Problem with JBPMSpringActionHandler

bcoulson — Tue, 12 Apr 2011 14:30:42 GMT

AllI am attempting to connect to my Java class from within an advanced worfklow step. I have defined my process definition as follows.<?xml version="1.0" encoding="UTF-8"?><process-definition xmlns="urn:jbpm.org:jpdl-3.1" name="scwfublishDocument"><swimlane name="initiator"/>

All

I have been looking into this problem further and have more details and really hope someone out there can help me solve this one. So I am pretty certain the issue is with the BeanFactory. The line of code that is causing the problem in JBPMSpringActionHandler is the line that calls factoryLocator.useBeanFactory(null) in the code fragment below.


    protected JBPMSpringActionHandler()
    {
        // The following implementation is derived from Spring Modules v0.4
        BeanFactoryLocator factoryLocator = new JbpmFactoryLocator();
        BeanFactoryReference factory = factoryLocator.useBeanFactory(null);
        initialiseHandler(factory.getFactory());
    }
‍‍‍‍‍‍‍‍‍

I then looked into the JbpmFactoryLocator class (a Spring class). I can only find version 0.5 online of the source so I am *assuming* that the difference between 0.4 and 0.5 for this file is negligible as I am looking at line 162 for the problem.


   public BeanFactoryReference useBeanFactory(String factoryKey) throws BeansException {
144      // see if there is a default FactoryBean
145      BeanFactory factory;
146
147      if (factoryKey == null) {
148         if (!canUseDefaultBeanFactory)
149            throw new IllegalArgumentException(
150                  "a non-null factoryKey needs to be specified as there are more then one factoryKeys available ");
151         factory = defaultFactory;
152      }
153      else {
154         factory = (BeanFactory) beanFactories.get(factoryKey);
155         if (factory == null)
156            throw new IllegalArgumentException("there is no beanFactory under key " + factoryKey);
157      }
158
159      // increment counter
160      synchronized (referenceCounter) {
161         Integer counter = (Integer) referenceCounter.get(factory);
162         referenceCounter.put(factory, new Integer(counter.intValue() + 1));
163      }
164
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Line 162 makes reference to the factory variable and I believe that may be null. Here is why. In the above code, it is possible for defaultFactory to be null IF canUseDefaultBeanFactory == true AND defaultFactory is null (which is the case if setBeanFactory is not called on the BeanFactory. Code for setBeanFactory below).


   public void setBeanFactory(final BeanFactory beanFactory) throws BeansException {
57 
58       // add the factory as default if possible (if it's the only one)
59       synchronized (JbpmFactoryLocator.class) {
60          if (canUseDefaultBeanFactory) {
61             if (defaultFactory == null) {
62                defaultFactory = beanFactory;
63                if (logger.isDebugEnabled())
64                   logger.debug("default beanFactoryReference=" + defaultFactory);
65             }
66             else {
67                if (logger.isDebugEnabled())
68                   logger.debug("more then one beanFactory - default not possible to determine");
69                canUseDefaultBeanFactory = false;
70                defaultFactory = null;
71             }
72          }
73       }
74 
75       // add name
76       addToMap(factoryName, beanFactory);
77       Integer counter = (Integer) referenceCounter.get(beanFactory);
78 
79       if (counter == null)
80          referenceCounter.put(beanFactory, new Integer(0));
81 
82       // add aliases
83       String[] aliases = beanFactory.getAliases(factoryName);
84       List names = new ArrayList(1 + aliases.length);
85       names.add(factoryName);
86       
87       for (int i = 0; i < aliases.length; i++) {
88          addToMap(aliases[i], beanFactory);
89          names.add(aliases[i]);
90       }
91 
92       // append previous found names
93       List previousNames = (List)beanFactoriesNames.get(beanFactory);
94       if (previousNames != null)
95          names.addAll(previousNames);
96       
97       beanFactoriesNames.put(beanFactory, names);
98       
99    }

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Furthermore I noticed the AlfrescoJbpmConfigurationFactoryBean class that implements BeanFactoryAware and FactoryBean<JbpmConfiguration> and i can see where it is included in the Spring context file (workflow-context.xml) as shown below.


