[JBoss-user] Handle.getEJBObject() bug in jboss 3.2.3 - fixed.
FYI,
Attached is a small patch which fixes the problem that I found earlier.
(See prior posts from me with the subject:Handle.getEJBObject().
This patch fixes the problem where a serialized handle to an stateful session
bean was being used to get back to the remote bean instance. This call, in
jboss 3.2.3 resulted in an extra reflock on the stateful bean, thus causing a problem
when the container went to passivate the bean (Unable to passivate blah blah).
Once again, this patch is for jboss 3.2.3.
Regards,
Russ

Re: [JBoss-user] Unable to passivate due to ctx lock
Marek,
You aren't perchance using Handle.getEJBObject() in your client app/webapp are you?
If so, search this mailing lists archive for my prior post about Handle.getEJBObject().
I think that there may be a new bug introduced in the 3.2 series that causes an
additional
extra ref lock on the stateful bean.
If you're not using that call, then there is likely a chance that some ivars of
your
session bean can't be serialized...

Russ Chan

After switching from 3.0.6 to 3.2.3 we experience warning messages in
our logfiles:
WARN [org.jboss.ejb.plugins.AbstractInstanceCache] Unable to passivate
due to ctx lock, id=127.0.0.1:1099:dq6o9s7q-x
This seems to be a problem to passivate (a stateful session?) bean.
Looking into the code, the context of the bean seems to be locked:
protected boolean canPassivate(EnterpriseContext ctx)
{
if (ctx.isLocked())
{
// The context is in the interceptor chain
return false;
}
...
Is there a way to discover what is holding the lock on the context? What
is the impact of that warning for our application?
Thanks,

[JBoss-user] How to change: jboss.bind.address
How do I change the jboss.bind.address Im using version 3.2.3 w/ Tomcat. I found this: Using 3.2.2 or greater use the --host switch. In 3.2.2 you must remove snmp-adapter.sar from your deploy or it will generate bind errors. Example: run.bat -c default --host localhost But, what if I have to different wepapps that I want to listen on two different IPs. Can I set this address in jboss-service.xml file with the Tomcat .sar?? Thanx in advance Russ
[JBoss-user] Re: Possible bug in Handle.getEJBObject() - Jboss 3.2.3
Hi Scott, As requested, I've added this issue and these emails to the existing bug 780746, however, I don't think that these bugs are quite exactly the same. The other user wasn't even using the Handle.getEJBObject() call, which appears to be the cause of my woes. Anyways, take a look at the info I added in there, and if you deem it necessary, I'll file a new bug. If you need anything else, just holler.

[JBoss-user] Re: Possible bug in Handle.getEJBObject() - Jboss 3.2.3
Some more info... This behaviour happens regardless of being in a transaction... If I run a jython (python in a java interpreter - useful for testing!) connecting to the jboss server, I get the Unable to passivate message as soon as I call handle.getEJBObject() from the remote client, and the passivation thread runs. The jboss management console just shows the statefulSessionInstanceCache for the stateful bean growing larger and larger as more instances of the stateful bean are created. The pool management works fine, however. Russ Russell Chan wrote: Hi, I've been wrestling with this problem for a little while.

