I am doing an assignment which it consists of an Applet, where the user has to insert several values and the program has to draw a quadratic graph.

In my applet I want to display the graph in the border layout center and one control panel to the east side and another control panel to the south side.

For now both the control panels are the same, until I manage to make my applet display them I am not willing to waste time...

Hi,

I'm building a small application to get to know Struts2 and JSP.

I have a JSP page that contains a Struts form which basically takes in a person's name, phone number and address but I have no clue how to send that information into the table I have already built in my local database.

Can anyone show me an example or get me started?

Thanks!

I need some help to improve my code.
My code is duplicating the output, and the output format is not what I want.

Here is the full Pseudo code.

Code:

int binary = 0;
int sum;

while(binary<256)
sum = 0;
for(go through all 8 digits)
    if the i-th digit is 0
        sum += i
    if the i-th digit is 1
        sum -= i
end for

if sum == 0

I have a split database used by up to 8 users with no problems. Front end Access 2007 backend Access 2003. Some of the users have had Java on their pcs upgraded to work with another aplication and now they are unable to use the Access DB. There is no Java connection involved.Versio n 1.6.0_18
Would bringing backend up to 2007 help or is it more complicated.
Any ideas appreciated.
