Re: Tomcat -- JSP -- KeyPairGenerator -- Security Exception

[Michael McGrady]

I find that Tomcat has the JCE.jar without a KeyPairGenerator class.  Yet, 
when I go for KeyPairGenerator.getInstance("RSA") it works but 
KeyPairGenerator.getInstance("DH") does not.  Both jce.jar and 
sunjce_provider.jar have DH keys.  I just cannot figure what is going on 
here.  sunjce_provider.jar has KeyPairGenerator in jre/lib/ext/.  HELP! LOL!

When I am using Tomcat I get a security exception when I try to access a
