I got the PoolingDataSourceExample.java up and running using Vertica driver
easily enough.
I now need to switch to MySQL. I switched out the driver and the uri
particulars. But I am getting the exception below. Interesting enough I
expected issues with Vertica, but not MySQL. You just never know.
Exception in thread "main" java.lang.NullPointerException

My setup hasn't really changed much from the working Vertica.
Properties dbProp = new Properties();
dbProp.put("user", aUser);
dbProp.put("password", aPw);
dbProp.put("loginTimeout", "35");
dbProp.put("binaryBatchInsert", "true");
dbProp.put("autocommit", false);
String db = "jdbc:mysql://" + "localhost:3306" + "/" + aDb;
DataSource dataSource = setupDataSource(db, dbProp);
Thanks in advance.
