[jira] Created: (COCOON3-4) Provide an XML generator based on Bean(s)/POJOs

Provide an XML generator based on Bean(s)/POJOs
-----------------------------------------------

                 Key: COCOON3-4
                 URL: https://issues.apache.org/jira/browse/COCOON3-4
             Project: Cocoon 3
          Issue Type: Improvement
          Components: cocoon-pipeline
    Affects Versions: 3.0.0-alpha-2
            Reporter: Simone Tripodi
            Assignee: Cocoon Developers Team
            Priority: Minor
             Fix For: 3.0.0-alpha-2


A Bean(s)/POJO(s) generator is a starter component for the pipeline that streams sax events, generated reading/intrsopecting the Object input, to an xml consumer.
It could be useful when Objects are retrieved, i.e. from a persistence engine, and they have to be streamed in an XML format to implement a Rest API.

Simone Tripodi updated COCOON3-4:
---------------------------------

    Attachment: BeanGenerator.patch

The provided patch implements a BeanGenerator, using the commons-betwixt library.
I know that one of the main scopes of cocoon3 pipeline is limiting the dependencies, but the apache's commons-betwixt already implements a SAX writer that streams xml events to a content handler.
Moreover, as reported on http://commons.apache.org/betwixt/guide/output.html (on the bottom), "SAXBeanWriter pushes events to a SAX content handler. This allows Betwixt to efficiently participate as a content generator in SAX-based pipelines such as cocoon"

Reinhard Poetz commented on COCOON3-4:
--------------------------------------

I think we should create a cocoon-pipeline-optional module that contains stuff that requires 3-party dependencies. There we should also set the scope of the dependencies to 'provided'. This prevents Maven from pulling in all libraries automatically.

Simone Tripodi commented on COCOON3-4:
--------------------------------------

Yes of course you're right and I agree with you! If this patch will be accepted as "proof of concept", once the cocoon-pipeline-optional will be created I'll create a new patch for the new package

Reinhard Poetz closed COCOON3-4.
--------------------------------

    Resolution: Fixed

Thanks for your patch. After creating a new module 'cocoon-optional' I've added it to it.
