Caching problem in jsps

I am facing a problem with the caching of the jsp .I am using struts in my application and I have 5 tabs at the top of my page .When I click a tab I will change the image source by using a variable from the attribute .but the problem is often when I run my application on another client browser and I click the tab �.the variable is set properly but the image in my jsp is not changing ��..
The piece of code in my jsp to change the image of the selected tab looks like
<td>
<logic:equal name="TAB" value="HOME%">
<% Sytem.out.println(�Tab not highlighted�); %>
<img border="0" src='<bean:message key="path.images"/>/top_f_btn_home_a.gif' width="65" height="32">
</logic:equal>
<logic:notEqual name="TAB" value="HOME">
<% Sytem.out.println(�Tab highlighted�); %>
<img border="0" src='<bean:message key="path.images"/>/top_f_btn_home.gif' width="65" height="32">
</logic:notEqual>
</td>
on clicking its enetering and shoing that tab is highlighted but the image is not getting changed .even I used
<META HTTP-EQUIV="cache-control" CONTENT="no-store">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="0">
to remove the cache but its not working ��..but the strange thing is that it always works fine on the system where the application is running but wont work properly on another client
Any help in this would be thankful
Regards

I'm not sure, but if I remember that expires should be set to -1 to indicate no caching

I am facing a caching problem in the Web-Application that I've developed us

Dear Friends,
I am facing a caching problem in the Web-Application that I've developed using Java/JSP/Servlet.
Problem Description: In this application when a hyperlink is clicked it is supposed to go the Handling Servlet and then servlet will fetch the data (using DAO layer) and will store in the session. After this the servlet will forward the request to the view JSP to present the data. The JSP access the object stored in the session and displays the data.
However, when the link is clicked second time then the request is not received by our servlet and the cached(prev data) page is shown. If we refresh the page then request come to the servlet and we get correct data. But as you will also agree that we don't want the users to refresh the page again and again to get the updated data.
We've included these lines in JSPs also but it does no good:
<%
response.setHeader("Expires", "0");
response.setHeader("Cache-Control" ,"no-cache, must-revalidate");
response.setHeader("Pragma", "no-cache");
response.setHeader("Cache-Control","no-store");
%>
Request you to please give a solution for the same.
Thanks & Regards,
Mohan

However, when the link is clicked second time then the request is not received by our servlet Impossible mate.. can you show your code. You sure there are no javascript errors ?
Why dont you just remove your object from the session after displaying the data from it and see if your page "automatically" hits the servlet when the link is clicked.
cheers..

Possible caching problem

I have a Pag1.jsp with 2 buttons, a dropdown with a button, as well as a datatable with an action link. Everthing works fine; the buttons, action links and dropdown. The problem arises with the actionLink; on the remote jsp pages the user can hit a button which takes him back to page 1.jsp. HOWEVER, IF HE USES THE BROWSER'S BACK ARROW HE GOES BACK TO PAGE1.JSP, BUT NOW THE 2 BUTTONs NO LONGER DIRECT PROPERLY, BUT SEND HIM TO THE LAST PAGE THE ACTIONLINK DIRECTED HIM TO. This problem is only caused by the browser back arrow and is removed by going to page1.jsp and hitting the refresh button...Is this a caching problem and what can I do about? Thanks for taking the time to read this.

Hi ,
I tried reproducing your problem with information provided by you , but was not able to reproduce. I was successful in bringing up the correct JSP pages on the click of buttons. The browsers back button takes me to the previous visited page and the button ,Action Links redirect me to the right JSP pages.

Creator Team.

Cache Problem in iPlanet (Solaris)

We are using iPlanet on solaris. we are having cache problem. Everytime we make any change in out JSP files we have to stop the server and then we clear the cache from ClassCache folder. Then we restart the server. Please let me know, how can I avoid restarting the server. Thanks

Sanjay,
You do not say which version you are using but I
believe some people had problems with 4.1 that went
away when they upgraded to 4.1.3.
The JSP source file should be compared with the
version in the cache at run time, so a newer version
should be picked up automatically. However, a JSP that
you only 'include' in an outer JSP will not be updated
because only the including JSP is checked for update.
If this is the problem you have, you should be
able to force a run time check for the inner JSP by
using "jsp:include page=<name>.jsp" in the including
(outer) JSP.
I hope this helps.

