Creating an external url link

[am...@yahoo.com]

 Hi,

I am trying to create a link (external) to a page, let say I have page called ViewTask.html, I know to access this page I need a url like:

http://localhost:8080/example/service=page&page=ViewTask

But if ViewTask.java has a taskId member, how do you call the page and set this required field?

Thanks in advance,
Amir

You probably want your page to implement IExternalPage, and use the  
external service to call it. This allows convenient parameter passing  
-- your activateExternalPage() method can do any necessary setup.

I spent some time grappling with parameter passing and page lifecycle  
before I figured out how useful the external service is. IMO, the  
documentation doesn't highlight it nearly enough! My own apps rarely  
use the page service; instead, they ends up mostly using the external  
service (for "entry point" pages) or the direct service (for "in  
process" pages linked/submitted from within the app). This way, every  
page has a well-defined entry point: either an activateExternalPage()  
method or a listener method, which gets rid of the great majority of  
page initialization headaches. I've liked this approach very well so  
far.

Cheers,

Paul
