[JBoss JIRA] Created: (JBPM-2789) Java task field injection works when java class is on the Spring context

by Robert Moskal (JIRA)

Java task field injection works when java class is on the Spring context ------------------------------------------------------------------------ Key: JBPM-2789 URL: https://jira.jboss.org/jira/browse/JBPM-2789 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.1 Environment: Nothing unusual, hsql, jetty. Reporter: Robert Moskal If I create a java task that pulls from the spring context, like so: <java expr="#{pipelineNode}" g="300,79,92,52" method="execute" name="Rig"> <field name="execution"><object expr="#{execution}"/></field> <field name="allowableFlows"><string value="NormalFlow2"/></field> <transition g="-31,-28" name="success" to="Animate"/> <transition g="303,252:-25,-32" name="to Rework" to="Rework"/> </java> Then none of the field injectors work. However if I change the definition to one where I instantiate using the class: <java class="com.bluesky.skyline.workflow.extensions.PipelineNode" g="123,78,127,52" method="execute" name="Model">  <field name="allowableFlows"><string value="NormalFlow2"/></field> <transition g="-31,-28" name="success" to="Rig"/> <transition g="-24,-58" name="to Rework" to="Rework"/> </java> Then they work as expected. Whats' interesting is that in the latter case the Execution isn't injected.However, if I add the execution in an argument to my method: <arg><object expr="#{execution}"/></arg> Then it is passed in correctly. I suspect this has to do with the way the java code is stored with the process. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2762) XML Schema Validation errors in jpdl files don't get reported when deploying them

by Erwin Bolwidt (JIRA)

XML Schema Validation errors in jpdl files don't get reported when deploying them --------------------------------------------------------------------------------- Key: JBPM-2762 URL: https://jira.jboss.org/jira/browse/JBPM-2762 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.2, jBPM 4.3 Reporter: Erwin Bolwidt When I deploy an invalid JPDL file (take a valid file, add <abc/> at some random location, voila) through the RepositoryService, the deployment succeeds. I can see that the validation error is reported internally, but an exception is not thrown. It is also not possible for the caller to determine that there was a validation error, unless the caller is willing to cast NewDeployment to DeploymentImpl and invoke the methods from the ProblemList superclass. The thing is, DeployerManager (line 49, jbpm 4.3) checks that there haven't been any errors using ProblemList#hasErrors(). And ProblemList#hasErrors() returns true if there is at least one problem with severity ProblemImpl.TYPE_ERROR. However, validation errors are reported with severity ProblemImpl.TYPE_XML_VALIDATION_ERROR. Of course I don't know the reasons why the developer of this code choose this implementation, but to me it seems that this was an oversight and the hasErrors() should have checked for TYPE_XML_VALIDATION_ERROR as well. I haven't had a chance yet to see how a process definition with an invalid jpdl file functions in practice, but it doesn't seem right that you can deploy an incorrect process definition. And if it was right, for some reason, then I think the caller should have a chance to find out, so in that case the interface NewDeployment could be extended with methods to retrieve any problems during deployment. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2768) Provide API for accessing JBPM email infrastructure

by Peter Horvath (JIRA)

Provide API for accessing JBPM email infrastructure --------------------------------------------------- Key: JBPM-2768 URL: https://jira.jboss.org/jira/browse/JBPM-2768 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Affects Versions: jBPM 4.x Reporter: Peter Horvath Currently there is no way to access JBPM email infrastructure from custom Java code (for example from an EventListener, or ActivityBehaviour) It would be good to be able to access JBPM email subsystem through a public API. Adding a new Facade class with a single method that allows you to select the email template and pass an org.jbpm.api.Execution should be quite easy to implement and would add a lot of power to EventListeners, etc. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2763) jBPM 4.3 - InitialContext is not closed after being used for JNDI Lookup (Multiple classes)

by Martin Porter (JIRA)

jBPM 4.3 - InitialContext is not closed after being used for JNDI Lookup (Multiple classes) ------------------------------------------------------------------------------------------- Key: JBPM-2763 URL: https://jira.jboss.org/jira/browse/JBPM-2763 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.3 Reporter: Martin Porter In various classes when an InitialContext is created it is not closed before the method returns. The following classes have this issue:- org.jboss.bpm.console.server.util.InvocationProxy org.jbpm.jpdl.internal.activity.JavaActivity org.jbpm.jpdl.internal.activity.JmsActivity org.jbpm.pvm.internal.cfg.ConfigurationImpl org.jbpm.pvm.internal.processengine.ProcessEngineImpl org.jbpm.pvm.internal.tx.JtaTransaction org.jbpm.pvm.internal.wire.descriptor.JbossIdmIdentitySessionFactoryDescriptor org.jbpm.pvm.internal.wire.descriptor.JndiDescriptor Hence this will result in memory leaks and also issues with hot deployment for EAR's containing the process engine. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2698) AssignmentHandler allows assignment of task to non-existing groups

by Martin Porter (JIRA)

AssignmentHandler allows assignment of task to non-existing groups ------------------------------------------------------------------ Key: JBPM-2698 URL: https://jira.jboss.org/jira/browse/JBPM-2698 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.2 Environment: Windows Vista, Oracle 11g, jBPM 4.2, Eclipse 3.5 Reporter: Martin Porter Priority: Minor An assignment handler (implementing AssignmentHandler) can invoke assignable.addCandidateGroup(XXX) for groups that do not actually exist in the DB. The group should be validated or else the task will be assigned to a non-existing group and never picked up. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2682) Add problem specific exception sub-classes

by Peter Horvath (JIRA)

