Update number of login users in all user's page when new user login
Hi, i wanted to have the number of login users to be shown on all user's screen. This means, once a new user login, the number of login users shows on other active user's screen will be updated. Let say there are 2 sessions is currently log in into my application. session.getSessionId() == [bm1pgdr1y9hf] session.getSessionId() == [198y9m0etdvpj] When the first user [bm1pgdr1y9hf] login, i want to update the page to show 'Logged on users:1' in [bm1pgdr1y9hf] 's homepage. When the second user [198y9m0etdvpj] login, i want to update the page to show 'Logged on users:2' in both [bm1pgdr1y9hf] and [198y9m0etdvpj] 's homepage. How can I update [bm1pgdr1y9hf] 's homepage after the second user [198y9m0etdvpj] login?

Re: Get all sessions
Hi Jonathan and Peter, thanks alot for your reply, i tried to get the
sessions by using the
IRequestLogger as suggest by Jonathan . It do really helps.
IRequestLogger requestLogger = Application.get().getRequestLogger();
SessionData[] sessions= requestLogger.getLiveSessions();
System.out.println("The number of Live Sessions in my application is
["+sessions.length+"]");
Here is my second question, let say there are 2 sessions is currently log in
into my application.
session.getSessionId() == [bm1pgdr1y9hf]
session.getSessionId() == [198y9m0etdvpj]
When the first user [bm1pgdr1y9hf] login, i want to update the page to show
'Logged on users:1'
in [bm1pgdr1y9hf] 's homepage.
When the second user [198y9m0etdvpj] login, i want to update the page to
show 'Logged on users:2'
in both [bm1pgdr1y9hf] and [198y9m0etdvpj] 's homepage.
How can I update [bm1pgdr1y9hf] 's homepage after the second user
[198y9m0etdvpj] login?
Thanks alot again for your replies

Get all sessions
Hi, Is there any methods or functions in wicket that can give me numbers of users/sessions that is currently active and viewing/opening a page? I've been googling and read on the API, still cannot get any clues and unable to work it out.. Can i get number of sessions from my application by using ISessionStore or HttpSessions, since the session will be keep in HttpSessions.. I do really appreciate your reply..

Re: Broken link when trying to navigate to other page with another tab while 1 page is still loading
Thanx Johan for reply,
"Cant you do something with a shared resource and then push a bit more
data in the url? "
After i read your suggestion, i tried to study more into
DynamicImageResource, BufferedDynamicImageResource,Image class..
Still, I unable to get what do you mean by "push a bit more
data in the url" ..
Can you please show me some example on how to amend it? I really did crack
my head on that but yet still couldn't get the solution, the image broken
link still exist..it is my nightmare..
While searching and trying to get the solution for this, i saw this link:
http://cwiki.apache.org/WICKET/how-to-create-dynamic-image-overlays.html
This is to create the nodes for a tress, and the nodes will be overlay, do
you think this could help?
Is there anywhere for me to trace what data is currently been add to
Resource?
Plz...
Eunice

Broken link when trying to navigate to other page with another tab while 1 page is still loading
Hai,
I am trying to develop an application that going to display several charts
in 1 page. The coding as below:
public class JFreeChartImage extends Image {
private int width;
private int height;
public JFreeChartImage(String id, JFreeChart chart, int width, int
height){
super(id, new Model(chart));
this.width = width;
this.height = height;
}
@Override
protected Resource getImageResource() {
return new DynamicImageResource(){
@Override
protected byte[] getImageData() {
JFreeChart chart =
(JFreeChart)getModelObject();
return toImageData(chart.createBufferedImage(width,
height));
}
@Override
protected void setHeaders(WebResponse response) {
if (isCacheable()) {
super.setHeaders(response);
} else {
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
}
}
};
}
}
while this i am loading Page A , i failed to load Page B from my application
in different tab , where Page B is also consist of different charts, it
shows page expired or sometimes show broken link icon.
For Page A, coding for Page A will be exeuted, then will get the
JFreeChartImage class to invoke the getImageResource() method but not the
getImageData(). --> Lead to broken link
For Page B, Coding for page B will be executed, then will get the
JFreeChartImage class to invoke the getImageResource()and finally the
getImageData().
Is it because the chart for Page A in getImageResource() that loaded earlier
been override by Charts from Page B, if yes how can I fix this in order to
show the charts for both page?
Is this the nature of getImageData that only will in invoke after loading
all other pages?
Is anyone face this issue before? Pls help..
Thanx alot..
