Architecture Java EE ? many ressources : database, xml -

-

i have java application , want make web app. think how make architecture of app.

in fact, have many resources, matlab, exe files , xml files , mysql database. have 3-tier architecture.

client: browser
treatment: java ee server (maybe servlet , ejb container)
data: matlab, exe files , xml files , mysql database

so, how can create application without having problem if have several clients connected sends many queries @ same time?

knowing processing calling exe , reading , writing xml files, , execute matlab.

more details

input -ressource-> output

image(query) -exe-> xml

xml -jdom-> java objects (list)

java objects -jdom-> n xml files

n xml files -jdom-> txt files

txt files -matlab-> txt files

txt files -mysql-> java objects (list)

txt files --> images (results)

this pretty broad question. keep answer @ high level , can dig deeper have more questions.

initially how structure application.

  1. pick mvc framework. pick jsf2 else fine too. view , controller layer defined here.
  2. create 3 dao classes @ bare minimum - 1 reading data xml, 1 reading data mysql, , 1 reading text files. parse xml files can use xpath , ofcourse sqls data database.
  3. create mdb asynchronously kick off exe process via jms.
  4. package application ear file.

tools can use:

  1. eclipse ide
  2. jboss-as (or other container have access to)
  3. some sort of build/packaging tool (ant, maven, etc)

i not familiar image manipulation can't comment on part. however, think need break down design various components first. that's why started listing ones think of without enough details. image query 1 of components. try create black box diagram of system each major component in & out. after start developing each of them , bet lot more folks here can more specific questions. make sense?

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....
