Did you put it in lib/ext of the JRE? And I assume you are aware that JDK 1.4.1 ships with a fairly complete JCE provider.

Thanks peter for replying but I have already tried what you told.
I even tried by putting the jar file in both (jsdk\jre\lib\ext and also in programs\java\jre\lib\ext) and is still not working.
Plz help.
Also I am aware that SUNJce is quite sufficient but I want to use BC for generating self signed there some other way without using keytool?

I know you posted this a while ago, but if you're still interested... You can do all this (and more!) programmatically. I have some sample code below:

Now if you also want to verify a signed jar file (say one that you signed with that certificate from before), then my code below will help with that. Hope this helps someone!
I agree. Here's the link:
