java - Tomcat Container Managed SSO Valve and Spring Security -

-

we have on dozen legacy web applications (each own app contexts) use tomcat's container managed security simple form-based authentication. use tomcat's single sign on valve allow authenticated users jump between web apps without need of re-authenticating. developing new web applications using spring security framework.

is possible users authenticated via new spring security apps able jump older legacy (non-spring) apps without need of re-authenticating? way bridge spring security tomcat sso valve?

i prefer avoid making changes legacy web apps, understand if doesn't seem possible.

you able using j2eepreauthenticatedprocessingfilter: http://static.springsource.org/spring-security/site/docs/3.2.x/reference/htmlsingle/#d4e2766

please note: when tomcat sso configured provides java ee authentication web application. means application transparent if authenticated form authentication or tomcat sso. java ee authentication. so, need use j2eepreauthenticatedprocessingfilter able use java ee authentication provided tomcat.

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...
