java - Profiling/debug JBoss AS/Seam application -


recently started developing jboss seam web application (auction site). far i've come along great, ran long loading times ( on resources javascripts/css files, pages slow ).

is there profiler jboss seam/as can see classes in memory , etc?

what reason loading times high on css/js/images files? due developing reasons haven't enabled web-cache filters offered seam yet. vm arguments

  -drebel.log=true -noverify -javaagent:"c:\program files\zeroturnaround\jrebel\jrebel.jar" -drebel.hibernate_plugin=true -drebel.seam_plugin=true -drebel.jboss_plugin=true -drebel.allow_bytecode_proxy=true  -dprogram.name="jboss 5.1 runtime" -djava.endorsed.dirs="c:\java\jboss\as5.0\lib\endorsed" -dproject.home="c:\java\jboss\as5.0\server\default\deploy\botenveiling.war" -xms1024m -xmx1024m -dsun.rmi.dgc.client.gcinterval=3600000 -dsun.rmi.dgc.server.gcinterval=3600000 -xx:+useconcmarksweepgc -xx:+cmspermgensweepingenabled -xx:+cmsclassunloadingenabled -xx:maxpermsize=512m -xverify:none

i did tweaks (removed of default applications): http://www.jaysonjc.com/programming/how-to-configure-jboss-as-production-settings-and-tuning-tips.html

i using war-explode deploy files server.

setup:

  • jboss application server 5.1
  • jboss seam 2.2.2cr1
  • jrebel
  • primefaces 1.1

system

  • intel core 2 duo e6550
  • 4 gb of memory

i wrote blog post showed interceptor can measure each method call components using.

this way can see methods use long time, , can find bugs in code. take here , scroll down second example.

you output this:

  284.94 ms   1   foobean.getrandomdroplets()   284.56 ms   1   gahbean.getrandomdroplets()   201.60 ms   2   sohbean.searchrateddoodleswithinhead()   185.94 ms   1   frobean.dosearchpopular()   157.63 ms   1   frobean.dosearchrecent()   42.34 ms   1   foobean.fetchmostrecentyodel()   41.94 ms   1   gahbean.getmostrecentyodel()   15.89 ms   1   foobean.getnoofyodels()   15.00 ms   1   gahbean.getnoofyodels()   9.14 ms   1   sohbean.mainyodels()   1.11 ms   2   sohbean.trackhoorayevent()   0.32 ms   1   frobean.reset()   0.22 ms  43   nohbean.thumbpicture()   0.03 ms  18   foobean.getmostrecentyodels()   0.01 ms   1   nohbean.profilepicture()   0.01 ms   1   frobean.settodefault()   0.01 ms   1   frobean.getrecentmarker()

second, there profiling page on seam knowledge-base, it's not really.