   <bean id="jbpm_configuration" class="org.alfresco.repo.workflow.jbpm.AlfrescoJbpmConfigurationFactoryBean">
      <property name="sessionFactory" ref="sessionFactory"/>
      <property name="configuration" value="classpath:org/alfresco/repo/workflow/jbpm/jbpm.cfg.xml"/>
   </bean>
‍‍‍‍‍‍

Several questions.

1. What i cannot figure out is who calls setBeanFactory - is that done internally by Spring?
2. Do I need to register my Java class as a Spring bean? All other posts I have seen in this forum regarding a Java action for an advanced worfklow step do not mention the need to do this.But it seems as if there is an issue with my Spring configuration so I would like to know if this is a requirement that I am missing. If I do need to specify it, what, if anything, do I specify as parent attribute for bean?
3. Do I need to do anything else other than defining a Java class that extends JbpmSpringActionHandler and making a reference to it from my processdefinition file, and adding dependency jars to Alfresco?
4. Are there special jar files I need in addition to what is already in Alfresco?
5. Is the AlfrescoJavaScript class registered as a Spring bean? I thought if I could see its bean configuration, it may help me understand how to, if necessary, configure the Spring bean for a different ActionHandler.

Any help is greatly appreciate. I have been struggling with this for quite some time.

One more question - does it matter if I run this in Explorer or Share? I had assumed not, but wanted to point out that I am attempting to build this workflow in Share so that is where this behavior is exhibited. In fact, I can't even get my workflow to run in Explorer due to a TransientNode: taskId property not found error.

Re: Problem with JBPMSpringActionHandler

I have recently just created my own ActionHandler in Java and had very little problems…

I noticed in your processdefinition.xml file, your action tag had the following attribute:

config-type="bean"‍

I have not actually specified this as my action is not a bean. Take a look at some snippets from my configs:

processdefinition.xml:

      <task-node name="set-document-type">
         <task name="blfinwf:setDocumentTypeTask" swimlane="initiator">
            <description>Set Document Type</description>
            
            <event type="task-end">
               <action class="com.burris.common.bpm.actions.ForceChangeTypeAction" />
            </event>
            
            <controller>
               <variable name="blfinwf_documentType" />
            </controller>
         </task>
         
         <transition name="Submit" to="set-meta-data"></transition>
      </task-node>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

new-document-workflow-model.xml:

      <type name="blfinwf:setDocumentTypeTask">

bcoulson — Fri, 22 Apr 2011 21:15:03 GMT

Thanks - this does help to know that I am not going crazy. I did actually already remove the config-type attribute but it made no difference unfortunately. Question - did you have to add a bean to your spring configuration files? if so, could you please provide me that configuration detail? What version of Alfresco are you using BTW?

Thanks!
Brenda

Re: Problem with JBPMSpringActionHandler

I did not have to create a bean in the spring configuration files and we are running Alfresco Enterprise v3.4.0.

Re: Problem with JBPMSpringActionHandler

mcook — Mon, 25 Apr 2011 13:57:28 GMT

Based on the error, it looks like there is a problem in your someco-model-context.xml file. Could you post it in its entirety so I can take a look at it?

Re: Problem with JBPMSpringActionHandler

mcook — Mon, 25 Apr 2011 14:38:14 GMT

Ok so I dont think the problem is with your someco config file. Reading further down in the log file, I see this:

Caused by: org.springframework.beans.BeanInstantiationException: Could not instantiate bean class [gov.dhs.ipds.alfresco.AlfrescoHelper]: Constructor threw exception; nested exception is java.lang.NullPointerException‍

In the class I have defined, I did not specify a default constructor. I don't see why having this there is an issue, but I'd say comment it out or remove it and give that a try.

Re: Problem with JBPMSpringActionHandler

bcoulson — Mon, 25 Apr 2011 14:46:00 GMT

thanks for the quick reply. I should have said earlier - I noticed that myself and removed my default constructor. As you say, it is a difference between your solution and mine. However, my problem prevails - it made no difference to the behavior.

here is my new java code


package gov.dhs.ipds.alfresco;

import org.alfresco.repo.workflow.jbpm.JBPMSpringActionHandler;
import org.springframework.beans.factory.BeanFactory;
import org.jbpm.graph.exe.ExecutionContext;

public class AlfrescoHelper extends  JBPMSpringActionHandler {

   private static final long serialVersionUID = 1000L;

   public void execute(ExecutionContext ctx) throws Exception {
      System.out.println("Inside AlfrescoHelp.execute()");
   }
   
   @Override
   protected void initialiseHandler(BeanFactory factory) {
      System.out.println("Inside AlfrescoHelper.initialiseHandler()");
      // TODO Auto-generated method stub
   }
}
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I am quite certain that I have a null BeanFactory based on the line of code where it is breaking but the question is why is my beanFactory null?