[JBoss-user] Throwing exception question....
Hello All-
Using: jboss3.2.3-tomcat
I have a class that will throw a user defined exception.
My method:
public ArrayList getPersistableObjects (String className,
String keys) {
if(cachelessKeyValues.length()
MAX_NUMBER_OF_REQUESTS) {
throw new
MaxNumberOfRequestsException(Request exceeds maximum number of requests
( + MAX_NUMBER_OF_REQUESTS + ));
}else{
.do
my stuff
}
}
I am wrapping this class with an ejb. I want to force
my front end developers to use a try catch statement to catch this exception in
their jsps. I have the remote interface and the bean class itself
throwing the exception up the line.
BEAN CLASS:
public ArrayList getPersistableObjects(String className,
String keys) throws MaxNumberOfRequestsException{
return
Mule.getInstance().getPersistableObjects(className, keys);
}
INTERFACE:
public ArrayList getPersistableObjects (String className,
String keys) throws MaxNumberOfRequestsException, java.rmi.RemoteException;
Everything compiles and works fine except that when the jsp
compiles, it does not force you to catch MaxNumberOfRequestsException
Any ideas? Ive been banging my head all day
with this..
Russ
RE: [JBoss-user] Throwing exception question....
Right!but doesn't...
Here's what the jsp looks like..
%
InitialContext context = new InitialContext();
Object ref = context.lookup(ejb/FactoryBean);
FactoryHome factoryHome = (FactoryHome) PortableRemoteObject.narrow (
ref, FactoryHome.class);
Factory factory = factoryHome.create();
String ObjectString = 601645,601647,601649;
ArrayList list = new ArrayList();
list = factory.getPersistableObjects(com.shawmut.model.Address,
ObjectString);
%
This should not compile
The Factory interface and its corresponding bean implementation both
throw MaxRequestObjectsException...
Thanx-
Russ

You'll need:
public class MaxNumberOfRequestsException extends Exception rather than
extends RuntimeException
or whatever you are using to avoid declaring it as being thrown.
RuntimeExceptions and Errors do not need to be handled.

Re: [JBoss-user] Selecting large datasets using CMP
Thanks for you reply Eric. I suspected this was so, but was hoping for someone else to come up with a nice elegant solution for me. I want to take advantage of oracle cursors, so in this case, it looks like I have to use the raw jdbc.

Re: [JBoss-user] Selecting large datasets using CMP
Thanks Scott, I don't think this will help though. I need to ensure that the dataset hasn't changed during invocations of the call, and I don't think that using multiple calls to this query (to iterate through the WHOLE dataset) will guarantee that - even WITH a SELECT FOR UPDATE, as another insert or update may slip in while jboss is loading up the beans (read-ahead strategy or not). If the CMP engine used a scrollable cursor or something like that, it would be ideal. I suspect that I will have to use raw JDBC from a session bean like Eric has suggested.

[JBoss-user] Possible to dynamically change datasource information?
Hi, Is it possible to manipulate a datasource programmatically, to change the characteristics of a datasource on the fly? Here's what we'd like to do: There are occasions, where we need to swap out our normal database to a replicated database, and we'd like to do this as smoothly, and in as controlled a fashion as possible. (The main reason for this is to upgrade the database software with patches, and the like). Our production system needs to run uninterrupted. I was hoping that I would be able to change the jdbc url and connections settings via JMX, and tell jboss to flush the connection cache. Is this possible currently? Also, is it possible to get transactions to block? Once again, this would be to allow our DBA to do some quick fix, while the database is on hold and then release it. The catch is that we don't want to lose any transactions in the meantime. We'd like them to block up, wait for a connection before continuing. I had thought that maybe I could reduce the connection pool size programmatically to zero, then reset it back to normal once the db operation was done. Provided that I can do this, and we can turn the pools back on before the transactions time out, is this feasible? -- -- Russell Chan, --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

[JBoss-user] Stored procedures and session beans
Hi, I've looked through the documentation, but haven't really found an answer to my question yet, so I'll try here. I have a case where some legacy functionality is wrapped up in an oracle stored procedure. I have a session bean which needs to do some lookups/updated, call this stored procedure, and do further lookups/updates. The session bean is currently implemented using CMT. Is it possible to get the stored procedure to run in the same database connection as the transaction? (Otherwise, my data lookups could be skewed because of the stored proc). If so, how do I get the connection? I've managed to get a database connection inline but it is probably not part of the current transaction, so I'm worried about dirty reads.

