I think I'm on the point of being successful with my business. But I still have one question, considering the following short code and especially the uncommented snippet: (serves to retrieve and display all the items of the current session)
<?xml version="1.0"?> <xsp:page xmlns:xsp="http://apache.org/xsp"; xmlns:xsp-session="http://apache.org/xsp/session/2.0"; xmlns:xsp-request="http://apache.org/xsp/request/2.0"; create-session="true"> <xsp:structure> <xsp:include>java.util.Vector</xsp:include> </xsp:structure> <content> <xsp:logic> Object items = <xsp-session:get-attribute name="cart.items"/>; if (items == null) items = new Vector(10,5); ((Vector) items).add(<xsp-request:get-parameter name="item"/>); session.setAttribute("cart.items",items); /**************Error here: method get() and variable i are not known from Cocoon's servlet <ul> for (int i=0; i<items.size(); i++) { <li><xsp:expr>items.get(i)</xsp:expr></li> } </ul> **************/ </xsp:logic> </content> </xsp:page> Why do I receive the following two errors: Line 174, column 58: variable i not found in class org.apache.cocoon.www.mount.essai.session3_xsp Line 174, column 54: method get() not found in class java.lang.Object Is the syntax I am using here not the same as the following, which is OK? <elements> <xsp:logic> for (int i=1; i<11; i++) { <element><xsp:expr>i</xsp:expr></element> } </xsp:logic> </elements> Which is the difference between them?
