RE: [JBoss-user] Virtual machine problems

[saroj kumar]

Hi There,

This bug can be found in JDC Bug database.

Are you using Struts? If yes then your JVM may crash due to
High no. of struts tags in JSP. THere is some 64k limit on method
Size of a servlet which if exceeded results in this error. 

Solution for this is to take out some Struts tags and replace with
Normal java scriptlet.

All this is applicable if you use Struts.

There are other possible cases which are listed in Bug Database.

Hey

It is

You

to the query, the current application has some services which will get

how can this be achieved?I have the paid docs, but from that what I

I am trying to call 1 method on a SLSB remotely. 
I am running the method call in a thread which are being created
In a loop.

If I create 40 threads then everything goes fine. But, the moment
I cross 45, I start getting this error:

RE: [JBoss-user] TRANSACTION ISOLATION and ORACLE

[saroj kumar]

In that case, these settings are not going to work.

Are you doing some "SELECT FOR UPDATE" in one method and trying to
Access the same thing in other method?

One Thing, Can you change the TX Attribute to "Requires" of second
method and
Try it once.

Yes, there is no such thing for Session Bean.

But, how are you accessing Entity Beans? You must be calling 
Them through Session Beans only.

Or, you are making JDBC Calls?

These are different ways to handle Transactions and bean life cycle.
Default Commit option is A. You can have a look at
JBOSS_HOME\server\default\
Conf\standardjboss.xml.

I use Commit Option B in this way:

Snippet from jboss.xml
--



http://www.jboss.org/j2ee/dtd/jboss_3_0.dtd";>


  false
  



Instance Per Transaction CMP 2.x
EntityBean

B

  

  



  


AddressTypeMaster
Instance Per Transaction CMP
2.x EntityBean
sdsdsdsd
dsdsdsdlcoal


  



May be you can try this.

This problem will not be due to thin driver. I use OCI to handle CLOB.

RE: [JBoss-user] TRANSACTION ISOLATION and ORACLE

[saroj kumar]

Hi Mark,

2 things come to my mind:

1) Try commit option B/C They solve Deadlock problems quite nicely.

2) Add READ COMMITED Isolation Level as shown here in oracle-service.xml



  
  

OracleDS




jdbc:oracle:thin:@youroraclehost:1521:yoursid
jdbc:oracle:oci8:@RPM-9I 
oracle.jdbc.driver.OracleDriver

SDSDS
SDSDSD
TRANSACTION_READ_COMMITTED
 
  
  




jboss.jca:service=RARDeployme
nt,name=JBoss LocalTransaction JDBC Wrapper

i'm doing this right now and just got it working today.  i have a single

webapp "/global" that will serve all our virtual host customers a set of

functionality.  i'm using jboss 3.x series with embedded tomcat 
front-ended with apache.

i just have a straight-up .war file right now, with no jboss-web file. 
 just a bunch of servlets/jsp's.  all i did was tell apache to pass all 
requests for "/global" to tomcat via the connector with the proper mount

command in httpd.conf.

i'm on my way out, but can send more detailed info tomorrow if you need
it.

hth,

RE: [JBoss-user] SQL Exception

[saroj kumar]

Hi Vassilis,

I think this post may be of your use:

http://p2p.wrox.com/archive/enterprise_java_beans/2002-09/1.asp


Oracle uses optimistic concurrency. As a consequence, even with a
setting of
TRANSACTION_SERIALIZABLE, Oracle does not detect serialization problems
until commit time. Hence the message :
java.sql.SQLException: ORA-08177: can't serialize access for
this 
transaction
Even if you use the TRANSACTION_SERIALIZABLE setting for an EJB, you may
receive exceptions or rollbacks in the EJB client if contention occurs
between clients for the same rows. To avoid these problems, make sure
that
the code in your client application catches and examines the SQL
exceptions,
and take you take the appropriate action to resolve the exceptions, such
as
restarting the transaction.

Hi all,

I am running an application (Session EJB) that adds some entries in an
OracleDB through entity beans.

When I execute only one client of me application, there is no problem at
all.

However when I execute 300 clients concurrently for the same application
a
message

"java.sql.SQLException: can't serialize access for this transaction"

appears.

Any help?

Thanks

Use this:

   

java:/OracleDS
Oracle9i

  false
false
   

It will stop JBOSS from trying to create and drop tables.

then that would burn my support incident :)

RE: [JBoss-user] log4j and jboss: where is log4j.properties?

[saroj kumar]

Hi,

Sorry for delayed reply.

You need to create a Category like :

   --- Your package hier.
 -- the level of logging you want to enable
  

Then you need to use either default appenders (Console and File) or
You can have your own. Refer to log4j.xml. 

If you want to get the LOG msg. in your FILE Appender then
You may have to change the "Threshold" value to your "Priority"
value,say, Debug.
And NEED to change "Append" to "true".

EXAMPLE:

 
  




HTH,
Saroj

Thanks first!

Yes, I noticed that in $JBOSS_HOME/server/default/conf, there is

application deployed in $JBOSS_HOME/server/default/deploy?

But my test application run correctly, just say nothing:-), not log to 
log/server.log. Here is some snippits of my code:

static Logger logger = Logger.getLogger(UserInfoBean.class.getName());
..
logger.debug( "UserInfoBean: entering ejbCreate");


You see, very simple.

It seemed that, my looger can not find jboss's log4j.xml. Must I use 
PropertyConfigrator to load log4j.xml? I don't think so. I just want to 
use the default one that jboss give me:-). But how to?

Any hints?

Thanks in advance!