[JBoss-user] Re: JBoss-user digest, Vol 1 #2508 - 10 msgs
I'm not sure that I see a difference between using straight SQL in the session bean versus finding the appropriate entity bean and querying it for the current inventory. The advantage to using the entity bean is, of course, the portability that you mention. I would think that two methods on the session bean - checkInventory and reserveInventory would do the trick. Each would look up the appropriate entity and query for available inventory and reserve would reduce inventory if available. They would both be marked as requiring a transaction. Assuming that transactions are deferred to the underlying database, separate servers should play nicely together. Using a transaction isolation level of repeatable read or serializable (ugh) would then keep the data consistent within each transaction. Ultimately, unless the entity bean is marked as read-only, writing SQL in the session bean to look up inventory vs. using the entity bean shouldn't make a difference wrt transactions. David [EMAIL PROTECTED] 06/21/02 11:54AM Thanks Marc for the reply. The issue with your solution is that the inventory checks are for different users than the where we are updating inventory. Each time an item is displayed on a page, the server checks inventory to see if it is still in stock. This is required because the data keeps changing. If the user wants the item then they will click add-to-cart and that process will lock the inventory, double check that there is still one available and reserve a copy all in one transaction. Lets say user A on one JBoss presses the add-to-cart button. The record is locked and checked to see if there is one. User B on a different JBoss requests a page that has the same item on it. The system selects back the value for user B. User A finishes the transaction and commits. User B finishes the transaction. JBoss does the safety check for User B, determines that the record has changed, and throws an exception. This may not seem very likely, but in my experience it can happen at high volume, especially as the DB starts slowing down because of a great many requests. Also keep in mind that there will probably be 100 User Bs to 1 User A. I think I have two options at this point. Make the User B queries lock the row so that all users wait in line for access and nobody gets an error. Or, make the inventory query from a session bean using SQL. I posted this to see if someone knew of a better solution that uses CMP so that code is portable. For now, I am going with the direct SQL option because it is fast. I have also made the User A requests lock the rows so they play nice with each other. From: Marc Zampetti [EMAIL PROTECTED] To: [EMAIL PROTECTED] Subject: Re: [JBoss-user] Trying to get outside a transaction Reply-To: [EMAIL PROTECTED] I think you are over-thinking the problem. All you need to do is have a Session Bean method that performs the inventory check, and mark the method as Requires Transaction (or Requires New). Then, when you check the inventory, reserve a copy at that time. Thus, the check is the reserve, and either it works, or it doesn't. If it works, you have the copy reserved, and it doesn't, you know that it is not avaiable, and can display the appropriate message to the user. The DB locking should ensure that multile jBoss servers can't be caught in a race condiction. On the db side, you would do something like this: begin tran update table, reduce inventory by 1 select info back that you need. commit transaction. The update will reduce the eventory, and hold a lock on the page or row (depending upon the db setup). Then your select will return the info you need to determine if the inventory was still available. If you are using an Entity Bean, then the ejbLoad should be called when the transaction starts. I'm not sure how jBoss does it, but you would want to set the isolation level to REPEATABLE_READ, which basically locks the db page or row with the select and holds it. In this case, you must make sure that the entity is releases quickly, otherwise you are holding locks in the database for a long time, which will grind your system to a halt. --- Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user --- Sponsored by: ThinkGeek at http://www.ThinkGeek.com/ ___ JBoss-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/jboss-user

[JBoss-user] Weird error in Jboss container
Hi all , i am using RedHat6.1 , jdk1.3 , postgresql7.0.1 and jBoss2.1 .
The weird error are :
I have deploy my ejb which included 3 entity and 1 session bean.
The session bean is facade to the entity bean.
When i run jboss container and called a method from session for
example SearchByLikeProjectTitle() in my pc , it will display records in
the database.
All the method is execute ok in my PC .
However when i try to execute the method in different PC , it did not
display correct records.
All the method is not execute correctly.If i call ejbcreate , it did
not display my any error , but the records is not display in the table.
And when i tried to use findByPrimaryKey() to find records which exists
in the database , it display ObjectNotFoundException error eventhough
the records exists in the table.
Anybody have any idea why i tried to run jboss in different PC , it
give me different results ?
Thanks.
public ArrayList searchByLikeProjectTitle(String projectitle) throws
RemoteException,FinderException{
ArrayList result = new ArrayList();
System.out.println(projectinfohome + projectinfohome);
Collection collection =
projectinfohome.findByLikeProjectName(projectitle);
System.out.println(size + collection.size());
Iterator iterator = collection.iterator();
while(iterator.hasNext()){
ProjectInfo projectinfo =
(ProjectInfo)javax.rmi.PortableRemoteObject.narrow(

