The Java Cryptography Extension (JCE) is encountering runtime errors through Eclipse (Helios Release 1) on Mac. Using Mac OS X 10.6 64-bit, with Java 1.6 on the command line, I can load the "DH" algorithm from the JCE extension with no issues (see below).  However, from a plain vanilla project in Eclipse, this same code will compile correctly but will throw a NoSuchAlgorithmException at runtime. 

import java.security.*;
import javax.crypto.*;
class JCETest{
    public static void main(String[] arg){
        try {
            KeyPairGenerator myKpairGen=KeyPairGenerator.getInstance("DH");
            KeyAgreement myKeyAgree=KeyAgreement.getInstance("DH");
        } catch(java.security.NoSuchAlgorithmException e) {
            System.out.println(e); 
        }
    }
}

This problem largely precludes the use of this extension through Eclipse on Mac OSX (other common algorithms fail as well in the same way) - this example runs without error on Eclipse in Windows (Helios release 2) - is this a problem with Helios Release 1? Or with Mac OS X and its flavor of Java?

On Mac, I have tried the following without success:
(a) Under 'Installed JREs' in Eclipse preferences, altering the jce.jar location to its real location on disk (the automatically selected location from the Java frameworks was a linked file)
(b) Added jce.jar as a runtime classpath library

Reproducible: Always

Steps to Reproduce:
1. On Mac OS X, Helios Release 1, create a new Java project
2. Create a JCETest class with the above contents
3. Run the program - code compiles, but the NoSuchAlgorithmException is encountered. This same class compiles and runs without error from the command line
