I was now trying out the security sample that comes with Axis2 std dist.
I am getting the following exception.
Have anyone come across similar exception.
Digging into the code source I find the place where the null pointer is
being thrown....
MessageDigest md5 = null;
try {
md5 = MessageDigest.getInstance("MD5");
} catch (NoSuchAlgorithmException e) {
//System.out.println("Error: " + e);
//todo heve to be properly handle
}
md5.update(sb.toString().getBytes());
md5 is null.
If I create a simple java class with just a single statement of
MessageDigest.getInstance("MD5");
everything works fine.
Any idea why MessageDigest.getInstance("MD5") might be returning a null?
Exception in thread "main" java.lang.NullPointerException

Hm m ... very strange ... this is exactly the way we have configuration
in the security sample shipped with axis2-1.0-std-bin distro (Except for
the fact that you will have to include the sec.properties file in the
classpath, and if not it will throw an exception).
Did you try the security sample in axis2-1.0-std-bin ?
Thanks,
