jBPM process after workflow node using ActionHandler

jBPM process after workflow node using ActionHandler

Simple article to show how to do processing after each workflow node and also send values from workflow to ActionHandler 

<node name="Process Node">
  <action class="org.jboss.soa.esb.services.jbpm.actionhandlers.EsbActionHandler">
   <esbCategoryName>
    ESB_PROCESSOR_QUOTE
   </esbCategoryName>
  </action>
  <event type="node-leave">
                    <action class="event.CustomNodeComplete">
                              <actionName>Quote Successful</actionName>
                     </action>
         </event>
  <transition to="Complete"></transition>
 </node>

Workflow ProcessDefinition

actionName is passed to the ActionHandler and  execute method will be called if workflow node completes  successfully 

ActionHandler

public class  CustomNodeComplete implements ActionHandler {


 private static final long serialVersionUID = -6446921306976005512L;
 String actionName;
 
 
 @Override
 public void execute(ExecutionContext execContext) throws Exception {

     //actionName  from workflow available

     // send notification
 }

jBPM Node for Decision using ActionHandler

jBPM use non-decision node to choose workflow path

You can use the decision node to choose one of the workflow path . This is to show a workaround if you have constrains using the decision node.  Shown below simple workflow and can either branch to  "Yes" path or "No" path based on the decision by Node - ValidQuote

Action Handler ( defined in the ValidQuote)

package event;
import org.jbpm.graph.exe.ExecutionContext;

public class  ValidQuote implements ActionHandler {

 @Override
 public void execute(ExecutionContext execContext) throws Exception {

 if( somecondition...)
  execContext.leaveNode("Yes");
 else
  execContext.leaveNode("No");
 }

SOAP UI Dynamic mock service using Groovy Script

SOAP UI Dynamic mock service using Groovy Script

Create dynamic mock service using SOAP UI . You will just need the WSDL . You should be familiar using the soap ui and creating the mock service . Following is to only make it dynamic

1. Create a SoapUI project using the WSDL . Right click and select the mock service .
2. Select the  WebService Method and Open the Response that has to be customized
3. Create two files for Success and Error response and place them in folder  {Project-Path}/responses
4. WebService Response ( Right portion of the Soap UI Window )will be made dynamic based on request.  Delete everything from mock response and  replace with${content} .  This value will be dynamically rendered from  groovy script
   
5. Choose Dispatch -> Script , and then choose Dynamic Reponse
   
6. Use the groovy script below , to render Success and Error Responses .

It works in the following way ,

• if quotenumber is 9999  - send Error response
• anything else - send Success Response

Now you can create more test cases and test them by changing the input in the xml . Providing  the input , output and the script below


Input ( for ref )

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:test="http://www.testing.com/WS/quoteWS">

  <soapenv:Header/>

  <soapenv:Body>

     <test:Quote>

        <QuoteRequest>

           <quoteNumber>9999</quoteNumber>

           <quoteTitle>?</quoteTitle>

           <quotePrice>?</quotePrice>

        </QuoteRequest>

     </test:Quote>

  </soapenv:Body>

</soapenv:Envelope>'

Output

Success

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:test="http://www.testing.com/WS/quoteWS">

  <soapenv:Header/>

  <soapenv:Body>

     <test:QuoteResponse>

        <QuoteReply>

           <status>Success</status>

           <!--Optional:-->

           <errorCode>0</errorCode>

           <!--Optional:-->

           <errorMessage></errorMessage>
