Hi Peter,

Thanks for your reply.

Yes when mentioning sonar I mean http://www.sonarsource.org/? .

I got the solution for this issue. This was caused because the module on which I was running the sonar was big and the build machine was very slow. I have increased the timeout value in Findbug and it worked.


Thanks,
Sandeep

Hi,

I am running sonar from Jenkins job. I am getting following exception while executing sonar. I have added Findbugs, PMD and checkStyle rules in sonar.

Can someone please explain me the reason of this error. Thanks in advance...

Thanks,

Hi Maneesh,

Thanks for the reply.

Actually, I am writing a custom Scroll pane similar to JScrollPane. I have added the ComponentListener to the view of scrollpane. But, I am not able to understand how the events will be fired.
I have added the JList in the scrollpane but it is not scrolling. Should I change the y position of the list to generate the ComponentListener callback which will readjust the scrollbar postion.

Thanks,
Sandeep

Hi,

Can someone please explain me how JScrollPane works. In JScrollPane we use ComponentListener which has the callback method which sets the scrollbar position.
Here I am not able to understand that how do we generate the event which causes the ComponentListener to readjust the scrollbar.

Thank you.
Sandeep

In this program we have two threads running

1. main thread
2. another thread t

initially main thread is started which spawns the new thread and calls the start() method of that thread.
After the start is called the new thread does not start executing immdiately it comes into ready to run state but not running.

Now main thread which is running prints 0 and finishes. Now the other thread start running and prints 1,2 3
