[EJB 3.0] - How to get EntityManager on the fly for custom DB?Hi,

by artemgolubev

Hi, all! Our client wishes the next way of working for our application: On some user input (we have web application + EJB3), we must create new database from a template and use it in our EJB3 environment. I do not know how to implement it in JBoss :( Usually for single datasource we create -ds.xml file to create JDBC datasource and then reference it in our META-INF/persistence.xml file. But how I can create JDBC datasources on the fly and use it with (different) EntityManager-s on the fly? I appreciate any thoughts on this topic.

[Remoting] - Re: No connection possible after an illegitimate attempt

by tom.elrod＠jboss.com

The problem lies in our use of javax.net.ssl.SSLSocketFactory.getDefault() internally when explicit ssl config is missing (more on this in a min), which can be found within org.jboss.remoting.security.SSLSocketBuilder (line 421). The jdk (at least Sun's implementation) will cache this factory once created, including the system property values used to create it. Therefore, once a transporter client is created using ssl based transport, this default SSLSocketFactory is created and will be re-used for any other transporter clients created using a ssl based transport. Unfortunately, can't do much about jdk's default SSLSocketFactory not re-checking the system properties after it has been created once. However, will add to the remoting transporter client code so can pass in explicit ssl configuration, so don't have to rely on the default ssl socket factory (see http://jira.jboss.com/jira/browse/JBREM-652).

[JBoss Getting Started Documentation] - DB2 Database connection error

by maheshvanamula

I am currently facing the 'DB2 Database connectivitty' issue with the 'DB2' database. Trying to connect to the 'DB2 UDB iSeries V5R3', but it gives the error as org.jboss.util.NestedSQLException: Could not create connection; - nested throwable: (org.jboss.resource.JBossResourceException: Apparently wrong driver class specified for URL: class: com.ibm.as400.access.AS400JDBCDriver, url: jdbc:as400://3.11.96.3/GETSJDE); - am using a JSP page to test the connectivity. The first request to the database connection will not work. However, When i refresh the JSP and then the connection works fine. Please visit to the URL : http://:<port_number>/DB2ConnectionTest.jsp Let me know if you have any resolution. Here is the datasource details of the database. <no-tx-datasource> <jndi-name>DB2Pool</jndi-name> <connection-url>jdbc:as400://3.11.96.3/GETSJDE</connection-url> <driver-class>com.ibm.as400.access.AS400JDBCDriver</driver-class> <user-name>guest</user-name> </no-tx-datasource> Please provide the resolution.

by mzeijen

Thanks, that will really help :D. But an official list would be great. Is there any time to make on Gavin? Or do I need to create a Task in Jira?

[JBoss Seam] - Re: Can Seam work with no ejb3 but with Hibernate ORM?

by pgrillo

It all makes sense. We just don't have that much experience configuring/using JTA or even JNDI for that matter. The biggest reasons for that were simply a) we never had a specific need and b) wanted our apps to come quickly for our developers with minimum configuration requirements that may vary by environment (test or development). However, Using these technologies is probably long overdue, so i'll probably try switching to JBoss as our development app server (instead of Tomcat), and figure something out for Junit. thanks for the explanation.

[EJB/JBoss] - What's the default transaction attribute (trans-attribute) f

by wikijuarezjunior

Hello there, It seems to be a very simple question but it's being hard to find an accurate answer, though. What's the default transaction attribute (trans-attribute) for stateless session EJBs in JBoss 3.2.x series? I mean, if there's no trans-attribute what is default for JBoss 3.2.x? I've found this reply from Adrian Brock but at that time (2001) it stated that the "current" default value was REQUIRED. In summary, may someone please tell us the current (2006) default value for trans-attribute on JBoss 3.2.x? Thanks in advance!

[JBoss Seam] - Re: Can Seam work with no ejb3 but with Hibernate ORM?

by gavin.king＠jboss.com

Yes, Seam assumes JTA. Of course I could go off and implement my whole own tx management layer on top of JDBC, that looks exactly like JTA, except isn't - just like everyone used to do (Hibernate, JPA, Spring, ...) but of course this is totally fucking nuts! You now have this horrible combinatorial problem of all these different fwks each having their own tx API, causing nightmarish integration problems when if they all would have just used what already exists and works just perfectly well, there would be no problem! So at the moment I am refusing to contribute to making this problem worse, by not introducing my own tx abstraction. We use JTA, and thats it. You can use JBoss MC to get a lightweight JTA/JCA layer in any environment you like, just like the "jpa" and "hibernate2" examples do (type "ant deploy.tomcat"). But most environments (read everything except testng, junit and tomcat) already have JTA.
