DeclarativeWebScript and public methods

Hey this is neat! Am I wastefully re-inventing something that is already possible in DeclarativeWebScript? I have some public string manipulation methods in my DeclarativeWebScript subclass. I want to be able to call them from the javascript . AFAIK the methods are not exposed anywhere to the jav

Yeah Rhino (the JS interpreter embedded in Alfresco) has pretty good Java integration, and although there might be some overhead in JS -> Java calls, it's probably pretty quick once the JVM has warmed up (I'm assuming a lot of the bridging code would get JITted before too long).

In terms of profiling, I'd probably profile the entire Web Script and then compare the use of Javascript idioms with calls through to Java. Hopefully you'll find that the execution time is dominated by something else entirely (eg. network I/O). :wink:

You've probably already seen this, but there's more documentation on this kind of thing at:
