Comments on: BEA & Ajax: Bringing BEA WebLogic Portal up to speed with JSON-RPC http://www.blog.dannynet.net/archives/25 Pondering Programming and Poetry Thu, 28 Aug 2008 22:57:42 +0000 http://wordpress.org/?v=2.6 By: Danny http://www.blog.dannynet.net/archives/25#comment-83181 Danny Fri, 05 Oct 2007 07:10:54 +0000 http://www.blog.dannynet.net/?p=25#comment-83181 Trebor, Without looking at your code it's difficult to say what the problem is. If I remember correctly (it's been almost 2 years since I wrote this, time flies...) the pageflow vars are stored on the session under some BEA specific key. And if they're on the session, you wouldn't expect them to just disappear between calls. So maybe, in the Ajax call, they can't be found because another key is being used? But again, I'm guessing here. Have you searched the BEA forums? Danny Trebor,

Do you know something about this? Thanks in advance. Hey Danny,

I’ve been using ajax, with prototype library, and it works very well, however I’m having problems with my pageflow vars, all they get null when an ajax request is invoqued.

Do you know something about this?

Thanks in advance.

The best way is to use to get the appname into a servlet string. (It will ask if you want to import the class, make sure you choose com.bea.p13n.management.ApplicationHelper). Then you can use jsonrpc = new JSONRpcClient("//JSON-RPC"); It’s in your application name Cal…. make sure that you are using the correct app name when initializing your jsonrpc object.
