activiti-cdi 5.7 snapshot in Maven repository

chris_joelly

Hello,

i want to try the example located under
https://svn.camunda.com/fox/trunk/demo/activiti-cdi-example-travelexpenses/
and checked it out from SVN, but it seems that i can not find the dependency
which is listed in the pom.

      <dependency>
         <groupId>org.activiti</groupId>
         <artifactId>activiti-cdi</artifactId>
         <version>5.7-SNAPSHOT</version>
      </dependency>
‍‍‍‍‍‍‍

is there a different repository available were i can find the snapsot builds?

thanks

i adapted the example to use activiti-cdi 5.6, and i deployed the app in Glassfish 3.1,
but it seems that the LocalProcessEngineLookup bean can not be found.

after debugging i found out that the ProgrammaticBeanLookup class asks the
BeanManager for "interface org.activiti.cdi.impl.ProcessEngineLookup" but is
not able to get one:

The BeanManager however seems to know the bean LocalProcessEngineLookup and
the Activiti CDI annotations, so it is not that bad.

can anybody point me to the right direction why it is not possible for the BeanManager to find the

thanks in advance

is there a different repository available were i can find the snapsot builds?

http://fox.camunda.com/mvn/

oh, can you change 0.7 in the subject of your posts to 5.7?

i tried the example now with 5.7-SNAPSHOT, but no luck. Same behavior that CDI BeanManager is not able to
find an instance of ProcessEngineLookup

anyway… META-INF/beans.xml lists LocalProcessEngineLookup…

yuanqixun

Today, version5.7 will be published, I wait for it, right?

chris_joelly

Yes. i wait for it. but it is still the same behavior. either it is simply not working in Glassfish,
or i am doing something wrong with that example application.

andregs

I'm having the same issue here. How did you solve that?

Thanks,

Hi guys,

first off, thanks for trying out activiti-cdi and reporting back.

There has been some confusion around enabling an implementation of the ProcessEngineLoookup SPI (like for instance LocalProcessEngineLookup).
I hope to have resolved that with:
http://jira.codehaus.org/browse/ACT-1055

Currently we look up an implementation of ProcessEngineLookup on reception of the AfterDeploymentValidation event from the container. We have a set of implementations which are all marked @Alternative (i.e. disabled)

When using activiti-cdi, one has to "enable" one of these implementations (or provide a different one, for that matter).

There is a couple of problems with this:

Per CDI-spec, one cannot enable an @Alternative Bean Class form a different bean archive. However, the notion of bean archive is container-specific, for example, weld-servlet uses a "flat" deployment (ie. all bean archives are merged into one big bean archive, while containers like Jboss 7 use a hierarchical bean archive structure mirroring the deployment structure of the container.) The consequence is that one has to use a different strategy for enabling a ProcessEngineLookup implemenation on Tomcat and Jboss AS 6 than on Jboss AS 7. (for instance)
In practice, the semantics of instantiating a bean in this phase (AfterDeploymentValidation) seem not to be well defined. In particular, not all EE-contexts seem to be setup in an application server. It seems that it is too "early" or we are on the wrong Thread, to look up beans properly at that stage.

OK, so we changed that.

Now in order to use activiti-cdi 5.8 on Glassfish 3.1 / Jboss AS 7 you can add a subclass of LocalProcessEngineLookup to your project. So you could just add the following:
<br>public class ProcessEngineConfiguration extends LocalProcessEngineLookup { <br>}<br>and that is it.

Or you can try out activiti-cdi 5.9-SNAPSHOT, where you do not have to do anything, from our camunda snapshot repository:
http://fox.camunda.com/mvn/org/activiti/activiti-cdi/
Here is an example, use the "activiti-cdi" maven profile:
https://svn.camunda.com/fox/trunk/demo/activiti5-cdi-jsf-task-management/
