Hi !
I am connecting to a database in an applet. After I come out of the applet,
I want to save the Connection object so that another applet can use it. I
tried to save the Connection object using Serializable interface but got the
"java.io.NotSerializableException: sun.jdbc.odbc.JdbcOdbcConnection"
exception at run time. So I assume Connection is not an Serializable object.
So I created an Serializable class with a connection object as one of the
member and tried to save this new Searizable class. But I again got the same
exception. So I assume that all the member of a serializable class has to be
Serializable.
Can u please tell me if my above conclusions are correct. If not can u tell
me what may be wrong. And if yes.... well can u advise me of any other
method to achieve my objective.
Thanks and Regards
Sameer
class temp implements Serializable
{
Connection con;
public void setCon(String login, String password)
{
try
{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
}
catch(java.lang.ClassNotFoundException e)
{
System.out.println("ClassNotFoundException : ");
System.out.println(e.getMessage());
return;
}
try
{
con =
DriverManager.getConnection("jdbc:odbc:test",login,password);
}
catch(SQLException ex)
{
System.out.println("SQLException : " + ex.getMessage());
}
}
public Connection getCon()
{
return con;
}
}
public class Description extends Applet implements Serializable
{
Connection con;
temp conTemp = new temp();
public void init()
{
conTemp.setCon("login","password");
con = conTemp.getCon();
try
{
FileOutputStream fOut = new FileOutputStream("samTest.out");
ObjectOutput out = new ObjectOutputStream(fOut);
out.writeObject(conTemp);
out.flush();
out.close();
}
catch(FileNotFoundException e)
{
System.out.println("File not found error. Error message : "
+ e.getMessage());
}
catch(IOException e)
{
System.out.println("I/O Exception. Error message : " +
e.getMessage());
}
}
