How to show Oracle DB Tables on my JDeveloper Swing projects frame? - oracle

Question

I want to show my Oracle DB tables on my application. I create a new database connection DBConnection1. But I don't bind DBConnection1 in my class. How to do it?

Answer 1

OK. I solve my 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++;
Here is the my connector class.
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;
}
}
