java - How to change Tomcats JVM version? -

-

i have java jdk 1.7.0_21 installed on debian machine (along others). have configured debain use jdk:

pi@raspberrypi ~ $ java -version java version "1.7.0_21" java(tm) se runtime environment (build 1.7.0_21-b11) java hotspot(tm) client vm (build 23.21-b01, mixed mode)

from reading notes in tomcat catalina.sh, understand tomcat server should use java_home/jre_home system variables

#   java_home       must point @ java development kit installation. #                   required run "debug" argument. # #   jre_home        must point @ java development kit installation. #                   defaults java_home if empty.

i have set proper directory. echoing variables gives following output:

pi@raspberrypi ~ $ echo $java_home /opt/oracle_java/jdk1.7.0_21/bin pi@raspberrypi ~ $ echo $jre_home /opt/oracle_java/jdk1.7.0_21/jre

the tomcat web application manager still shows 1.6.0_27-b27 jvm in use.

do have advice on how make tomcat run 1.7.0_21 jdk?

navigate directory tomcat installed, , go \bin folder (/tomcat/bin). right-click file catalina.bat, , select edit

scroll down in code until pass end of beginning “rem” comments, , insert following code pointing jdk’s root directory:

     set java_home=/opt/oracle_java/jdk1.7.0_21

save changes, , restart 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...
