Subject Possible contribution to commons: JNET
Date Mon, 28 Apr 2008 15:33:13 GMT

we developed a nice little library over at the Excalibur project called jnet

It is a common purpose lib that allows you to dynamically register own 
url handlers. Background: the jvm only allows you to set a url handler 
once, so if you want to register handling your own protocols (like 
webdav: etc.), you should be the first one doing so :) Obviously, this 
might work for standalone apps but once you're running in a webapp this 
is bound to fail.

jnet uses a technique used by other projects to circumvent this 
restriction and allows to register url handlers based on the "current 
execution context", so it's possible to have different handlers for 
different webapps while still running in the same jvm.

The first version is working although this is still a prototype and 
there is room for additions/improvement.

As Excalibur itself is not...well...very active anymore and as this is a 
general purpose stuff several projects at Apache (and in other places) 
could benefit from (Cocoon is planning to use it, Felix is definitly 
another candidate although we haven't discussed this yet etc.), commons 
seems to be the right place.

So, my question is if there is interest here and what it would take to 
get this a proper commons project?