RE: [JBoss-user] multi-threaded remote client

[saroj kumar]

Hi ,

1st Problem can be solved using Commit Option B/C. Refer to TX related
Stuff.

2nd Prob is due to the fact that you are iterating the CMR Collection
In a different TX. Error Message is explanatory.

Are you using TXNew Attribute in one of your methods? It may be due to
this.

Ex:

SLSB A.doSomething()  B.getX() 

A.doSomething() has TX Required And B.getX() has TX New and it returns 
You a CMR Collection.

Of Course, there may be other combinations as well.

Subject: [JBoss-user] multi-threaded remote client


Hi all.  I've been having problems with a multi-threaded remote client. 
  I'd like to have two threads on a client accessing JBoss remotely, 
possibly the same data at the same time.  When I do this naively and 
both clients try to access the same entities, JBoss throws one of two 
errors:

13:40:57,457 ERROR [BeanLock] Application deadlock detected: 
TransactionImpl:XidImpl [FormatId=257, 
GlobalId=misosoup.ICSI.Berkeley.EDU//19663, BranchQual=] has deadlock 
conditions.  Two or more transactions contending for same resources and 
each have locks eachother need.

or

13:43:09,470 ERROR [STDERR] 
javax.ejb.TransactionRolledbackLocalException: The iterator of a CMR 
collection may only be used within the transction in which it which it 
was created

In the first case, it seems like each thread is creating its own 
transaction and that these transactions are in contention.  In the 
second, it seems like both threads are triggering calls in the same 
transaction and that these are trying to iterate over the same CMR 
Collection.

I've tried using both the same remote object and different ones; both 
situations lead to the same result.

So the question is: how do I do multithreaded remote access from a 
client to avoid this?  Note that different clients don't have this 
problem, only mutlitple threads from the same client.

Thanks,

Beau Cronin

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

[saroj kumar]

Running EJB-QL without Container/EB

We need to consider few points.

1) If there is no container then how do we parse the XML?

2) If there are no Entity beans then how do you query? 

3) If Above points are sorted out then how do we achieve complex
joins/unions?

4) Moreover, In case of large projects, describing the schema in XML may
require some tools
Otherwise, the sheer sixe of DB will prevent users.

This becomes crucial if the changes to DB are quite frequent.

Anyway, would this be difficult to achieve?

RE: [JBoss-user] JBOSS-EJB HOT DEPLOYMENT PROBLEM

[saroj kumar]

It may be due to different class loader loading the same bean during 
Hot deployment.

When JBOSS Starts up, it will load all the beans using (IMHO, Not Sure)
Default classloader and anything which is re-deployed may be getting
Loaded using different class loader.

So, When you refer to the same bean again, it is a different object as
It is loaded by another class loader.

If you are storing the remote/local ref in some instance variable of
Servlet then also it is possible as the object you are trying to refer
no
Longer is same as it is reloaded by different class loader.

May be I am off the mark.

Hi,
I am using jboss 3.0.3 integrated with jetty web server.
I am getting following problem during devlepment of simple application.
1) I have developed a simple staless session bean and putted the .jar
file
in deploy directory. It works fine when i call it from the servlet but
once
I change anything thing in EJB and replace into the deploy directory, it
give following error when i call it from the same servlet.

During replacement of jar it is showing Bean deployed properly.  IS the
above problem is due to hot deployement becouse if i restart the server
then everything works fine and the changes in bean also get reflected.

2) I have created a application directory which basically contain the
jsp
file and servlet and placed it into the deploy directory.when i try to
invoke any of the component, the server doesn't get it and give error.
But
if I create the war file of that application and place into the the
deploy
directory, than it works fine. Is it necessary to creat war file to run
it.


pls respond to above mail as I need it urgently.

[JBoss-user] JBossMQ messages being lost after restart Solution 
Hello, 
I solved the JBossMQ message being lost after restart.  I 
was using '/' characters in my queue name, and also 
using file persistence. Apparently the two don't 
match.  JBoss almost gets it to work, for it escapes out the '/' characters for the directory for storing messages. 
I believe somewhere in the code it is not escaping the 
queue names. 
So, bottom line: 
If using JBossMQ and file persistence, DO NOT put '/' characters 
in your queue name.

Hi All,

This problem is resolved now.

We had a while loop which was checking for some boolean value. This
boolean
Was updated by worker threads.

This update is done in a synchronized method call by worker threads.

On Windows, There is no problem. But, On Linux and Solaris, it creates a
deadlock.

It is resolved by making the main thread sleep for some time. Now, it
works fine on
Win2k, Solaris and Linux.

I am looking forward to some good design practices on Worker Thread
examples.

you can generate threads anytime within a JBoss application.  Just
remember,
you lose any transaction or security context when you spawn the thread.

[JBoss-user] Strange Problem on Linux

[saroj kumar]

HI All,

I am facing  "Transaction Timeout " exception while running
the code on Redhat Linux 7.3/JDK1.4/JBOSS 3.0.3/Oracle9i.

Same code is working fine on Win2k/JBOSS 3.0.3/jdk1.4/Oracle9i.

Scenario is:

UI Layer makes a call to SLSB. This SLSB makes a call to another
SLSB which uses a class. This class spawns two threads
And one of these threads operates on Entity Bean using a Session Bean.
When we make 1st call, it works fine but 2nd time onwards same call 
fails with Exception "TX marked for rollback. Possibly timeout".

Any help would be more than welcome.

TIA,
Saroj

[JBoss-user] How do we specify Commit Options

[saroj kumar]

Hi All,

I would like to know how do we specify Commit Options.