Caching problem w/ primary-foreign key mapping

I have seen this a couple of times now. It is not consistent enough to
create a simple reproducible test case, so I will have to describe it to you
with an example and hope you can track it down. It only occurs when caching
is enabled.
Here are the classes:
class C1 { int id; C2 c2; }
class C2 { int id; C1 c1; }
Each class uses application identity using static nested Id classes: C1.Id
and C2.Id. What is unusual is that the same value is used for both
instances:
int id = nextId();
C1 c1 = new C1(id);
C2 c2 = new C2(id);
c1.c2 = c2;
c2.c1 = c1;
This all works fine using optimistic transactions with caching disabled.
Although the integer values are the same, the oids are unique because each
class defines its own unique oid class.
Here is the schema and mapping (this works with caching disabled but fails
with caching enabled):
table t1: column id integer, column revision integer, primary key (id)
table t2: column id integer, column revision integer, primary key (id)
<jdo>
<package name="test">
<class name="C1" objectid-class="C1$Id">

<extension vendor-name="kodo" key="column.id" value="id"/>
</extension>
</field>
</class>
</package>
</jdo>
Because the ids are known to be the same, the primary key values are also
used as foreign key values. Accessing C2.c1 is always non-null when caching
is disabled. With caching is enabled C2.c1 is usually non-null but sometimes
null. When it is null we get warnings about dangling references to deleted
instances with id values of 0 and other similar warnings.
The workaround is to add a redundant column with the same value. For some
reason this works around the caching problem (this is unnecessary with
caching disabled):
table t1: column id integer, column id2 integer, column revision integer,
primary key (id), unique index (id2)
table t2: column id integer, column revision integer, primary key (id)

Needless to say, the extra column adds a lot of overhead, including the
addition of a second unique index, for no value other than working around
the caching defect.

Tom-
The first thing that I think of whenever I see a problem like this is
that the equals() and hashCode() methods of your application identity
classes are not correct. Can you check them to ensure that they are
written in accordance to the guidelines at:
http://docs.solarmetric.com/manual.html#jdo_overview_pc_identity_application
If that doesn't help address the problem, can you post the code for your
application identity classes so we can double-check, and we will try to
determine what might be causing the problem.

Bridge update does not fix caching problems.

Dear Adobe,
The 5.0.1.23 update for Bridge CS6 does NOT fix the problem of constantly re-caching layered TIF files.
I originaly reported the problem here on May 16, 2012.
http://forums.adobe.com/thread/1007560
At that time I also submitted a bug report via photoshop.com, and received an e-mail response from Adobe support confirming the problem had been replicated in their lab and promising a fix in the next update.
I've since tracked several other reports of this bug and related cache problems.
I assume that, at best, we will have to wait another 6 months or more for the next update. How can I assure this bug will be addressed?

Thank you for this bit of information. Maybe it means I can stop the deactivations/uninstall/reinstall/reactivate cycle to try yet another solution. And hopefully, this will stop the re-caching problem with other than tif files.

Problem in jsp with container(JEUS)

Hi I am a developer in Korea
Nowadays I have a problem in jsp pages which have contained some pakage directive in a library path
so my problem is changing some of the classes in the package during service time.
Error result is
-Root Exception stack trace :
-jeus.servlet.jsp.compiler.JspCompileException: fail to compile : source = C:\TmaxSoft\JEUS6.0\webhome\epims_container1\_generated_\j2ee-modules\harweb\jeus_jspwork\_custermg\_html\_mypage\_600_MyReqJob_5fjsp.java, -error msg = C:\TmaxSoft\JEUS6.0\webhome\epims_container1\_generated_\j2ee-modules\harweb\jeus_jspwork\_custermg\_html\_mypage\_600_MyReqJob_5fjsp.java:76: cannot access custermg.MyPageQuery
bad class file: C:\epims\harweb\WEB-INF\classes\custermg\MyPageQuery.class
-class file has wrong version 8241.8224, should be 49.0
-Please remove or make sure it appears in the correct subdirectory of the classpath.
- MyPageQuery myquery = null;
I don't know why this could be happed in random period of time It happens nearly each 10 hours . after this failure, the same error happen in other classes.
Before ten hours?.... No problem with the jsp pages
The number 8241.8224 tells me that it is not generated by java compiler but I don't have any clue but the above error
my run time environment is
- HP Server, Windows Server 2003, 64bit
- Jeus, jdk1.5.0_15
so any help from you will be appreciated...
thanks

Mr. Ahmed,
Excuse-me by my bad english.
I experienced the same problem when surrounded my scripts with comment caracters:

If this is your case, simply uncomment it and the script will work fine.