Add problem specific exception sub-classes ------------------------------------------ Key: JBPM-2682 URL: https://jira.jboss.org/jira/browse/JBPM-2682 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.x Reporter: Peter Horvath Currently error conditions are signaled using a single exception type, JbpmException. Using problem specific exception subclasses would make it possible for the client code to deal with different error conditions differently . Example - current GetOutcomes command implementation: package org.jbpm.pvm.internal.cmd; ... public class GetOutcomes implements Command<Set<String>> { ... public Set<String> execute(Environment environment) { DbSession dbSession = environment.get(DbSession.class); TaskImpl task = dbSession.get(TaskImpl.class, Long.parseLong(taskId)); if (task==null) { throw new JbpmException("task "+taskId+" doesn't exist"); } ... Introducing problem specific exception subclasses would allow client code to handle errors much better; for example if a custom TaskDoesNotExistException (public class TaskDoesNotExistException extends JbpmException) was thrown in GetOutcomes.execute when a task is not found, then the caller code would be able to distinguish this problem from say a transient database connectivity problem. It could display a user friendly error message rather than showing a generic error message etc: public Set<String> execute(Environment environment) { DbSession dbSession = environment.get(DbSession.class); TaskImpl task = dbSession.get(TaskImpl.class, Long.parseLong(taskId)); if (task==null) { throw new TaskDoesNotExistException("task "+taskId+" doesn't exist"); } The same approach for process instances, executions, variables, etc. could be used to allow building robust client code. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2625) Add count() to Queries to support pagination

by Peter Horvath (JIRA)

Add count() to Queries to support pagination -------------------------------------------- Key: JBPM-2625 URL: https://jira.jboss.org/jira/browse/JBPM-2625 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Components: Runtime Engine Affects Versions: jBPM 4.x Reporter: Peter Horvath Queries provide a powerful interface to access JBPM tasks, jobs, deployments, etc; currently the only way you can get the number of results that match a filter is to load the whole list, and determine its size by calling .size() method - this is extremely inefficient and can even cause OutOfMemoryError (e.g. a HistoryActivityInstanceQuery could return tens of thousands elements) count() could be used with page(int firstResult, int maxResults) method to create a paginated result list where you can display the number of pages -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2636) NPE in Configuration.getProcessEngine() when using jbpm.jbossremote.cfg.xml

by Mark Roy (JIRA)

NPE in Configuration.getProcessEngine() when using jbpm.jbossremote.cfg.xml --------------------------------------------------------------------------- Key: JBPM-2636 URL: https://jira.jboss.org/jira/browse/JBPM-2636 Project: jBPM Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: jBPM 4.2 Environment: Windows XP, JDK 6, JBoss, Oracle 10g Reporter: Mark Roy In jBPM 4.1, using the following jbpm.cfg.xml in my simple test app worked: Code: <jbpm-configuration> <import resource="jbpm.jbossremote.cfg.xml" /> </jbpm-configuration> Since upgrading to 4.2, however, I now get a NPE: Code: java.lang.NullPointerException at org.jbpm.pvm.internal.cfg.ProcessEngineImpl.checkDb(ProcessEngineImpl.java:177) at org.jbpm.pvm.internal.cfg.ProcessEngineImpl.buildProcessEngine(ProcessEngineImpl.java:170) at org.jbpm.api.Configuration.getProcessEngine(Configuration.java:161) at org.jbpm.test.JbpmTestCase.initialize(JbpmTestCase.java:81) at org.jbpm.test.JbpmTestCase.setUp(JbpmTestCase.java:76) at com.mydomain..ReviewProcess.setUp(ReviewProcess.java:24) at junit.framework.TestCase.runBare(TestCase.java:132) at junit.framework.TestResult$1.protect(TestResult.java:110) at junit.framework.TestResult.runProtected(TestResult.java:128) at junit.framework.TestResult.run(TestResult.java:113) at junit.framework.TestCase.run(TestCase.java:124) at junit.framework.TestSuite.runTest(TestSuite.java:232) at junit.framework.TestSuite.run(TestSuite.java:227) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:13 0) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) I traced this to the fact the userCommandService is assigned null from the following: Code: userCommandService = (CommandService) processEngineWireContext.get(CommandService.NAME_TX_REQUIR ED_COMMAND_SERVICE); This problem can be easily reproduced using the examples included in the distribution. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (JBPM-2842) Use Singletons as "custom" or "java" activity (state) processors

by track lead (JIRA)

Use Singletons as "custom" or "java" activity (state) processors ---------------------------------------------------------------- Key: JBPM-2842 URL: https://jira.jboss.org/jira/browse/JBPM-2842 Project: jBPM Issue Type: Feature Request Security Level: Public (Everyone can see) Reporter: track lead Presently, jBPM execution engine creates a new instance of the Java class associated with a state / activity. We would like to use pre-configured instances as custom and Java activity handlers and/or for decision making. It would also be wonderful to be able to use Spring beans as activity handlers. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
