[JBossWS] - Web method memory leak?
by pophristov
Hello,
We have a web service for file upload/download. We are using a web method that returns a chunk of the file as a byte array for downloading. When the web service client downloads a large file the memory used by the java.exe (monitored using Windows Task Manager) swiftly increases and is never released. Eventually the used memory becomes so much that the whole computer performance decreases dramatically. Same happens if simply return a large byte array:
| @WebMethod
| public byte[] downloadChunk() {
| return new byte[524288];
| }
|
We are using JBoss 4.2.1 GA with JBossWS 2.0.1. Java 1.5.0_15. It is running on Windows Vista 32.
Any help on solving this will be greatly appreciated. Thank you in advance.
BP

[JCA/JBoss] - Configuring a non-JBoss JMS Provider (Weblogic) in JBoss?
by jferraro＠ihc.com
I am trying to configure access to a non-JBoss remote JMS Provider that I have to consume from JBoss. The JMS Provider is Weblogic and I am trying to subscribe to a JMS topic. On the JBoss side, I am using an EJB3 - MDB as the subscriber to the remote Weblogic topic. I am having difficulty configuring the Weblogic JMS Provider in JBoss. The JBoss configuration manual 7.4.3 Integrating non-JBoss JMS Providers is not very clear. I think my problem is around the QueueFactoryRef definition as I am trying to subscribe to a topic. I have tried to follow the Websphere JMS Provider example to some extent but that does not seem to work. I get the following error message (below) at JBoss startup. Under the error message are my configuration scripts. Might anyone have any ideas - I was directed to this forum from the JBoss Messaging forum as they believe this to be an integration issue?

[Security & JAAS/JBoss] - Problems with SPNEGO
by Antei
I have carefully read the manual (User Guide for JBoss Negotiation) and set up the test network for using SPNEGO:
- 1st host - Windows 2003 Adv Server (Active Directory and DNS)
- 2nd host - Windows 2003 Adv Server (jboss-4.2.2.GA with all needed modules and negotiation toolkit)
- 3rd host Windows XP (just for accessing from browser)
Then I tried to run Negotiation Toolkit. Results:
- Basic Negotiation - passed
- Security Domain Test - passed
- Secured - failed
Could you explain me what is the problem ?
Thanks in advance!
The stack trace on the JBoss was:

[Persistence, JBoss/CMP, Hibernate, Database] - Calling datasource.getConnection() after sessionContext.setR
by AlexFDT
Hello.
I am adapting an old application which worked on JBOSS 2.1 to the new JBOSS server version.
Now I am using JBOSS 5.0.0.Beta4.
There is a code in the application which acts like the following (simplified):
| javax.ejb.SessionContext sessionContext = ...;
| ...
| if (somethingGoesWrong()) {
| sessionContext.setRollbackOnly();
|
| //Then get connection to the DB
| javax.sql.DataSource dataSource = ....;
| java.sql.Connection con = dataSource.getConnection();
|
| //and execute a query
| ...
| }
|
The following exception is thrown when "dataSource.getConnection()" executes:
| org.jboss.util.NestedSQLException: Transaction is not active:
| tx=TransactionImple < ac, BasicAction: -3f57fffe:745:48918030:537 status: ActionStatus.ABORT_ONLY >;
| - nested throwable: (javax.resource.ResourceException: Transaction is not active:
| tx=TransactionImple < ac, BasicAction: -3f57fffe:745:48918030:537 status: ActionStatus.ABORT_ONLY >)
| at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:94)
|
Is it a JBOSS bug or such code really should not work?
I tried to debug using JBOSS sources. The exception is thrown from org.jboss.resource.connectionmanager.TxConnectionManager:
| public ConnectionListener getManagedConnection(Subject subject, ConnectionRequestInfo cri)
| throws ResourceException
| {
| Transaction trackByTransaction = null;
| try
| {
| Transaction tx = tm.getTransaction();
| if (tx != null && TxUtils.isActive(tx) == false)
| throw new ResourceException("Transaction is not active: tx=" + tx);
| ...
|
So if transaction is not in Status.STATUS_ACTIVE (TxUtils.isActive(tx)) then throw an exception.
Link to current source:
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/trunk/connector/src/ma...
Older version of this class used another check method:
| ...
| if (trackConnectionByTx && tm.getStatus() != Status.STATUS_NO_TRANSACTION)
| tx = tm.getTransaction();
| ...
|
Link to older source:
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/jbossas/trunk/connector/src/ma...
If transaction is not in Status.STATUS_NO_TRANSACTION then it is ok.
Older version of TxUtils.isActive(Transaction tx) was also functioning in the different way.
Old: TxUtils.isActive() returns true if the transaction is in Status.STATUS_ACTIVE or Status.STATUS_MARKED_ROLLBACK.
Current: TxUtils.isActive() returns true if the transaction is in Status.STATUS_ACTIVE.
All these changes were made corresponding to this issue: https://jira.jboss.org/jira/browse/JBAS-1916.
TxUtils.isActive() - it is ok. But I can not understand why TxConnectionManager changed to the way it works now.
If I did not read some documentation please direct me to it.
Thanks for all people who will answer something or even read this to the end. :)
