but it can be run.
the exception is:
java.lang.ExceptionInInitializerError:
java.lang.SecurityException: Cannot set up certs for trusted CAs: java.net.MalformedURLException: no protocol: US_export_policy.jar

at javax.crypto.Cipher.a(DashoA6275)
at javax.crypto.Cipher.getInstance(DashoA6275)
can u help me?

Answer 1

It may be the cacerts file is not appropriate (I am no expert in JCE either), but I note that when I ran my application in the external sun JDK I did not have to add certificates (the JCE is used to create NTLM authentication credentials and I provide all the required information in the program code). Also, the cacerts file under my sun jre 1.3 seems to be very similar to the one stored under my oracle home (but they are not identifical to a binary diff).
I think that this is more likely a resource load problem, as the JCE has a plugable provider interface and is likely to make heavy use loading class files and other resources by name.
I don't really have time to investigate this further. I can work around the problem by using a different authentication scheme in my application. However, since the JCE is part of the Java 1.4 specification and this spec is used, I believe, in the Oracle 10g release and I will likely have an chance to look at running my code in 10g in the next few weeks, I will post a quick note to say if the same code works there or not.
