RE: [JBoss-user] CMP tracing?

[Alan Yost]

Nathan - I'm not sure if this will help but we tend to change the log4j.xml file found 
in the conf directory.

Uncomment out the last few lines:-

  

  

This will then print out something very similar to the SQL statements.  e.g You will 
see WHERE XYZ=? rather than WHERE XYZ=22 etc.

Is there a way within JBoss to see exactly what SQL is being executed for a 
CMP bean as finder methods are executed?

Thanks

RE: [JBoss-user] Entity Bean Performance Tuning Help

[Alan Yost]

Georg - one thing that may help here is to create a LocalBean object outside of the 
loop and then set it each time in the loop as follows:-

  // The following for-loop is way too slow.
LocalBean localBean = null;
  for (Iterator beanIter = localBeanRefs; beanIter.hasNext();) {
localBean = (LocalBean)beanIter.next();
ValueObject valueObject = ValueObjectFactory.createValueObject(); //
...

This should reduce the overhead required in creating a localbean object each time.  In 
fact you may be able to do the same with ValueObject too.

Subject: RE: [JBoss-user] Entity Bean Performance Tuning Help



It seems that my (and, at least to some degree, Peter's) specific
problem is misunderstood.

In my case: the problem is NOT getting the data from the database fast
(the finders execute fast enough).
I think Jboss does not have a problem there, but that's my guess, as I
do not have personal experience
with other app servers.

The performance is lost, when I try to convert the a collection of local
entity bean references
into a collection of value objects. None of the previous posts (except
Peter's) touches upon this subject.

I want to understand and, if possible, solve this 'value object
conversion speed' problem:

  Collection localBeanRefs = localHome.findBySomeCriterion(...); <--
This is not the problem (good job, Dain) !!
  Collection valueObjects = new ArrayList();

  // The following for-loop is way too slow.
  for (Iterator beanIter = localBeanRefs; beanIter.hasNext();) {
LocalBean localBean = (LocalBean)beanIter.next();
ValueObject valueObject = ValueObjectFactory.createValueObject(); //
Same as new ValueObjectImpl();
valueObjects.add( localBean.buildValueObject( valueObject ) ); //
does: valueObject.setAttr1( getAttr1() ); ...
  }

The same using JDBC: 

  ResultSet rows = myJDBCWrapper.executeQuery( query, dataSource ); <--
Needs same amount of time as finder above.
  Collection valueObjects = new ArrayList();

  // This is at least 3 times faster than the for-loop above.
  while (rows.next()) {
ValueObject valueObject = ValueObjectFactory.createValueObject();
valueObject.buildFromRow( rows ); // valueObject.setAttr1(
rows.getString(...) ); etc.
valueObjects.add( valueObject );
  }

The for-loop should be able to convert 1000 local entity bean references
per second or better for simple entity beans.

I am not interested in any CMP vs non-CMP debate. TSS may be a better
place for this.

It would be convenient, if the size of the result sets, that can be
handled using CMP, coincides with the number of rows
you should/could reasonably display in a dialog or page in your
(web-based) GUI. This would remove the need to switch
to raw JDBC, when doing the CMP equivalent of plain vanilla (for
instance) "select * from BeanTable where lastUpdate >= '10/20/2002'"
queries. That's all I hope for. 

CMP will keep getting more powerful over time. Using it is 'Making the
trend work for you'.

Regards
Georg

Yes, in 4.0 there will be an abstraction layer between the cmp view of 
the world and the physical storage.  This means that it will be possible

to map several cmp beans in different applications to the same store.

[Alan Yost]

Adrian - thanks for the clarification of which JBoss versions this problem has been 
fixed in.  We have managed to code a work around for this as indicated below.  
Essentially, we are explicitly deleting the related child entities by cycling thru the 
related collection and applying the remove method.  i.e  We are manually performing 
the cascade delete at this stage.  When we do eventually upgrade to a version >=3.0.4 
we shall re-examine this area and see how we go.

Thanks again for your support

Alan.

Hello Alan,

The fix(es) are in 3.0.4 which has not yet been officially release.
But you can get it from CVS.

Try setting your cache size to something very small like 1. :-)
You should be able to reproduce the most likely cause of your
problem.

If 3.0.4 does not fix your problem, please feel free to open a bug report.

[JBoss-user] "removing bean lock and it has tx set" - revisited

[Alan Yost]

Guys - about a week ago there was a thread related to the subject matter above.

We still have a problem when attempting to delete an entity that has a 1:M 
relationship using CMR 2 and a cascade delete tag.

