jBPM customization and custom workflow deployment

[dbz]

Aaaaahhhhh… 

Hello, guys and girls.
Please, help me with this issue.

I have a workflow that deploys correctly and works fine. BUT.
I need to use mail nodes and mail actions that come up with jPLD 3.2.
So.
I modified my processdefinition.xml to correspond jPDL 3.2 version as shown below:

<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="scwf:publishwhitepaper">‍

and added mail action to one of events:

…<mail name="mailtest" to="#{notificationRecipient}">  <subject>Hello, #{notificationRecipient}</subject>  <text>Dear #{notificationRecipient}, please, do not reply to this message.</text></mail>…‍‍‍‍‍‍‍‍

This is just a test…
Okay, now because jBPM engine will send e-mails, I need to setup SMTP rules.

I looked into XMLs in ../WEB-INF/classes/alfresco folder and found that workflow-context.xml contains the following:

<!–                     –><!– jBPM Implementation –><!–                     –><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>‍‍‍‍‍‍‍‍‍‍

Well, I created package ../WEB-INF/classes/org/alfresco/repo/workflow/jbpm and put jbpm.cfg.xml into this folder. It contains only the following:

<jbpm-configuration>  <string name="jbpm.mail.smtp.host" value="localhost" />  <string name="jbpm.mail.port" value="9025" /></jbpm-configuration>‍‍‍‍‍

Well, everything looks great and I'm starting Alfresco…

And have this:

How changing version from 3.1 to 3.2 may cause this:
instance not of expected entity type: org.jbpm.graph.node.Join is not a: org.jbpm.graph.def.Node   ???


What I done wrong? What should I do to make this working?
Please, help ASAP.

Thank you very much!

Did you achieve that mail stuff in alfresco. If yes, please let me know how it would possible to send a custom email.

Post your process definition. From the limited error that you posted, it looks like you tried using a fork and join but didn't use the correct syntax in the join node.

On a slightly more related topic, why don't you just use the mail action instead of trying to change the jpdl version?

[manish17]

Thankx for ur response.

I am not using Fork and Join nodes in my workflow. I need to know how to create a custom class for sending emails and where I need to specify my custom class in the Task node. So that I can receive emails based on my custom SMTP Configurations.

Did you ever tried to obtain this information with usage of JBPMConfiguration?

Within a valid JBPMContext (e.g. a JBPM-Action), you should try something like this:

String mailHost = JBPMConfiguration.Configs.getString("jbpm.mail.smtp.host");‍
