Hi smike...
Boolean b = (Boolean) session.getValue("check_2");

You have to type cast it back since getValue returns an Object type.

Hi smike.

In version 2.2, getValue and setValue are deprecated in favor of getAttribute and setAttribute (u could try these).

Bye... :)

hi smike...
You can use the booleanValue() method of Boolean.

e.g.

Boolean b2 = (Boolean) session.getValue("check_2");

if (b2.booleanValue()) {
}

cheers...

Hi smike...
Use the intValue() method of the Integer.  By the way try to download the Java API documentation? It lists all the available classes and methods of those classes of the Core Java.

U have a similar class named "java.lang.Integer":

int i = Integer.parseInt((session.getValue("amount")).toString());
