Hello,

Need to clean cache of client browser,using jsp as front end.
though have already written the below code

 <% response.setHeader("Cache-Control","no-cache"); //HTTP 1.1 
 response.setHeader("Pragma","no-cache"); //HTTP 1.0 
 response.setDateHeader ("Expires", 0); //prevents caching at the proxy server  
%>

Open in new window


But almost 90% of the times we need to ask the client to manually clean the cache,after that only the new changes are reflected in the client browser,say we have created new button on screen, which is not visible but when the user cleans the browser cache manually the button seems to work display.

2. 1 Script once in a day.
3. 1 script on particular times like 10.45, 11.15....

please let me know if you need any more details.

Hi - I have the below line in my jsp and i am getting error saying
unterminated &lt;

 
var myString = "<img src='images/clear.gif' width='8' height='5'><mytags:dropdown  fieldID=" +"'"+ extDataID+ "'"+" category= " +  '<%=com.test.myString.GET_VALUE_TEST%>' + " selectedOption='' style='InputFields'/>";
			

Open in new window


so what is wrong in the above syntax is javascript not accepting <%= %>

I can pinpoint the error to this line because when i replace the above line with the below line no issues
var myString = "<img src='images/clear.gif' width='8' height='5'><input type='text' name=" +"'"+ test+ "'"+" maxlength = '40' size='64' value='' class = 'InputFields'>";

Note that, all by itself, that class definition compiles w/o errors.

In my program I do the following:
PurchaseData rd = new PurchaseData();
//and I've tried:
PurchaseData rd = new PurchaseData(null,null,null,null,null,null,null,null,null,null,null);

when I try to run, I get:

I'm very new to unifi, html and css. Please be gentle with me.
I have the current windows version of the Ubiquiti Unifi controller.
I am able to modify voucher.html and voucher.css to produce custom hotspot vouchers.
I want to print, on the voucher, the date and month the voucher was created.
I have added the following line to voucher.html:
<div class="create_time">Create Time: <unifi var="create_time" /></div>
 
The voucher prints "Create Time:" but does not print the date/time.
Any assistance is much appreciated.

I was reading about Resource Bundles

as below
internationalization feature of the JDK provides a mechanism for separating user interface (UI) elements and other locale-sensitive data from the application logic in a program.
I can relate with local sensitive data separation but not the UI elements like buttons etc why we need to separate?

I have a legacy system developed 10 years ago.

 A jsp page---SalesEditBillingAddress.jsp

<jsp:include page="/WEB-INF/forms/include/edit_billing_address.jsp" > 
<jsp:param name="dept" value="sales"/>
</jsp:include>    

Open in new window


second jsp page---marketingEditBillingAddress.jsp

<jsp:include page="/WEB-INF/forms/include/edit_billing_address.jsp" > 
<jsp:param name="dept" value="marketing"/>
</jsp:include>    

Open in new window


The reason to pass the parameter is because the generic page----edit_billing_address.jsp has different form action need to be submitted based on different parameters.

  <html:form action="/actions/${param.dept}/editBillingAddress">
<html:text name="customerBillingAddressBean" property="address1"  maxlength="60"> </html:text> 
.............
<html:text name="customerBillingAddressBean" property="contact" maxlength="60"></html:text>
<html:text name="customerBillingAddressBean" property="email" maxlength="80"></html:text>

<button type = "submit" class ="btn btn-primary">Submit</button>		   
</html:form>        

Open in new window



however, tomcat 8.0 with java 1.8 complain about this line of code:
<html:form action="/actions/${param.dept}/editBillingAddress">

Open in new window


javax.servlet.ServletException: javax.servlet.jsp.JspException: Cannot retrieve mapping for action /actions/${param.dept}/editBillingAddress

The example on this page:

http://beginnersbook.com/2013/12/jsp-include-with-parameter-example/

shows that my code is nothing wrong about it.

my question is: how to make the parameter work in the action URL?

I also tried the following code:

			 
			 <c:set var="myVar" value="${param.dept}" />

			 <c:if test = "${myVar eq 'sales'}">
			   <html:form action="/actions/sales/editBillingAddress">  
			 </c:if>
		    
		        <c:if test = "${myVar eq 'marketing'}">
			   <html:form action="/actions/marketing/editBillingAddress">
		         </c:if>

                ............. many input fields ...............

                        <button type = "submit" class ="btn btn-primary">Submit</button>		           
	                </html:form>        
	  

Open in new window


but it doesn't work because the eclipse compiler give error message due to only one closed form tag could be found.
