[opencms-dev] CmsLinkManager, OpenCms / WebLogic portal integration

[Jason Trump]

Hi Robert,

We (my team and I) have a partial implementation of the WebLogic SPI for
OpenCms written.

I hope to be able to publish much of the code I write as open source,
but I am waiting for the necessary approval from my client (since they
own the code that I write) and from my employer.  Of course I have
presented the strong case that publishing the code is in the client's
best interest.  Hopefully I will have something to share with you soon.

Until then, I can at least discuss how we got things working, if that is
helpful.  Once I get the approval, perhaps we can post some code to the
list or elsewhere so that both of us don't have to cover all of the same
ground.  Have you made much progress?  Here is what we have
accomplished:

What is working:  weblogic content management tags like <cm:getNode> and
<cm:getProperty> retrieve data from the OpenCms VFS, and content
servlets like ShowPropertyServlet can retrieve data from the VFS.   You
can browse the contents of the OpenCms repository in the weblogic portal
admin application, and see property values on both folders and files. 

What isn't working:  We haven't integrated the search features yet, so
the <cm:search> tag and content placeholders don't work.  Also
hyperlinks created in OpenCms documents (using the <cms:link> tag)
aren't correctly translated into links that work in the portal -- this
is what I was getting at in my first email to the list.  We are actively
working on both of these features.

I have yet to get OpenCms static export to work at all when running in
WebLogic.  I would like to see this feature work, but if not, I suppose
we can just leave it disabled and settle for the numerous caching
features already built in to WebLogic portal.

We have not implemented (and don't plan to implement) any sort of
write-access from weblogic, so we can't use the weblogic portal admin
app to change anything in the OpenCms repository.  Someday I would like
to implement VCR "library services"; for example, moving a content node
to the "published" state in WebLogic would cause the file to be
published to the Online project in OpenCms.  However, this is not a
requirement for us.
