Error executing Quant in MAC OSX with java vera 7 update 60

[francisco.sal...@gmail.com]

hi
I’m new to this Quant package. I tried to execute ToM_Strategy, as reccomended in the program guide, but I got this:


Exception in thread "main" java.lang.UnsupportedClassVersionError: examples/ToM/ToM_Strategy :

do any of you tried to execute it on a Mac with success?

thanks

Hello,
Are u sure you are running java 7 as a system java? Can you try to type java -version before calling ToM stratrgy? And report me the result? Thank you
Ps: I tried it on Mac and no issues.
Bye

I did an update to the java runtime and it verified as Java version 7 update 60. But using the command java -version on the terminal this is what says:


java version "1.6.0_65"
Java(TM) SE Runtime Environment (build 1.6.0_65-b14-462-11M4609)
Java HotSpot(TM) 64-Bit Server VM (build 20.65-b04-462, mixed mode)

Going to my System preferences Java runtime says 1.7.0_60
so I’m a bit confused. I guess that my csh terminal uses a different java version( ?).
Actually I’m trying to solve this incongruency.

SOLVED!

The problem was the update of the java plugin doesn’t update system Java. In order to do this we have to download the most recent JDK

http://www.oracle.com/technetwork/java/javase/downloads/index.html

now it shows:

java version "1.8.0_05"
Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)


If still doesn’t work, follow the instructions at

regards and thank you for pointing me the origin of the problem.
