I made this code which simply fetches the data and each row has a Edit link Besides it...
When i click on Edit, the record appears perfectly, but when i make changes and click on save, it refreshes and shows null values in every Text Box. However, It makes changes to the Table.


This is the Code For EDIT page

OK.

make a commit of first transaction before you fetch with the second statement.

con.commit();

thank you sir but that wont Solve the problem. This problem is combination of Java and SQL.

Initially i thought, it was Servlet only problem, then it became purely SQL problem, and then a Combination.

The complete solution is here

Can you check the value of s during the refresh?

value of s remains same. When on Display List page, i click on edit and it attaches a parameter "value" which becomes the value of s. Then later on it stays in the servlet as hidden field and keeps passing no matter how many times i refresh it.
