WTF? Re: [jboss-cvs] JBossAS SVN: r67638 - trunk/connector/src/main/org/jboss/resource/adapter/jms/inflow.
by Adrian Brock
Bill, JBossAS is an open source project.
What is this patch?
1) Why is the first time I see this change in a commit message?
There's absolutely no discussion about this change anywhere.
This is where you discuss changes to JCA:
http://www.jboss.com/index.html?module=bb&op=viewforum&f=165
BEFORE YOU COMMIT.
2) Where is the JBAS-XXXX for this so it appears in the release notes?
Why does the commit message relate to a patch to an old branch then
modify a development branch?
3) These changes are not documentated anywhere, including the
WIKI page for the activation config properties of the jms resource
adapter:
http://wiki.jboss.org/wiki/Wiki.jsp?page=ConfigJMSMessageListener
4) Where are the tests for this new behaviour?
Not tested == doesn't work
Not tested == even if it appeared to work, it will almost certainly
unwittingly get broken by somebody in the future
5) The main purpose of this change appears to be to screw up the
whitespace. Making it hard to understand what has been changed. :-)
Please fix the formatter in your ide. Or if you have to
reformat, do it in a (null) seperate commit so the real patch
is easy to understand.
The change seems to be to introduce new activation config properties.
I'll deal with each individually.
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/trunk/connector/src/ma...
This feedback should have been sought BEFORE COMMITTING.
a) transactionTimeout
This looks like a complete misunderstanding by Weston.
This should be coming from the method attributes in jboss.xml
http://jira.jboss.com/jira/browse/JBAS-3321
b) isSameRMOverrideValue
This isn't used anywhere except the activation spec?????
[ejort@warjort jms]$ grep -ri isSameRMOverride * | grep -v svn
inflow/JmsActivationSpec.java: private Boolean isSameRMOverrideValue;
inflow/JmsActivationSpec.java: public Boolean
getIsSameRMOverrideValue()
inflow/JmsActivationSpec.java: return isSameRMOverrideValue;
inflow/JmsActivationSpec.java: public void
setIsSameRMOverrideValue(Boolean isSameRMOverrideValue)
inflow/JmsActivationSpec.java: this.isSameRMOverrideValue =
isSameRMOverrideValue;
c) forceClearOnShutdown, et. al.
The idea looks good, but the implementation is rubbish.
It shows a fundamental misunderstooding on how the pool works.
The notification happens once for each session that ends
(and hence so does your loop).
In practice with the default config, it will leave
the loop after the first session ends (almost immediately) when in the
default config there are still 14 other sessions to go.
A 1 second default wait is also unrealistic. Many people have MDBs
that take longer than this to process something.
In fact, this should be the default behaviour (but with different
configuration). Nothing should wait forever! :-)
The defaults should be specified in conf/standardjboss.xml
and the ejb3 equivalent aop interceptors file such that
users can easily change them.
In future (and some of it for this change):
* Please discuss before committing
* Raise JBAS JIRA issues so the release notes are up-to-date
* At least update the WIKI to describe the new features
* Write some tests
* Don't play with whitespace in real commits

Interfere the .EntityManager actions in jboss
by Meir Yanovich
Hello all
We have very large application that use's extensively the EntityManager
methods (createNamedQuery, createQuery, find, merge)
Now to refractor all the instances will be a pain, my problem is
That I need to insert another check in the returned value and filter it
out
Can it be bone after the information send into the EntityManager?

Warning -- need to clean and rebuild AS trunk
by Brian Stansberry
I just committed a change to
org.jboss.ha.framework.interfaces.ClusterNode in trunk that results in
IncompatibleClassChangeError if you try to run the AS without doing a
"build clean" and "build" first. So, if you update AS trunk, do a clean
and rebuild.

Reorg of jbossas/projects/cluster
by Brian Stansberry
I've switched JBoss AS trunk to a 1.0.0.BETA1 of the jboss-ha-client.jar.
FYI for anyone who has a checkout of this code: as part of this, I
reorganized the modules in repos/jbossas/projects/cluster so the
ha-client project can be released independently from ha-server-api. I
can imagine more frequent releases of the former as simple things like
load balance policy impls change/get added, while ha-server-api should
be more stable.
New structure under repos/jbossas/projects/cluster:
build
-- trunk
---- pom.xml
ha-client
-- trunk
---- src, etc
---- pom.xml
ha-server-api
-- trunk
---- src, etc
---- pom.xml
Old structure was:
trunk
-- ha-client
---- src, etc
---- pom.xml
-- ha-server
---- src, etc
---- pom.xml
