RE: [JBoss-dev] Jboss/David Vs. Sun/Goliath?
It's interesting, since I didn't think anyone in JBoss was bluffing.
Question, though: JBoss is free, right? Therefore, before Sun goes around with the
bravado, couldn't they have downloaded JBoss and run it against the compliance suite
to know if it would pass or not? It seems to me that, if anyone's bluffing, it's them.

I'll be waiting to catch the flotsam work if/when that happens. I'm sure a lot of us
minor players will.
Still, my question stands- Sun could have downloaded JBoss and tested it on their own,
couldn't they? Why make comments like we don't think they'll pass then?

Don't be too sure that there isn't a number of months of effort to pass the
conformance suite. There are lots of edge cases and areas of interpretation
when implementing from a spec. There are also stupid things in specs that
implementers chose to implement differently with just cause.
Certainly the bits that developers care about are compatible.
The issue may be more about putting in the effort to do marginally useful
changes just to pass the conformance suite when there are some beautiful 4.0
features to work on, but maybe both can get done if everyone submits a patch
or two...

RE: [JBoss-dev] Why are we using this bogus construct
This is the direction I usually do it in...I use an implementation much like this one
when I want good atomicity on event broadcasting without excessive synchronization.
Generally, on an event listener array or something, I will have small sync blocks
around the critical method calls for methods manipulating the array, then will do a
synchronized wrap around an array copy (with clone() or whatnot) so that I can then
send the events asynchronously and not worry about the event listener array changing.
I've never seen it done the backwards way like that, but I guess it might work.

This seems backwards to me. I usually do something like this:

HashMap clients = new HashMap();
public void someMethod()

m.put(dc, cq);

For the insert, you only get a quick synchronized around the add, and
on iteration you get a single copy in the synchronize. If the
iteration very small and quick, I sometimes put the entire iteration in
the synchronized block, but you need to be careful about open calls.

The unsynchronized clients HashMap is synchronized and copied when

not thread safe for the accesses and makes for very expensive updates.
Why isn't the HashMap simply synchronized and used without copying?

Subject: [JBoss-dev] Health monitoring
Everybody heathy?
If you operate a 24*7 production plant with a server like JBoss,
you shurely care about the health of your server. Now in theory
this is nearly trivial: we have JMX and friends.
Any kind of monitoring can be done with it, but do we do? Of course
a lot of aspects are application specific, and for the rest of it
you may like to pull myserver:8080/jmx-console.
I still have some - trivial - thoughts about what could be done on the
server side to faciliate things; and I post my thoughts here to
collect some of your opinions on this (you care about health, do you?).
1) Threadcount
For me this is more or less a linux problem, allthough I found
questionable things even on NT4. The problem is that the current
thread count reported by the JVM is garbage. The best thing i can think
of is traversing the threaddump and counting threads on the fly.
2) Thread usage
If you are not an expert on every single part of JBoss, it might be
a detectives work to find out where all those nice threads in the
threaddump come from.
This is even more criticall, as we migrate to centrally managed thread
pools, where its more easy to do it wrong (not naming them appropriate).
Thread creation (and even pooling) doesn't come at no cost. I think
it might be affordable to do some more bookkeeping (factory?)
about how and when and from which part of the system (stacktrace?)
threads get allocated. This information - if accessible via JMX - should
give you a warm feeling.
3) Memory usage
I don't understand much of the JVM heap structure but I know of tools
(e.g. JProbe) which which can provide you with information about each
and every living object on the heap. These tools do at least use the
JVM debugging API, I don't know if they need modified native classes
to do so. If you do know, please let me know.
4) History
The current JBoss measures for counting threads and memory usage don't
keep a history about thread usage in the past. With a monitoring tool
online all the time we could solve the problem on the client side.
It should be trivial to support this through a collection MBean on the
server side. The interesting part comes with the persitence of this
information? What to do after some crash (out of memory)?
Perhaps log4j is the solution? Or do you favor database storage?
(Even that could be done with log4j and appropriate Logger/Appender setup.
5) Caches, pools and such
I would prefer more control on caches, pools and containers. If everything
is done right (with SoftReferences?) we should not fear out of memory due
to bad configuration.
But as I noticed on this list these aspects are on the TODO for Matrix2
anyway.
Ok, just me 2c, curious about what you think,
Michael Bartmann

RE: [JBoss-dev] is x++ an atomic operation??
You know...something seemed odd about it, but I was going to go with it anyway...I'm
still pretty sure that an increment operation is not atomic, but I can't be sure.
Regardless, the example statement given in the original post was something like:
x = y++;
And I'm almost 100% certain that's not atomic, as the increment of y and assignment to
x are two separate operations.

