DataSourcePool in WorkflowProcess

I am trying to dynamically connect to a datasource.  I'm using the AEM archetype.

public class mystuff implements WorkflowProcess {
private static final Logger log = LoggerFactory.getLogger(mystuff.class);
@3214626
private DataSourcePool dsp;

@9944223
public void execute(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap args) throws WorkflowException {

String dataSourceName = "MYDB";
DataSource ds = null;
Connection connection = null;
try {

if (dsp == null ) {
   log.info("DataSourcePool is null");
} else {
   for(Iterator<String> it = dsp.getAllJndiDataSourceNames().iterator(); it.hasNext();) {
      String dsname = it.next();
       log.info("Found datasource " + dsname);
    }
     log.info("Using DataSourcePool service lookup to get connection pool " + dataSourceName);
     ds = (DataSource) dsp.getDataSource(dataSourceName);

No datasources are being found and no connection made.  

I have the MYDB configured just fine.  I am using it in a Servlet by doing this annotation.

@3214626(target = "(&(objectclass=javax.sql.DataSource)(datasource.name=MYDB))")
private DataSource ds;

However, i do not want to hard-code the datasource.name.  Any ideas!!??
