[Persistence, JBoss/CMP, Hibernate, Database] - valid hibernate session from Dao

by jnl

hi All... I'm using hibernate 3.2.2ga, jboss 4.0.5.ga, jdk 1.5. I'm trying to run a stored proc (and a query) within my daoImpl class but it's throwing an "unknown connection2" error. The full stack is below. Searching around jboss, I found this site.... http://wiki.jboss.org/wiki/Wiki.jsp?page=IGetquotTryingToReturnAnUnknownC... but it states it's only a hibernate 2 issue. The code is being executed within a callback. I also tried without the callback. My daoImpl extends org.springframework.orm.hibernate3.support.HibernateDaoSupport. below is the code and stack. any help would be appreciated.. thanks in advance..jim public java.util.Set findVolunteers(final int transform, final java.lang.String queryString, int pageNumber, int pageSize, final java.lang.String firstName, final java.lang.String lastName, final java.lang.String phoneNumber, final java.lang.String status, final java.lang.Boolean requiresFollowUp) | { | | org.springframework.orm.hibernate3.HibernateCallback callback = new org.springframework.orm.hibernate3.HibernateCallback() | { | final java.util.Set volunteers = new java.util.HashSet(); | java.sql.PreparedStatement stmt = null; | java.sql.ResultSet rs = null; | org.dcri.recruit.VolunteerSearchObject searchObject = null; | | | public Object doInHibernate(org.hibernate.Session session) | throws org.hibernate.HibernateException | { | try { | | // Get the connection from hibernate | Connection conn = session.connection(); | stmt = conn.prepareStatement(query); | | | rs = stmt.executeQuery(); | | // Process the results | while (rs.next()) | { | ..... | } | } | catch (Exception e) { | e.printStackTrace(); | throw new java.lang.RuntimeException("Could not execute Volunteer search", e); | } | finally { | try { | rs.close(); | session.close(); | } | catch (Exception e) { | e.printStackTrace(); | } | try { | stmt.close(); | } | catch (Exception e) { | e.printStackTrace(); | } | } | | return volunteers; | } | }; | return (java.util.Set)this.getHibernateTemplate().execute(callback); | and the stack trace...there's more if that'll help... java.lang.IllegalStateException: Trying to return an unknown connection2! org.jboss.resource.adapter.jdbc.WrappedConnect | ion@798797 | at org.jboss.resource.connectionmanager.CachedConnectionManager.unregisterConnection(CachedConnectionManager.jav | a:342) | at org.jboss.resource.connectionmanager.TxConnectionManager$TxConnectionEventListener.connectionClosed(TxConnect | ionManager.java:606) | at org.jboss.resource.adapter.jdbc.BaseWrapperManagedConnection.closeHandle(BaseWrapperManagedConnection.java:26 | 6) | at org.jboss.resource.adapter.jdbc.WrappedConnection.close(WrappedConnection.java:129) | at org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider.closeConnection(LocalDataSourceConnectio | nProvider.java:95)java.lang.IllegalStateException: Trying to return an unknown connection2! org.jboss.resource.adapter.jdbc.WrappedConnect | ion@798797 | at org.jboss.resource.connectionmanager.CachedConnectionManager.unregisterConnection(CachedConnectionManager.jav | a:342) | at org.jboss.resource.connectionmanager.TxConnectionManager$TxConnectionEventListener.connectionClosed(TxConnect | ionManager.java:606) | at org.jboss.resource.adapter.jdbc.BaseWrapperManagedConnection.closeHandle(BaseWrapperManagedConnection.java:26 | 6) | at org.jboss.resource.adapter.jdbc.WrappedConnection.close(WrappedConnection.java:129) | at org.springframework.orm.hibernate3.LocalDataSourceConnectionProvider.closeConnection(LocalDataSourceConnectio | nProvider.java:95) | | | | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4106026#4106026 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4106026

[JBoss Seam] - Re: Seam 2.0 + JSF 1.2 + Tomcat 5.5

by krismcg

Thanks for the prompt reply! I was under the impression you no longer needed to install jboss embedded in Tomcat with Seam 2.0? I used the instructions located here: http://docs.jboss.com/seam/1.0.1.GA/reference/en/html/tutorial.html Is there another set I should use instead?

[JBoss Messaging] - Re: Running JBoss Messaging on JBoss AS 4.0.4 ?

by jhowell＠redhat.com

Yep, Madhu is correct. When running JBM with the AS 4.0.x, Jboss Messaging must run inside of a scoped classloader. 4.0.x has versions a libraries for remoting and aop that are not compatible with Jboss Messaging. JBM requires more up to date libraries. To keep these straight the app server and JBM have to be run in two different classloaders. I have heard of people running JBM 1.3 and 1.4 with 4.0.x, but you have to look at jbm 1.2 and use the scoped classloader defined in that version. Not sure I would recommend it, because it isn't common, which means that it's not tested.

I downloaded the most recent production 2.0.0.GA and the problem is still there. I checked the ResourceBundle class and there is not setter for bundleNames, the error is as follows: java.lang.IllegalArgumentException: no such setter method: org.jboss.seam.core.ResourceBundle.bundleNames Could you take a look and let me know the work-around?
