java - How to correct change encoding of post query? -

-

when send post page without setcharacterencoding on server-side, фыв. setcharacterencoding(utf-8), ыва. how correct change character encoding of post query?

p.s.: read data servletinputstream.

code below.

dopost req.setcharacterencoding("utf-8"); bufferedreader r = new bufferedreader(new inputstreamreader(req.getinputstream())); string line; while ((line = r.readline()) != null) {     system.out.println(line); } 

bufferedreader r = new bufferedreader(     new inputstreamreader(req.getinputstream(), standardcharsets.utf_8));

with getinputstream have binary data without encoding. hence binary-to-text bridging class inputstreamreader needs correct encoding. otherwise uses system default system.getproperty("file.encoding").

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'm getting error seems occur on machines running windows server 2012 . application written .net 4.0 environment. hypothesis in .net 4.5 isn't playing nicely application. have no other ideas. the application designed create pdf files. calling multiple instances of itself. main application call exe file set of parameters indicate pdf files create. in way can call multiple exe files, speeding process. testing purposes, can disable calls outside programs changing setting create pdf files same program, more slowly. the pdf files saved onto local hard drive. user should have access local drives , administrator privileges. there no hidden folders. as main application goes call new instance of itself, crash. see picture below. either can't use exe file, or can't write local drive. i'm not sure which; if need create log will, can determine if application can't call exe file or if application can't write local drive. however, if run same application adm...
