jPos Contractor and Code Reviewer

Hi Everyone,

I am in need of another set of eyes (evident be my previous post) to
do a code review as well as some upcoming development enhancements.

If you have experience with jPos and are interested in doing some
contract work with possibly a yearly support retainer I am interested
in talking to you.

You're welcome.

Andy's observation related the deploy order is a good one to always take
into account.

Andy,

Thanks for the suggestion, I have always named (except when I am
playing around) my nodes that way as I learned from you guys long ago
on that one.....

THANKS!!!

I missed that my channelnames were not matching. I thought that the
READY was using the (<ready>BAL_3.ready</ready> ) and not actually the
channelName (<channel-adaptor name='BE-BAL-3'
class="org.jpos.q2.iso.Channel Adaptor">). I aligned the two and ll is
well now.

I new it was something I was overlooking, thank you again!.

Johnny -

What about the way these deploy items are named/numbered?

Channel needs to load first, then mux, then mux pool.

In our configuration we go 10_xxx for channels, 20_xxx for Muxes and 25_xxx
for mux pool.

What about the channel names, is it "BAL_1" ? remember that the 'ready'
indicator is named after channelName+".ready", so in this case, the channel
has to be called "BAL_1.ready". Is that the case?

Alejandro,

My 3 muxes looks like this:

<mux class="org.jpos.q2.iso.QMUX" name="BAL_Mux_Primary">
<key>11</key>
<in>BAL_1.receive</in>
<out>BAL_1.send</out>
<ready>BAL_1.ready</ready>
<unhandled>BAL.unhandled</unha ndled>
</mux>

The only difference would be the names (PRIMARY,SECONDARY,ETC...) and

MUXPool.isConnected is implemented like this:

public boolean isConnected() {
for (int i=0; i<mux.length; i++)
if (mux[i].isConnected())
return true;
return false;
}

So you need to figure out why your children MUXes are returning false.

Hi guys,

I am attemping to use a MuxPool and must be missing a connection (in
my head) somewhere but I have been unable to isolate where. I think it
is just my understanding of the MuxPool and hopefully someone has
implemented one and can show me the light.

I have a channel coming in, passing the TXN to a TransactionManager,

NYC anyone?

a...@jpos.org (Alejandro Revilla) — Sun, 15 Nov 2009 22:34:28 UT

I'll be in NYC next week visiting the NYC jPOS Developers Group :) :)
Just kidding, no JDG, but any jPOS developer there? :)
I have a tight agenda but would love to say hi and have a beer, please email
or DM.

Excellent. Those are great news!

Alejandro,
I always do an update before I start changing jPos code. So, I was
actually working on r2793, which contains Mark's further change for
the dynamicPackager code.
Ciao,

Alejandro,
I'm running via Q2. I haven't checked if the streams are open, but I'm
programming defensively. Other users of BaseChannel might be calling
clone() after connecting a channel. My code avoids any problems.

BTW, my server connections are now blazingly fast, so this was
definitely the problem. I also checked for other clone() methods in

BTW, you using BaseChannel > r2792 ?
I've introduced a change there and we have specific serverInLock and
serverOutLock.
Please svn diff -r2791 BaseChannel.java to see them all.
