Hi Experts,

Scenario:

1. when i click a drop down box from JSP form select -> it calls a java script method -> which in turn makes ajax post request to servlet using jquery.
2. I receive the strings from servlets and append the options into the select.

Issue:
1. When i first click on the dropdown select, its showing none. - what is happening is its making the ajax call, however because the drop down is getting closed immediately, I am not able to see the data until i click this second time.
2. Secondly, because I used onclick event to run this script, every time i click the drop down, it keeps appending the options cumilatively.

Code:

HTML:
<select id="companycode" name="companycode" onclick="getcompanycodes();"> <option value="">--Select--</option>

SCRIPT:
function getcompanycodes() { $.post("QueryServlet", { ccode: "all" }, function(data) { if (typeof data == "string") { var split_data = data.split(','); $.each(split_data,function(number){ $('#companycode').append('<option value=' + split_data[number] + '>' + split_data[number] + '</option>'); }); } }); }

Your prompt will greatly be appreciated.

Thanks
Viswa.

Amith,

I am in the page same page. May be my wordings are little amateur. Your explanation gives a lot of clarity though.

Thank You

Tim,

Thanks for your quick reply and it was a good piece of information.

I am able to see the session object in the other servlet. So the httpsession's scope is across webapp, not just servlet cool.

Thank you so much.

Hi I have 2 servlets, Authentication Servlet and Application Servlet. I am checking user credentials against active directory (LDAP). Upon successful login attempt, user is redirected to the right welcome page. In the welcome page, I have a form with a submit button. When the user submits the form, it will hit the Application Servlet's doPost(). My question is, how will i check if the user's session is active before serving the form request?

I only have the session object available in Authentication Servlet, but my application Servlet does not know about it. Do i need to maintain any persistance in my code apart from the HttpSession's API? Can someone help me?

Thanks