Caching problem in Chrome and Firefox

Hey folks,
I ran into a weird problem. I created a video player based on the Strobe Media Playback. I added a couple of plugins. This player is used to watch progressive download FLV files.
I ran into the following issue. I watch part of a video. I select another one. Then I select the previous one again. Only the cached portion of the first video is shown. The entire video will not be downloaded again from the server, but only the portion already cached on the client.
This problem is really bad in Chrome. When I restart FF, I can watch the entire video. Not in Chrome. The only way to solve this in Chrome is to clear the cache.
Any ideas?
The website is live, so you can test this yourselve. http://www.submergeproductions.com/videos.aspx
All help very welcome, because this is a major issue.
Follow up. I made a quick fix. I added a random number to the FLV url to force a redownload from the server, but this quite a dirty fix. I would rather have a restart/continuation of the download if the file was only partially downloaded.
Thanks,
Peter

Hi Silviu,
the reason why it works now is because I uploaded a modified version. I append "?<random number> to the URL. That prevents caching problems because the browser hasn't got the version cached. But I still report it as a bug.

Caching problem of servlet

Hi guys
We are facing this problem of caching within our project. The project aims to generate a html code to pick up some rich media ads details at random and displaying on the html file where the generated code is expected to be pasted. We developed two servlets, one which extracts the ads from the database randomly and then depanding on the ad type it calls the other servlet as src of an iframe, which in turn puts all code for displaying the rich media ads. The script which we are generating for the user to paste onto their pages is:
<script LANGUAGE="JAVASCRIPT" src="http://192.168.1.6:8080/advert_java/servlet/GetAdServlet?region=1&zone=1&type=nossi&cachevar=yes">
</script>First servlet (GetAdServlet) returns the javascript statements and thus is called using this generated code. Now cotents of the iframe are supplied by the second servlet ie richMediaServlet. This servlet is called like
iframeURL = fullHttpDir+"/servlet/RichMediaServlet?";
iframeURL += "bannerCode="+ RNBanner (BannerCode to be called);
out.println("document.write(\"<iframe src='" + iframeURL + "' height=" + hheight +" width="+ wwidth + " SCROLLING=no FRAMEBORDER=0 MARGINWIDTH=2 MARGINHEIGHT=2 onfocus='window.focus(); return iframeFocus()'>\");");
out.println("document.write(\"</iframe>\");");This richmediaServlet returns HTML into <iframe>. when richmediaservlet is called, a parameter 'bannerCode' is passed. then richmediaServlet fatches the banner from the database and displays the banner into the <iframe>.
Now the problem comes when we run the html file containing the script tag mentioned above, and refresh our page, ideally it should pick the ads randomly and pass it on to RichMediaServlet.
I also try debugging both servlets. I called the getadservlet from javascript mentioned above and put debugging info in both the servlets, now for every refresh we do on the html side, we are getting a different random bannercode in adservlet but in richmedia when we print the bannercode received in querystring it is taking an older value which was displayed some time back and keeps on doing this for quiet a long time, making it look like some caching problem of RichMediaServlet.
Instead when we tried to put the same html <script> code into another servlet's doGet, everything seems to be working fine.
i have also used the following code to prevent the caching on both the setvlets
long currentTime = System.currentTimeMillis();
response.setHeader("Cache-Control", "no-cache, must-revalidate");
response.setHeader("Pragma", "no-cache");
response.setDateHeader("Last-modified", currentTime);
response.setHeader("Expires", "Sat, 6 May 1995 12:00:00 GMT"); and following in the iframe's head tag before the iframe tag in the getAdServlet.
out.println("document.write('<head>');");
out.println("document.write('<meta http-equiv=\"Cache-Control\" content=\"no-cache,must-revalidate\">');");
out.println("document.write('<meta http-equiv=\"Pragma\" content=\"no-cache\">');");
out.println("document.write('<meta http-equiv=\"Last-modified\" content=\""+ currentTime + "\">');");
out.println("document.write('<meta http-equiv=\"expires\" content=\"Sat, 6 May 1995 12:00:00 GMT\">');");
out.println("document.write('</head>');");I request you all geeks to try and help me to your best. The project is at its final stages and in high urgency now.

