java - How to implement environment-specific init parameters in my tomcat application -

-

i'd able implement configuration-less deployment java application (tomcat7, spring-mvc). example, right considering creating 1 context.xml file each environment (prod, stage, dev) deploy to:

context_prod.xml  context_stage.xml  context_dev.xml context.xml (for localhost)

on each of our servers have symlink context.xml point appropriate context file (e.g. context_prod.xml). when deploy, don't have worry changing database references, keys, etc.

i feel there's better way this; perhaps 1 built spring?

spring has added functionality handle environment configuration:

http://blog.springsource.com/2011/02/11/spring-framework-3-1-m1-released/

this still seems little bit complicated me , have done asking in own spring mvc applications our logging. in dispatcherservlet configuation have line: 

<context:property-placeholder location="classpath*:/system.properties"/>  <util:properties id="mysystemproperties" location="classpath:/logging/log4j-${system.runmode}.properties" />

system.runmode env variable created , set in catalina.sh @ startup this: setting environment variable tessdata_prefix in tomcat

i use spring el reference values want , works per environment. can see did our logging , have different logging configuration file per environment.

i use sonar plugin executes if activated in maven profile. sonar runs on every compile. the problem build fail other team members not have sonar application installed locally. pom.xml checked in team members same copy including sonar configuration, don't want them modify purpose of disabling sonar (they might inadvertently check modified copy in). please advise how configure maven (.m2/settings.xml) and/or pom.xml sonar feature can enabled/disabled local profile. here sonar configuration in each project's pom.xml: <plugin> <groupid>org.codehaus.mojo</groupid> <artifactid>sonar-maven-plugin</artifactid> <version>1.0</version> <executions> <execution> <id>make-sonar</id> <phase>compile</phase> <goals> <goal>sonar</goal> </goals> </execution> </executions> ...

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
