Show progress of running java process, even after reopening webpage -

-

i working company developing web based software j2ee.

on our webapp possible upload csv file. ive got kind of reader class reads each line , processes it. (it checks if values in each csv line valid , inserts them database). along reader counts lines read show number @ end of process.

users can upload file , click on 'process' button, after process starts. these processes can have long duration since csv files can big. when users closes webbrowser process still continues on server.

i want users let them follow progress. when close browser , log in again. guess there should kind of id attached each process, know user's process , status of progress is?

is there kind of mechanism in java can accomplish this?

the simplest way track progress process write update database table - 'jobs'. when user uploads new csv file , hits 'process', can first make entry table. process periodically writes table progress. when user logs in account can see jobs had started , progress. not cleanest approach work done. lot of things depend on specific framework. perhaps make entry table process id , there wont need update progress in table. frontend use rpc process query progress.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
