It works, that it isn't an inmem db. But everytime the engine is startet again, all content of db is overwritten. I think the problem is an "create"-statement somewhere, where an "update" should be inserted. But I just dont know where... Here's sample code: public static void main(String[] args) {         try {             RuntimeManager manager = getRuntimeManager("processDefinition/simpleTestProcess.bpmn");                    RuntimeEngine runtime = manager.getRuntimeEngine(EmptyContext.get());             KieSession ksession = runtime.getKieSession();                           ksession.startProcess("serviceTestProcess");         } catch (Throwable t) {             t.printStackTrace();         }     }   private static RuntimeManager getRuntimeManager(String process) {         JBPMHelper.startH2Server();         Properties properties = new Properties();         PoolingDataSource pds = new PoolingDataSource();         pds.setUniqueName(properties.getProperty("persistence.datasource.name", "jdbc/jbpm-ds"));         pds.setClassName("bitronix.tm.resource.jdbc.lrc.LrcXADataSource");         pds.setMaxPoolSize(5);         pds.setAllowLocalTransactions(true);         pds.getDriverProperties().put("user", properties.getProperty("persistence.datasource.user", "sa"));         pds.getDriverProperties().put("password", properties.getProperty("persistence.datasource.password", "sa"));         pds.getDriverProperties().put("url", properties.getProperty("persistence.datasource.url", "jdbc:h2:~/JBPM/process_jbpm;MVCC=TRUE"));         pds.getDriverProperties().put("driverClassName", properties.getProperty("persistence.datasource.driverClassName", "org.h2.Driver"));         pds.init();           RuntimeEnvironment environment = RuntimeEnvironmentBuilder.getDefault()             .addAsset(ResourceFactory.newClassPathResource(process), ResourceType.BPMN2)             .get();         return RuntimeManagerFactory.Factory.get().newSingletonRuntimeManager(environment);     } Please let me know, where/how to fix the problem.
