Hi,
I'm trying to access session from a Groovy class, but I'm not
successful.
When I have a simple script:
<%
session = request.getSession(true);
counter = session.getValue("counter")
%>
- everything is OK.
But when I have a class:
class User {
def counter = 0;
void setUser() {
session = request.getSession(true);
counter = session.getValue("counter")
}
String showCounter() {
return this.counter;
}
}
The Error message is No such property: request for class: User.
So how should I access session from the class?
You need to pass the request to your groovy class.
See for example

Hi,
thanks for a quick response. Somehow I managed it. I thought I tried this way yesterday,
but apparently I made a mistake somwhere.
Thanks,

New subject: [xwiki-users] Using parseGroovyFromPage on inherited class
Hi,
I have another problem. I want to use a class that extends a parent class and then use
parseGroovyFromPage.
But I can't work out how to do it. An example here:
---------------------------------------------------------------------
page ParentObject:
<%
class ParentObject {
def counter = 0;
def session;
void setSession(session) {
this.session = session;
}
}
%>
---------------------------------------------------------------------
page UserClass:
/* Groovy Class #* */
public class User extends ParentObject {
void setUser() {
if (session.getValue("counter") != null)
this.counter = session.getValue("counter") + 1;
else
this.counter = 1;
session.setAttribute("counter", this.counter);
}
String showCounter() {
return this.counter;
}
}
/* *# */
---------------------------------------------------------------------
script page:
#set ($groovyObject = $xwiki.parseGroovyFromPage("Include.UserClass"))
---------------------------------------------------------------------
The question is how to include the ParentObject page into UserClass page, so that
UserClass can extend the ParentObject.
Any help would be appreciated.
Thanks, Zik

Hi
I think you'll need in your User class to use
$xwiki.parseGroovyFromPage("ParentObject")
Before that you need to pass $xwiki to User class.
public class User extends ParentObject {
private xwiki = null;
void setUser() {
if (session.getValue("counter") != null)
this.counter = session.getValue("counter") + 1;
else
this.counter = 1;
session.setAttribute("counter", this.counter);
}
String showCounter() {
return this.counter;
}
public void setXwiki(xwiki)
{
this.xwiki = xwiki;
}
}

Hi,
that doesn't work.
xwiki.parseGroovyFromPage("ParentObject") returns an object of the class. I only
need to include the class, so that UserClass can extend it.
Hi
I think you'll need in your User class to use
$xwiki.parseGroovyFromPage("ParentObject")

public class User extends ParentObject {
private xwiki = null;
void setUser() {
if (session.getValue("counter") != null)
this.counter = session.getValue("counter") + 1;
else
this.counter = 1;
session.setAttribute("counter", this.counter);
}
String showCounter() {
return this.counter;
}
public void setXwiki(xwiki)
{
this.xwiki = xwiki;
}
}
