Caching issue in jsp or servlet

I am not sure where I should post the issue that I have. I have a j2ee web app (struts) running on Apache Web Server + Glassfish + MySQL. My server has multi core.
The problem is that whenever I insert a new data or delete it from a table, I don't see the change right away. Sometimes, I see the change. Sometimes I don't. It's very inconsistent.
If the old data is cached in JSP, I shouldn't see the change in log file, but I do see it even in the log file.
For example, I have a page managing user's folders. when I delete a certain folder name from jsp page, this folder is deleted from a db table. but when I refresh the page, I still see the folder name that is not supposed to show up. or when I go to a different page and come back to this page, I don't see it. The behavior is very inconsistent.
If it's a browser caching issue, I don't think that I should see it in the log file, but I still see the folder name(which is supposed to be deleted) in the log file.
I am including these lines in all included jsp pages.
response.setHeader("Cache-Control","no-cache");
response.setHeader("Pragma","no-cache");
response.setDateHeader ("Expires", -1);
does anybody have any opinion about this?
It's hard to debug it and describe the behavior.
But it would be very helpful if someone who had a same experience about this explains about this and tells me how to fix it.
Thanks.

Servlet cacheing issue?

hi
i'm having a slight problem i believe may be due to cacheing.
i'm calling a servlet within a frame that displays a generated pdf file using certain values and so forth.
the problem is that it appears to be chacheing the servlet and never reloading it as it should given values change etc.
i'm using tomcat 3.3.1 and apache web server. i tried adding the following :
response.addHeader("Pragma", "No-cache");
response.addHeader("Cache-Control", "no-cache");
response.addDateHeader("Expires", 1);
to my servlet but that had no effect. adding the http meta equivalents to the frame-set page, also had no effect.
another interesting point is that this only occurs using the apache and tomcat combination. it doesn't happen using IIS and tomcat. could there be a setting in tomcat or apache i've neglected?? perhaps some other code to avoid this?
any help would be greatly appreciated.
thanks
Takis

use:
response.addHeader("Expires", 1);
instead of:
response.addDateHeader("Expires", 1);

Deploying a WAR file containing .jsp and servlets (also uses JNI)