The error we receive whilst attempting to remove the parent entity is as follows:-

13:57:43,693 ERROR [LogInterceptor] TransactionRolledbackLocalException, causedBy:
java.lang.IllegalStateException: removing bean lock and it has tx set!
at 
org.jboss.ejb.plugins.lock.QueuedPessimisticEJBLock.removeRef(QueuedPessimisticEJBLock.java:473)
at org.jboss.ejb.BeanLockManager.removeLockRef(BeanLockManager.java:78)
at 
org.jboss.ejb.plugins.EntityLockInterceptor.invoke(EntityLockInterceptor.java:124)
at 
org.jboss.ejb.plugins.EntityCreationInterceptor.invoke(EntityCreationInterceptor.java:69)

We have checked the descriptors for the relationships and these appear to be the same 
as various examples regarding 1:M and cascade delete.  The cascade delete will work in 
the same JBoss session that the parent and child entities were created in, but will 
fail if the delete is attempted after a restart of JBoss.

We did note that in thread 
http://www.mail-archive.com/jboss-user@;lists.sourceforge.net/msg22239.html Adrian 
Brock indicated that he had resolved the matter after Alexey Yudichev offered some 
assistance.

If anyone could help us on this matter even we would very much appreciate it.  There 
are various indications that this problem has been resolved in a number of different 
JBoss versions - Is 3.0.2 one of them or is there a work around that we require?

Our Config:-
JBoss 3.0.2 
Windows 2000 server
MySQL 2.0.11-bin.jar  


Regards and thanks in advance

PS. If it helps I have included the original defect thread below...

We are getting a similar error (see below) from a Stateless Session bean using JBoss 
3.0.2.
We are also using the "Required" transaction attribute.  The error occurs after the 
following sequence of events:
1) create some data using entity beans, via a session facade
2) Shutdown JBoss
3) Restart JBoss
4) Remove the data using entity beans, via a session facade

Are we possibly doing something wrong or is this related to the same bug?

[JBoss-user] Entity Bean in a sar that depends upon mqSqlDS...

[Alan Yost]

Guys - I have battled thru a few dependency issues regarding ears and jars and sars, 
though this one I have left for a while but now is the time for me to resolve it.
 
If I deploy my two ears and a sar (man what language is this anyway :-)) once JBoss 
3.0.2 is running everything is ok.
 
However, if I restart JBoss with them in the deploy directory then I get a problem 
with the sar file.  The sar file includes an entity bean that persists some data 
associated with a timer that is also in the sar file.  
 
The entity bean persists to a mySQL database using CMP 2.0 and the problem I get is 
that the entity bean fails to deploy because it cannot find the data source 
java:/MySqlDS.  I suspect that this is getting loaded later and that I may be able to 
use some form of dependency tags to sort this out.  I just don't know if or where 
these tags should exist.  Or if there is some other standard way of resolving the 
problem.
 
I have started reading the paid for documentation but it looks like I have a lot of 
reading and I figured somebody in this group may be able to point me in the right 
direction.
 
 
Any help out there?
 
 
Regards and thanks in advance
 
 
Alan.

RE: [JBoss-user] eclipse with xdoclet and jboss

[Alan Yost]

Bruce - I had a similar problem to what you are describing yesterday.  In the end it 
turned out to be a problem with my paths in the build.xml.  I have been using JBuilder 
with Ant and recently migrated over to Eclipse and Ant.  I had to do quite a bit of 
rework to get the builds working.
 
What are your Classpath settings under the Ant preferences dialog? - You should have 
four classes that come with Eclipse (ant.jar, jakarta-ant-1.4.1-optional.jar, 
xmlParserAPIs.jar, xercesImpl.jar ) and the tools.jar from your JDK.
 
In addition, I found that I needed to add extra paths in the actual build.xml for 
xdoclet to work.
 
PS.  I think that Eclipse is a fantastic product considering it is free.  My first 4 
hours with it were miserable (with probs like you describe) but once you get passed 
these it is a great environment.
 
Regards
 
 
Alan.

Jonathan,  thanks. Tried that, still no luck. For some reason eclipse
doesn't use the same java.class.path variable that gets built by ant, (ie
picks up the system classpath setting), but uses it's own, which points to
a startup.jar.

RE: [JBoss-user] eclipse with xdoclet and jboss

[Alan Yost]

Guys - may I also add that you can set the xdoclet.lib.dir (xdoclet.home) and 
ant.lib.dir (ant.home) in your build.xml file with environment variables by using the 
following syntax:-
 




 
The key to everything is the first line of code.

