Hi! I'm trying to create a schedule service at jboss 4.2.1 but I'm not sure what to do. I need a service to be started by the application server that runs every half an hour. I wrote a class but the problem is when I start jboss, I have the following error message: anonymous wrote : 10:11:11,280 ERROR [TimerServiceImpl] Cannot create txtimer | java.lang.IllegalStateException: Unable to persist timer anonymous wrote : Caused by: java.sql.SQLException: Unique constraint violation: in statement [insert into TIMERS (TIMERID,TARGETID,INITIALDATE,TIMERINTERVAL,INSTANCEPK,INFO) values (?,?,?,?,?,?)] Here is the class: | @Service | @Management(AtividadeTimerServiceManagement.class) | public class AtividadeTimerServiceBean implements AtividadeTimerServiceLocal, | AtividadeTimerServiceManagement { | | @Resource | private TimerService timerService; | | public void create() throws Exception { | this.timerService.createTimer(15*60*1000, 5*60*1000, null); | } | | public void destroy() { | | } | | public void start() throws Exception { | } | | public void stop() { | } | | @Timeout | public void monitorPeriodoCadastral(Timer timer) { | log.info("monitorPeriodoCadastral..."); | } | } | Does anybody have any idea why am I getting this error message? Thanks!

[JBoss Seam] - DocumentStore usage change - Urgent!!!

by zerok

Hi folks, We are using Seam 2.0.1.CR1. We have to generate PDFs and put it into DocumentStore for latter use. I've found this bunch of code: String id = DocumentStore.instance().newId(); DocumentData data = new DocumentData("manual.pdf",DocumentData.DocType.PDF, manualBytes); DocumentStore.instance().saveData(id, data); return DocumentStore.instance().preferredUrlForContent("manual.pdf", DocumentData.DocType.PDF, id); The problem is that DocumentData doen not have DocType inner class anymore and the actual inner class doesn't have a replacement constant for PDF's Doctype. So the code doesn't work anymore! Does anyone can provide an alternative to the code above for 2.0.1.CR1? any help you can give will be much appreciated!

[Tomcat, HTTPD, Servlets & JSP] - How do HttpSession work?

by flowerfan

Hello, could you please explain me how HttpSessions work? When and by whom are they created? (How) Can HttpSessions be shared between different Servlets? If a servlet method receives a SessionId through a parameter, how can the session id be validated? (Is there a way to query all active sessions from within a servlets method?) Please enlighten me. Thanks in advance!

[Microcontainer] - Question on Capabilities definition (ClassLoaderMetaData)

by gcompienne

Hello, Looking at the JBoss MC source code I can see that a "describe" deployer can add capabilities information before the classloader gets created("ClassLoaderMetaData.setCapabilities()"), thus allowing dependency resolution for a unit being deployed. Now, I wonder about the deployer themselves: How could a deployer (that is being deployed) inform MC of its own capabilities? Is there a mechanism to do that? The only option I can see, so far, is to create another deployer (in a different deployment unit) that would declare the capabilities my deployer. But I can't shake the feeling that I am probably trying to kill a fly with a hammer... ;-) Thanks for your help. Gilles.

[JBoss jBPM] - Re: Problem with nodes with async=

by osganian

Does anybody know if ansyc nodes are supported in 3.2.2? The user guide mentions classes that don't exist in the 3.2.2 distribution like CommandExecutor, ExecuteNodeCommand and ExecuteActionCommand. Also the AsynchronousCommand's execute method throws a UnsupportedOperationException. Also the 3.2.2 user guide mentions the JBPM_MESSAGE table but this table isn't part of that distribution but a previous 3.1 distribution. Can anybody shed any light on this for me? Thanks.

[JBoss Seam] - Re: Schedule Reports to Run Daily at Certain Time

by JavaDeveloperX

You can configure your Jboss to not persist the timer: in \server\default\deploy\ejb-deployer.xml change persistencePolicy to 'noop': | <mbean code="org.jboss.ejb.txtimer.EJBTimerServiceImpl" | name="jboss.ejb:service=EJBTimerService"> | <attribute name="RetryPolicy">jboss.ejb:service=EJBTimerService,retryPolicy=fixedDelay</attribute> | <attribute name="PersistencePolicy">jboss.ejb:service=EJBTimerService,persistencePolicy=noop</attribute> | <attribute name="TimerIdGeneratorClassName">org.jboss.ejb.txtimer.BigIntegerTimerIdGenerator</attribute> | <attribute name="TimedObjectInvokerClassName">org.jboss.ejb.txtimer.TimedObjectInvokerImpl</attribute> | <depends optional-attribute-name="TransactionManagerFactory" proxy-type="org.jboss.tm.TransactionManagerFactory"> | jboss:service=TransactionManager | </depends> | </mbean> | View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4127796#4127796 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4127796

[JBoss Seam] - Re: Schedule Reports to Run Daily at Certain Time

by baspet

Hi, i had the same issue. I solved it calling "select count(*) from qrtz_job_details" and if count > 0 just skip. It's not exactly what i wanted but it works. Any better idea from seam team would be welcomed. V.

[JBoss Seam] - Exception handling with interceptors

by nickarls

Hi, I have most reuseable database queries isolated to a DAOish class and would like to add some logging and exception handling like | Object result = null; | try { | result = context.proceed(); | // log called methods, parameters and result | } catch (PersistenceException e) { | // get error context from invocation context and lookup | // from message bundles etc... | } | return result; | The problem however is that the connection seems to have gone sour anyway, which leads to ugly "Transaction is not active" errors in my long running conversation. Is there any way to recover from this? Do you have any experience with using interceptors for centralized error logging/management and recovery?

[EJB 3.0] - Re: Deploy Problem

by jaikiran

Which Java version do you use on the server side. On the client side, i see that you are using Java 1.6. Might sound weird, but can you try using 1.5 and see if it's working?
