Re: Problem with the import java.security.*;
Hi Phani,
I can confirm that the java.security package is not supported in GWT.
Keep in mind that GWT is for Ajax application development on the
client-side, so all code gets cross-compiled from Java to obfuscated and
optimized JavaScript that can run in the browser. Therefore, you are bound
by the same browser limitations as any other Ajax framework, hence
java.security functionality not being available on the client.
What you could do to solve the unique number generation problem in the code
snippet above is have it run on the server and pass back the number to the
client through a GWT RPC call or a RequestBuilder callback.
For more information on either technique, check out the GWT docs linked
below.
GWT Developer Guide:

Hope that helps,

Hi All,
In my application i have to implement a unique number generation i.e
UUID using SecureRandom class of java.security package. Please refer
the below code.
try {
// Create a secure random number generator
SecureRandom sr = SecureRandom.getInstance(SHA1PRNG);
// Get 1024 random bits
byte[] bytes = new byte[1024/8];
sr.nextBytes(bytes);
// Create two secure number generators with the same seed
int seedByteCount = 10;
byte[] seed = sr.generateSeed(seedByteCount);
sr = SecureRandom.getInstance(SHA1PRNG);
sr.setSeed(seed);
SecureRandom sr2 = SecureRandom.getInstance(SHA1PRNG);
sr2.setSeed(seed);
} catch (NoSuchAlgorithmException e) {
}
But i'm facing a problem stating that java.security cannot be resolved
to a type. Please help me.Whether GWT doesn't support java.security
package?
Thanks in Advance,
Phani.

Re: Problem with the import java.security.*;
I do not think you can do that with GWT. Therefore I use
http://uuid-service.appspot.com though not with GWT application.