I found this useful little tip in the xdoclet doco.  It works for Windows - not sure 
about other environments.  Very useful when working with other team members who have 
different paths to you.

One thing I forgot to add.  You do not need to bodge the eclipse
ant library to get it working.  The other way is to include the
ant jars in the xdoclet classpath, i.e. something like: -

[JBoss-user] RE: Are there any timer service changes between Jboss 3.0.0 and JBoss 3.0.1

[Alan Yost]

Ok - I have solved my own problem.  Turns out that I need to create and deploy a 
separate file jboss-timer-service.xml that contains the following code:-
 






















 









 

Thanks anyway

Subject: Are there any timer service changes between Jboss 3.0.0 and JBoss

I have an MBean that registers with the JBoss timer service to enable a 
polling facility that works fine with 3.0.0 but fails with 3.0.1. 
 
It seems that everytime I run the following code:-
 

Set lBeans = lServer.queryMBeans( new 
ObjectName("DefaultDomain","service","Timer" ), null );

if( !lBeans.isEmpty() ) ...



- the lBeans set is always empty.  

I have updated my jboss-service.xml file to include the following code:











and as indicated previously this works fine in 3.0.0.

 

If I look at the timer in http://localhost:8080/jmx-console it appears that 
the timer has started.  It's just that my MBean does not seem to be able to locate it 
anymore...

Does anyone have any idea what I may be missing, or if there is a subtle 
change that I am not aware of between 3.0.0 and .1 that is causing this problem?

 

Regards and thanks in advance

RE: [JBoss-user] MySql with Jboss 3.0.1

[Alan Yost]

David - I am working with Chris on this one.  I have just tested this and it works a 
treat.  I know that Chris (and I'm sure many others) have gone thru many painful 
experiences to get everything running (in 3.0.0) -coming up to speed with J2EE, 
XDoclet, Ant, JBoss, mySQL etc in the space of several months.  Sometimes we may not 
always look in the right place first time around - we apologise for this, maybe it's 
exhaustion, maybe oversight but thanks for coming up with the right answer so quickly. 
 We shall try to remember "the archives, the archives"

Alan.

Use the config file that comes with a release of jboss, or compare VERY
carefully, or look at the message that tells you what the problem is and
see if all the mbeans needed are actually there, or look at the mailing
list where this problem has been answered 20 or so times.

   jboss.security:name=JaasSecurityManager

needs to be

   jboss.security:service=JaasSecurityManager

in your mysql-service.xml

[Alan Yost]

Jon - Thanks for your reply.  Is there a work-around for this "bug"?
 
What do you do to get around it?  Is there any documentation that we can read that may 
assist in resolving this?
 
 
Thanks in advance

This typically happens during startup where it seems that JBoss reads
your bean jar file before it reads the data source definition.
Somehow this must be an bug in JBoss who should read all files in
server/xx/deploy in alphabetic order or some other deterministic
fashion.

RE: [JBoss-user] HELP : JBoss 3.0.x isn't logging ANYRuntimeExceptions!!

[Alan Yost]

James - I'm a relative newbie to EJB, but have used log4j in the past.  What I'm not 
sure of is how is the log4j first configured for my EJBs?   
 
In a normal java application I would include the 
PropertyConfigurator.configure(myConfigFile) statement in the main(String[] args) 
block at the start of my application.  This however, goes out the window with 
stateless session beans and Entity beans. 
 
I'm not sure as to how JBoss will maintain one instance of my Logger class.  Will my 
classes (even just plain old java classes that are called by a servlet etc) somehow 
use the same instance of the logger class that JBoss is using - and therefore I can 
use the log4J settings that come with JBoss, of do I need to include a separate 
configuration file and if so when would I initialise it?
 
Any help or words of wisdom would be appreciated.
 
 
Regards
 
 
Alan.

Uros - 
I've had a chance to look at the specified link below.  Got the timer bean

[JBoss-user] JMS Queues - Number per application/Limitations/best practices...

[Alan Yost]

Hello All,

Just a quick question (I hope)... We have an application with various components that 
are moving data from several different input/outputs.  We intend to do this with JBOSS 
3.0.1 queues.  This led several of out team member to ponder - what are the 
limitations of using Queues - i.e how many can you use.  We are looking at creating 
somewhere between 4-10 queues.  Is this excessive, or the norm, when moving data 
around between various sources/destinations?