I would like to use Commit Option B.

I see that in StandardJboss.xml has 

Instance Per Transaction CMP 2.x
EntityBean

As well as

Standard CMP 2.x EntityBean.

What is the different between them? 

If I don't specify anything like this in
Any of the xmls such as jboss.xml and jbosscmp-rdbms.xml then which one
is used?

TIA,

RE: [JBoss-user] RE: Io exception: Stream closed while using CLOB

[Saroj Kumar]

Hi Stephen,

I agree that Oracle Thin JDBC Drivers have a problem. But, JBossCMP 
Does not support Oracle CLOB as well(with OCI).

If we use BMP then using Oracle API or JDBC, it is possible to use CLOB.
But, if we use CMP then even OCI drivers are of no use.

I have tried OCI Drivers with CMP and it fails.

Now comes the Apparent GOOD NEWS...

I have made some changes in JDBCCreateEntityCommand and I am able to
persist
CLOB in Oralce using JbossCMP.

I am unable to read the data in the CMP for now. I am trying to figure a
way out.

Any ideas would be more than welcome.

I will keep updating the list.

Thanks,
Saroj

Saroj,

This simply does not work if you are using the Oracle "thin" JDBC  
drivers. There is no work around.

You need to install Oracle client software on your JBoss machine and  
use the "oci" drivers.
Previously, you mentioned that you are using Linux. If that is the  
case, then maybe you need to do
an Oracle install, just don't start it up. You need to be in a position

where the Oracle sqlplus tool
works.

RE: [JBoss-user] Stateful Session Bean problem (newbie?)

[Saroj Kumar]

I think you need to keep that Remote reference in session so that
You get that in another JSP.

Otherwise, you will get the different SFSB.

AFAIK, a stateful session bean means, for a client, it
is the same, in the 1st point, the loginCheck.jsp
create the Object, in the 2nd point, an other JSP try
to retrieves the object... I begin to see where does
the problem comes from. But how to do what I intend
to?

It's not the same HTTP request (2 different business
methods)

half a second because the JSP is being compiled ;)

thanks for the answer :)

Yeah, this seems to be a good idea.

2) Which domain they work in?

Hi,
I was wondering:
-1- JBoss seems to be free
-2- JBoss seems to be the most downloaded Application
Server
-3- JBoss seems to be the most used by developpers
-4- A part of these developpers seems to be involved
in
the development of the open source community
-5- These developers develop things, particularly
EJBs...

So, according to the number of developers. How many of
them have RE-developed an EJB?

My question is: How about add to JBoss a Components
library (ie: a set of EJBs) that could be reused by
others? Imagine the time spent to RE-develop the same
things each time...

Waiting for replies... :)

Best regards to the JBoss and the Open Source

[JBoss-user] RE: Io exception: Stream closed while using CLOB

[Saroj Kumar]

Hi All,

I am trying to insert a CLOB column using CMP. CLOB data is 6028 chars.

I get the error "
java.sql.SQLException: Io exception: Stream closed"

I have been hunting the issue. It is JBOSS3.0.2 + Oracle 9I

It appears that JDBCCreateEntityCommand invokes
AbstractCMPFieldBridge.setInstanceParams. Method calls are

JDBCCreateEntityCommand.insertEntity() ---
**

// set the parameters
int index = 1;
for(Iterator iter = insertFields.iterator(); iter.hasNext(); ) {
JDBCFieldBridge field = (JDBCFieldBridge)iter.next();
index = field.setInstanceParameters(ps, index, ctx);
}

field.setInstanceParameters(ps, index, ctx) makes a call to
JDBCAbstractCMPFieldBridge.

JDBCAbstractCMPFieldBridge
**
JDBCAbstractCMPFieldBridge.setInstanceParameters() 
{
.
setArgumentParameters(ps, parameterIndex, instanceValue);
}

setArgumentParameters(ps, parameterIndex, instanceValue) makes a call to


JDBCUtil.setParameter(log, ps, parameterIndex++,
jdbcTypes[i],columnValue);

This sets the value in PreparedStatement and then 

rowsAffected = ps.executeUpdate(); is called in JDBCCreateEntityCommand.

Since inputStream is closed and ORACLE uses Streams to read/write
CLOB/BLOB it gives the error that
OutputStream is closed.

Any workaround???

NOTE: I tried to use getParameterMetaData for PreparedStatement but it
fails.
Oracle drivers are not implementing this JDBC3.0 feature.

Any idea for solving this CLOB issue would be more than welcome.

TIA,
Saroj

RE: [JBoss-user] Interrupted while requesting permit!

[Saroj Kumar]

I don't see any need for using finder Inside ejbCreate as JBOSS does it
automatically before insert.

It does like:

SELECT COUNT(*) FROM TABLE WHERE PK_COLUMN=?

Try without finder.

It looks like the mbean is registrated, but I get error message that

 I assume no 2 above is not correct.  But how should the URL be then?

Subject: [JBoss-user] Serious problem with wrong data returned.


We have a serious problem with JBoss 3.0.1 that I guess is not easy to
reproduce or else it should have been reported long time ago.  I post
here so that I can get help to identify where the problem really is.
My (BA devoted) collegue thinks it _is_ a problem with JBoss, but if
so, it should be corrected quite soon...

