Hi Everyone,

I tried catch the Session through the SimpleTagSupport, and I could not...

But I read in the Heard First Book that the SimpleTagSupport is used in 99,99999% of the tags, (so... Should there are a method to do this, right!?)

I also beyond the Sessions, want to catch the ServletContext object

So... How can I do it?


Thanks.

Paulo Gervásio.

Hey!

I found the method:



But I cannot understand because getJspContext(); don't returns a PageContext object... Somebody knows?


Thanks.

Hi Paulo,

True, but PageContext extends JspContext

The JspContext is described like this:
JspContext serves as the base class for the PageContext class and abstracts all
information that is not specific to servlets. This allows for Simple Tag Extensions
to be used outside of the context of a request/response Servlet.


As we are using SimpleTags always in an environment that is Servlet-based (in JSPs, those are Servlets) you can safely downcast the JspContext to the PageContext object.

Regards,
Frits
