1) Please be sure to take the time to compose descriptive subjects for your posts. You will attract people who will can give you better and faster answers when your posts have good, descriptive subjects. For more information, please click this link ⇒ UseAMeaningfulSubjectLine.
Using a title such as "JAVA-JSP" isn't going to attract the attention of those who can best help you. Especially where you've already used this subject for another post.
You can change your subject line by clicking the button on your post.
2) Please be sure to use code tags when posting code to the forums. Unformatted or unindented code is extremely hard to read and many people that might be able to help you will just move along to posts that are easier to read. Please click this link ⇒ UseCodeTags ⇐ for more information.
Properly indented and formatted code greatly increases the probability that your question will get quicker, better answers.
I would love you help you, but I can't find where your problem is. Is it in editing/deleting in mysql, or is it getting your buttons to do it, and so on?
You would attract more helpful persons if you stated where it is you're having a problem, and what your thoughts about it are.
Step 1: No java code in JSPs! Factor the Java code out into Java classes.

The reason why your text boxes are empty, is that you only declare the strings before you set them as value of the text boxes:
You also have to assign them values before you use them in the form. One way you can fix this, is to move the code for your form under the JSP code,
so that you are certain that the strings have values, when you 'use' them.
An example for you:
This wouldn't work:
This would just give us an empty text box.
While this would do what you want:
And we would get a text box with the value: "A string" (without the quotes). (I have excluded some of the required syntax to make the examples work,
to make it easier to follow)
Hope this cleared something up for you. If not, feel free to ask again.
Good luck with your project!
