Hi I have a seam pojo annotated as @PersistenceContext (type=EXTENDED) private EntityManager em; and I have the factory method @Factory ("foobar") @SuppressWarnings ("unchecked") public void findAllFoobars() { foobars = em.createQuery("from Foobar f").getResultList(); } When the factory method is called, the entity manager is null. Does anyone have any idea why this would occur? All my other objects based on EntityHome<> work fine. Oh yeah, I am using 1.1 CR1.

[JCA/JBoss] - Bug/Missing feature in XA-DS.xml

by jshrinivas

If max-pool-size is not specified and only min-pool-size is specified then max-pool-size should be set => min-pool-size whereas it defaults to 20 rendering min-pool-size setting of no use. I hope I am not missing something here.

[JBoss Seam] - Re: no value for request parameter: taskId

by juangiovanolli

i'm basing my example in the todo example of jboss seam. it's very simple, and is almost equals to that, but in's not working for any reason. the unique difference that i can found is that my app doesn´t include the login part of the todo example. Any ideas.

[EJB/JBoss] - ConnectionManager issue in Stateless bean and injected Entit

by kearns7153＠tds.net

I am getting the following INFO message from the ConnectionManager when accessed from a Stateless bean: 14:36:01,687 INFO [ConnectionManager] forcing batcher resource cleanup on transaction completion; forgot to close ScrollableResults/Iterator? The application looks like it is working so what does this mean? I am using JBoss 4.0.5 GA, but same issues exists with 4.0.4 GA. I am using Postgresql 8.1 for a database. I am using Seam, but this error occurs without invoking my UI client. @Stateless public class MyTrialBean implements MyTrailRemote { @PersistenceContext private EntityManager em; ... public String update(Biu biuAttributes) { try { String serialNumber = biuAttributes.getSerialNumber(); List bius = em.createNamedQuery("Biu.findBySerialNumber") .setParameter("serialNumber", serialNumber) .getResultList(); if ((bius == null) || (bius.size() == 0)) { return ProXmlResponse.getError(ProError.BIU_NOT_FOUND); } Biu biu = bius.get (0); biu.setLastContact(new Date()); em.merge(biu); } catch (Exception e) { return ProXmlResponse.getError(ProError.BIU_UPDATE_FAILED); } } ... Other posts/replies state that I should close the connection in a finally block. I have tried various calls to the EntityManager but those usually result in an error. I based most of what I am doing here on the EJB3 TrailBlazer demos. I am looking for more information on this problem to see if it is related to the following more serious ConnectionManager problem. 14:52:08,817 WARN [JDBCExceptionReporter] SQL Error: 0, SQLState: null 14:52:08,817 ERROR [JDBCExceptionReporter] No ManagedConnections available within configured blocking timeout ( 30000 [ms] ); - nested throwable: (javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] )) 14:52:08,817 ERROR [STDERR] Nov 30, 2006 2:52:08 PM checkStats INFO: PurgeStatsBean.checkStats()...Failed View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990196#3990196 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3990196

[Performance Tuning] - Re: Identifying performance bottlenecks

by jshrinivas

Analyzing thread stack traces indeed proved useful. Thanks for your help. I looked at http-0.0.0.0-# threads and most of them were in WAIT/BLOCKED state. All these threads seem to be waiting for JDBC connection. Basically it seems that they are waiting on org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection method. During this I also realized that JBoss XA JDBC pool config is not intelligent (or I might be missing something here). I had specified min-pool-size as 200 and did not specify max-pool-size and it defaulted to 20, which was strange. I am going to post this on JCA forum. Anyways, changing max-pool-size helped a bit and I was able to get another 5% CPU utilized due to that. I also found out that there was a bug report on org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection being slow. I am not sure if it is fixed in 4.0.5-SP1-ejb3. -Shrinivas View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3990195#3990195 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3990195

[JBoss jBPM] - Re: JBPM3 with tomcat

by meghanai_99

ok so finally I got the db created and deployed my jbpm web application on tomcat successfully. Now I get server error 500. Here is the stack trace - javax.faces.FacesException: Cannot get value for expression '#{userBean.userSelectItems}' org.apache.myfaces.context.servlet.ServletExternalContextImpl.dispatch(ServletExternalContextImpl.java:421) org.apache.myfaces.application.jsp.JspViewHandlerImpl.renderView(JspViewHandlerImpl.java:234) org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:300) javax.faces.webapp.FacesServlet.service(FacesServlet.java:95) org.apache.jasper.runtime.PageContextImpl.doForward(PageContextImpl.java:703) It is coming from login.jsp when it tries to resolve userSelectItems. How do I debug this now? Do I have specify these users somewhere so that they are created in db?

[JBossWS] - Consuming from EJB - how to specify port-component-ref using

by ajay662

I am on jboss 4.0.5, trying to implement ws client in one of my EJB, using jbossws-1.0.4.GA. I use xdoclet to generate my ejb-jar.xml. "Consuming Web Services" section of the JBossWS User Guide talks about adding a "service-ref" element to the EJB's deployment decriptor. But XDoclet doesn't seem to support "port-component-ref" element. And merge wouldn't do partial merge. With merge you have to provide complete deployment descriptor for that bean from an external file, which I am hesitant to do. Anybody else ran into this issue? Any suggestions for workaround?

[Remoting] - Re: Is Http Firewall tunneling in Remoting or Messaging ?

by fatbatman

Its possible to go through a series of steps when establishing a connection, to see what is possible. For example the client could firstly attempt a plain bidirectional TCP connection, if this fails, try the next approach etc, etc. Obviously if you know in advance that only a certain type of connection will be possible then that could be specified, perhaps as a parameter for the "connectToServer" method or simiar.
