i am developing a application in struts 1.3 in struts i have a requirement that when click on the submit button of the form then the button gets disabled so as the user cannot submit the form multiple times for that i am using this code

<input value="Save" class="btnbg" type="submit" name="method"
onclick="this.disabled=true;" />

in this code on click of the button it gets disabled now it is getting disabled but i am facing a peculiar problem that action in the action class is not executing i am using DispatchAction class for execution of my action it code works fine if i remove onclick="this.disabled=true; the action gets executed but i am getting exception

}

return req;
}

//Make the XMLHttpRequest Object
var http = createRequestObject();

function sendRequest(method, url)

p_statement = connection.prepareStatement(sqlst);
p_statement.setString(1, country);

result = p_statement.executeQuery();
while(result.next())
{
buffer=buffer+"<option value=\""+result.getString("ID")+"\">"+result.getString("name")+"</option>";
