[JCA/JBoss] - Re: HELP:CMP entity beans accessing encrypted datasource
by achu.prav
Hi Adrian ,
As suggested by you I enabled the trace.
The summary of the trace log is below:
---------------------------------------------------------
javax.security.auth.login.LoginException: Failed to decode password: java.lang.NullPointerException
at org.jboss.resource.security.JaasSecurityDomainIdentityLoginModule.commit(JaasSecurityDomainIdentityLoginModule.java:130)
----------------------------------------------------------
>From a servlet I am able to access the encrypted datasource without problems.This problem happens only if the CMP entity bean accesses the datasource.
Is it failing due to any security restrictions on accessing server.password file ?
Please help.
Following is the entire error stack trace:

[JBoss Cache: Core Edition] - Problem using Non-JTA Transaction Manager
by mlamdin
We are seeking advice for sharing 2nd-level cache between cluster nodes using Tomcat, Spring, and Hibernate. If you have been successful doing this, we'd appreciate hearing from you.
We'd also appreciate learning about dead-ends we might avoid.
Our configuration:
-- Tomcat 6.0.14
-- Spring 2.0.4
-- Hibernate 3.2.5
-- Spring-supplied HibernateTransactionManager
-- JBoss Cache 1.4.1.SP9 (JBC)
Our experiences to date:
-- pessimistic locking and replication sync work well, except under
moderate load where we get ReplicationException's and missing
updates to the database.
-- async and invalidation_sync did not replicate our caches correctly
Specific questions we have:
Will it be possible to use JBC reliably using a non-JTA transaction manager such as HibernateTransactionManager?
If a JTA transaction manager should be used, which one would you recommend?
Thanks in advance for your help.

[Remoting] - Remoting 2.4.0.GA is now available
by ron.sigal＠jboss.com
JBossRemoting 2.4.0.GA is now available. This is a major incremental release, that resolves about 160 JIRA issues, including 76 bug fix issues and 28 feature issues. It is meant to be binary compatible with the previous major release, currently at 2.2.2.SP7, and configurably wire compatible with any release back to 1.4.3.GA.
Among the new features are:
- Support for multihome servers [JBREM-643]
- Safe to run with installed security manager [JBREM-934],[JBREM-977],[JBREM-978],
- Better support for IPv6 addresses [JBREM-864], [JBREM-865]
- Improved connection monitoring [JBREM-888], [JBREM-891]
- Server gets client address in invocations [JBREM-758]
- Support for server configuration by microcontainer injection [JBREM-63]
Support for multihome servers requires an extension of the InvokerLocator syntax. For example,
socket://multihome:6500/?homes=10.32.4.2!192.168.4.2
will create a server bound to 10.32.4.2 and 192.168.4.2.
The jboss-remoting.jar file is available at http://repository.jboss.com/jboss/remoting/
The complete distribution zip file is available at http://www.jboss.org/jbossremoting/downloads/ .
Feedback is welcome on the Remoting user forum: http://www.jboss.com/index.html?module=bb&op=viewforum&f=222.

[JBoss Cache: Core Edition] - Re: No transactionality in caches
by duncow
The comment above about making sure a transaction hasn't already started intrigues me.
We're using *pessimistic* locking, but we are also using Spring's HibernateTransactionManager (specifically, annotation-based declarative transaction management).
If we are not using HibernateTransactionManager to support optimistic locking, should we still be able to use HibernateTransactionManager with JBoss Cache in a clustered environment, for pessimistic locking? If JBoss Cache throws a ReplicationException, for example, shouldn't HibernateTransactionManager still roll back the transaction?
Because we are seeing ReplicationExceptions and cache inconsistency, even with pessimistic locking and replication sync, I am also wondering if we are on the wrong road entirely by attempting to use JBoss Cache without JTA, even with pessimistic locking.
We are running on
-- Tomcat 6.0.14
-- Spring 2.0.4
-- Hibernate 3.2.5
-- JBoss Cache 1.4.1.SP9
Thanks in advance for any insights.
