retrieve table all table names from a collection using JT400

Hi
I am trying to retrieve all the table names from a
collection or library, 

Here is what i am doing
Class.forName("com.ibm.as400.access.AS400JDBCDriver");
DriverManager.getConnection("
jdbc:as400:IP/CXASHTEST;user=user;password=pass;naming=SQL;date
format=iso;time format=hms;prompt=false");

String types[] = {"TABLE"};

ResultSet rs = 
connection.getMetaData().getTables(null,null,"A",
types);
PrintDatabaseMetaDataAndResultset.printMetaDataAndRs(rs,true);
while(rs.next())
 {
        list.add(rs.getString("TABLE_NAME"));
 }
        rs.close();

But i am getting list size as '0' 
What am i doing wrong

Ashish
