I can't seem to get any of my own classes to successfully implement the
Serializable interface under Linux or Irix. I have no problem serializing
native objects like java.lang.String or java.lang.Integer. Also,
serializing my own classes worked fine using the Sun JDK for Windows95.
Is this a kn
You probably want to use a Vector.
import java.util.Vector;
Vector vec = new Vector();
Then, to add an element, use:
vec.addElement(someString);
to retrieve an element, you can use:
String myString = (String)(vec.elementAt(index));
(you've got to cast the returned object into a String)

I'm not positive this will sove your problem, but you might want to try
flushing that OutputStream after you write to it:
clientsocket_out.flush();

If you're using Netscape, you can use LiveConnect to talk to JavaScript
from a Java applet and vice-versa.
In your applet you'll need to do something like this:
import netscape.javascript.*;
import java.util.*;
public class MyApplet extends java.applet.Applet {
JSObject window;
Hashtable
While we're on the topic of Apache and Java, here's a question:
Using the Jserv module, you're supposed to be able to set init arguments
for individual servlets, and globally for all servlets. Here's what the
Jserv documentation says:
You can give that servlet init arguments by using a property
HttpServletRequest.getParameter("name1") should return "" in the case of a
URL like http://whatever.com/servlets?name1=&name2=someVal
Regardless, this is still problematic, since you probably want that value
to be null.
What I've done to get around this is provide my servlets with the
following
I hear you loud and clear. There's really no way that you could be
getting "null" from that method invocation (unless of course, your query
string looks like http://...?name1=null).
Printing the return value of getParameter("name1") will print "null" or
"", however.
Are you using the JServ modu
Looks like ad is never being constructed. Thus,
ad.addElement(a);
throws a NullPointerException.
