[rules-dev] Issue with jBPMHelper

Hi, I have created a java + spring project to run a HumanTask example on Apache Karaf. To instantiate the class, I use spring like this <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd "> <bean id="humanTaskExample" class="org.jbpm.osgi.example.HumanTaskExample" init-method="configure"/> </beans> public class HumanTaskExample { public static void configure() { RuntimeManager manager = getRuntimeManager("humantask/HumanTask.bpmn"); ... private static RuntimeManager getRuntimeManager(String process) { // load up the knowledge base JBPMHelper.startUp(); ... The JBPMHelper class used corresponds to : https://github.com/droolsjbpm/jbpm/blob/master/jbpm-test/src/main/java/or... But when spring creates the dataSource, I get this error : Caused by: bitronix.tm.resource.ResourceConfigurationException: cannot create JDBC datasource named jdbc/jbpm-ds at bitronix.tm.resource.jdbc.PoolingDataSource.init(PoolingDataSource.java:80) at org.jbpm.osgi.example.JBPMHelper.setupDataSource(JBPMHelper.java:79) at org.jbpm.osgi.example.JBPMHelper.startUp(JBPMHelper.java:49) at org.jbpm.osgi.example.HumanTaskExample.getRuntimeManager(HumanTaskExample.java:88) at org.jbpm.osgi.example.HumanTaskExample.configure(HumanTaskExample.java:28) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)[:1.6.0_45] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39)[:1.6.0_45] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25)[:1.6.0_45] at java.lang.reflect.Method.invoke(Method.java:597)[:1.6.0_45] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeCustomInitMethod(AbstractAutowireCapableBeanFactory.java:1546)[91:org.springframework.beans:3.0.7.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.invokeInitMethods(AbstractAutowireCapableBeanFactory.java:1487)[91:org.springframework.beans:3.0.7.RELEASE] at org.springframework.beans.factory.support.AbstractAutowireCapableBeanFactory.initializeBean(AbstractAutowireCapableBeanFactory.java:1419)[91:org.springframework.beans:3.0.7.RELEASE] ... 14 more Caused by: java.lang.IllegalArgumentException: resource with uniqueName 'jdbc/jbpm-ds' has already been registered at bitronix.tm.resource.ResourceRegistrar.register(ResourceRegistrar.java:74) at bitronix.tm.resource.jdbc.PoolingDataSource.buildXAPool(PoolingDataSource.java:92) at bitronix.tm.resource.jdbc.PoolingDataSource.init(PoolingDataSource.java:76) Any idea is welcome Regards, -- Charles Moulliard Apache Committer / Sr. Enterprise Architect (RedHat) Twitter : @cmoulliard | Blog : http://cmoulliard.blogspot.com
