Hi all! I have done a PoC for enabling Ruby subclassing of Java classes on the Dalvik VM on Android. The issue is tracked at http://jira.codehaus.org/browse/JRUBY-6883 and the PoC is in the JRUBY-6883 branch.
Knowing that it works, I'd like to discuss how best to implement/organise this. I expect that the JRuby project would like to keep Dalvik specific parts out of the JRuby source. Is this right? The Ruboto project will probably want to improve on the feature with more frequent iterations that the JRuby project (just a guess from historic release cycles), so it figures that the Dalvik specific parts probably should be placed in the Ruboto project. Ruboto has a step during build where we customise the JRuby jars, and we could add the translation there. I am not sure how we would do this, but it is important that we keep all improvements done by the JRuby project, so we do not want a separate implementation of the whole JavaProxyClassFactory. We only want to add the translation step. One important thing to keep in mind is that JRuby can be loaded using a separate class loader, so classes in Ruboto may not be visible to JRuby. Another thing is that currently we are using the file system to store and load the classes, so we need a valid file system path that is best determined by the running Android application. In the PoC we set a system property to both indicate that we want byte code translation and where to store the temporary class files. Any thoughts on this is welcome. This is a very big step for the Ruboto project, and we want to do it right. -- Uwe Kubosch http://ruboto.org/ --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email
