Hey!
If you mean something like this:
public class myClass extends HttpServlet
{
// Create a PrintWriter to write the response
java.io.PrintWriter out = new java.io.PrintWriter(resp.getOutputStream());
// Set the content type of the response
resp.setContentType("text/html");
// Print the HTML header
out.println("<html>");
out.println("<head>");
...
...
public void doGet(HttpServletRequest req,
HttpServletResponse resp)
throws ServletException, java.io.IOException
{
String myVariable = "This is the string";
...
...
myMethod(myVariable, out); //pass a reference of object
...
...
// Wrap up
out.println("</html>");
out.flush();
out.close();
}
myMethod(java.lang.String theVar, java.io.PrintWriter out) {
out.println(theVar);
}
}
I have found that this works for me.
I am confused by your statement, "I use this vector to hold the results of my database
query and pass the records to my applet.
The question I would ask is are you displaying Vector contents in the applet or are
you displaying in the HTML document?
If you are using an applet, why not just get a JDBC connection to the database, fill
up your Vector and have at it. Why are you using a servlet?
