Memory leak in Ajax poll?

[niubi]

Hi all,

I´m having problems with memory leaks in a web using ajax poll and I have seen that the Ajax poll showcase in the PrimeFaces web site has a memory leak too. Is this a known bug?


I´m using primefaces-2.2.M1, Mojarra 2.0.2 (FCS b10) and Tomcat 6.0.24

Thanks in advance!

How do you understand that there is a leak?

I run the ajax poll showcase (with IE 8 or FireFox 3.6) and the memory used by the browser increase indefinitely. So if you keep the browser window open for a long period it will eat up all your resources.

Which tool are you using for profiling.

I´ve used Drip, its available here http://outofhanwell.com/ieleak/index.ph ... =Main_Page

If there really is a memory leak in poll then I'm in big trouble. Since AJAX Push isn't working in the latest PrimeFaces I'm resorting to polling. If polling also is not a valid option then ... well...

Hi bumble.bee,

I recommend you to try ICEPush http://www.icepush.org/. It's very simple to use and is more reliable than other server push technologies.

Here is a small article about this subject http://java.dzone.com/articles/icepush- ... va+Zone%29

Thanks for the suggestion. IcePush sounds like a reasonable option. I would have to use the JavaScript or jQuery / raw interface I suppose since the JSF integration is IceFaces, which I don't want to fool with (dealing with the quirks of one component library is about all I can take).

Hi bumble.bee,

ICEPush != ICEFaces. It's an independent jar file without any dependencies. Pure JDK.

Yeah, I got that part. The DZ article though lists all of the integration options and the one for JSF says it is IceFaces.

All I was saying in my previous post is that I don't want to use IceFaces so as far as integration options are concerned it looks like I'd need to use either JavaScript or jQuery.