Hi David ,
If i ignoring the exception , didn't the method will throw null

I have do a testing and found that because my session is stateless
bean , instance variable is not specific for all client.
If i change the session to stateful , the method will throw null
pointer exception.
Am I correct to said that ?
Thanks
David Jencks wrote:
Hi,
I doubt your code as reported is complete. From what you show us, the
object returned from getProjectInfoJB is never created.
The no exception is presumably from your trapping and ignoring the
FinderException when you look for your bean. I suspect what is happening
is that jboss is reusing the same session bean for your two calls, and
since ejb attributes don't get reset by the container, it still has the
reference to the first bean. The finder exception from looking for a
nonexistent bean skips the assignment of projectinfo, so you call the 2
bean getProjectInfoJB().

Do you know how to do it ? I am using postgresql7.0.1 database.

This means that you haven't successfully mapped the bean-local name, "java:comp/env/jdbc/PostgresDS" to the global name of the DataSource you want. However , when i called ejb create , the records is inserted in my table and did not give me any error. I think you'll find that they haven't been inserted in your table, but in someone else's. JBoss defaults to java:/DefaultDS in this situation, which is the bundled HypersonicSQL database by default. You need to check your jboss.xml to make sure the mapping is set up correctly.

Below is my jboss.jcml file :
Yep, there's no DefaultDS there. That's fine, but it leaves the question of
why you're getting the right DataSource.
Does your code say something like:
DataSource ds = (DataSource) new InitialContext().lookup("java:/PostgresDS");
by any chance?
If not, what does it say?

Yes, this is the correct way to obtain a connection from a pool. Whether
or not pooling is actually happening depends on the specific implementation
of DataSource that you obtain from JNDI. If you have bound in a Minerva
connection pool, then you have connection pooling.

It seems like you are retrieving more connection from the connection pool than returning to it. When the server runs out of connections, it will hang until connections become available again. After you are done with the connection that have retrieved from the connection pool, you must return it to the pool by calling connection.close().

Re: [JBoss-user] Explicit commit and rollback in EJB
Hi Dan , Thanks for your info. Out of topic , I am trying to MessageDriveBean ejb , below is the list question regarding MDB : 1) What is MDB ? 2) What is the purpose of MDB ? 3) In what way can i use MDB ? To communicate between ejb bean ? 4) How to setup MDB in jboss ? BTW , our Asian counterparts are very curious how jboss developers can develop such a good products. What incentives that you all achieved ? Where you all get capital from ? How you all doing it ? Thanks wt. danch wrote: Russell wrote: Hi Dan , Thanks for u info. Read document regarding transaction in javasoft.com and i found out that what i done it in CMP is wrong. BTW , can i know why i must set the fetching key as RequiresNew ?? That isn't a 'must', it just shortens the time that the sequence might be locked in the database. On the other hand, Oracle for one allows simultanious access to sequences from different transactions at the cost of potential 'holes' in the sequence. Postgres might do the same thing, but I'm not sure offhand. danch ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user ___ JBoss-user mailing list [EMAIL PROTECTED] http://lists.sourceforge.net/lists/listinfo/jboss-user
Re: [JBoss-user] How to Lookup a bean from another bean (separate jars)?
Hi alex , From accessing ejb bean from separate jar,you did not need to specify the ejblink tag.Maybe that is u problems. Specify ejb-link for accessing ejb bean in the same jar. I test to accessing ejb bean in separate jar using jboss without any problems.Furthermore in jboss , is very simple than other ejb container. Hope that help. wt alex zhanov wrote: Hello, I tried to follow instructions from jboss manual with no apparent success. One bean(A) points to and uses another bean(B), what is suppose to go into bean(A) under ejb-ref to make it to work at least deployed on the same machine? As in my case, the lookup always throws exception.