Re: Problem with JBPMSpringActionHandler

mcook — Mon, 25 Apr 2011 17:40:17 GMT

Ok looking closer at your context file… I am noticing some differences… in particular the workflow section…

   <bean id="extension.workflowBootstrap" parent="workflowDeployer">
      <property name="labels">
         <list>
            <value>alfresco/extension/scWorkflow</value>
         </list>
      </property>
   </bean‍‍‍‍‍‍‍

All you have listed are the workflow labels. You also need to specify the workflow definitions. For example:

   <bean id="burris.workflowBootstrap" parent="workflowDeployer">
      <property name="workflowDefinitions">
         <list>
            <props>
               <prop key="engineId">jbpm</prop>
               <prop key="location">alfresco/extension/burris/finance/workflows/newFinanceDocument/processdefinition.xml</prop>
               <prop key="mimetype">text/xml</prop>
               <prop key="redeploy">true</prop>
            </props>
         </list>
      </property>
      
      <property name="labels">
         <list>
            <!– Finance Workflow Labels –>
            <value>alfresco.extension.burris.finance.workflows.new-finance-document-workflow-messages</value>
         </list>
      </property>
   </bean>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hope this helps…

bcoulson — Mon, 25 Apr 2011 17:57:53 GMT

Thanks for your help. I will add those to my context file, although I don't believe that is the issue as I deploy my workflow from Eclipse using the hot deploy option of jBPM, but it is worth a try to add the configuration into the spring bean.

I will try this and let you know.

Re: Problem with JBPMSpringActionHandler

mcook — Tue, 26 Apr 2011 12:42:10 GMT

To me it would make sense (that is if this is the problem). You are getting a null pointer exception from a bean factory, which is trying to instantiate the workflow bootstrap bean. Because the workflow definitions property is not there, it is essentially passing in null for something that is required. Im not sure how the eclipse deployer works as I have never used it, so I can't help you there. I have always just manually deployed a new/modified workflow. I would think in either case (manual vs eclipse) you would still have to define the workflow definition property because that is how spring/alfresco recognizes its there… if I were to take a guess, the eclipse deployer is just copying the files over for it to be deployed, ie the processdefinition.xml, example-workflow-model.xml, etc.

Re: Problem with JBPMSpringActionHandler

bcoulson — Tue, 26 Apr 2011 20:37:40 GMT

Thank you for continuing to assist me! I added the workflow definition to my spring bean context file but to no avail - I still get the same error. I am now wondering if I should go back to a previous version of Alfresco. You are using 3.4a is that correct? I am on 3.4d and I also tried it on 3.4c with the same results. But I have not tried 3.4a.

Here is my new context file.

Re: Problem with JBPMSpringActionHandler

mcook — Tue, 26 Apr 2011 21:15:14 GMT

I am not running alfresco 3.4a. The enterprise version only has 3.4.0 and 3.4.1 and these are not options for selection on this forum, so I just picked one that was close to the version we have.

As per the error, Ill keep looking into it and see what else I can dig up.

Re: Problem with JBPMSpringActionHandler

mcook — Tue, 26 Apr 2011 21:32:04 GMT

Can you tell me what is on line 15 of AlfrescoHelper?

Re: Problem with JBPMSpringActionHandler

mcook — Wed, 27 Apr 2011 14:18:40 GMT

Could you post the error you get (even if its the same as before) with your constructor removed?

Re: Problem with JBPMSpringActionHandler

bcoulson — Wed, 27 Apr 2011 14:35:12 GMT

Thank you very much for your persistence in trying to help me.

Here is the latest AlfrescoHelper code with line numbers. Line 15 is the @Override annotation so I am not sure where you got a reference to line 15? Perhaps that was in the old file that had the constructor in it, I am assuming? In which case I believe it would be the initialiseHandler method.
