Java CDI Integration

alvim

Hi!

I'd like to know if there's any plan to integrate Activiti with the Java EE 6 CDI (Context Dependency Injection) Standard - similar to the Spring integration…

If not (I couldn't find that), anyone could give us any directions/help about how could we implement this integration?

Thanks in advance and congratulations for doing such a helpful product!

Hi Paulo,

Thats currently not on our roadmap, so it'll not be coming in any release soon.
But if you are willing to look into it, the Spring integration is definitely the right place to go. The hardest part however, lies in the fact that CDI usesstandardized expressions, which might not match with the ones in Activiti.

Paulo,

I started working on this. The issue is in ACT-541. For an initial release I have the following ideas

@Inject

@StartProcess(&hellip

@BeginTask

@EndTask

The variables map for a process can be 'outjected' with the CDI '@Produces()' annotation. Using one would go like #{variables.get['varname']}

In addition I'm going to provide JSF composite components for task management, task overview, kind of what the activiti-explorer does now. These will be based on Primefaces.

I also have some ideas for a second version:

Comments?

I'm very interested in the CDI Extension for Activiti. I see there's already a JIRA Issue for this. I would like to be involved in the development of this feature.

Please let me know how I can help.

Carlos,

Great to hear. Yesterday I checked in some initial personal code in my branch It's just a start and nothing official (yet, I hope)

My (unfortunately many) checkins were noticed by Daniel Meyer of Camunda and he started a topic in the dev forum. I'll write a blog about this CDI/JSF initialve when I feel better (got the flu) summarizing what is already in the pipeline. But in the mean time you are welcome to have a look at the code, correct me where I went astray, enhance functionality (do not duplicate efforts started by Daniel :-)) etc…

The more the merrier, less effort per individual and the quicker we have something really useful.

Login to your server and type the following to find java:

find . -iname java

This will tell you the correct path if you installed it in your home directory.

When you installed it did you pay attention to where the files were being installed?
