[opencms-dev] Concept Problems of Static Export

[jose.mato at ieuskadi.com]

Well, I've been investigating in how to do the indexes directly from the
Vfs. Can you explain how can I do that?

You can do either. I only export images, binaries (Docs and PDFs), and a
few static HTML or text files. Use the flag in
$CATALINA_HOME/webapps/opencms/WEB-INF/config/opencms.properties to set
the default behavior. I believe that by default, everything is exported.

Look for the flag 'staticexport.enabled' and read the comments.

The Lucene module indexes the VFS, not the exported files. You can
basically configure it to search anything that is stored inside of
OpenCMS, regardless of whether or not it is exported.

FYI, all of my machines have staticexport.enabled=false -- and I
developed the Lucene module that way.

JSPs are always (unless configured differently) compiled into bytecode
the first time they are run, which is why the servlet engine takes so
much longer the first time you hit it after restarting. As bytecodes,
though, all the logic is preserved. it's more like running a Java app
than storing a static HTML file.

If you EXPORT, then during the export process, all JSPs are run and the
results (that is, just the HTML) are written to a static HTML-only file.
That means, as you guessed, that conditional logic, user dependancies,
etc. gets ignored.

I would recommend:
- Set staticexport.enabled=false (make sure you restart after setting this)
- Read through the README file in Lucene 1.4 (or 1.3) for instructions
on how to set it up. If you are still stuck on #2, post to the list.
- Manually set the staticExport=true property on files you want to have
exported.

I found this to be the most difficult step in learning OpenCms.

I hope this clears things up at least a little.