i think the caching is being in the browser, with the iframe.
You should try passing a random param to the servlet in the iframe URL, something like:
var a = Math.random() * 10000000; //for example
out.println("document.write(\"<iframe src='" + iframeURL +"&rand="+a+"' height=" + hheight +" width="+ wwidth + " SCROLLING=no FRAMEBORDER=0 MARGINWIDTH=2 MARGINHEIGHT=2 onfocus='window.focus(); return iframeFocus()'>\");");
out.println("document.write(\"</iframe>\");");
...It should force the browser to ask for the servlet again
hope this helps...

Caching problem with Internet Explorer

Hi,
users of an ApEx application I'm working on are reporting that when they're deleting an uploaded file from one of the pages in the application (using Internet Explorer), the link to the file remains. This is however not an issue in FireFox, and after some research I found out that this is a caching problem in IE. It can be avoided by making IE check for newer versions of stored pages every time a page is visited, but it is clearly not an option to ask all our users to do this. I also learned that it can be fixed by randomizing the file URL every time the page is loaded, but I don't know how to randomize a URL, nor how to make it still point to the uploaded file.. Any help would be appreciated!
Thanks,
-Kjetil

Kjetil,
This problem is also there if you use Flash Charts with a drilldown. See this posting:
http://www.deneskubicek.blogspot.com/
It will also link you to a corresponding thread and to an example in my demo application.
The idea with a random number changing you link is the same I used in extending my
xml chart package.

Problem using jsp:include from inside a custom tag

Hi, All !
          I have a problem using <jsp:include> from inside a custom tag. Exception is:
          "java.lang.ClassCastException: weblogic.servlet.jsp.BodyContentImpl"
          Apparently, weblogic tries to cast BodyContentImpl to JspWriterImpl and
          could not do this. Is it a bug, since in the 1.1 spec is said: "The
          BodyContent is a subclass of JspWriter that can be used to process body
          evaluations so they can retrieved later on."
          My code is:
          <wfmklist:items>
          <jsp:include page="item.jsp" flush="true"/>
          </wfmklist:items>


This is an area of contention with WL. It is not so tolerant with regards to
          the spec. I spent several days recently trying to convince it to accept the
          specification in regards to bodies and includes and it appears to have
          successfully rebuffed my efforts.
          Frankly, this is very disappointing. It appears that some shortcuts were
          taken on the way to JSP 1.1 support, and the result is a very hard-coded,
          inflexible implementation. As I have not seen the implementation myself, I
          hate to assume this, however one could posit that the term "interface" was a
          foreign concept during the implementation, other than as some annoying
          intermediary reference requiring an immediate cast to a specific Weblogic
          class, which in turn is apparently required to be final or have many final
          methods, as if being optimized for a JDK 1.02 JIT.
          I am sorry that I don't have any positive suggestions other than to use a
          URL object to come back in an execute the necessary "include" directly. You
          lose all context (other than session) and that can cause its own problems.
          However, you can generally get the URL approach to work, and you will
          hopefully avoid further frustration.

Urgent Solution needed--Problem in JSP compilation with JDK 1.5 and JDK 1.6

Hi,
I m using JDK 1.5 and Tomcat 5.0 the problem is that after starting server when I m going to access my application at that time instead of displaying HomePage it directly display the blank page on screen.
After analyzing tomcat log I have found that there was a problem with JSP page compilation.
The exception logged in Tomcat Log is given below
An error occurred at line: 1 in the generated java file
The type Collection is not generic; it cannot be parameterized with arguments <? extends E>

After getting this kind of error I have analyzed my code furhter then I came to know that there was problem with static include tag.
In my jsp page I have used following line which is the main cause of error
<%@ include file="top.jsp" %>If I ommit this line then it is working properly.
Instead of static include I have used jsp:include also.
Still I m getting same problem.
We have to migrated from JDK 1.5 to 1.6 and Tomcat 5.0.28 to 6.0.14, still same problem is there.
We have tried a lot but didnt get success to overcome this problem.
If anybody having any solution then ur each reply will be appreciated.
Thanks in advance..........!!!!!!!

