You may use a servlet context listener...

Get the spring applicationContext and add the Bayuex Service been to it
when it context is initialized

I haven't tried this myself, but take a look into the Spring interface
ServletContextAwarehttp://static.springsource.org/spring/docs/2.5.x/api/org/springframework/web/context/ServletContextAware.htmlit
may shed some light to achieve what you want.

If you are starting your Job from a Web Request, initialize your Bayeaux
service (as Rodolfo mentioned) and pass that to your processing Job (Your
Job doesn't  have to be WebApi aware) as Rodolfo said, Bauyeaux is meant to
be used a messaging API.

using cometd with threads

2010-08-02 Thread fachhoch

I was looking into cometd , I tried the example it worked for me.I havea
new requirement ,
I have to update a panel in my page if a job running   seperately in a
thread has finished processing.


for example user clicks a link, this starts a job in a thread 
asychronously.  This job might take several days , when this user  logs in
back and if the   job is completed I want to show the user that the job is
completed,
 in my case a thread   has to publish to a channel  is this possible ?

Yes, the code is designed to be thread safe.

Re: using cometd with threads

How are you getting the Bayeux service?

It is alright to think of the Bayeux service as a messaging api, that
jumps across your various layers (from the service to the javascript
client). As long as you remember you can't trust the javascript clients
(malicious users), you are fine.

You can get it from the ServletContext:

getServletContext().getAttribute(BayeuxServer.ATTRIBUTE);
