java scripting inside a bundle

[Lance Frohman <lf...@gmail.com>]

Does anyone have experience using the javax.script scripting inside a
bundle?
Normally you can add the jar(s) for any script language (ruby, python, ...)
to
the class path, and the scripting is available from

new ScriptEngineManager().getEngineByExtension(extension)

(extension is "rb" for ruby, "py" for python, ...)
without doing anything else.

but this does not work when the script jars are inside a bundle (in the
bundle classpath).

Thanks,
Lance

Lance:
You might also want to look at Apache Sling's scripting support. After
installing a few bundles (I'd need to test to be sure, but my guess is
its probably 3 or 4), you can get a ScriptEngineManager from the OSGi
service registry.

If you have questions about this approach, probably better to post
them on the sling-users mailing list.

Justin

Lance:

the underlying problem is that
http://download.oracle.com/javase/6/docs/api/javax/script/ScriptEngineManager.html

is using spi
http://download.oracle.com/javase/6/docs/technotes/guides/jar/jar.html#Service%20Provider

which is to be supported soon in osgi (page 145):
http://www.osgi.org/download/osgi-early-draft-2011-09.pdf

in my case, I activate script engine in the osgi host embedder,
http://felix.apache.org/site/apache-felix-framework-launching-and-embedding.html

and access it via TCCL
http://njbartlett.name/2010/08/30/osgi-readiness-loading-classes.html

to avoid the issue.

Andrei.
