javascript + java = msjs

[wolffiex]

Hi guys,
We've been working on a framework for building server-connected,
browser-based apps with java back-ends. We call our project "msjs" and
we use jQuery + Rhino on the server to build up a valid XHTML web page
and then send it down to the client, with all of the AJAX callbacks in
place. msjs also has features for server-push. Here's the link:
http://openmsjs.org

The cool thing, Java-wise, is LiveConnect, which you may remember from
Netscape 4 days. It's still alive and well in Rhino, and it means you
can go like:
var queue = new java.util.concurrent.ConcurrentLinkedQueue();
while( !queue.offer({foo: 1, bar:[1,2,3]}) ){
queue.take();
}

Anyway, msjs is beyond the scope of just a Java library for CouchDB,
but we've found that it's a nice way to connect web browsers to the
stuff that Java's good at: transactional business logic, shared
mutable data structures, that kind of thing. It's packaged as a war,
so you should be able to just drop it into your existing project.

We have a tutorial that gives you an idea of what it's like to program
in msjs here: http://openmsjs.org/wiki/display/msjs/Your+first+msjs+app

We've also built a multi-host CouchDB admin tool using the system that
you can find out more about here:
http://openmsjs.org/wiki/display/msjs/Chaise

We'd love to hear from you! Thanks,
Adam Wolff

Oh, and I should have said: because msjs is all about JSON, javascript, and http, it's a great fit with CouchDB.

Hi Adam,
Looks good. I`ll give the CouchDB client a go.

I`d be interested to know why you choose Guice over Spring for your
DI.
I`ve been working on a project recently and found Guice to be a bit
lacking compared to Spring especially
with regards to transactions.

Hi Darran,

Sorry for the late reply. I do hope you'll check our stuff out.

As for Guice, I like it because it's simple and it doesn't do too much. This is just opinion, but my feeling is that people use Spring for both DI and configuration. My feeling is that DI should be done kinda before runtime, whereas configuration is a runtime thing. We use commons config for our configuration, and it works great: http://commons.apache.org/configuration/

Anyway, I hope that's not much of a rant! Best,

Adam
