We have an existing C++ application that we are going to gradually replace with a new Java-based system. Until we have completely reimplemented everything in Java we expect the C++ and Java to have to communicate with each other (RMI, SOAP, messaging, etc - we haven't decided). Now my manager thinks we'll need the Java and C++ sides to...
I have a web application using JPA and JTA with Spring. I would like to support both JBoss and Tomcat. When running on JBoss, I'd like to use JBoss' own TransactionManager, and when running on Tomcat, I'd like to use JOTM. I have both scenarios working, but I now find that I seem to need two separate Spring configurations for the two ca...
I'm writing a Resource Adaptor which does not support two phase commit. I know there is an optimization technique called: "Last Resource Optimization". On JBoss your XAResource class should implement LastResource in order to have the optimization. My question is: how this can be done in WebLogic, WebSpehre, Glassfish, etc... ...
I'm using a vendor API to obtain a JDBC connection to the application's database. The API works when running in the application server or when running in a stand-alone mode. I want to run a series of SQL statements in a single transaction. I'm fine with them occurring in the context of the JTA transaction if it exists. However, if it doe...
Does Geronimo provides a standalone transaction manager? And if it does, is it possible to use it in Tomcat? ...
I have a stateless bean resposible for persisting entities to a database. This stateless bean is called by a message bean's onMessage method. The wired thing is that on the first message everything works fine, but on the next message the method responsible for persisting is invoked outside a transaction, even though the method is annotat...
I'm analyzing the different behaviors between the JTA (Java Transactions API) and the .NET counterpart System.Transactions: the approach is quite different between the two of them. In fact, Java's version of Transactions seems more a specification, leaving to developers the obligation to implement either the Transactions, TransactionMana...
Basically, what it says on the tin; I need a JTA implementation useable in a J2SE application, ideally one that doesn't carry too much of a framework burden with it. ...
Suppose I want to implement an application container. Not a full-on JEE stack, but I need to provide access to JDBC resources and transactions to third party code that will be deployed in an application I'm writing. Suppose, further, that I'm looking at JBossTS for transactions. I'm not settled on it, but it seems to be the best fit f...
Looks like Bitronix, as suggested elsewhere, works very well. However, I'm stumped by a problem with it. I get this exception from Hibernate, when I attempt to save the session after I call TransactionManager.begin(): 14:21:32,350 ERROR [JTATransaction] Could not find UserTransaction in JNDI javax.naming.NameNotFoundException: Name Us...
Our application needs to use (read-only) a couple different persistence units pointing to different databases (different, commercial vendors as well). We do not have the budget to enable 2pc on one of them (Sybase). Is there a way to use these in a transaction without it having to be an XA transaction? We're using Websphere 6.1, Sybas...
Hi, Is it possible to make XA-transactional access to the file system in Java? I want to manipulate files within the boundaries of a transaction and my transaction must participate in a distributed transaction via JTA (so I guess the file system needs to be accesses as a XAResource). I don't need support for fine-grained read/write fil...
I am building a tool for out-of-container EJB testing. I have managed to run Hibernate's EntityManager in it successfully. Now I want to integrate it with JTA to enable strict control of transactions. The problem I am faced with is the following: Hibernate seems to require JNDI to work correctly with JBossTS (JBoss's JTA implementation)...
I am trying to integrate together JOTM and Hibernate EntityManager to test my EJBs in a transactional manner environment but out-of-container. My test looks like the following: Start JOTM Put JOTM's UserTransaction into JNDI Create and configure StandardXADataSource Put the DataSource into JNDI Configure hibernate and create EMF Creat...
I am working on a project with multiple JDBC data sources and JTA. I use Maven as a build tool, and I'd like to use the Jetty plugin (6.1.20) to run the application during development. I am trying to configure Jetty to use Atomikos as the transaction manager. I'm following the Atomikos documentation from Jetty, but the Jetty startup fai...
I'll try to describe the situation. We have a web service; on each request web service starts a JTA transaction. It performs several database calls through XA datasource within that and calls some other web services (out of transaction context) and also makes a couple of remote EJB calls on other server. The problem is that container s...
Hi! Is there a way one EntityManager can participate smoothely in multiple concurrent transactions? Well, not that concurrent. Something like: Start tx 1 Do stuff in tx 1 Start tx 2 Do stuff in tx 2 Commit tx 2 Join tx 1 back Do stuff in tx 1 Commit tx 1 with steps followed one by one not overlapping. ...
Is there a way to get JTA transaction timeout value? UserTransaction interface has only setTransactionTimeout method. Is there a specific way of getting its value in WebLogic? ...
What is the simplest (preferably without any new table creation) way of running a database query which takes long time (at least several minutes) in Oracle DB? ...
I've the JBoss and Hibernate based system. And I need to process two long operations. Operations can be probably longer than transaction's timeout. It operations are persists many-many entities, in two different transactions. And if something goes wrong, during this operations, I should rollback all changes of the transactions. What's ...