The following is a snapshot of a Cactus test:

public void testberegnSikkerhet() throws Exception{
final Collection c = ff.findAlleKunder();
for( final Iterator i = c.iterator(); i.hasNext(); ) {
final KundeLocal kunde = (KundeLocal) i.next();
cat.debug( "kunde.pk=" + kunde.getPrimaryKey() );
cat.debug( "kunde.foretaks=" + kunde.getForetaksnr() );
cat.debug( "kunde.data=" + kunde.getData() );
kunde.beregnSikkerhet( null, true );
}
}

The above getters are what is standard CMP 2.x and it is without doubt
wrong data that is written out:

   kunde.pk=[.1.]   kunde.foretaks=9
   kunde.pk=[.2.]   kunde.foretaks=9

In reality, the KUNDE table's FORETAKS should contain something very
different in both cases.  (FORETAKS is what was found in the last
entry of the table.)

Please help us to solve the problem.  (We use Oracle with
driver oracle.jdbc.driver.OracleDriver if it is interesting.)

This will break the ACID property no doubt.

This must certainly be one of reasons behind not having threads in

Wouldn't having multiple threads in a transaction break the ACID
principle anyway?

Particular the consistency and isolation parts.

Imagine the scenario:
Thread A reads object 1.
Thread B reads object 1.
Thread B updates object 1.
Thread A adds 1 to the value of object 1.

In this transaction the value of the object can be changed by thread B,
thus providing inconsistency to thread A.

Saroj,

You could try configuring your  settings in
ejb-jar.xml to be "Supports" for your entity bean "getters" and finders.
This should keep locks from happening as well.

Hi Dain,

The Problem is solved. But, I am not able to pinpoint the reason.

I just made a small change in my Oracle-Service.xml
To reflect the TX Isolation Level.

TRANSACTION_READ_COMMITTED

I did this change because of this reason :

StackTrace shows that
org.jboss.ejb.plugins.lock.QueuedPessimisticEJBLock class
Is waiting for TX Lock. I checked the ORACLE 9i for any lock but
could not find
any such lock.

QueuedPessimisticEJBLock gave me the idea that may be
Jboss is making the
ISOLATION LEVEL as SERIALIZABLE and thus trying to get a
EXCLUSIVE Lock whereas
Oracle is using READ COMMITED Lock and not allowing the
container to get the
EXCLUSIVE Lock.

This led me to add this line as per David Jencks's earlier mail( Thanks
a lot David).

Once I added this line, it worked fine.

Now comes the puzzling behaviour. I removed these lines again from
Oracle-service.xml to
Make sure that this was the cause of the problem.

But, Surprise!!! It was working fine. Still It is working fine without
this line in oracle-service.xml.

I am not able to understand this behaviour at all.

Anyway, it is working fine.

Thanks,
Saroj

Have you done a thread dump when it hangs?  Where is it waiting.  My

All jboss versions use the db default tx isolation level unless you set

AFAIK Oracle xa is the only db that disagrees with our code that sets tx

see
any such file in cvs.

RE: [JBoss-user] Specifying isolation level

[Saroj Kumar]

What is the default TX Isolation Level in JBOSS 3.0.1?

I noticed That Oracle-Xa and Postgres-xa service xmls in Jboss 3.0.2
have this but commented.

  


Other db-service.xmls are not having this entry.

Is it the case that Jboss will take TX Isolation Level supported by the
DB?

You could have a bunch of properties per connection factory and per
ejb-method that could be set just before a connection was enlisted in a
transaction for the first time.  Transaction isolation could be one of
these.  Weblogic does something like this.  I think it would be
ridiculously confusing because:

bean A, all methods tx required, specifying say READ_UNCOMMITTED

bean B, all methods tx required, specifying say SERIALIZABLE

method surprise on A calls doWork on B, isolation is READ_UNCOMMITTED

If you call doWork on B directly, you get isolation SERIALIZABLE

I think it would be hell to implement and maintain and provide
questionable
benefits at best.  Having another db pool with another isolation level
and
using it when you want the other isolation level seems simpler,
straightforward, and less apt to result in unpleasant surprises.

RE: [JBoss-user] home.findByPrimaryKey HANGS!!!!!!!!!!!!!!!!!!!!!!!!!

[Saroj Kumar]

Hi Dain,

The Problem is solved. But, I am not able to pinpoint the reason.

I just made a small change in my Oracle-Service.xml
To reflect the TX Isolation Level.

TRANSACTION_READ_COMMITTED

I did this change because of this reason :

StackTrace shows that
org.jboss.ejb.plugins.lock.QueuedPessimisticEJBLock class 
Is waiting for TX Lock. I checked the ORACLE 9i for any lock but
could not find 
any such lock.

QueuedPessimisticEJBLock gave me the idea that may be
Jboss is making the
ISOLATION LEVEL as SERIALIZABLE and thus trying to get a
EXCLUSIVE Lock whereas
Oracle is using READ COMMITED Lock and not allowing the
container to get the 
EXCLUSIVE Lock.

This led me to add this line as per David Jencks's earlier mail( Thanks
a lot David).

Once I added this line, it worked fine.

Now comes the puzzling behaviour. I removed these lines again from
Oracle-service.xml to
Make sure that this was the cause of the problem. 

But, Surprise!!! It was working fine. Still It is working fine without
this line in oracle-service.xml.

I am not able to understand this behaviour at all.

Anyway, it is working fine.

Thanks,
Saroj

Have you done a thread dump when it hangs?  Where is it waiting.  My

[JBoss-user] home.findByPrimaryKey HANGS!!!!!!!!!!!!!!!!!!!!!!!!!

[Saroj Kumar]

Hi!
  Ive been struggling with this for quite some time.I have some Jsps
deployed in 
  Tomcat 4.04 which then call EJB components hosted on Jboss 3.0.1.
  I have session and entity beans(CMP2.0) deployed on Jboss.
   
