c - How to find every java process? -

-

is possible somehow find every running java process? need processid of java processes.

if install java developement kit, there exe called jps.rexe. if run exe finds every running java processes , lists processid. need same, written in c. jps.exe requires java developement kit installed.

also note there 2 scenarios:
- java.exe or javaw.exe (there more) process starts reuired process, in case "easy" find java processes.
- second 1 more complicated. application started, components or features requires java, , there no java.exe or javaw.exe process running, application still uses jre.

hopefully clear, want.

does have have idea how this?

thanks in advance!

(take comment unfortunately long, post answer.) providing links stumbled upon looking answer:

as using jre file means having open, sysinternals tool handle might helpful. seems use windows object manager able find open files (by path fragment) , associated processes.

the promising c source code related object manager found unfortunately seems quite outdated (1997). @ least key function ntquerydirectoryobject used there still exists although "has no associated import library or header file". might still possible make use of c code.

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
