Debian is actually several Linux distro's: stable, unstable, and "bleeding edge". Their stable distro changes only when security problems (or bad bugs) are found, and those fixes are usually back-ported from newer versions of each package. In other words, you get bug fixes but not new features. You could do the same thing with JBoss - get the code using anonymous CVS and watch the changes. Port the ones that you're interested in over to your code base. Upgrade when you feel like it. ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

The quick answer is yes, you can do this, and you probably want to check
out EJBdoclet. It will create the primary key class (and a lot of the
other EJB code) for you.
http://sourceforge.net/projects/ejbdoclet/
Not to pick a nit but you *do* in fact have a primary key, it's just
composed of the two columns which together are unique, e.g.:
CREATE TABLE "text_data" (
"text_data" int4 NOT NULL,
"language" int4 NOT NULL,
"text" character varying(255),
PRIMARY KEY ("text_data", "language")
);
With this table you can have multiple rows for each text_data value and
multiple rows for each language value, but only one row for each
text-data/language pair.

Toby

Most HW vendors have "capacity planning" labs where you can borrow their high-end gear to run stress tests, but it's a good idea to run some preliminary tests in-house to resolve the obvious bottlenecks first. It's a fair amount of effort to do it right but you'll get lots of good data to feed back into your code.

I've noticed that jboss behaves differently than the Sun reference implementation, so instead of grabbing a Connection once and using it many times (e.g. the way Sun does it in their tutorial examples) you're better off getting and closing the Connection once for each method.

[JBoss-user] just curious: jboss/java/setiathome contention
Folks,
I had been fooling around with a small benchmark of my code (remote
client calls session bean calls entity bean, a little db i/o) and trying
to figure out why it was so darn slow (100 xactions in 70 seconds). I
stripped the code down to a simple round trip between the jboss server
and a client in another VM with little improvement but then killed
setiathome (which I had running "nice" in the background) and the
full-blown code (after I put back the database I/O) did 100 xactions in
15-16 seconds.
This is debian linux (potato), sun jdk 1.3.0, jboss 2.2 on a 1.2G athlon
with 256M memory. Everything's swimming, no swapping.
The solution is easy enough ("doctor it hurts when I do this" "don't do
that"), and therefore not terribly critical but I'm curious if anyone
knows why setiathome and java should have such a cat fight. I can't
remember any other application running any slower with seti in the
background.
TIA,

I can hack standardjboss.xml for a system-wide change or jboss.xml on a bean-by-bean basis. Nice. This raises an interesting issue, though: what the out-of-the-box defaults should be.

[JBoss-user] diff in behavior between server-side and client-side
Folks,
I just noticed the following behavior and wonder if there are preferred
patterns for dealing with it. I've got an entity bean which can
presumably be accessed by remote client-side code (e.g. in another VM)
or by session beans running in the jboss server VM. Let's say the
entity bean has some code like so:
private Money moola;
/**
* @remote-method
*/
Money getMoney() {
return moola;
}
I noticed that the remote client code gets a copy of moola but the
server-side session bean gets a reference to the member itself (and can
thus change it). This makes sense but it does mean that the behavior is
different for in-VM client code and remote client code. Is this
"standard" EJB behavior? One approach to trade some efficiency for
safety would be as follows:
Money getMoney() {
return new Money( moola);
}
This way the clients would be unable to modify the private member even
if they were running in the same VM. Are there other approaches?
TIA,
Toby Cabot

Re: [JBoss-user] jboss 2.0 connection pool AutoCommit default?
More data: AccountEJB.java from the Sun j2ee tutorial grabs a Connection in setEntityContext(), holds onto it until unsetEntityContext(), and uses it for all database work in the mean time. This doesn't seem to agree with the 1.1 spec (page 168) which shows example code grabbing and releasing the Connection in the same method. If I hack the code to grab and release in each method then it seems to work as expected. Guess I'll point this out to Sun.

Folks, Jboss is great! I'm getting my feet wet porting some of the Sun j2ee tutorial code (stateless session "Converter", BMP entity "Account") over to jboss 2.0 and postgresql 7.0. It's been pretty straightforward so far, except for one issue: it appears that the Sun BMP code assumes (and the Sun reference j2ee container implements) that jdbc connections are by default AutoCommit true, since the AccountEJB code never calls setAutoCommit() or commit(), but the results *are* committed to the database. In jboss/postgresql it looks like AutoCommit is false by default since I get the same behavior if I explicitly setAutoCommit( false) that I get if I do nothing (i.e. results never committed to db).
