IE Caching problem..Struts Application Working fine in Firefox
Hello All,
We have a struts application and the server is Tomcat 5.5. I have an
ArrayList (A) set in session and an Arraylist (B) which is a subset of A set
in request. The ArrayList B always has 10 elements and I use this to be
displayed in the jsp page using Logic:iterate tag. The first page displays
the arrayelements of List B from request, and when the user clicks next a
different action is called which selects a particular subset from A and puts
it in B and forwards to the same Jsp page to be displayed there. The next
page is working fine in Firefox and displays the new set of elements but in
IE 6.0 it displays the old set of elements, it doesnt get changed. I have
placed <% response.setHeader("Cache-Control","no-cache"); //HTTP 1.1
response.setHeader("Pragma","no-cache"); //HTTP 1.0
response.setDateHeader("Expires",
-2000); //prevents caching response.setHeader("Cache-Control","no-store");
//HTTP 1.1 %> on the top of the jsp and also <META HTTP-EQUIV="Pragma"
CONTENT="no-cache"> <META HTTP-EQUIV="Expires" CONTENT="-1"> <META
HTTP-EQUIV="Cache-Control" CONTENT="no-cache"> in the head. I have also
placed <controller nocache="true"></controller> in the
struts-config.xml........Even after doing all these its not working in IE
6.0. But everything is fine in Firefox. I have been trying to solve this
problem from 2 days.
Please HELP!!!
Thanx,
Struts Programmer.

I'm sorry to get your hopes up but the problem I had was related to IE
caching mime-types and must be different from yours. I thought it might
be related but that seems unlikely now since the change in IE settings
didn't have any effect.
Here's the link if you're curious:

help for file upload
Posted by Debendra Barik <on...@yahoo.com>.
Hello,
can anybody help me, i have a problem in uploading file into mysql database.
I am not getting the right way how to do it.
Here i am giving some details about my ActionForm, javaBean and database table
//CompanyForm(ActionForm) has a member variable and setter/getter
private FormFile logo;
Public void setLogo(FormFile logo){
this.logo=logo;
}
public getLogo(){
return logo;
}
//javaBean
Company.java
private byte logo[];
setter
public setLogo(byte[] logo){
this.logo=logo;
}
public getLogo(){
return logo
}
Database Table name is company has field like:
logo Blob;
//java class directly communicating with database
CompanyDB{
Company getCompany(); // get company details from database and return a company object
insertCompany(Company company) // insert company into database, taking a company object.
}
Now the matter is how do i store uploaded file into company bean logo filed and send it to the database by calling nsertCompany(Company company) method. And again how do i retrive it and store in the CompanyAction form logo field to show in the GUI.
Anybody can suggest me about if any better way have to do it.
Thanks,
Debendra.

Thanks Leticia.........I have tried to deceive the browser by appending a
parameter which has a random number this way
/GetOtherSet.do?rand='+parseInt(Math.random()*99999999);
BUT IT DOES'NT HELP..........Surprisingly when I print the elements on the
console using System.out.println in the jsp.......I get the new set of
elements every time which is rite. But while displaying it in the jsp page
IE displays the old items..........Why is it??

Re: IE Caching problem..Struts Application Working fine in Firefox
Posted by Letícia Álvares Barbalho <le...@gmail.com>.
I had a similiar problem with IE. Here goes how I solved it:
*<jsp:useBean* id="now" class="java.util.Date"* />
*
/MyApp/getPedido.do?id=*<fmt:formatNumber* value="*${*now.time*}*" */>*
The first line is obviously including the bean, while the second is
what comes in my link, calling the action.
As you see I created a auxiliar parameter to make IE think that
something new is coming.
That was the only way I found to solve this problem: deceiving the browser.
Yeah. I hate IE too.
Hope it's helpful.

Thanks for the reply Brady........I have cleared the cache and tried all the
options for "Check for newer versions of stored settings." ----"Every visit
to page" and "Automatically". Even then its not working. If its the Apache
setting problem then why is it working fine in Firefox. Could you please let
me know the setting change in Apache. I am really frustrated with this IE
caching problem. Someone out there please HELP!!!

Re: IE Caching problem..Struts Application Working fine in Firefox
Posted by br...@bitstream.net.
You might try changing the "Check for newer versions of stored settings."
As described in the following URL.
http://www.microsoft.com/windows/ie/using/howto/customizing/clearcache.mspx
It should either be "Every visit to page" if that's what you have now try
"Automatically".
If that's the problem there also may be a setting in Apache that fixes or
works around the issue. I had a similar problem with a servlet awhile
back and the a fix was to make the change in Internet Exploerer. However
the problem resolved itself in some unknown way while we were working on a
better solution.