Deploying a WAR file containing .jsp and servlets (also uses JNI) on Windows 2000
We had problems making it initially work on Sun ONE Web Server 6.0 Service Pack 1 because of lack of good iPlanet Web
Server documentation on deploying such files.
This is how we went about it:
1) Make one of the servlet and JSP (must call another Java Class) web application (.war) examples work with iPlanet Web
Server.
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\HelloWorld\HelloWorld.war
and
C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
a) Go to your Web Server Administration to deploy the application using GUI Web Application Deploy.
(We usually use command line, we experienced some issues with the GUI version, but maybe it is fixed in the new Web Server
service packs)
From browser, open http://yourserver:8888/
Click on Select a Server:Manage
Click on Virtual Server Class
Click on https-yourserver
Click on the Web Applications Tab
Then, click on Deploy Web Application
Enter the following -
WAR File On: Local
WAR File Path: C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Application URI: /jakarta
Installation Directory: c:\iPlanet\examples\jakarta-examples
By clicking on OK it deployed the application.
I can verify that it is deployed by selecting "Edit Web Applications" and I see the following entry:
Edit     /jakarta     c:/iPlanet/examples/jakarta-examples
Also, c:/iPlanet/examples/jakarta-examples should have the similar following directory structure ..
- [images]
- [jsp]
- index.html
- [servlets]
- [META-INF]
- [WEB-INF]
- [classes]
- [tlds]
- web.xml
- index.html
I restarted the server and accessed it using the following URL from my IE browser:
http://yourserver/jakarta/index.html
Then I clicked on the JSP Examples and tried some JSP examples.
b) Alternatively, you can also deploy the same example from the command-line.
Make sure C:\iPlanet\Servers\bin\https\httpadmin\bin\ is in your path
wdeploy deploy      -u /jakarta
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\jakarta-examples
          C:\iPlanet\Servers\plugins\servlets\examples\web-apps\jakarta-examples\jarkarta-examples.war
Restart the web server (I don't think you have to restart, but .. might as well).
2)Deploy your web-application
My Foo.war has the following structure.
You can use jar tf Foo.war to look at the file contents from command line (assuming you have JDK installed and the bin is
in your PATH)
Foo.war
- [META-INF]
- [WEB-INF]
- web.xml
- [classes]
- Bar.class
- MoServlet.class
- [lib]
- ThirdParty.jar
- [natlib]
- extlib.dll
- foo.jsp
Here is our application scenario:
foo.jsp uses a class call Bar (it is not in any package). The Bar java class uses classes from ThirdParty.jar. The
ThirdParty.jar in turn uses JNI to load library extlib.dll. foo.jsp also calls /servlet/Mo as well.
Now to deploy it, do the following:
(a) Make sure that within foo.jsp, you import the Bar class ( I don't know why you have to do it, but if you don't you get
JSP compile error).
<%@page language="java" import="Bar" contentType="text/html"%>
(b) Check web.xml (for Servlets)
Within web.xml, make sure you have the following mappings:
<servlet>
<servlet-name> MoLink </servlet-name>
<servlet-class> MoServlet </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> MoLink </servlet-name>
<url-pattern> /servlet/Mo </url-pattern>
</servlet-mapping>
(c) Deploy the application
Using command line:
wdeploy deploy      -u /foo
          -i yourserver
          -v https-yourserver
          -d c:\iplanet\examples\foo-dir
          Foo.war
(d) Change web-apps.xml file (for picking up ThirdParty.jar)
It is located in
C:\iPlanet\Servers\https-yourserver\config
You should see something similar to following after successful deployment.
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true"/>
Change it to look like following to pick up the ThirdParty.jar
<web-app uri="/foo" dir="C:\iPlanet\examples\foo-dir" enable="true">
<class-loader reload-interval="300"
          classpath="C:/iPlanet/examples/foo-dir/WEB-INF/lib/ThirdParty.jar"
          delegate="false"/>
</web-app>
(e) Change jvm12.conf file (for JNI)
It is located in
C:\iPlanet\Servers\https-yourserver\config
Add or uncomment the following lines:
#optional - just helps with instrumenting the jsp and servlet code
jvm.include.CLASSPATH=1
jvm.enableDebug=1
nes.jsp.enabledebug=1
jvm.trace=7
jvm.verboseMode=1
#required for JNI
java.compiler=NONE
jvm.classpath=.;C:\JDK1.3.1\lib\tools.jar;C:/iPlanet/Servers/plugins/servlets/examples/legacy/beans.10/SDKBeans10.jar;
jvm.option=-Xrs
jvm.option=-Xnoagent
# not sure if this is needed for iPlanet web server
jvm.option=-Djava.library.path=C:/iPlanet/examples/foo-dir/natlib/ -Djava.compiler=NONE
(f) Change magnus.conf file (for JNI)
We HAD to change this file in order for ThirdParty.jar file to pick up the native C++ code using JNI. Apparently, the
iPlanet Web Server doesn't pick the Environment Variable Path. Because when we had the directory containing the DLL just
in Path, it didn't work.
Change Extrapath directive:
ExtraPath C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
to
ExtraPath c:/iPlanet/examples/foo-dir/natlib;C:/iPlanet/Servers/bin/https/bin;${NSES_JRE_RUNTIME_LIBPATH}
(g) Apply changes from the Web Server Administration Console and Restart the web server.
You should be able to see the behaviour that you want from your application.
http://yourserver/foo/foo.jsp
Hope this was helpful!!!

