flag in the session to indicate that the user has changed their password. ya, that's what I planned to do. thanks for the warning though. hth dim thanks for the info. thanks. .peter ___ Don't miss the 2002 Sprint PCS Application Developer's Conference August 25-28 in Las Vegas - http://devcon.sprintpcs.com/adp/index.cfm?source=osdntextlink ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
