Next() problem?
Hi to everybody,
I am new at Java and of course JSP but i am trying to use Next() method. Whenever i try to use that method in my web application, the page is posted back but always the first row of the data comes up. I can't jump to the second row in the database. But to let you know, i am using netbeans 5.5 to create my project, so i make it by netbeans' GUI so i don't write any code for it, just have Visual Web Pack and just double click to Next() method from palette.
Thanks for the helps.

well there is no particular code, ide just creates it and i just drag the table into the jtable from my database and i have a button which is suppose to get to the second row but it always stays in the first row when the page is posted back.. So is it normal or abnormal because as much as i know teh Next() is to get the 2nd. row. but it always gets the 1st. row like when the page is post back the cursor gets to the top again. Sorry for the code thing cuz there is no particular one i mean there is the code which tries to move the cursor
public String button1_action() {
try {
customerDataProvider.cursorNext();
} catch (Exception ex) {
throw new FacesException(ex);
}
return null;
}

Maybe you should learn to walk before you run, and ignore JSPs until you can write Java.

Autobuilder tools are for when you know what you are doing, but want to do it faster. Not for when you are just starting. Throw NBs in the bin, learn Java using a simple syntax highlighting text editor, and the command line.
