[JBoss Seam] - Re: [2.0 beta1 CVS]SeamTest RARDeployment question

by enzhao

Now I see the jms-ds.xml in the bootstrap/deploy/messaging folder and the hsqlds-ds.xml in the bootstrap/deploy folder. And I also see jboss-beans.xml was removed from the configuration. Was the removal of jboss-beans.xml intentional or? Gavin could you please tell me about these lines in the hsqlds-ds.xml: |  | <connection-url>jdbc:hsqldb:${jboss.server.data.dir}${/}hypersonic${/}localDB</connection-url> | 1. Do I need to manually add the org.jboss.jdbc.HypersonicDatabase mbean? If so, in which file? Jboss-beans.xml or somewhere else? 2. How is the variable ${jboss.server.data.dir}$ passed to this file? I could not find the definition of the jboss.server.data.dir in the configuration files in the bootstrap folder. If I missed it, could you please tell me in which file is this variable defined? 3. Interestingly, although the SeamTest always failed on init(), but the bootstrap/data folder is already filled with data. (At the beginning it was just an empty folder) Any story about that? Thank you very much in advance!!

[JBoss Seam] - params in pageflows?

by Delphi's Ghost

What I'm trying to do is at the end of a pageflow, go back to the original page that started the page flow, in this case the widgetView page. To do so I need to pass the widgetId as a request parameter so the widgetView knows which widget to display. I see from the xml schema that pageflows don't support params anywhere, and since I ended the pageflow, the conversation has completed, so there is no way to access that information. Using pages.xml navigation, I can pass param values on the redirects. Should I just use pages.xml for my pageflow exit actions and end the conversation from there? Anyone have any other suggestions on how to pass information out of the pageflow? Should I create a Jira to suggest the idea of params in pageflows?

[JBoss Seam] - Re: Migrate my current application to Seam?

by gavin.king＠jboss.com

Of your possible choices I definitely don't recommend using stateless session beans everywhere. You should use an appropriate mix of stateless and stateful if you take the EJB route. If you don't take the EJB route, you have a choice between Seam POJOs or Spring POJOs. In a JSF-based architecture, there is a compelling reason to choose Seam components: the contextual state management model is simply a much better fit to JSF, and the next rev of Java EE will include this model (the Web Beans spec). So it comes down to session beans or not session beans. Your choice. Try out EJB3. If you like it, stick with it. If you don't, use plain Seam components. You can always change your mind later. Note that there are a couple of problems for which you really do need EJB in Seam: eg. REQUIRES_NEW transactions and message-driven beans. However, you can always mix and match.

[JBoss Seam] - Re: [2.0 beta1 CVS]SeamTest RARDeployment question

by enzhao

Yes, bootstrap is in my classpath and build.xml. I've updated the project configuration with the help of seam-gen came with the latest CVS. But still having this problem. Now I'm trying to figure out all the configuration files in the bootstrap folder...Will post again when I find a more specific trial.... Thanks!

[JBoss Seam] - Re: Which entities should be registered as Seam components?

by pete.muir＠jboss.org

I would not register any entities as Seam components, but instead manage them using a Seam component, as discussed here http://docs.jboss.com/seam/1.3.0.ALPHA/reference/en/html/framework.html#d... - the reference manual discusses the advantages of this approach. And yes, you don't need to manage all your entities, just those which you want to refer to in EL.

[JBoss Seam] - Re: How best to leverage Seam when you've got a HUGE domain?

by gavin.king＠jboss.com

I don't fully understand what the difference between the two approaches is. By "DAO or service" you mean something in a different process?

[JBoss Seam] - Re: jBPM and Seam Events question

by gavin.king＠jboss.com

This is the exception you get from Hibernate when two concurrent transactions try to update the same data (in this case the jBPM token for the process instance). It is probably because your async process runs at the same time as the process that initiated it. Try putting a delay on the async process.

[JBoss Messaging] - Re: Selector Help needed - Possible alternative suggestions

by anhminh_tran

BTW here is the consumer that I made. It's a modification of the one that came with the example code: | public class JMSConsumer { | | public static void main(String[] args) { | String jndiDestinationName = "/queue/testQueue"; | InitialContext ic = null; | Connection connection = null; | boolean deployed = false; | | try { | if (!Util.doesDestinationExist(jndiDestinationName)) { | System.out.println("Destination " + jndiDestinationName + " does not exist, deploying it"); | Util.deployQueue(jndiDestinationName); | deployed = true; | } | | ic = new InitialContext(); | ic.addToEnvironment("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory"); | ic.addToEnvironment("java.naming.provider.url", "jnp://10.5.1.241:1099"); | ic.addToEnvironment("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces"); | | ConnectionFactory cf = (ConnectionFactory) ic.lookup("/ConnectionFactory"); | Queue queue = (Queue) ic.lookup(jndiDestinationName); | | connection = cf.createConnection(); | Session session = connection.createSession(false, Session.CLIENT_ACKNOWLEDGE); | | MessageConsumer consumer = session.createConsumer(queue); | | connection.start(); | | System.out.println("Waiting for messages"); | System.out.println("--------------------"); | while (true) { | TextMessage message = (TextMessage) consumer.receive(2000); | if (message != null) { | System.out.println("message=" + message.getText()); | System.out.println("-------------------------------"); | | // Acknowledge that we've recieved and processed the message successfully | message.acknowledge(); | Thread.sleep(15000); | } | } | } | catch (Exception e) { | e.printStackTrace(); | } | finally { | try { | if (deployed) { | Util.undeployQueue(jndiDestinationName); | } | } | catch (Exception e) { | e.printStackTrace(); | } | | if (ic != null) { | try { | ic.close(); | } | catch (Exception e) { | e.printStackTrace(); | } | } | | // ALWAYS close your connection in a finally block to avoid leaks | // Closing connection also takes care of closing its related objects | // e.g. sessions | try { | if (connection != null) { | connection.close(); | } | | } | catch (JMSException jmse) { | System.err.println("Could not close connection " + connection + " exception was " + jmse); | jmse.printStackTrace(); | } | } | } | | } | It seems that on the call to consumer.receive() it gets a batch of messages no matter if I set the PrefetchSize attribute to 1 or not..

[JBoss Seam] - Re: [1.3 cvs] Trinidad svg generation error

by wesleyhales

When in doubt, read the documentation... | templateSource="chart.svg" | Just add that as an attribute and point it to a working svg It still doesn't excuse why Tomcat would be adding extra characters in the response buffer *speculation*, but it gets me past the error.
