can I reference session variables in jsp subroutine?

I have a function:

<%!
static void myFunction(String something)
{
String sessionVar = (String) session.getAttribute("sessionVar");
}
%>

This gives me the error:

An error occurred at line: 437 in the jsp file: /printAPchecks.jsp
session cannot be resolved

How do I reference session variables in subroutines?

You can't use the implicit session object directly in a method body. Try something like the following...

<%!

HttpSession sessionObject = session;

static void myFunction(String something)
{
    String sessionVar = (String) sessionObject.getAttribute("sessionVar");
}

%>

Open in new window

Looked promising, but I get:

An error occurred at line: 437 in the jsp file: /printAPchecks.jsp
session cannot be resolved

I typed it as you showed:

<%!
HttpSession sessionObject = session;

:

%>

do I need to import something?

@mccarl, the problem with your idea is that all concurrent users will have to share the same sessionObject.

Ah yes, my bad, forget what I have said and go with rrz@871311's approach! :)

I'm going to experiment with this a bit more and get back with results.

You know, I'm not going to get around to playing with this any time soon. I solved the problem by passing the parameters I need to the subroutine from the caller and I'm just not getting around to playing with the subroutine/session-variable notion. I'm going to close this out and thank everyone for participating!
