you can put the initialization of cryptography classes in the init(...)
method of YourServlet, and in the "Servlet-declarition" of
YourServlet in webapps/yourapp0/WEB-INF/web.xml, you can
add something like the following:
1

it will ask the container to initialize that "Servlet-declarition" of
YourServlet
at the starting-period of container.

you also can use "random seed" to seach in:

make an initialization servlet that gets loaded when your application starts
up and make it use whatever methods are needed to start the JCE.

I guessed as much! How do I force it to happen at startup?

It think that tomcat is slow on first use. It's a ranodimizer of some sort,
that get's initialized when first calling a servlet.

It's the SecureRandom initialization.  You could just force such an
initialization at startup so that startup has a bit of a slowdown, but then
it runs fast the rest of the time.

Hi!

I have successfully built a servlet that uses JCE to encrypt data and
deployed it under JBoss Tomcat 2.4.1-3.2.2.

The very first access is VERY slow as the cryptography classes do some sort
of initialisation. I don't know what.

Subsequent actions seem very quick.

Is this to be expected? Can I speed it up? Can I get this initialisation to
take place at start-up before a user accesses the servlet?

Gerry
