I have a method that inserts data into my Oracle 9i database with no
problems or Database closing issues:

CODE
public class MainClass
{

public PreparedStatement preparer;
public Connection connection;

public MainClass()
{
    connection = new DbConnectionClass().getConnection();
}

public int inserter(Beann abc)
{
  int dat = 0;
  try
 {
     preparer = connection.prepareStatement("insert into abTable
(one,two) values (?,?)");
     preparer.setString(1, abc.getOne());
     preparer.setString(2, abc.getTwo());
     preparer.executeUpdate();
  }
  catch(Exception e)
 {
     e.printStackTrace();
 }
 return dat;
}

public int matcher(Beann abc)
{
    try
    {
   inserter(abc);
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
    finally
    {
       //close the ResultSet ....
       //close the Statement  ....
       //close the Connection  ....
    }
}

Now when I put the method (inserter) in another class called
OtherClass, it does insert the data but now I have database closing
issues:

CODE
public class OtherClass
{
...
public int inserter(Beann abc)
{
  int dat = 0;
  try
 {
     preparer = connection.prepareStatement("insert into abTable
(one,two) values (?,?)");
     preparer.setString(1, abc.getOne());
     preparer.setString(2, abc.getTwo());
     preparer.executeUpdate();
  }
  catch(Exception e)
 {
     e.printStackTrace();
 }
 return dat;
}
....

CODE
public class MainClass
{

public PreparedStatement preparer;
public Connection connection;

public MainClass()
{
    connection = new DbConnectionClass().getConnection();
}

public int matcher(Beann abc)
{
    try
    {
        new OtherClass().insert(abc);
    }
    catch(Exception e)
    {
        e.printStackTrace();
    }
    finally
    {
       //close the ResultSet ....
       //close the Statement  ....
       //close the Connection  ....
    }

In Oracle SQL Plus database resource check I see JDBC Thin Client is
opened and not closed after each insert with the above attempt.
This didnt happen when I had the method in the same class.

Please advise.
