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

[Michael McGrady]

Also, Niall, from the same j2se I can use the KeyPairGenerator for 
Diffie-Hellman by running main through a command line, but not through 
Tomcat.  So, my reasoning is that it has to be Tomcat?  No?  I know that 
through Tomcat it seems to access SunJSSE but not through the command 
line.  What is going on is beyond me at the present.  I don't know enough 
about JSSE to sort this out, I think.  I may be wrong about the problem, 
however.

I get the same problem when tomcat uses Java 1.3.1_04 - i.e. works for RSA,
but not DH - when I switch to Java 1.4.2_01, everything is OK.