  My session beans calls a java class which in turn tries to do a
home.findByPrimaryKey on 
  an entity and hangs.When I do the same using a standalone java client
it works..but not
  through the Jsps hosted on Tomcat.

  Also setEntityContext is called and ejbActivate and EJBLoad are not
called.
  It just hangs and then times out after some time with the following
stack trace

[JBoss-user] Which one to upgrade to? 3.0.1 or 3.0.2

[Saroj Kumar]

Hi All,

We are faced with a dillema.

We are working on a big project which is having around 200 tables and
125 use cases. We have been using 3.0.0 but We found that 3.0.1 fixes
the Char Problem with ORACLE.

Now, 3.0.2 is also out.

We have to decide which one to use: 3.0.1 or 3.0.2. It is very important
that none of the code written for 3.0.0 breaks.

As we are a big team(20 members) and working on a very tight schedule,
it is very important for us to know which one is more stable. 

Please help me take the wise decision.

Thanks,
Saroj

Are you using JBoss 3.0.0?  If so, upgrade to JBoss 3.0.1.  Characters 
are now converted into strings before setting a parameter, because it 
breaks oracle.

[JBoss-user] How to handle NOT NULL Fields which have DEFAULT values in DB

[Saroj Kumar]

Hi All,

I have a scenario which I think is very common.

Some fields are defined as NOT NULL in DB but they do have DEFAULTS set.
If I don't include them in ejbCreate params then it fails to create any
Record. 

Is there a way to specify that this value is to be taken from DB
If not defined in ejbCreate.

How is this case handled? If I have to pass the value in ejbCreate()
Then I am unable to get the benefit of DB Defaults as I need to pass 
Them.

Any ideas??

TIA,
Saroj

I am using a Session Bean which makes call to the entity bean to
get a Chunk of Keys from the DB.

Session Bean runs in a Required TX and EB run is RequiresNew

complete the TX. It just hangs there.

  SequenceSession

Any pointers???

Did anyone use it successfully??

following.


  
Journal

  Required


What if I don't declare the   block for my
JOURNAL bean. What kind of 
TRANSACTION will be supported by the container? 

Is Default Value?? -

Supported

Because, I have seen that if bean is invoked under a Transaction even
then there is no problem.

Please help me understand this.

[JBoss-user] Strange Problem

[Saroj Kumar]

Hi All,

I faced a strange problem just now. Jboss3.0 + win2k + ORACLE9i + SSB +
CMP EB + classes12.zip

I have got a Session Bean which makes a call to an CMP Entity Bean to
Update the record. I pass some java.lang.Double Values 
To the Entity Bean from Session Bean. In Session Bean, We convert
BigDecimal Values in Double. If I  check for null
And set the value like this:

java.math.BigDecimal obj = issue.getAvgDaysInComposition();
  if (obj != null)
 {
 local.setAvgDaysInComposition( new
Double(obj.doubleValue()));
  
 }

Then it works fine and ejbStore completed successfully.

But, if I code like this:

local.setAvgDaysInRapidEdit( new Double(
issue.getAvgDaysInRapidEdit().doubleValue() ) );

Then ejbStore() does not complete and it HANGS!!!
issue.getAvgDaysInRapidEdit() is null and calling 
issue.getAvgDaysInRapidEdit().doubleValue() does not throw any NULL
POINTER but it waits indefinitely.

ANOTHER ISSUE: On Some m/c, even the NULL checked code hangs.

Any idea???

TIA,
Saroj

[JBoss-user] How is TRANSACTION handled (jboss 3.0 , ORACLE 9i)

[Saroj Kumar]

Hi,

I am puzzled by this sequence of events. Any hint??

I am having a session bean which is running under transaction. It calls
a 
JAVA Class. This java class makes 1st call to a Session Bean. This
session
 bean B invokes method on a Entity Bean. Then it invokes another Session

Bean C which makes Direct JDBC calls to DB for the data updated by
Session B
using Entity Bean. All this happens in one method which by the virtue of
being 
Invoked by a Session bean which is under a transaction also participates
in TX.

PROBLEM: JDBC calls show that there is no data INSERTED in earlier call
to Session
Bean B. SELECT for the inserted data does not return any row. It is as
if no insert is
Working.

Scenario is :

Session Bean A ---> Java Class --  Session Bean B --- Entity Bean EB1 ,
EB2
 +-- Session Bean C --- jdbc
call

PUZZLE:
I added some EJB finders on my CMP using ejb-ql and get the
correct data in the same
Method. Once this finder is called then all JDBC calls show correct
result.

Please note that Session Bean c gets its own SQLConnection from
javax.sql.DataSource.

Why is it so? I think that even if Session Bean C gets its own
connection, it should be 
Part of TX started in Session Bean A and should return correct result
for all the updates/INSERT
By Session Bean B.

Please help.

TIA,
Saroj

[JBoss-user] Is it a normal behaviour or Bug?

[Saroj Kumar]

Hi All,

We were trying to use "Block Sequence Generator" pattern as described in
Floyd's book.

It shows the ejb-jar.xml as this:



SequenceSession
*

Required


When we deploy the bean there is no prob. Once, We run the client, it
does not respond and hangs. 

But, if we modify the  as following then it works
FINE. We just removed * and coded
The method name.



SequenceSession
getNextNumberInSequence

Required


Is it a Normal Behaviour??? * should work just fine as it indicates
methods defined in HOME/Component Interface.

Any ideas?

