I am using jBPM for more than a year now and had my ups and downs with it. However the “Business Process Management with JBoss jBPM” by Matt Cumberlidge from packt was an interesting read. What the book does is to present the problems from a business analyst point of view and as doing such it presents a lot about the actual activities which take place in order to implement a BMP while following an implementation scenario stage by stage....
In new versions of JBoss (such the 4.0.5 which I am using) there is a quartz-ra.sar service which should allow me to define some a job with a cron like specification. Searching the forums and the jboss site I was able to put together quickly an example: import org.jboss.annotation.ejb.ResourceAdapter;import org.jboss.logging.Logger;import org.quartz.Job;import org.quartz.JobExecutionContext;import org.quartz.JobExecutionException; import javax.ejb.MessageDriven;import javax.ejb.ActivationConfigProperty; @MessageDriven(activationConfig = { @ActivationConfigProperty(propertyName = "cronTrigger", propertyValue = "0/2 * * * * ?") }) @ResourceAdapter("quartz-ra....
Getting the correct date and time was always a problem but I could not expect it’s still a problem on today java and OS versions. Trying to deploy a JBoss on various Linux and JBoss I could not notice that on each system the date in the log was different from the localtime. Initially I thought it’s just a JBoss configuration problem but a simple example shows it’s not: import java....
Applies to: JBPM 3.1.2, JBoss 4.0.5-GA Everything starts with a beautiful concept but has to pass past those nasty errors. The same applies to this JBPM project, everything was nice, I have seen it running and then I was supposed to take the sources, clean, organize and enhance. Everything ok until now. The only problem is that when deploying the JBPM (sar) service there was this error: 16:09:17,402 ERROR [CommandExecutorThread] org....
Applies to: JBoss 4.0.5 GA Everything started with a web application which worked perfectly inside a Tomcat 5 container and had to be migrated to JBoss. At the first deployment got this error: 14:45:56,496 ERROR [STDERR] log4j:ERROR The class "org.apache.log4j.spi.ErrorHandler" was loaded by 14:45:56,496 ERROR [STDERR] log4j:ERROR [WebappClassLoader delegate: false repositories: /WEB-INF/classes/----------> Parent Classloader:java.net.FactoryURLClassLoader@172bab9] whereas object of type 14:45:56,497 ERROR [STDERR] log4j:ERROR "org.jboss.logging.util.OnlyOnceErrorHandler" was loaded by [org.jboss.system.server.NoAnnotationURLClassLoader@19616c7].14:45:56,542 ERROR [STDERR] log4j:ERROR Could not create an Appender....
Applies to: JBoss 4.0.5 GA As I am working on a rather complex application with a lot of dependancy bounded MBeans I found it necessary to have a small application, in a different JVM, invoke a MBean method for administrative purposes. Even if this sounded easy at the begining it seemed that I had to face 2 problems: JBoss JMX implementation JAAS access to the secured console Since I both googled and searched JBoss forums without much help I decided, upon succeding, to write this article as it might help someone futher....
