[JBoss-user] Order of events with BMP
using JBoss 2.4.3 i don't think i'm clear with regard to the sequence of events with the creation of a BMP bean. as i understand the sequence of events: * client calls home.create(xxx); * server calls bean.ejbCreate(xxx). * implementation of ejbCreate(xxx) should insert a row into the database, and return an initialized copy of the primary key. when simply trying to create a bean, the server is generating an error message from ejbStore(). does the server call ejbStore() after ejbCreate()? and should that method do the work of actually putting the data for the bean into the database? can someone clearly describe the correct sequence of calls to the interface methods? thanks in advance --e-- ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
[JBoss-user] jdk1.4's gone final
More than a couple things in 1.4 look attractive to JBoss: 1) JDBC 3.0 includes all the javax.sql stuff built in, but much cooler is the new ability to retrieve database automatically generated keys. http://java.sun.com/j2se/1.4/docs/relnotes/features.html#jdbc Not sure, but this might make it easier for the Entity Container to get the primary key back on ejbCreate if/when the key was a sequence. 2) Take a look at the Reflection Performance improvements graph here: http://java.sun.com/j2se/1.4/performance.guide.html Again not sure, but this looks like it could really help JBoss performance with the Proxy layer to the EJBs.

[JBoss-user] Embedd tomcat Mapping failure...
Hi, I've been trying out JBoss-2.4.4-Tomcat-4.0.1. JBoss is great.. ;) I started it up using the run_with_catalina.sh script. Everything seems to load up fine. i.e. no exception traces or anything. Seems quite normal (I've included the log anyway But when I try to access http://127.0.0.1:8080 I get HTTP Status 500 - No Context configured to process this request and the following exception trace appears in the jboss terminal. If I individually startup Tomcat it loads up ok..but with the above script...I always get the following.. Very strange. Hope someone can help me out on this one...

[JBoss-user] Memory leak in Minerva DB Pool
I have noticed a memory leak in my JBoss Minerva pool and am
wondering if there is a known fix or work around. I have checked the manual,
the forum, and the newsgroups with little luck. Let me give you the
specifics:
I am running on Solaris8 on x86, JBoss-2.4.1 and Tomcat-3.2.3. I
have a pool with the following configuration in my jboss.jcml
mbean code=org.jboss.resource.ConnectionFactoryLoader

/mbean
I have a stateless session bean which contains the code snippet:
try {
InitialContext ic = new InitialContext();
DataSource ds = (DataSource)
ic.lookup(java:/minerva_jdbc_matrix);
Connection con = ds.getConnection();
con.close();
} catch (Exception e) {
}
I didn't include the con.close() in a finally, since the only way a
connection could be opened is by ds.getConnection() working, which means
that it would always get to con.close() if a connection had opened.
I hit this bean with a client that runs 250 concurrent request. I
notice that in about 5-8 hrs, the memory of the Java process crawls from
about 70M to 120M at which point it will starts to throw OutOfMemory errors
and I can never get a connection the database again. If I turn off the
client, and let the box's CPU get down to about 99% idle, the memory never
clears up. I am forced to restart my server.
I have tried this with two different databases and jdbc drivers
(hsql and ms sql) and have gotten similar results, so I don't think it is a
bug in the drivers.
Am I using the pools incorrectly? Is that a pool configuration
parameter that I should try?
Thanks in advance for any help or clues,

[JBoss-user] inner transactions
I have two session beans, a and b. Both are container managed transactions,
Requires transaction. I call a from the client, which presumably initiates
the transaction, and a calls b. Something happens in b, which then throws
an EJBException. It seems like this is initiating a rollback, since b is in
a's transaction. Is this the case? If it is, presumably there is no way to
continue in a at this point, since the transaction has been rolled back?

I didn't include the con.close() in a finally, since the only way a
connection could be opened is by ds.getConnection() working, which means
that it would always get to con.close() if a connection had opened.
I hit this bean with a client that runs 250 concurrent request. I
notice that in about 5-8 hrs, the memory of the Java process crawls from
about 70M to 120M at which point it will starts to throw OutOfMemory errors
and I can never get a connection the database again. If I turn off the
client, and let the box's CPU get down to about 99% idle, the memory never
clears up. I am forced to restart my server.
I have tried this with two different databases and jdbc drivers
(hsql and ms sql) and have gotten similar results, so I don't think it is a
bug in the drivers.
Am I using the pools incorrectly? Is that a pool configuration
parameter that I should try?
Thanks in advance for any help or clues,
Lucas McGregor, NovaLogic

Re: [JBoss-user] AS/400 JDBC Database connection pool
Hi, Perhaps you can post your experiences of using JBoss on an AS/400. There has been some interest on this list and in the forums. http://main.jboss.org I haven't seen anybody give any real feedback. Regards, Adrian From: Yong T.

Re: [JBoss-user] About deployment application on JBoss

But in Jboss, do I have to write jaws.xml, jboss.xml, web.xml by myself and use Ant to build the ear file? Could anyone tell me whether there is better way to do so? Thanks in advance! JBoss can normally deploy jars, ears, and I think wars (with an appropriate web container) without any jboss specific files. You need the jboss files only if the defaults are inappropriate for you. You may be able to get away with not having any jboss specific files by some of these tricks: setting DefaultDS to point to the database you want to use Changing StandardJaws and StandardJBoss to specify more appropriate defaults. If you still need to customize further, I recommend investigating xdoclet (on sourceforge) which can generate all the deployment descriptors for several app servers including JBoss and Weblogic (and including ejb-jar.xml) david jencks Regards -- Jia (Christine) Li 524N ICT Building Department of Computer Science University of Calgary ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

Hi, I've been trying out JBoss-2.4.4-Tomcat-4.0.1. JBoss is great.. ;) I started it up using the run_with_catalina.sh script. Everything seems to load up fine. i.e. no exception traces or anything. Seems quite normal (I've included the log anyway But when I try to access http://127.0.0.1:8080 I get HTTP Status 500 - No Context configured to process this request and the following exception trace appears in the jboss terminal.

Probably not very much, unless deploy-time becomes of an issue. I cannot imagine any run-time features that would require relfection. Or? Think it depends what you mean by reflection. If you are referring to the process of getting Method and constructor objects the I agree, but this seems to refer to the actual invoke method. This article that the invoke method is 20 (twenty) times faster in 1.4 than 1.3.1. There must be at least two invocations on any EJB call (Proxy and Container), and that would, in the past, have added a much larger overhead than a straight method call. Indeed, this is good news. Looking at the rest of the article, the claims it makes are quite impressive (and if realistic, would make a significant difference to JBoss performance, IMHO). They are (over 1.3.1): Servlets: +35% EJBs: +34% SPECjbb2000: +58% Anyone fancy trying some figures for JBoss? I'd agree on the impressiveness ;) We are going to stress test our servers, if there is any useful data, I'll publish them here. cheers! ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user