TIA,
Saroj

Hi 
Edward,
 
I am 
having my xml in jar and need to read this once the bean is invoked in a 
DOM Tree. 
 
Code 
is :
 
 InputStream fi = 
this.getClass().getClassLoader().getResourceAsStream(xmlFile) ; // xmlfile 
is name of 
file   
InputStreamReader isr = new 
InputStreamReader(fi); 
InputSource is = new 
InputSource(isr);  
DOMParser parser = new DOMParser();  //  Parse the 
Document  //  and traverse the 
DOM  try {
 
 
parser.parse(is);
 
    }
catch(Exception e)
{
}

Hi All,

I have fixed this. 

Just made the method an instance method from static method and used.

InputStream fi =
this.getClass().getClassLoader().getResourceAsStream(xmlFile) ;

Then, I removed the DOCTYPE from the XML File and it works.

Hi,

I have no idea about Jboss-2.4.x. It is fine with Jboss 3.0.x.

It may have something to do with serialization of PK??/ (Just a wild

Hi,

   I am having the same problem.

   I am deploying the CMP bean that use composite key. I have no 
problem load and update the same bean.

   I have tried on both JBoss-2.4.7_Tomcat-4.0.4 and JBoss-2.4.8_Tomcat-
4.0.4 both throw the IllegalArgumentException when I attemp to invoke 
home.remove(key) from whithin a servlet.

   I wrote a jboss-client to test out the same bean, calling home.remove
(key). This time it doesn't any exception.

   I tried those (remove from servlet & remove from jboss-client) a few 
times, and the result are consistence. The servlet always throws 
exception and the jboss-client always no problem. I also try running 
jboss on Linux and NT server (using IBM JVM, hotspot1.3 and hotspot1.4) 
all give same result.

   The next thing I did was to download the JBoss-3.0.1_Tomcat-4.0.4 
and test my bean on it. I have no problem calling the remove on ny bean 
home interface.

   Has anybody ever try cmp + composite key + servlet + JBoss 2.4.x + 
Tomcat-4.0.4 with a successful result before?

   Can this be a bug for JBoss-2.4.x_Tomcat-4.0.4?

Cheers

[JBoss-user] When ejbCreate() is called

[Saroj Kumar]

Hi All,

I have a doubt about the time when ejbCreate() is called by JBOSS while
loading the beans. 

Is it the case that when bean is loaded in the memory, ejbCreate is
called or when any client looks up Home interface(ctx.lookup(JNDI Home)?


I understand that ejbCreate is called only if there is a need for new
instance and client has either called home.create()
Or remote.getXXX(). If free beans are there then no need for new
instance and hence no ejbCreate() is called.

Looking forward to your knowledge,
TIA,
Saroj

Thanks again,

But...What's the difference between :
1- Adding those 2 lines in the 'defaults' section of
'jbosscmp-jdbc.xml'
2- Adding the 2 same lines for each 'entity' of  'enterprise-beans'
section
I thought it should work in the same way, no ?

Title: Message



Hi Kamran, My reply was 
bumped off the server so I am 
resending it again 10 hours 
late.
Hi 
Kamran,
 
I 
would like to point out something regarding use of remove() method on 
EJBHome/EJBObject.
 
EJBObject : No need to use Handle here.  
I think that you are not using this method. It seems that you are 
calling EJBHome.remove();
 
EJBHomeObject: There are 2 ways to remove. 

 
    1) Use PK . home.remove(pk) - I 
generally use this or EJBObject.remove()
 
    
2) home.remove(handle) 
 
Observation: Mostly It looks fine to me except one 
small suggestion.
 
Suggestion: Instead of using this for EQUALS check , 
try the following :
    
 
    EXISTING CODE
    
**

    public boolean equals(Object 
obj) {    if 
(this.getClass().equals(obj.getClass())) 
{    
ApplicationPK that = (ApplicationPK) 
obj;    
return this.appID.intValue() == 
that.appID.intValue();    
}    return 
false;    }
 
    SUGGESTED CODE
    ***
    public boolean equals(Object 
obj) {  boolean 
retVal = false;
 
  if ( obj instanceof ApplicationPK 
)   {   ApplicationPK 
pk = (AddressPK) obj;
 
   retVal = this.appID.intValue() == pk.appID.intValue();  }  return 
retVal; }
 

    
EXISTING CODE
    
**

    public 
ApplicationPK() {    appID = new 
Integer(0);    }
    
SUGGESTED CODE
    **
    public ApplicationPK()
    {
    }
 
I 
think this should solve the problem.

Hi Sebastian,

No Need to remove "hsqldb-service.xml" from default/deploy directory.

Just add oracle service xml in deploy directory and add following to
your 

   
   
java:/OracleDS
Oracle8
   
   

To jbosscmp-jdbc.xml at top before  tag.

This should work.

[JBoss-user] How to ensure that Singleton class is not garbage collector

[Saroj Kumar]

Hi All,

I was just wondering under what circumstances a Singleton class is
garbage collected in JBOSS. How do we prevent it?

JDK1.2 + --> A class loaded by local/system classloader is not garbage
collected untill all the classes loaded by this classloader are
dereferenced.

How do we achieve this in JBOSS? Does it mean that all classes should be
part of 1 jar? I would like to have a jar which is having the class file
and classes in other jars to access it.

Any help is more than welcome.

TIA,
Saroj

On a seperate note, in addition to JXTA discussions on this list the
JXTA SIG 
of Bangalore, India would like to invite JBoss users and developers in
this 
region to attend this conference to discuss wonderful possibilities of a

possible marriage between JBoss (J2EE) and JXTA :-)

Please share this information with all whom it may be relevant.

