Unhandled exception occured during the execution of the web application.

Hai friends i had a simple page consisting of a textfield and a button. Whenever i enter any data in the textfield that data must be submited to the corresponding database table, but it is showing the following error.

and i will also publish my code here for button action handler if any corrections are to be made please correct it and help me in solving out.

Corresponding JSP Source code:

<ui:button action="#{Page1.button1_action}" binding="#{Page1.button1}" id="button1" style="left: 47px; top: 72px; position: absolute" text="ADD"/>

corresponding Java Code for button action:

public String button1_action() {

// TODO: Replace with your code

try {

table1DataProvider.refresh();

table1DataProvider.cursorFirst();

if ( table1DataProvider.canAppendRow() ) {

RowKey appendedRow = table1DataProvider.appendRow();

if ( appendedRow != null ) {

table1DataProvider.setValue("Table1.Name", appendedRow, item.getText());

// set values of other fields, if any

table1DataProvider.commitChanges();

}

} else {

error("Cannot append row");

}

} catch (Exception e) {

throw new FacesException(e);