Hi "mshanu" and "amit" Thanks for ur replies Here I m posting the code of "top.jsp"........!!!!
<%@ page errorPage="errordisplay.jsp"%>
<table cellpadding="0"
       cellspacing="0" height=50 width=780>
       <tbody>
         <tr class="header">
           <td class="logo"><IMG SRC="assets/Logo.gif" BORDER=0 ALIGN=top></td>
           <td align="right"><span class="applicationtitle"><%@ include file="/contents/logo.htm" %></span><br>
           <span class="companyname"><%@ include file="/contents/companyname.htm" %></span></td>
         </tr>
        </tbody>
</table>To include top.jsp I have tried
<jsp:include page="top.jsp" flush="true">
</jsp:include>
         AND
<%@ include file="top.jsp"%>but none of this worked.
If I remove the include then It is working properly.
But I need inluded file too so that I am wondoring for the solution.
This problem seems very wiered to me. I dont know why it is happening.
This problem is started only when I used the TOMCAT 6.14.
Is it the bug of TOMCAT 6.14 or What somebody Plz help.
I got stuck here.........!!!!!!!!!!
It doesn't seem any problem with top.jsp. As per my thinking the problem is there in include due to that it doesn't compile the JSP page in Tomcat 6.0.
Earlier I am having same code running on the Tomcat 5.0.28 and JDK 1.5.0.
But problem occured when I have used Tomcat 6.x...!!

ADF cache problem

Hello,
I'm developing a web application with an ADF tree accessing to a Content DB repository. When I deploy the application and navigate to the tree everything look fine. The problem occurs, when the content of the repository changed outside of the web application (e.g. a file will be deleted with Oracle drive), the tree doesn't display the changes. The only way to get the right state of the tree, clear the browser cache and reload the page again. In my opinion it looks like a caching problem. Putting the following meta information in the html header also failed!
<meta http-equiv="pragma" content="no-cache"/>
<meta http-equiv="expires" content="0"/>
<meta http-equiv="cache-control" content="no-cache"/>
Is there a possibility to disable the caching of such ADF components?
Hope you can help me!
Thanks,
Alex

Qaaws not refreshing query triggered from Xcelsius, maybe a cache problem

Hi,
I'm having a problem with QAAWS and Xcelsius
I'm using a List Builder component to select multiple values in this case STATES from the efashion universe
I use the selected states as values to feed a prompt in a QAAWS query, the qwaas query has the SALES REVENUE as the resultset and in the conditions it has a multi prompt for STATES
When I preview my dashboard, I select the States, then UPDATE the values and then refresh the query with a CONNECTION REFRESH button, The first time I do this it works fine and returns the Sales revenue.
If I add a new State to my selection and then run update and run run again the query with the refresh button, it doesn't work any more and it shows again the value retrieved from the first query
First I thought that the query wasn't triggered by Xcelsius, but by doing some more tests I found that actually the query runs but it returns the value from the first query
I think this is a cache problem , so is there a way to tell QAAWS to always run the query and not use the cache?
thanks,
Alejandro

Hello Alejandro,
QaaWS indeed uses a cache mechanism to speed up some Xcelsius interactions (from XI 3.0 onwards), but your issue should not be induced by this, as cache sessions are discriminated according to session user id & prompt values, so if you are correctly passing prompt values, QaaWS should not serve you with the previous values by error.
Could you specify how you are passing several prompt values to the QaaWS? There might be an issue there, so make sure that:
1. QaaWS query prompt is set using In List operator, otherwise only first value will actually be taken into account,
2. In Xcelsius Designer Data Manager, web service input paremeters are duplicated to accept several input values (you cannot submit you list of prompt values as a list to a single input parameter).
If this still does not work, I'd suggest you debug your dashboard runtime using an HTTP sniffer like Fiddler (available from http://www.fiddler2.com/) which enable you to inspect the sent & recieved HTTP messages with the server, where you should verify which prompt values are sent to the QaaWS servlet.
FYI, you can set the QaaWS cache lifetime for each query, by going into QaaWS edition first wizard screen, click Advanced... button and change value for timeout parameter (default is 60 seconds)
Hope that helps,
David.
