Re: [JBoss-user] Memory Leak!!!
I've seen this type of error using only JSP Servlets. Others servers have same problem (A.F.A.I.K. there is a bug reported in JDC by WebLogic user). This problem is a memory leak of JDK, specially using Server HotSpot VM. Appear that WebLogic put a path in their product, so they doesn't solve the problems, but kick them to the future. Try using JBoss with -hotspot swtich, not -server (that is the default, correct???). If not, see: http://developer.java.sun.com/developer/bugParade/bugs/4466510.html http://developer.java.sun.com/developer/bugParade/bugs/4395735.html http://developer.java.sun.com/developer/bugParade/bugs/4390238.html Good luck!

[JBoss-user] virtual hosts
Hi, can someone tell me how to configure JBoss (Tomcat) to handle virtual hosts? I've found the server.xml file in tomcat's conf directory. However, I was unable to use it. I wanted to configure tomcat to handle the URL "http://127.0.0.1/" as it were "http://127.0.0.1/myJ2EEApp/index.html" (this latter is a J2EE app running in JBoss). Here's what I added to server.xml: Host name="127.0.0.1" Context path="" docBase="work/localhost_8080%2FmyJ2EEApp" / /Host It did not help, of course. Only the compiled JSPs are in the directory denoted by "docBase", so it cannot work this way. So how to specify virtual hosts that are backed by a J2EE app?

[JBoss-user] Question on Transaction Rollback Error
I have limited EJB experience and I am not sure if this is a design problem or a configuration problem. I have a Stateful Session bean which when loaded into JBoss can be accessed successfully from my test client. I then created a java class (Not an EJB) which is instantiated within the above Stateful bean and the methods of which are called from the above mentioned bean. Whenever a call is made to class I get the TRANSACTION ROLLBACK ERROR even if the method contains no body!! The bean is set for CMP but I dont do anything with transactioning I am not sure if I need to add the external class to some special config file to allow it to be used by my session beans. I read somewhere that beans accessing other beans should be specified in the XML file This is a strange problem fo rme and your help would be appreciated.

[JBoss-user] Redux of Performance Issues
For reasons unknown, this message hasn't been going out to the list. Trying again. -- Okay, I've clearly managed to piss off a few people by my concerns about JBoss performance. Let me start out by saying that I'd be more than happy to get my application working speedily under JBoss. Orion's documentation is poor at best, and JBoss is fully open-source. I have a great deal of respect for some of JBoss's technology (the verifier and deployer are probably the best I've seen), and where it's coming from. I chose JBoss for the initial development because of its reputation and my own interests. That said, if the performance I'm getting out of JBoss is the best I can expect, or, at least, the best I can manage to get, then I absolutely cannot use it. Not because I think it 'sucks rocks', because it doesn't, but simply because it will not support the user load I need it to in any sort of cost-effective manner. Some of you would probably be just as happy to see me go somewhere else, from the tone of your emails, but I'd personally rather find a way to get the performance out of JBoss, for this or other projects. And, ultimately, it seems as if the performance I'm asking for is relatively reasonable. I expect a certain amount of overhead in EJB performance, and I'm not asking to duplicate the speed of a bean-only implementation. But supporting a maximum of 25 concurrent users on a decent (if not maxed-out) server seems ... suspiciously slow. It may be that I've missed some settings to speed things up. It may be that our application's architecture is better suited to Orion than to JBoss. Whatever it is, I'd like to find out. So I've joined the JBoss list, and I'm here to ask some questions. I'm not trying to promote Orion, or insult JBoss. I like bits of both of them, and the reasons for that, I can get into another day. Ultimately, however, I'd rather support JBoss as an open-source appserver, if I can. -- Now, on to the details. Some of you pointed out, and rightly so, that I hadn't provided much in the way of details of what I've tried, which is true. I wanted to start off by finding out if the kind of numbers I was talking about seemed realistic or not, based on the experience of people who'd spent more time with JBoss than I have, but it's probably fair to say that you couldn't really say without knowing a lot more about my application. So let's get into a few details. Let's start with versions. I did some of my original EJB experimentation on JBoss-2.4.1. We started developing a project on JBoss-2.4.1a w/ Embedded Tomcat, which was the latest JBoss/Tomcat grouping at the time. We started noticing performance concerns then. When Tomcat 4 came out, we moved to JBoss-2.4.3 w/ Embedded Catalina, so that we could try a few things, and found it not to be slower, so we stayed with it. After we reached a point where we needed to see better performance, we did some optimizing of our app with a profiler, and tried JBoss 2.4.3 w/ Resin, which we already knew to be fast. That gave us a minor speed boost, but not very much, leading me to believe that JBoss might be the cause of some of our performance. By comparison, Orion 1.5.2 seems to be very much faster. All of this is running on Windows 2000. The versions of Tomcat are 3.2.3 and 4.0, as far as I know. The version of Resin is the latest version as of a few weeks ago, I'd have to go check. If it's important, I will. Processor speed depended, but developers are working, largely, on PIII-700MHzs, and we did most of our load-testing on a Ghz P4. Tuned updates are on, jaws debug is off, and logging was set as low as we really could expect it to be. Our performance numbers were derived in several ways - by using the Microsoft Web Application Stress tool (since we've used that in the past, and haven't yet found a better alternative; if you have suggestions, I'm happy to hear them), watching memory/processor load on the box being tested, junit test times and subjective experience. Our initial concerns came out of JUnit test times. Our EJB tests (which are pretty thorough, I'll admit) are taking several seconds, whereas the time required to test a hand-rolled bean solution was usually well, well under a second. HttpUnit tests are taking tens of seconds, instead of seconds. This began to concern me, but we didn't need performance at an early stage, and I knew I could replace Tomcat and/or JBoss if necessary. Once we started to use the Web Application Stress Tool, though, we started to get really concerned. After some profiling to speed a few things up, we were unable to get more than about 20 simultaneous users on the application without slowing things down significantly, getting Time To Last Byte on some of the more intense pages up past ten seconds, which is far too long. Even running Resin and JBoss together was getting us only up to 25. The processor usage on the server while the load test was running was practically solid at

