java - Start tomcat7:run maven plugin within eclipse and debug -

-

i want debug webapp in eclipse. point tomcat , webapp ran inside of eclipse in debug mode, breakpoints in webapp code have no effect.

details
webapp maven artifact , use m2e plugin in eclipse bridge between maven , eclipse.

i've managed start tomcat server within eclipse. webapp started in tomcat nicely, in debug mode if choose so:

  • in eclipse, right-click project
  • run > maven build... (not "maven build")
  • a window opens. in text field "goals", enter "tomcat7:run"
  • click apply
  • click run

the tomcat server starts running , stdlog printed window within eclipse. can stop conveniently , start again in debug mode. far, that's want , expect.

problem
set breakpoint in code of webapp , restart tomcat in debug mode within eclipse. now, breakpoint isn't active: doesn't have little tickmark active breakpoints have , know code executed, doesn't stop @ breakpoint.

there can 2 ways fix , need 1 or both of them. open run configuration, then

problem+solution 1 (fork)
if tomcat forked in vm, need add parameter forkmode value of never. allows eclipse "look through" tomcat's vm , set breakpoints there.

problem+solution 2 (source)
in setups maven parent , child artifacts, can happen eclipse not aware source of child project belong webapp. symptom of execution stopped @ breakpoint, eclipse not automatically jump source location , instead tells source unknown.
solve this, need add source of child project run configuratuon: in run configuration, go source > add... > java project , pick relevant projects contain source code might want debug.

i want check scene image against 2 train images. that, detect features , compute descriptors of both training images. before detecting, computing , matching scene image, delete matches of train1 , train2. because these matches won't facilitate matching of scene image train1 , train2. so, match train1 train2 , vector of matches trainidx , queryidx. how can delete these matches in keypoints-vector , descriptor matrix of train1 , train2? best regards, dwi i have done below: std::vector<cv::keypoint> keypoints[2]; cv::mat descriptor[2]; std::vector< cv::dmatch > matches; /* write code generate keypoints, descriptors , matches here... keypoint[0] -> train image 1 keypoints keypoint[1] -> train image 2 keypoints descriptor[0] -> train image 1 descriptors descriptor[1] -> train image 2 descriptors matches -> matched between train image 1 , 2 */ // logic keep unmatched keypoints , corresponding descriptor...

i used nvidia sdk bitonic sort , works great me. 32 bits (uint) need ulong keys. have typically 2^14 keys @ time , power of 2. searched on not find kernel designed ulong. i tried modified nvidia sdk bitonic sort using ulong keys not work. kernel not crash after de call clenqueuendrangekernel got error : cl_invalid_command_queue can tell me how modify bitonic sort or radixsort, or can sort ulong keys? i running nvidia quadro 4000 opencl 1.1 cuda 6.5.20 full_profile used original nvidia sdk bitonicsort.cl i used"ulong" keys , value input , ouput instead of "uint" thanks helping i made work-around suit need. used 30 bits of key , 18 high bits of value sorting. changed comparators (2 lines): '#define mask 0xffffc000 // suit need from this: if( (*keya > *keyb) == dir ) this: if(((*keya > *keyb)||((*keya == *keyb)&&((*vala & mask)> (*valb & mask)))) == dir ) it works fine. but, still, it's work-a...
