ECM j2EE

[ramimoncer]

My project is to implement an ECM (J2EE) adapted to the needs of a computer services company.
The features of this system are managing versioning, DMS, workflow, project management and CRM all integrated into one interface (portal).

First, I have to design the technical architecture by describing the different components.
I have the possibility  to use the various ECM systems like Alfresco, Nuxeo, exo DMS but the system must be the most suitable to each functionality (versioning, workflow ….).

Second, I have to deploy the assembly into the portal.

Can you help me with your suggestions or some useful documents.
Thank you and sorry for my bad English.

You need to ask more detailed questions.   Alfresco most obviously fits as part of  your DMS, Versioning and Workflow needs.

May or may not be useful for your CRM or Project Management requirements.

Its is a perfect matching, of course Alfresco is bulit on Spring (J2ee) which has huge support. The technology stack it self is open for integration, my suggestion is go ahead with alfresco.
If you have any doubts in integration, post it here.
