Article: Integrating Java Content Repository and Spring

Alfresco also very good one among those,as i used alfresco extensively,it also offers all levels support and spring,hibernate were integrated.From UI point of view it uses JSF so i suggest alfresco product while choosing among the JSR-170 Content repository implementations.

Thanks,

Hi Floyd,

Can you tell me how have you clustered JackRabbit? Do you use the new clustering capabilities? If not then how are things synchronized across nodes within the cluster.

Also do you use a transactional back-end storage for the content repository and if so how have you and your team overcome the apparent lack of transactional integrity inherent in the design and implementation? Transaction chopping via component-resource partitioning (no sharing), chaining of execution units across threads, incorrect transaction patterns such as writes without reads (lost updates),....

kind regards,

William

The problem I have with Alfresco is that it is a product that happens to use its own JCR implementation for content management. It is not a JCR implementation that one could easily integrate and embed within an existing application. The last time I looked you could not even create a repository object without first creating a explicit static code dependency on Spring - you needed to access the repository via an application context. It all seems so dependent on the product packaging and deployment (web application).

regards, William

The following blog entries are all based on transactional analysis work I recently performed for a customer that was having repository corruption issues in the pre-production phase of a project based on JackRabbit.

In the importFile springify sample, I think this line
return (Node) execute(new JcrCallback() {
should be
return (Node) template.execute(new JcrCallback() {

Correct me if I'm wrong.

Thanks,
Paul.

Yes, you are right Paul. Thanks for the correction.

Hi guys, I'm the "Spring Extension JCR" committer.
I would announce to you that the original JCR Module was migrated to the new Spring Extension infrastructure. I've recently released a new version of this module currently 0.9!
