websphere - Web-based clients vs thick/rich clients? -

-

my company software solutions provider major telecommunications company. environment ibm websphere-based front-end ibm portal servers talking cluster of back-end websphere application servers providing ejb services. of portlets use our own home-grown mvc-pattern , written in jsf.

recently did proof-of-concept rich/thick-client application communicates directly ejb's on back-end servers. written using netbeans platform , uses websphere application client library establish communication ejb's.

the painful bit, getting client use secure jaas/ssl communications. but, after resolved, we've found rich client has number of advantages on web-based portal client applications we've become accustomed to:

  • enormous performance advantage (corba vs. http, cut out portal server middle man)
  • development simplified , faster due use of netbeans' visual designer , swing's robust architecture
  • the debug cycle shortened not having deploy client application test server
  • no mishmash of technologies web-based development (struts, jsf, jquery, html, jstl etc., etc.)

after enduring pain of web-based development (even jsf) while now, i've come following conclusion: rich clients aren't right every situation, when you're developing in-house intranet-based solution, you'd crazy not consider netbeans platform or eclipse rcp.

any comments/experiences rich clients vs. web clients?

one benefit lot of calculations/validations can done on client side, allows each client share in processing load of overall application.

another benefit of thick client hold state in client. makes servers stateless , can scale lot better making fault tolerance breeze.

in our case have interfaces hardware in our app, scanners on serial ports workstations, have implemented jni layer printers can have application control of print jobs our application. (invoice printing)

for startup , distribution of new software have update jar run checks file on local system against deployed date on server see if local system date. if system out of date download jar files needed , launch app. avoids users needing go web page.

i recommend this book server side patterns relate new java ee stuff.

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

php - Replacing tags in braces, even nested tags, with regex -

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