This announcement is also available at http://jxtabang.linuxbee.com the 
website of JXTA Special Interest Group of Bangalore (JXTABANG) and at 
http://www.jxta.org, the official website of Project JXTA.

*Announcement***
P2P with JXTA.
An open architecture for peer-to-peer computing.

The JXTA Special Interest Group of Bangalore INDIA (JXTABANG) invites
you to 
the First Gathering in this region to discuss Peer-to-Peer computing
using 
JXTA protocols.
Tentative Date : Saturday, 7th September 2002
Tentative Venue: The Oberoi, MG Road. Bangalore. India. 

Background
The Information Technology as well as other sectors are going through a
rough 
weather. The time is right for solutions providers to innovate and stay
tuned 
with the emerging technologies. For business houses it is time to demand
cost 
effective alternatives through reduced infrastructure budgets and
maximized 
utilization of hardware resources.

Today's servers in enterprises are taking the pains of serving a large
number 
of clients during peak period while they idle during off-peak period
there by 
leading to inappropriate utilization of infrastructure. The client nodes
in 
the network are not fully active in providing the required resources to
other 
nodes when the need arise.

Peer-To-Peer (p2p) Computing paradigm is one such alternative to
maximize the 
ROI of enterprises. The p2p computing mostly addresses the discovery, 
publishing and communication channel between participating nodes may it
be a 
PC, a Portable Lap Top Computer or a hand held PDA.

According to industry analysts, the next big thing in the internet era
would 
be the p2p computing. Though not all the forecasts by the industry
analysts 
have been transformed into reality, there is a good chance that p2p
computing 
will compliment the other available architectures for internet.

Project JXTA, an initiative by Sun Microsystems, started as a research 
project with an open source model, has come a long way where ISVs have 
started integrating/developing their p2p applications using JXTA
Platform 
(Java Reference implementation)

RE: [JBoss-user] java.util.ConcurrentModificationException on XAPoolDataSource - need help...

[Saroj Kumar]

Hi David,

I do not have any idea about the exact reason for this error.

But, I feel that this may be one of the main reasons 

 Straight from Java API on HashMap 

The iterators returned by all of this class's "collection view methods"
are fail-fast: if the map is structurally modified at any time after the
iterator is created, in any way except through the iterator's own remove
or add methods, the iterator will throw a
ConcurrentModificationException. Thus, in the face of concurrent
modification, the iterator fails quickly and cleanly, rather than
risking arbitrary, non-deterministic behavior at an undetermined time in
the future. 


It will happen when collection is being modified after creating the
iterator.

[JBoss-user] Problem in looking up the Datasource thru a Standalone java class

[Saroj Kumar]

Hi All,

I am not able to lookup the DataSource in my standalone java class. I
get "request timed out exception".

Progr:

public class TestDS
{

public static void main(String[] args) throws Exception
{

String CONTEXT_PROVIDER_URL = "jnp://localhost:1099";
/* JNDI Context class Factory Name */
String CONTEXT_FACTORY_NAME =
"org.jnp.interfaces.NamingContextFactory";
String CONTEXT_FACTORY_PKGS =
"org.jboss.naming:org.jnp.interfaces";
/* JNDI Properties */
Properties Properties= new Properties ( ) ;
Properties.put ( "Context.PROVIDER_URL" , CONTEXT_PROVIDER_URL )
;
Properties.put ( "java.naming.provider.url" ,
CONTEXT_PROVIDER_URL ) ;
Properties.put ( "java.naming.factory.initial" ,
CONTEXT_FACTORY_NAME ) ;
Properties.put ( "java.naming.factory.url.pkgs"
,CONTEXT_FACTORY_PKGS ) ;

InitialContext initial = new InitialContext(Properties);

DataSource ds = (DataSource) initial.lookup("java:/OracleDS");
 

}
}   

Any idea why it is so?

TIA,
Saroj

[JBoss-user] CLOB Support in JBOSS 3 with ORACLE 9i

[Saroj Kumar]

Hi All,

I would like to know the support provided by JBOSS 3 for CLOB in ORALCE
9i. I am using CMP/CMR. 

It would be better if someone could explain the issues in detail. Any
help/hint/pointer would be more than welcome.

TIA,
Saroj

RE: [JBoss-user] Jboss 3 with ORACLE 8.0.5+

[Saroj Kumar]

Hi Igor,

Thanks for the detailed info.

I am using JBOSS 3 and it does not have any oracle-xa-service.xml in jca
dir. Is it a must to move to 3.0.1RC1?

I checked out the Bug Details as well. It seems to me that I need to
comment out a for loop in TxCapsule.java

//for (int i = 0; i < resourceCount; ++i)
+//{
+//   if (resourceSameRM[i] == -1 &&
xaRes.isSameRM(resources[i]))
+//   {
+//  // The xaRes is new. We register the xaRes with the
Xid
+//  // that the RM has previously seen from this
transaction,
+//  // and note that it has the same RM.
+//  startResource(addResource(xaRes, resourceXids[i],
i));
+//
+//  return true;
+//   }
+//}
 //}
 

Are there any other problems with using ORACLE? I am using Oracle9i. 

