when I got the user inputting. For example, user input the value "test's"/"test&s"/"test\s". How to insert the value into oracle DB by jdbc.
Thanks for you reply!

how to detect the servlet wheather it was initialized.

When I started the weblogic. I want to initialize all of servlet. How shoul I implement this function.
Thanks!

I think this problem is very monstrosity. I resarched all of material. I can't find any key.
I wanted superior can help me settle the problem. Our project will be end. I will very malformation if this problem can't be settled.
Thanks!!

It is class which implements the Serializable interface.

my applet interact with the webserver by HTTP protocol. I need to get a object from server.
But when I used the ObjectInputStream object readObject method. It throw a exception:
Server code:
ObjectOutputStream objout = new ObjectOutputStream(response.getOutputStream());
response.setContentType("application/octet-stream");

if (result.size() > 0)
{
for (int i = 0; i < result.size(); i++)
{
objout.reset();
objout.writeObject(result.get(i));
objout.flush();
}
}
else
{
Lesson lesson = new Lesson();
objout.writeObject(lesson);
objout.flush();
}
It is right.
Client code:
ObjectInputStream read = new ObjectInputStream(socket.getInputStream());

System.out.println("Get the outputing object2");

Vector result = new Vector();
Lesson lesson = null;
while ((lesson = (Lesson)read.readObject()) != null)
{
result.add(lesson);
}
writer.close();
socket.close ();
It meet problem:

I used applet as client. I transfer some parameters to servlet by HTTP. Servlet search some data from DB(List). how do I get the List data. (I want to get the List object).

I make a JSplitPane. place a jtree in left. place a JPanel in right. I had configed "splitPane.setOneTouchExpandable(true)". But I can't change the size of right and left by mouse.

thanks!!!
