Comment afficher les tables Oracle DB sur mon cadre de projets JDeveloper Swing?

Question

Je souhaite afficher mes tables de base de données Oracle sur mon application. Je crée une nouvelle connexion de base de données DBConnection1. Mais je ne lie pas DBConnection1 dans ma classe. Comment faire?

Answer 1

OK. Je résous ma question.

  DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); 
      Connection connection = DriverManager.getConnection(connStr,"scott","tiger"); 

      Connector conn = new Connector(connStr); 
      Statement stmt = conn.getConnection().createStatement();      

      ResultSet rset = stmt.executeQuery(sql); 
      ResultSetMetaData metaData = rset.getMetaData(); 

      int rowCount = metaData.getColumnCount();     

      for(i=1;i<=rowCount;i++) 
       headers.add(metaData.getColumnLabel(i).toString()); 


      while(rset.next()){   
       Vector tmp = new Vector(); 
       for(i=1;i<=rowCount;i++) { 
        tmp.add(rset.getString(i));    
       } 
       lists.add(tmp); 
       index++;        

Voici la classe my connector.

package client; 

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


public class Connector 
{ 
    private String connection_string; 
    private Statement stmt; 
    private Connection connection; 

    public Connector(String conn) 
    { 
     //String connection_string = "jdbc:oracle:thin:@<host>:<port>:<db name>"; 
     try 
     { 
     connection_string = conn; 

     DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver()); 

     connection = DriverManager.getConnection(conn,"scott","tiger");     

     } catch(Exception f) 
     { 
     f.printStackTrace(); 
     } 

    } 

    public ResultSet execute(String sql) 
    { 
    try 
    { 
     stmt = connection.createStatement(); 
     return stmt.executeQuery(sql); 
    } catch (Exception f) 
    { 
     f.printStackTrace(); 
    }  
    return null; 
    } 


    public void setConnection_string(String connection_string) 
    { 
    this.connection_string = connection_string; 
    } 


    public String getConnection_string() 
    { 
    return connection_string; 
    } 


    public void setStmt(Statement stmt) 
    { 
    this.stmt = stmt; 
    } 


    public Statement getStmt() 
    { 
    return stmt; 
    } 


    public void setConnection(Connection connection) 
    { 
    this.connection = connection; 
    } 


    public Connection getConnection() 
    { 
    return connection; 
    } 
}
