Subject Re: adding features to Status servlet
Date Mon, 03 Jan 2005 19:36:20 GMT
So which way would be best/better to proceed?  Since mladen has his
apr-java stuff, would it make sense to do this?

1. write native windows dll
2. write apr component
3. use apr-java to wrap apr
4. wrap apr-java with mbeans

or

1. write apr component to call system level API
2. use apr-java to wrap apr
3. wrap apr-java with mbeans

or

something completely different?
