java - shutdown hook in tomcat (necessary) not running -


I have a long running CPU and database intensive thread (which runs on low priority), which is my Tomcat application manager by request.

I use a shutdown hook for this thread, so that if the application ceases forcibly, it can clear the database position before exiting. Works entirely in standalone mode, with Control-C and Canceling in Eclipse Console.

But when I'm undergoing Tomcat, and when I do this:

$ CATALINA_HOME / bin / shutdown.sh

I verified with debug logging I have done that the message that my chopped off is sent by Tomcat, but there is no way that the message can stop it, and the important thing is that my shutdown hook never fire. / P>

I have seen other people that people who used the reference had seen, but this would not work for me, and some questions and answers also show that the shutdown hook works for them in Tomcat.

Using Tomcat 6.0.35

I have a long running CPU and database intensive thread that runs on less commonality ) Which can be removed by an administrator request by my Tomcat application.

Why not go out of this process and do not bother with webapp, context event, shutdown, hook or any of the rot?

Shu tilt hook is a hip, and as @Stefenk says, they will not fire when you want them.

python - Assemble mpeg file unable to play in mediaplayer -

I am currently working on a school project and I think that is to gather some problems with the MPEG file I The scope of my project is: 1) Split the MPEG file into pieces of many fixed sizes. 2) Collecting some of them and leaving some part. Problem 1: When I run the file in the media player, it will play the video until it reaches that segment which I left Give it Example: Chunk = ["yui_1", "yui_2", "yui_3", "yui_5", "yui_6"] Duration of each segment: 1 second * If you think I have left the "yui_4" section. * If I went to collect all the parts except "yui_4", then the video will play the first 2 seconds before being hanged throughout the period. Problem 2: When I gather the first part off the part, it is unable to run the full MPEG file is. Duration of each piece: 1 second Example: wheel = ["yui_2", "yui_3", "yui_4", "yui_5", "yui_6"...

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
