UUIDKeyGeneratorFactory lookup fail
This is my code to lookup the UUIDKeyGeneratorFactory in JBoss4.0.2
public static String getInitKeyGenerator()
{
String key = null;
try
{
Context initial_context = new InitialContext();
KeyGeneratorFactory kgf = (KeyGeneratorFactory)initial_context.lookup("UUIDKeyGeneratorFactory");
KeyGenerator kg = kgf.getKeyGenerator();
key = kg.generateKey().toString();
}
catch( NamingException ne )
{
ne.printStackTrace();
}
catch (Exception e)
{
e.printStackTrace();
}
return key;
}
This the exception i got :
