Re: How to build a hudson/jenkins like live log viewer?
Guys, This works like a charm. I'm using it in in our project. Thanks once again for all your suggestions. Just a minor correction in case you are using a MultiLineLabel for nextLog. While appending Javascript in the onPostProcessTarget method, instead of: use: This is needed because .text() method removes the html formatting (i.e the br tags) added by MultiLineLabel.

Re: How to build a hudson/jenkins like live log viewer?
Hi, Check the source code of these two examples: http://www.wicket-library.com/wicket-examples/ajax/clock http://www.wicket-library.com/wicket-examples/ajax/world-clock For your task you can use MultilineLabel component to show the current content. Just refresh its model with the latest content of the file. This wont be very effective because it will re-deliver the whole file content again and again but it is the most simple way. When you become more acquaint with Wicket you can optimize it by re-delivering just the new stuff that is not already shown in the previous repaint.

Re: How to build a hudson/jenkins like live log viewer?
Thanks everybody. I finally managed to display the content of an active log
file.
As mentioned in the earlier responses, all you need is two labels.
*Markup*:
div id=logData wicket:id=logData/div
div id=nextLog wicket:id=nextLog/div
*Java*:
Create the logData label as you would normally create labels and load the
content of the log file.
Something like this:
private MultiLineLabel createLogData()
{
return new MultiLineLabel(logData, new
LoadableDetachableModelObject()
{
@Override
protected Object load()
{
try{
return FileUtils.readFiletoString(file);
}catch(Exception ex){}
return ;
}
});
}
And now the interesting component nextLog. It might look something like
this:
private Label createNextLog()
{
Label nextLog = new Label(nextLog, new
LoadableDetachableModelObject()
{
@Override
protected Object load()
{
//use a tailing api like Tailer in commons-io or may be
just java.io.RandomAccessFile?
return your 'tail' content goes here;
}
}){
// This is needed because, wicket created dynamic ids for the
nextLog component
@Override
public String getMarkupId(boolean createIfDoesNotExist)
{
return nextLog;
}
};
nextLog.add(new
AjaxSelfUpdatingTimerBehavior(Duration.seconds(REFRESH_INTERVAL))
{
@Override
protected void onPostProcessTarget(AjaxRequestTarget target)
{
/*
* We are doing the following here:
* - append the content of nextLog to logData
* - remove nextLog
* - insert nextLog after logData.
*/
target.appendJavascript(
$('#logData').append('p' + $('#nextLog').text()
+ '/p'); +
$('#nextLog').remove(); +
$(\div
id='nextLog'\).insertAfter($('#logData')););
}
});
nextLog.setOutputMarkupId(true);
return nextLog;
}
Thank you once again for each and everyone who took their time to give your
thoughts/suggestions. They were precious and I learned a lot by merely
interacting with this wonderful community.

Re: How to build a hudson/jenkins like live log viewer?
For the backend, I have the Tailer running in a Thread, and keep a reference to
it. The you can interrupt the thread as desired by calling thread.interrupt().
Some backend code you might find useful:
private Thread thread;
public void destroy() {
//set the flag to tell our listener to shutdown
stopListener();
}
public void startListener(File f) {
if(thread == null) {
//setup the listener and start the thread
TailerListener listener = new LogTailListener();
Tailer tailer = new Tailer(f, listener, 1000, true);
thread = new Thread(tailer, THREAD_NAME);
thread.start();
}
}
public void stopListener() {
thread.interrupt();
}
Interested to see your UI when you are done, please share!
cheers,
Steve

if(thread == null) {
//setup the listener and start the thread
TailerListener listener = new LogTailListener();
Tailer tailer = new Tailer(f, listener, 1000, true);
thread = new Thread(tailer, THREAD_NAME);
thread.start();
}
}
public void stopListener() {
thread.interrupt();
}
Interested to see your UI when you are done, please share!

Clint,
Thanks for this idea. Let me give a try to it.
Pondering whether the Tailer would introduce any memory leaks if we
navigate to a different page.

I'd need to look at Tailer to see how it operates. But here is how I'd
try
it (it is quick and I don't like the markup, but we'll optimize it
later:
Create a panel that looks like so (we'll call it LoggingPanel):
wicket:panel
div wicket:id=logDatalog contents/div
div wicket:id=nextLognext log call/div
/wicket:panel
Add a self updating timer behavior so the panel check the Tailer for
output, if there is data, then update the logData label with it, make
the
nextLog component be another LoggingPanel with a
SelfUpdatingTImerBehavior,
and stop the timerbehavior on the current panel.
Drawbacks are: the divs keep getting nested, so the markup isn't the
most
beautiful, so setRenderBodyOnly(true) might make it nicer.

Thanks Steve. I'll look into the commons-io Tailer.
But any idea on how to use this with wicket?

Dear wicket community,
In a project that I'm working on, I need to build a live log viewer
or
dynamic log viewer or refreshable log viewer.
Much like how hudson/jenkins displays the console output.
The idea is to dynamically display the new data added to a log file
along
with the existing content.
How to go about doing this? Please throw some light on this.
I searched about this in the web, mailing lists but couldn't find
what
I
was looking for, so I'm posting it here.
If this is asked elsewhere, kindly re-direct me to the respective
resource.

Re: How to build a hudson/jenkins like live log viewer?
Thanks Igor. You simplified it to the maximum.

a much simplified version:
div wicket:id=logDatalog contents/div
div wicket:id=nextLognext log call/div
no panel needed. add self-updating behavior to next log call and in
the callback also add
target.appendjavascript( $('#logdata).append($('#nextlog).content());
$('#nextlog').remove(); $('#logdata).insertafter($('div
id='nextlog')); )
im paraphrasing jquery here, but the is that you repaint the nextog
div and add javascript that after the repaint you move its contents to
the logdata div, and then empty the nextlog div. of course the nextlog
div should be hidden via css
