Lars Trieloff closed COCOON-1908.
---------------------------------
Resolution: Later
This will be included in the reworked JCR sourcefactory that Mindquarry is
currently working on.
> Add query support to JCR source factory
> ---------------------------------------
>
> Key: COCOON-1908
> URL: http://issues.apache.org/jira/browse/COCOON-1908
> Project: Cocoon
> Issue Type: New Feature
> Components: Blocks: JCR
> Affects Versions: 2.2-dev (Current SVN)
> Reporter: Alexander Klimetschek
> Attachments: cocoon-jcr-add-query-support.patch
>
>
> The current implementation of the JCRSourceFactory is missing the support for
> JCR queries (XPath and SQL) and only allows direct paths (like
> "jcr://root/folder/file").
> I have implemented a simple query handling (see patch). It supports both
> XPath (required for JCR Level 1 compliance, thus any JCR implementation) and
> SQL (optional JCR feature). The query strings given as Source-URIs must look
> like this:
> XPath:
> jcr://xpath!//root/*
> (which maps to the xpath query "//root/*" which is passed on to the JCR Query)
> jcr://!//root/*
> (which is just a shorthand notation for the above, using Xpath)
> SQL:
> jcr://sql!select * from nt:base where jcr:path = '/root/myfile'
> (well, which maps to the sql query "select * from nt:base where jcr:path =
> '/root/myfile'")
> There is a restriction for the queries: the result to be returned must be a
> content-node with no children and some streamable content. The JCRNodeSource
> class does not allow collections to be returned. I am working on subclasses
> that will target this issue (using the XMLizable interface) but this is not
> yet finished.
> I tried to make the patch complete, including updated javadocs for the
> JCRSourceFactory class.
