activiti-cdi support for Java EE 7 / Glassfish 4.1?

[stephan_bauer]

Hi,

our appserver is Glassfish 4.1 with Java EE7.

According to the dependencies of activiti-cdi 5.6.14 - see http://mvnrepository.com/artifact/org.activiti/activiti-cdi/5.16.4 -
it is depending on jboss-javaee-6.0.

We have already tried a  lot of stuff to get activiti to inject the activiti-stuff like ProcessInstance or RuntimeService into our ServiceTask (which we tried with different Scopes including @Dependent and @BusinessProcessScoped) but we always end up with null for the injections.

Before I bother you with all our configuration and implementation details, I would like to ask the general question if anybody has got activiti-cdi working under glassfish 4.1 or if Java EE7 is generally not yet supported?

Many thanks in advance,
Stephan

Hi again,

hm. after having not received any feedback yet, I will bother you now with all the details of my setup and implementation:

I have added my servicetasks into the activiti-explorer WAR file and the Remote EJB which I want to use from the servicetask is located in another deployment unit. By the way, we are building the activiti-explorer WAR file through a maven-web project into which we have copied all activiti stuff into the right places, so that we can easily integrate our own stuff in the standard maven way.

In the pom.xml of the activiti-explorer-web module I have added the dependency for activiti-cdi:

<code>
        <dependency>
            <groupId>org.activiti</groupId>
            <artifactId>activiti-cdi</artifactId>
        </dependency>
</code>

The version comes from the parent pom.xml's dependencyManagement and is currently 5.16.4

in the activiti.cfg.xml i configured the transactionManager and processEngineConfiguration like this (as described in the activiti userguide for 5.16.4):

<code>
    <bean id="transactionManager" class="org.springframework.jndi.JndiObjectFactoryBean">
        <property name="jndiName" value="java:appserver/TransactionManager"/>
        <property name="resourceRef" value="true" />
    </bean>

    <bean id="processEngineConfiguration" class="org.activiti.cdi.CdiJtaProcessEngineConfiguration">
        <!–<property name="dataSource" ref="dataSource" />–>
        <property name="dataSourceJndiName" value="jdbc/activitiDS"/>
        <property name="transactionManager" ref="transactionManager" />
        <property name="databaseSchemaUpdate" value="true" />
        <property name="jobExecutorActivate" value="true" />
        <property name="enableDatabaseEventLogging" value="true" />
        <property name="customFormTypes">
            <list>
                <bean class="org.activiti.explorer.form.UserFormType"/>
                <bean class="org.activiti.explorer.form.ProcessDefinitionFormType"/>
                <bean class="org.activiti.explorer.form.MonthFormType"/>
            </list>
        </property>
    </bean>
</code>

The processEngineConfiguration bean also contains an LDAP config which I have cut out.

I inject the runtimeService and other activiti Beans in my ServiceTask:

<code>
@BusinessProcessScoped
public class UpdateProduktinstanzStatusServiceTask implements JavaDelegate {

    @Inject
    protected ProcessEngine processEngine;
    @Inject
    protected RepositoryService repositoryService;
    @Inject
    protected RuntimeService runtimeService;
    @Inject
    protected TaskService taskService;


    @Inject
    @ProcessInstanceId
    private String processInstanceId;

    @Inject
    private ProcessInstance processInstance;

</code>

When I fire up the activiti-explorer WAR file in my Glassfish 4.1 Server, there are no errors and I can log into activiti-explorer without errors. There are 2 warnings (see excerpt below), but they don't seem to be related to my problem.

Here is the corresponding excerpt from the startup of the processEngineConfiguration Bean:

<code>

When I start an instance of a process containing the above Servicetask as its very first action, and set a breakpoint in my execute-Method, I see, that all variables of the CDI-Injections are null. It seems, that acitiviti-cdi simply does not recognize my Servicetask to be a CDI-Bean and thus doesn't inject anything…

As already stated in my first post, this is Glassfish 4.1 with JavaEE7 and CDI 1.2(!)

Any help would be appreciated

Sorry of not being of much help, we arent using cdi ourselves. We have some limited unit tests, but we havent tested it on the versions you mention. No idea, to be honest. Let's hope someone else might have more inout :s