TIA


Alan.

Alan,
I just finished reading EJB Design Patterns and found it to be very 
useful.  It has a whole chapter on building with ant, choosing package 
names, dividing up jar files, etc.  Nothing earth shattering, but good 
food for thought.  I used some of the suggestions verbatim and modified 
others and used them as ideas for my own situation.  I don't recall the 
author, but it is from a guy at The Middleware Company and one of the 
authors of theserverside.com.  That should be enough info for you to 
located it.

The book is well written and is high level architecture only.  I read 
the entire book in a few nights (it's small too).  It's the highest 
signal:noise ratio I've found yet for this topic.  It assumes you know 
how to code and just focuses on major architecture decisions.

I'm sure there is lot's of stuff on the web too, but I do enjoy having 
books as well.
gary.

[JBoss-user] EJB Design - Packaging / Components - how to?

[Alan Yost]

Hi All,
 
Just trying to work out the best structure for our "master build" file for an 
application that will have various components.  We have never done any large scale 
type J2EE work and I'm not sure how to best structure our ear,war and jar packages.  
How are others building their J2EE applications at present with multiple developers?  
Should we have multiple WAR, EAR files or a master EAR that includes all the rest?  
Can anyone recommend any good links/resources on this area?
 
 
tia

Hi

Please forgive me if this topic has been discussed before, but I couldn't find 
it in the forums.

I have followed through the instructions from Jboss site, and have has 
Petstore working nicely on JBoss 2.4.4. Today I downloaded Jboss 3 and tried to run 
the Petstore on it.

I made the relavent changed to DB configs into the new Jboss directories and 
deployed the ear and all seemed to go well. And I also get the page 
 fine.

But when I try to enter the store, it fails with the following message:

root cause :

java.lang.NullPointerException
at 
com.sun.j2ee.blueprints.petstore.control.web.ScreenFlowXmlDAO.getRequestMappings(ScreenFlowXmlDAO.java:249)

at 
com.sun.j2ee.blueprints.petstore.control.web.ScreenFlowXmlDAO.loadRequestMappings(ScreenFlowXmlDAO.java:115)

at 
com.sun.j2ee.blueprints.petstore.control.web.MainServlet.init(MainServlet.java:54)


investigation tells me this is due to the line MainServlet.java:54:

requestMappingsURL = 
getServletContext().getResource("/WEB-INF/xml/requestmappings.xml").toString();

Which returns:

14:15:41,234 INFO [STDOUT] requestMappingsURL = 
jndi:/localhost/estore/WEB-INF/xml/requestmappings.xml

And I think, in the new JBoss 3, this is not valid.

Has anyone come across this problem before? Am I missing anything?

Thanks a lot
Mak

RE: [JBoss-user] Deploying servlets (Java Tools for Extreme Programming example)

[Alan Yost]

It is deployed to the ..\jboss-3.0.0\server\default\deploy directory.  I have tried 
both hello.war and hello.ear. The book offers separate build/deploy options but 
nothing works.

I guess my main problem is that I am relatively new to EJB and JBoss etc and whilst 
the book examples have been very good, it has been geared towards Jboss and Resin, 
whereas I am using the vanilla JBoss3.0.0/Jetty configuration.

I am trying to also use the online-manual to enlighten me on application.xml - but I 
know that there have been various changes between JBoss 2.4.n and 3.n and therefore 
it's difficult to know whats right and wrong.  i.e How do I know which version the 
manual is refering to?

Werner - If you have any url links or advice that can enlighten me that would be 
great.  

PS.  Have you used this book?

Thanks in advance

[JBoss-user] Deploying servlets (Java Tools for Extreme Programming example)

[Alan Yost]

Hello All,

I am reading thru an excellent book called Java Tools for Extreme Programming 
(HighTower & Lesiecki) - Using JBoss 3.0.0 and Jetty.  I have followed the 
instructions but just cannot get the war file to display on a browser.
The file seems to deploy fine but when I try to access the servlet via a browser

e.g http://localhost:8080/hello/HelloWorldServlet

it returns an HTTP Error: 404.  I suspect it is a path problem but just cannot work it 
out.  Has anyone else out there experienced a similar problem with the examples in the 
book.


Regards and tia


Alan.

Hi David,
Thanks for your 2 cents :-) ...my actual question is WHY are there three
servers in the new distribution? There had to be a reason but I haven't
found any explanation. I imagine that they are each optimized for something
specific (thus my reference to server/all for clustering)...but what?

Can you shed some light?
Mary