TIA,
Saroj

There are two possible ways to configure Oracle datasource (and two 
example config files in $JBOSS_HOME/docs/examples/jca).
As somebody has already mentioned on this list you could use 
oracle-service.xml as a starting point, set connectionUrl, 
username/password and drop the file into 
$JBOSS_HOME/server/default/deploy. This way you configure datasource for

local transactions only (for example, you cannot have a transaction that

includes both jms session and database connection). I would not 
recommend this configuration for production but it might be acceptible 
during development.
If you do need global transaction then you should go with 
oracle-xa-service.xml, however, configuration procedure is a bit more 
complicated and there is an outstanding compatibility issue that has to 
be resolved (see bug 585632 on SF). To configure xa datasource

Pre-requisites
1. Your oracle server must be java-enabled (if java is installed, 
following query returns non-zero result when executed from sqlplus
   select count(*) from all_objects where object_type like 'JAVA%';
2. JBoss 3.0.1RC1 (you probably need to checkout and compile Branch_3_0 
from cvs)
3. Bug 585632 is fixed. As a workaround you could try to use my patch 
for the bug, but it could cause problems with other non-oracle resource 
managers.

Configuration
1. Edit $JBOSS_HOME/server/default/conf/jboss-service.xml, find 
"jboss:service=XidFactory" mbean definition and add "true" to it. Mbean definition should look like

   
 true
   

2. Copy $JBOSS_HOME/docs/examples/jca/oracle-xa-service.xml to 
$JBOSS_HOME/server/default/deploy. Edit the file and remove 
"jboss:service=XidFactory" mbean from it. You should also configure 
database url, username and password.

Both xa and non-xa configurations require classes12.zip (oracle jdbc 
driver) to be put in $JBOSS_HOME/server/default/lib.

[JBoss-user] Jboss 3 with ORACLE 8.0.5+

[Saroj Kumar]

Hi All,

I want to know all the steps required to configure ORACLE 8+/8i/9i to
work with JBOSS3.

It would be better if someone could explain the pre-requisites and
necessary groundwork to be done to make it work.

TIA,
Saroj

[JBoss-user] Do Tomcat and Jboss share the same jvm?

[Saroj Kumar]

Hi All,

I would like to know whether Tomcat and Jboss share the same jvm or
different jvms. If they share the same jvm then my servlets can easily
make local calls otherwise I need to use Remote Interface for looking up
my beans.

Any light would be more than welcome.

You could use an mbean for that purpose which would have the additional
advantage of being reinitializable when you cycle your application and
configurable from any (RMI/HTML/whatever) JXM-Adapter.

Statics are poo-poo, IMHO.

Betreff: Re: [JBoss-user] How to register a class as a startup class in
JBOSS3


There is a generic way to do this with web applications in the 2.2 
servlet spec and even a better way in 2.3.

In 2.2, you can just have a servlet that calls your initializer in it's 
init() method.  Then, in web.xml, define the load-on-startup element. 
That way, when your web app comes up, you get called.  You can also call

a clean-up class in the servlet's destroy() method.

Now, in servlet 2.3, you can define a ServletContextListener (a servlet 
context is basically your web app) in the web.xml.  You will get 
notified via the contextInitialized and contextDestroyed methods.

Granted, each of these methods mean assumes you've got a web tier.  Even

if you don't, it's not a horrible thing to just through your ejb jars in

an ear along with a tiny war who's only job is to initialize some stuff.

Now, if you just wanted to now about startup/shutdown classes outside of

your app and specific to jboss, I don't know.

Hope this helps,
David

RE: [JBoss-user] How to register a class as a startup class in JBOSS3

[Saroj Kumar]

Yes, I agree that having a web tier which does all the work in init()
will do but what if I don't have any web tier and don't like to use a
servlet to do it.

I just need something equivalent to weblogic.system.startup.class="My
Class" kind of thing or any direct workaround without the use of
Servlet.

Thanks,
Saroj

I've reformatted the email a little because you seem to prefer top
posting. The words are all still there :)

Are you planning to restart that frequently? The singleton design
could still work quite nicely if you have a web tier and use (as
someone else suggested) one of your servlet's init() method to create
the instance. Naturally, this servlet would have to be loaded when
your app loads, but there's already support for this from the EJB
spec.

You get the advantage of "load on startup" without having to do
something clunky with your config files.

Yes, It is one of the way. Thanks for suggesting this alternative.

But, If we need to do some activity like File Reading/ Writing /Network

Why not just use a singleton to load and get the variables? That's how
I tend to handle situations like that.

[JBoss-user] How to register a class as a startup class in JBOSS3

[Saroj Kumar]

Hi All,

I want to register a class as startup class in JBOSS3. This class should
be loaded in memory when server is started. 

This class reads some properties and loads them in the memory. Other
classes need to access these variables using ClassName.Method Names().

Please suggest me a way.

[JBoss-user] Question regarding CMP and CMR Performance in EJB2 and JBOSS 3

[Saroj Kumar]

Hi All,

I have some doubts about the performance of CMP and CMR in EJB2 AND
JBOSS3.

Scenario is like this:

I have 1 bean called EMPLOYEE. It has got 1:N relationship with GROUPS
bean. This relationship is defined thru CMR.

I have a method on EMPLOYEE :

Public GroupModel[] getGroupModels()
{
// get all the groups
Collection groups = this.getGroups();

GroupModel[] arr= new GroupModel[groups.size()];

Iterator itr = groups.iterator();

Int i=0;
while(itr.hasNext())
{

Group g = (Group)itr.next();
arr[i] = g.getModel();
i++;
}

return arr;
}

So, First container will get the collection of EJBObjects for Group
bean. Then, it will start loading the beans one by one.

QUESTION is if the no. of records is high (100s) then will it not be
slow? If yes then is it better to go for Direct JBDC Calls instead of
using Beans for this purpose?

PLEASE HELP

Any real life experience is more than welcome.

Thanks,
Saroj
