Hi, i create this simple java project:
CODE OF SIMPLE JAVA PROJECT:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

class test{

	public static void main(String[] args) throws SQLException {

	
//	public boolean getConnection() throws SQLException{
	
		String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
		
		String server = "localhost";
	    String database = "Greco";
	    String jdbcUrl = "jdbc:sqlserver://"+server+";database="+database+";integratedSecurity=true";
  
	    	try   
	        {     
	                Class.forName(driverName);               
	        }   
	        catch (ClassNotFoundException e1)  
	        {     
	            System.out.println("Class.forNameException; "+e1.getMessage());     
	        }     
	                 
	        Connection con = null;     
	              
	        try  
	        {     
	            // System.out.println("database connected");  
	            con = DriverManager.getConnection(jdbcUrl); 
	        //    System.out.println("database connected"); 
	        //    System.out.println("Connessione: "+con.toString()); 
	        }  
	        catch(SQLException e)  
	        {     
	        	 System.out.println("database NOT connected"); 
	            System.out.println(""+e.getMessage());     
	        }     
	      
	     Statement st = null;     
	     ResultSet rs = null;     
	               st = con.createStatement();     
	              // st.executeQuery("select * from dbo.Fermentazione"); 
	               st.executeQuery("SELECT Top 1 [idSerbatoio],[nomeVino],[dataInizioFermentazione],[dataFineFermentazione]"+
  "FROM [Greco].[dbo].[Fermentazione]"+
"where idSerbatoio = '1001'"+
"order by dataInizioFermentazione desc");
	               rs = st.getResultSet();     
	            
	             
	               while(rs.next())   	               {     
	            	   // JDBC columns starts at 1       
	            	   System.out.print(rs.getString(1)+" ");
	            	   System.out.print(rs.getString(2)+" ");
	            	   System.out.print(rs.getString(3)+" ");
	            	   System.out.print(rs.getString(4)+" ");
	            	  // System.out.print(rs.getString(5)+" ");
	            	//   System.out.print(rs.getString(6)+"\n");
	            	   
	     			}
	       
	             
	           rs.close();
	           st.close();
	           con.close();
	           
	}

}

Executing the main class, this code works fine. But I would create a Dynamic Web Project, so i create a Dynamic Web Project and i put this code in a method like this:
CODE OF DYNAMIC WEB PROJECT:

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;


public class ConnectionClass {
	
	public String getConnection() throws SQLException{
	Boolean connectionResult = false;
	String driverName = "com.microsoft.sqlserver.jdbc.SQLServerDriver";
	String server = "localhost";
    String database = "Greco";
    String jdbcUrl = "jdbc:sqlserver://"+server+";database="+database+";integratedSecurity=true";

    	try   
        {     
                Class.forName(driverName);               
        }   
        catch (ClassNotFoundException e1)  
        {     
            System.out.println("Class.forNameException; "+e1.getMessage());     
        }     
                 
        Connection con = null;     
              
        try  
        {      
            con = DriverManager.getConnection(jdbcUrl); 
            connectionResult=true;
        }  
        catch(SQLException e)  
        {     
        	 System.out.println("database NOT connected"); 
            System.out.println(""+e.getMessage());     
        }     
      
     Statement st = null;     
     ResultSet rs = null;     
               st = con.createStatement();     
              // st.executeQuery("select * from dbo.Fermentazione"); 
               st.executeQuery("SELECT Top 1 [idSerbatoio],[nomeVino],[dataInizioFermentazione],[dataFineFermentazione]"+
"FROM [Greco].[dbo].[Fermentazione]"+
"where idSerbatoio = '1001'"+
"order by dataInizioFermentazione desc");
               rs = st.getResultSet();     
            
             
               while(rs.next())   	               {     
            	   // JDBC columns starts at 1       
            	   System.out.print(rs.getString(1)+" ");
            	   System.out.print(rs.getString(2)+" ");
            	   System.out.print(rs.getString(3)+" ");
            	   System.out.print(rs.getString(4)+" ");
            	  // System.out.print(rs.getString(5)+" ");
            	//   System.out.print(rs.getString(6)+"\n");
            	   
     			}
       
             
           rs.close();
           st.close();
           con.close();
           if(connectionResult)  return "Connessione stabilita";
           else return "Connessione non avvenuta";
}
}

Now, how can I test this dynamic web project? How can I create a client?
Thanks