When I start the server, I get the following error: [EmbeddedTomcatServiceSX] Starting [Configuration] java.lang.NoSuchFieldError: category [Configuration] at org.jboss.tomcat.EmbeddedTomcatServiceSX.startService(EmbeddedTomcatServiceSX.java:74) [Configuration] at org.jboss.util.ServiceMBeanSupport.start(ServiceMBeanSupport.java:107) [Configuration] at java.lang.reflect.Method.invoke(Native Method) [Configuration] at com.sun.management.jmx.MBeanServerImpl.invoke(MBeanServerImpl.java:1628) [Configuration] at com.sun.management.jmx.MBeanServerImpl.invoke(MBeanServerImpl.java:1523) [Configuration] at org.jboss.configuration.ConfigurationService$ServiceProxy.invoke(ConfigurationService.java:836) [Configuration] at $Proxy0.start(Unknown Source) [Configuration] at org.jboss.util.ServiceControl.start(ServiceControl.java:81) [Configuration] at java.lang.reflect.Method.invoke(Native Method) [Configuration] at com.sun.management.jmx.MBeanServerImpl.invoke(MBeanServerImpl.java:1628) [Configuration] at com.sun.management.jmx.MBeanServerImpl.invoke(MBeanServerImpl.java:1523) [Configuration] at org.jboss.Main.init(Main.java:221) [Configuration] at org.jboss.Main$1.run(Main.java:127) [Configuration] at java.security.AccessController.doPrivileged(Native Method) [Configuration] at org.jboss.Main.main(Main.java:123) Can anybody tell me what this message means - and more importanly, how I can get rid of it?

RE: [JBoss-user] Redux of Performance Issues
Allright, I'm happy to hear that I'm probably running it not-optimized, and the 'factor of 10' would certainly make me a lot happier, if that's what's happening. Some prelimary changes indicate that you're probably right. There's a significant decrease in processor load already, and at the moment, Tomcat is definitely holding JBoss back. We're probably going to give Jetty a shot in the short term, and find out what, if anything, we can do about getting Tomcat to handle the load. So, it looks like packaging was indeed the problem. Where that leaves us, we don't yet know. We'll do some tests and see what the results are, but the JBoss performance leapt from just plain silly to uh, let's see what we can do about tomcat in short order, so it's immediately promising.

Can you try again with cvs version? Yesterday a problem with not finding .zips in the classpath element was fixed. If you don't want to build jboss yourself, try renaming the zip to a jar and changing the classpath reference. Also, there's an example in ch 3 of the manual.