Subject: Re: [JBoss-dev] is x++ an atomic operation??
The jguru article is not accurate.
Given the code:
public class Test {
public int testInc(int x) {
x++;
return x;
}
public int testAdd(int x) {
x = x + 1;
return x;
}
}
This produces the following byte-code:
Method Test()
0 aload_0
1 invokespecial #1 Method java.lang.Object()
4 return
Method int testInc(int)
0 iinc 1 1
3 iload_1
4 ireturn
Method int testAdd(int)
0 iload_1
1 iconst_1
2 iadd
3 istore_1
4 iload_1
5 ireturn
Note the single operation for the incrementor (iinc 1 1). I do not know if
this operation is atomic or not, but this invalidates the logic of the jguru
post.

RE: [JBoss-dev] Implementing a Resource Protection System?
Yeah...I wasn't suggesting that for a hosted environment with hog detections anyway, though. What I was trying to do was point out the limitations I'm aware of with standard APIs that are available. The current limitation I'm aware of is that you can see when memory's getting tight, but you cannot see why (this is, of course, not including the JNI options mentioned here), so the best you can do is to politely ask components to release memory or you can just throw the baby out with the bathwater by undeploying all loaded components and then redeploying them. My original intent was not to suggest we take that route, but to instead show that the idea of a memory monitor wasn't really feasible to begin with. I'm now recognizing the poor communication of that idea on my behalf by not starting off with I don't think it'll work and instead commenting on what worked for me in an environment far removed from the one in question. -Original Message- From: marc fleury [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 11, 2002 1:53 PM To: Jboss-Development@Lists.

Again, not being a good programmer, is a horrible fate in CS world, so I am slow and your guys might get to invocation flow-profiling and sandboxing before I do.

RE: [JBoss-dev] Implementing a Resource Protection System?
Interesting...I'll have to check that out. Honestly, though, it doesn't sound like much of a solution for something like JBoss or even most infrasructural items.

From what I know, one can use JVMPI hooks to do fine-grained memory monitoring (http://java.sun.com/j2se/1.3/docs/guide/jvmpi/jvmpi.html). But this would involve writing some C, JNI, helper Java classes to query your custom profiling library for collected info. Depending on how well you design your library and how many profiling events you end up collecting, this may substantially slow down the JVM (just imagine the fact that you would have to call into the library every time an object is allocated or deleted, yikes). Also, once you load your library, you cannot debug this jvm remotely or profile anything in it using the standard profiling tools. - Anatoly Akkerman Computer Science Dept.

RE: [JBoss-dev] Re: ejbCreatemethod
Oh, well then it looks like there might actually be something simple enough for me to cut my teeth on after all. Wonderful! I'd be happy to give this a shot during one of my Sunday coding sessions unless one of the more seasoned people on here would prefer to do it instead of waiting on me. -Original Message- From: Adrian Brock [mailto:[EMAIL PROTECTED]] Sent: Friday, January 11, 2002 12:11 PM To: [EMAIL PROTECTED] Subject: [JBoss-dev] Re: ejbCreatemethod Rhett Aultman wrote: It looked like something simple enough for even a rookie like me to handle, but then I also recall seeing a patch on Sourceforge that already addresses this issue.

[JBoss-dev] I'd really like to help, but...
At the risk of sounding like an absolute newbie (and inviting all sorts of nasty responses), I wanted to ask the people in here if maybe they could help get me pointed in the right direction. My employer is considering the use of JBoss as our EJB container, and I felt that this would be the ideal time to start my education in J2EE infrastructure that I was going to put off until graduate school. I also have wanted to be able to contribute meaningfully to an open source project for a while now, and JBoss is definitely one with sufficient momentum that I can be a contributor without fear of having to become the sole supporter/developer/maintainer. I'm no slouch with my Java programming (or, at least, I don't think I am), and I've even written container systems for some of my own development projects, so I think I may have the kind of mind that would be useful as a JBoss coder. I've also set up development environments on my Win2K and Sun machines at home that I refresh with the nightly snapshots. I'm pretty familiar with JBoss, I've read the docs, and I'm digging through the API documentation as needed. I'm starting to feel like I'm actually ready to contribute in some way. The thing is...I don't know exactly where I might be needed. I know that to get RW access to the CVS tree I have to first submit three patches that get accepted. Where can I go hunting for bugs to patch, though? Almost all of the bugs I saw on the JBoss Sourceforge page have patches in the patches section already or have been assigned to an active project member. Is there somewhere else that some fresh meat would be needed? I have noticed that there are failures and errors when the test suite is run. Are people needed to try and bring the RabbitHole alpha up to snuff with its test suite, or is test suite compliance the sole responsibility of the core development team? Like I said, I'm eager to join in, and I think I may have skills to contribute, but I just am unsure as to where I actually can help. Could one of the more seasoned project members maybe give me some ideas? Alternately, if you're pretty much full up on developers or just don't need another rookie, I'd be happy to hear it. At least I'd know I'm barking up the wrong tree. I eagerly await any advice/comments/flames. -- J.
