pentaho set up to AWS Aurora ( mysql ) bastion

Question

I am trying to setup pentaho spoon to connect to AWS auora which on a vpn in AWS. I have access to AWS auora ( mysql ) through a bastion server. It is working with mysql workbench and a simple java program.

Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/estimates", "root", "xxxxxxx");
Statement stmt = conn.createStatement();
String strSelect = "select first from test_name";

ResultSet rset = stmt.executeQuery(strSelect);
int rowCount = 0;
while (rset.next()) {  
    String first = rset.getString("first");
    System.out.println(first);
    ++rowCount;
}

with pentaho this error:

Error connecting to database [t1] : org.pentaho.di.core.exception.KettleDatabaseException: 
Error occured while trying to connect to the database

Exception while loading class

I have loaded the jdbc driver in the ..\\data-integration\\lib.

What could I be missing? Or is it a problem with this version of pentaho 4.4.0-stable?

Answer 1

I used an older jdbc driver aand it worked with this version of pentaho
