Question

I have a web project in eclipse using glassfish. I have the following datasource entries in context.xml

<?xml version="1.0" encoding="UTF-8"?>
<Context>
    <Resource name="jdbc/TestDS" type="javax.sql.DataSource"
        url="jdbc:oracle:thin:@server:1521:db1"
        driverClassName="oracle.jdbc.OracleDriver" username="test" password="test" />
</Context>

When I run my application

DatabaseMetaData dmd = connection.getMetaData();
 String name = dmd.getDatabaseProductName();

Database product name is always Apache Derby

What could be the reason for this? I am trying to connect to Oracle Database however connection is made to Apache Derby.

How can I resolve this issue?

Thanks

Update 1

public static DatabaseConnection getInstance(String name)
            throws DatabaseException {

        DatabaseConnection instance;
        DataSource ds;
        try {
            InitialContext ctx = new InitialContext();
            ds = (DataSource) new InitialContext().lookup("java:comp/env/"
                    + name);


        } catch (NamingException e) {
            e.printStackTrace();
            throw new DatabaseException("###data source is invalid ###" + e);

        }
        instance = new MYDataSource(ds);

        return instance;
    }

I have resolved this issue.

I created a a JDBC Resource under GlassFish and pointed connection to my connection created under Date Source Explorer. It created a sun-resources.xml. I had to manually rename this to glassfish-resource.xml. By default there are no entry for password,so I had to manually add <property name="Passwrod" value="password" />. When I ran my web application I was getting this error

java.sql.SQLException: Error in allocating a connection. Cause: No PasswordCredential found

So to resolve this error I added a property in JDBC Connection Pool in glassfish admin server. Now I could connect to Oracle database.

Not sure why I have to do two steps manually.
