RE: Tomcat -- JSP -- KeyPairGenerator -- Security Exception

[Michael McGrady]

In fact I am now using 1.4.2_04, the newest and bestest.  In the 
sunjce_provider jar, which is in jre/lib/ext, there is definitely a 
DHKeyPairGenerator, so I assume that it just is not found.  Why not is 
beyond me.  It is found from the command line.  I can run classes which 
reference KeyPairGenerator.getInstance("DH") from the command line but not 
through Tomcat.  How strange.  Unfortunately, the people at Tomcat user and 
Tomcat developer have nothing to say on the issue.

Does it work with 1.4.2?

1.4.1 had some CA Cert expiration issues recently. Yeah, it sounds completely
unrelated, but if Resin 2 comes with the more recent stuff, I can\'t help but
wonder if this is at least in the right part of town.
