Return Data from Oracle using a web service in AXIS - please help

Question

Hi Forum,
I am very new to web services and Java tech. and recently I have been assigned to work with technology and I am struggling to learn it and need your help and assistance.
I am trying to return some data from a an oracle database but I have to do that using a web service and I am using AXIS. For example below is a simple program that returns two columns for the demo EMP table
import java.sql.*;
class emp {
public static void main(String args[])
throws ClassNotFoundException, SQLException {
Class.forName("oracle.jdbc.driver.OracleDriver");
// or you can use:
// DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","scott", "tiger");
Statement stmt = conn.createStatement( );
ResultSet rset = stmt.executeQuery("select * from emp");
while(rset.next( )) {
System.out.println(rset.getString(1));
System.out.println(rset.getString(2));
rset.close( );
stmt.close( );
conn.close( );
} but I do not know how to convert this into a web service.
Please help.
Thanks in advance.
Regards,
Ravi

The following code returns Document. I will be calling the below function to convert my Resultset to document. In my JWS file i simply call a method with parameters. can a web service method in .jws file return Document type. It shows error will doing so. Please help me.
public static Document toDocument(ResultSet rs) throws ParserConfigurationException, SQLException
          Document res_doc = null;
          DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
          DocumentBuilder builder = factory.newDocumentBuilder();
          Document doc = builder.newDocument();
          Element results = doc.createElement("Results");
          doc.appendChild(results);
          ResultSetMetaData rsmd = rs.getMetaData();
          int colCount = rsmd.getColumnCount();
          while (rs.next())
          Element row = doc.createElement("Row");
          results.appendChild(row);
          for (int i = 1; i <= colCount; i++)
          String columnName = rsmd.getColumnName(i);
          Object value = rs.getObject(i);
          Element node = doc.createElement(columnName);
          node.appendChild(doc.createTextNode(value.toString()));
          row.appendChild(node);
          return res_doc;
     }
