Connecting JdbcRowSet with a Connection URL

This section describes how to connect a JdbcRowSet object to a database server with a connection URL.

If a JdbcRowSet object is created without a connection to the database server, you can provide a connection URL string by calling the setUrl() method. A connection object will be created later by the JdbcRowSet object with DriverManager when you call the execute() method. Here is a sample sequence of method calls:

// Creating a JdbcRowSet object without connection
  JdbcRowSet jrs = new JdbcRowSetImpl();

// Provide a connection URL for future use

// Provide a SQL statement for future use

// Create a connnection using DriverManager
// Execute the SQL statement

Note that the name of method setUrl() is very confusing with another method setURL(), which sets a URL value to a parameter.

Note also that the connection URL and user information can also be provided through another constructor:

  JdbcRowSet jrs = new JdbcRowSetImpl("connection_url",
    "user", "password");

To test connection method, I wrote the following tutorial program:

 * Copyright (c) All Rights Reserved.
import java.sql.*;
import javax.sql.rowset.RowSetProvider;
import javax.sql.rowset.JdbcRowSet;
public class OracleRowSetConnectionUrl {
  public static void main(String [] args) {
    try {

// Not needed anymore with JDK 1.8
//      Class.forName("oracle.jdbc.OracleDriver") ;

// RowSetFactory should be used now
//      JdbcRowSet jrs
//        = new com.sun.rowset.JdbcRowSetImpl();
      JdbcRowSet jrs
        = RowSetProvider.newFactory().createJdbcRowSet();

// Set the connection URL for the DriverManager

// Set a SQL statement
      jrs.setCommand("SELECT 'Hello world!' FROM DUAL");

// Connect and run the statement

// Get the result;
      System.out.println("Result: "+jrs.getString(1));

// Close resource
    } catch (Exception e) {

Make sure the Oracle server is running on the local machine, then run this program. The result with JDK 1.8, Oracle 11.2 and ojdbc6.jar confirms that the connection is working.

herong> java -cp .;ojdbc11.jar OracleRowSetConnectionUrl

Result: Hello world!

But if you are JDK 1.6, Oracle 11.2 and ojdbc14.jar and use "new com.sun.rowset.JdbcRowSetImpl()" explicitly, you will get a compilation warning:

herong> Progra~1\java\jdk1.6.0_2\bin\javac \
   -cp .;\local\lib\ojdbc14.jar \
warning: com.sun.rowset.JdbcRowSetImpl is Sun proprietary API
and may be removed in a future release
        = new com.sun.rowset.JdbcRowSetImpl();
1 warning

herong> Progra~1\java\jdk1.6.0_2\bin\java \
   -cp .;14.jar OracleRowSetConnectionUrl

Result: Hello world!

Also notice that class com.sun.rowset.JdbcRowSetImpl seems to be included in JDK 1.6 package, because I executed the program successfully without including rowset.jar file in the classpath.
