How to change the Java webapp 'WEB-INF path' convention under tomcat or jetty -

-

under java webapp,

i want set /web-inf/lib d:/somepath/lib

and /web-inf/classes e:/somepath/classes

and web.xml f:/somepath/config.xml

how config these under tomcat or jetty change convention?

the specification (java™ servlet specification version 2.3) mentions standard folders:

the web application classloader must load classes web-inf/classes directory first, , library jars in web-inf/lib directory.

with tomcat or jetty cannot "out-of-box" provided functionality:

tomcat:

webappx — class loader created each web application deployed in single tomcat instance. unpacked classes , resources in /web-inf/classes directory of web application, plus classes , resources in jar files under /web-inf/lib directory of web application, made visible web application, not other ones.

jetty:

the normal configuration each web context (web application or war file) given it's own classloader, has system classloader it's parent. such classloader hierarchy normal in java, servlet specification complicates hierarchy requiring that:

classes contained within web-inf/lib or web-inf/classes have priority on classes on parent class loader. opposite of normal behaviour of java 2 class loader.

however, can:

  1. add classpaths jetty
  2. add directory tomcat classpath

cheers

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...
