I'm learning Java Web and would like to know if they could help me in the following: I have a form that I enter data in the bank, and under it a table in which I make the listing of what was inserted in the bank, however what happens is the following, I am trying to insert a data in the bank by that field, table row to update asynchronously. Could anyone help? This code is only sending a message in response because I had tried other ways and as I messed up I decided to leave anyway for the time being. Index.jsp
