Java EE stop application programmatically -

-

i'm part of project rewrite se application in ee. we're using jboss 7.1.3 our supported application server, trying minimize specific code in interest of portability.

a little background on our application...it accepts processing requests systems (mdb/webservice) , fulfills request interfacing number of other systems. system processing auditing database driven.

current functionality in existing application application shuts down in event of database connection loss prevent unaudited processing. so, i've been looking around see if there standard way of recreating functionality in portable way. guess i'm wondering if there's standard way of stopping application programatically within application or if have thoughts on providing similar functionality.

so far i've seen there may ways hook jboss via jmx , undeploy application or possibly stop mdb delivery...but i'm concerned portability since specific. i'm not concerned portability across ass across different versions of as...since process these actions seems have changed on different jboss releases.

when stop app mean system.exit(0) ? can in jboss/ ee code long app being run yours (not shared jboss)

if shared (by other apps in company or shared provider)

  1. send error response clients serve
  2. write log file , if succeeds continue servicing (log can transferred database - wont work if db has latest time)
  3. use connection pooling maintain data base connections -> suggestion keep better. can use alternate data base if main not reachable. again depends on business / particular situation
  4. to portable , responsive - respond null/ empty set. have status screen -> way of telling clients/ support of status of app , or events (like db or other resource not available time date-time). implementation: each api function first have aop intersect handle in common way.

if want un-deploy can have basic design of 1 abstract class , version each app server/ app server variant. once on app server hardly think changing or adding more, often. maybe can suggest oracle future jsr / feature of web/ ejb application

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2

i need place custom knob image shadow uislider. far have image of 38x38, of there region defines shadow of knob. now while using image, when slide knob extreme ends actual knob not able cover end points, hence end points visible under transparent region of knob image this code using customize uislider uiimage *slidebtimg = [uiimage imagenamed:sliderknobimg]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatenormal]; [self.ratingslider setthumbimage:slidebtimg forstate:uicontrolstatehighlighted]; how can implement custom knob shadow beneath it, covering end points?? look inside uislider.h , there methods let customize slider knob , track needed.
