Hello.
I'm developing a simple (read: JSP, JDBC-based, but not using EJBs, JMS, JTA or
anything fancy) application. I want to use the UUIDKeyGenerator that is bundled
with JBoss, but I am stumped at how to declare and use the UUID Key Generator.
I've got the uuidkeygenerator.sar in the deploy directory. I've set up the
code:
try {
InitialContext ic = new InitialContext();
String idFactoryName = "UUIDKeyGeneratorFactory";
// get generator factory from JNDI
try {
UUIDKeyGeneratorFactory keyGeneratorFactory =
(UUIDKeyGeneratorFactory)ic.lookup(idFactoryName);
// get generator instance
UUIDKeyGenerator idGenerator =
(UUIDKeyGenerator)keyGeneratorFactory.getKeyGenerator();
String generatedId = (String)idGenerator.generateKey();
log("Id is: " + generatedId);
} catch (Exception ex) {
log("Threw an exception: " + ex.getMessage());
}
} catch (NamingException nex) {
log("Threw a naming exception: " + nex.getExplanation());
}
I double-checked that standardjbosscmp-jdbc has the following declaration:
<unknown-pk>
<key-generator-factory>UUIDKeyGeneratorFactory</key-generator-factory>
<unknown-pk-class>java.lang.String</unknown-pk-class>
<jdbc-type>VARCHAR</jdbc-type>
<sql-type>VARCHAR(32)</sql-type>
</unknown-pk>
But when I run the program, here's the exception I get:
WebModule[/db_test]Threw an exception: UUIDKeyGeneratorFactory not found|#]
I'm obviously missing something quite fundamental. Can anyone help me out here?
Thanks,
Maya
