Tomcat + managing properties files -

-

we have 1 tomcat server running 2 webapps; 1 sites, , webapp eu. have functionally partitioned app & db along these lines; 1 logical instance running site, , eu site.

currently, our release process follows: - deploy 2 identical war's on tomcat, except before re-starting tomcat change properties file identify us, or eu webapp

what we'd automate whole process. i'd deploy 2 wars, without modifying properties files without changing build scripts much. suggestions how remove manual step?

if using ant build script can use filterset feature of copy command set properties. need:

  • a template property file
  • two property files (one each webapp)

your template file:

... locale = @deploy.locale@ other.stuff.int = 123 other.stuff.string = test string ...

(note @deploy.locale@ placeholder)

your property file:

... deploy.locale = ...

you eu property file:

... deploy.locale = eu ....

in ant build file can:

  1. wipe tmp directory
  2. compile project tmp directory
  3. copy template property file merging in properties
  4. wrap tmp folder war_for_us.war
  5. copy war_for_us.war in tomcat webapps directory
  6. copy template property file merging in eu properties
  7. wrap tmp folder war_for_eu.war
  8. copy war_for_eu.war in tomcat webapps directory

you can stop & start tomcat in build script. here's how copy template:

<copy todir="${tmp.dir}" overwrite="true">     <fileset dir="templates">         <include name="template.properties" />     </fileset>     <filterset filtersfile="us.properties" /> </copy> ... <copy todir="${tmp.dir}" overwrite="true">     <fileset dir="templates">         <include name="template.properties" />     </fileset>     <filterset filtersfile="eu.properties" /> </copy>

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....
