javascript to detect chrome url from iframe

I am having an application in an iframe and I am calling this from a different domain. For example, my browser url is a.com and my iframe url is b.com (different domain). I am loading this iframe (b.com) in a.com thus making their domains different.
I tried with the below function in js, this works in IE and Mozilla, however, with Google chrome, my js is not able to reach the browser url.
Would appreciate if anyone can give me some direction on this

sas.jar and wssec.jar missing from was 6.1 install

I am getting the below error after deploying few projects in was 6.1

After some research, I found out that was 6.1 does not come with sas.jar and wssec.jar files and due to the absence of which I am getting the above error.
I tried putting the sas.jar file from was 5.1's lib directory, but the server does not seem to start in that case.
Does WAS 6.1 come with these jar files? If not, where can I find its compatible jar files through which I would be able to resolve the error?
If there is an alternative to this, please let me know.
Any help is greatly appreciated.
Thanks.

Portals and Portlets

split a swf from one giant swf

I need to create a portlet in which I will be including one of the swf files from one large swf file. We have a website which runs multiple swf applications in one large swf. Is there anyway I could split one of those swf files and use it into my portlet. I need some guidance on this.
Any help is appreciated. Thanks.

Refresh everything in jsp and start over

Its a long code. This is how it works:
I click on a state, and the page displays its related cities.
I click on a city and it displays their zip codes.
I click on a zip code and it displays the temperature for all days.
I just made the connection and linked these tables with the help of SQL. I am not retreiving actual temperature.
In the end, I have a Start Over button. Upon clicking it, the page should redirect me to enter the state again (from beginning)

Here is my state.jsp code

I know its a very long code. If I don't get a reply on this, its fine because nobody wants to waste their time reading a long code. If you do, I would really appreciate your help.

Refresh everything in jsp and start over

Thanks for the reply Bear.
I tried reloading the window through javascript like the one below:

I am actually using Websphere Portal on JSR 168 API. After clicking on the button above, I get the error from the server console as:

"WARNING: Cannot set header. Response already committed."

I tried to invalidate the session and redirect the page back to the jsp (now assuming all the session attributes were gone). But upon running and clicking on that button, the browser displays "Page cannot be found". I have set up a button at the end of my jsp saying "Start Over" so that upon clicking on that button, I should get the page as I first loaded from the server. I tried removing attributes but that doesn't seems to be the solution. I am new to programming so please bear with me if this looks stupid to you. Any reply is appreciated. Thank you.

Refresh everything in jsp and start over

I am writing a jsp code where it displays cities upon selecting a state, which is through JDBC. I have placed a start over button in the end so that I could start the page again from the beginning. Is there anyway we could do this? Please let me know how i would approach. I tried removing attributes but that doesn't seem to be the solution. Any solution is appreciated. Thanks.

Retaining selected values in a portlet

I have few states listed in a drop down menu in a portlet. After clicking on a state, the portlet processes the action method and displays their cities. I have linked the cities with states through SQL. However, when the city is loaded, I need the state value to remain selected. Here is my code

<form action="<portlet:actionURL/>">
<tr>
<td><b>Select the state:</b></td>
<td><select name="state" size=5>
<option value="ny" selected>NY</option>
<option value="va">VA</option>
<option value="oh">OH</option>
<option value="mi">MI</option>
<option value="il">IL</option>
<option value="ca">CA</option>
</select></td>
</tr>
<tr></tr>
<tr>
<td><input type="submit" name="submitState" value="Submit" /></td>
</tr>
</form>
</table>
<%//======================RETREIVING CITIES INFO FROM STATE ENTERED=============================================================%>
<%
if (renderRequest.getPortletSession().getAttribute("dataList") != null) {
%>
<br><br>Available cities for <b><%=renderRequest.getPortletSession().getAttribute("searchStringState") %></b> are:<br><br>
<table border="1" width="200">
<%
Iterator itr;
List data = (List)renderRequest.getPortletSession().getAttribute("dataList");
for (itr = data.iterator(); itr.hasNext();) {
%>
<form action="<portlet:actionURL/>">
<% String temp = itr.next().toString(); %>
<tr>
<td width="150"><input type="radio" name="city" value="<%=temp%>" checked><%=temp %></td>
</tr>
<% } %>
</table>
<br><input type="submit" value="Next" name="submitCity" size="200">
</form>
<%
}
%>

code from processAction method
----------------------------------------

I need to know how would I keep the state as selected after the portlet had loaded cities. I know it had got to do something with boolean flags but I really don't know how to approach the problem. Also, after iterating through cities, I need the first value of the city to be selected. Further, after clicking on a city and submitting, both city and state value should remain selected with previously selected values. Thanks in advance.

Retrieve a column value from ArrayList

I am trying to retrieve a particular column name from Array List. I have the table in SQL as below:

+--------+----------+--------+---------------------------+
| day_id | day_name | temperature_in_fahrenheit |
+--------+----------+--------+---------------------------+
| 1 | Mon | 25 |
| 2 | Tue | 35 |
| 3 | Wed | 45 |
| 4 | Thu | 55 |
| 5 | Fri | 65 |
+--------+----------+--------+---------------------------+

I have made a jdbc connection and added the values to the ArrayList. I have to retrieve only temperature values from above so that I could calculate the temperature values in centigrades and store them in a session. However, I dont know how to approach. Please let me know if you can help me. Thank you.

Retain selected content in a JSP

I have 2 jsp files: login.jsp and process.jsp....In login.jsp, I placed combo boxes and radio buttons. On selecting the values from the combo box and radio button and further submitting, the jsp displays process.jsp where it should retain the selected content. Here are both of my jsp files:

login.jsp
-----------

process.jsp
-------------

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<script type="text/javascript">
function getSelected()
{
var combo = <%= request.getParameter("state") %>;
var radio = <%= request.getParameter("gender")%>;
document.process.state.value = combo;
document.process.gender.value= radio;
}
</script>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body onload=getSelected();>
<form name="process">
<br> State: <SELECT NAME="state" SIZE=0>
<OPTION VALUE="0"> Maryland
<OPTION VALUE="1"> Virginia
<OPTION VALUE="2"> Michigan
<OPTION VALUE="3"> Ohio
</SELECT>
<br> Zipcode: <%= request.getParameter("zipCode") %>
<br>
<table border="0">
<tr>
<td>Gender:</td>
</tr>
<tr>
<td><input type="radio" name="gender" value="male">Male</td>
<td><input type="radio" name="gender" value="female">Female</td>
</tr>
</table>
The selected gender was: <%=request.getParameter("gender") %>
</form>
</body>
</html>

The radio button is not selected in the next page. However, I could retrieve the name through request.getParameter method. I think is something wrong in my javascript. Please let me know where I am going wrong. Thank you.

Retain selected content in a drop down menu

Hello all. I am writing a portlet application. I have a drop down menu of states. After clicking on an item, the portlet will process the info and display the next portlet beneath it.
However, I need the content of that drop down menu selected in my next page.

Is there anyway we could retreive the selected content of a drop down menu in a jsp after clicking the submit button.
Thanks in advance.