The cache issue about indexcol function

Hi Experts,
We have one requirement as below,
Firstly, we have some columns prompt created by JAVA in external portal page, not OBIEE internal prompts,such as Year, Month,Day.
Secondly, we have one report contains one dynamic column which showes the lowest selected level value.
For example,
When users muti-select value in Year, and not select Month,Day, so this report will display as below:
Dynamic--------Sales
2010-------------1000
2011-------------2000
When users muti-select value in Year and Month, and not select Day, so this report will display as below:
Dynamic--------Sales
201001-----------100
201002-----------300
201101-----------500
When users muti-select value in Year , Month, and Day , so this report will display as below:
Dynamic--------Sales
20100101--------50
20100202--------80
20110101--------100
So we have one method to solve this requirement, but faced new cache or update issue immediately. More detail information as below:
We create one temp table which has one flag column ,
when users select Year level, it will record 0,
when users select Month level, it will record 1,
when users select Day level, it will record 2
Then import this temp table into physical layer, and create session init block like below:
select flag from temp
Finially, we create new indexcol column in BMM :
INDEXCOL(VALUEOF(NQ_SESSION.FLAG),Year,Month,Day) and drag it into presentation layer.
When users select value in Year or Month or Day, and the flag will be record into database.However, the dynamic column in report will not be changed.
I must click "Reload Server Metedata" firstly, it will show correctly.(Users do not click this )
Is there any better method to solve cache issue? Or any other better methods for solving this requirement?
Thanks very much.
Note: I have disabled the cache in temp table in physical layer.

Sorry to bother you again, I found I was wrong in describing my problem. I found out that I sent the CiscoIPhoneExecute xml to the phone last time, not the CiscoIPhoneImageFile xml.
The CiscoIPPhoneExecute xml is like:
http://192.168.1.2:8080/test/push2phone.jsp?action=get"/>
And "http://192.168.1.2:8080/test/push2phone.jsp?action=get" returns the CiscoIPPhoneImageFile xml, like this:
Image Title goes here
Prompt text goes here
0
0
http://192.168.1.2:8080/test/pngs/attention.png
so when I send the CiscoIPPhoneExecute xml to a phone, the phone will display the file attention.png on the screen with the sound chime.raw, then I press the "exit" button, the attention.png on the screen disappears. But if I then send the CiscoIPPhoneExecute xml with the "http://192.168.1.2:8080/test/push2phone.jsp?action=get" that returns the CiscoIPPhoneImageFile that contains a different png file, for example "warning.png", the "attention.png" will appear for a short time during the time when "warning.png" is downloading, then "warning.png" appears. I have no idea why that happens. I don't want to see "attention.png" when I'm sending "warning.png". What can I do?
I've tried to directly sent the CiscoIPPhoneImageFile xml to a phone, everything goes well, no "cache" problems. but I have no idea how to add the sound "chime.raw". I want the png files to be sent like short messages with sounds. Please help!
Thanks a lot.

About cache issue when using push2phone and callerino

I have made push2phone and callerino functions working well,but the issue is when we push messages to the phone,the phoen always displayed the message sent last time firstly then the message this time was displayed,seems there was cache issue,so does the callerinfo function.I have no idea about where the cache issue occurs,also how can I let the message be displayed as "tab" method on the phone? Please help !Thanks in advance.

Pdf caching issue

Hi,
I have a serlvet which calls a series of classes which generate a pdf on the fly. Once created on the server, the servlet then calls response.sendRedirect("path to .pdf");. This all works fine. My problem is when I change the data which appears in the pdf and generate it again through the same servlet (with the same filename). The second time the pdf is opened in the clients browser, it contains the first/original pdf data, until I refresh the browser and it generates it again with the updated data. This, I'm guessing, is because of a caching issue. However, in the calling servlet, I set both Cache-Control and Pragma to "no-cache". Is there something I'm missing? Thanks
   public void doGet (HttpServletRequest req, HttpServletResponse resp)
   throws ServletException, IOException
      resp.setHeader("Cache-Control", "no-cache");
      resp.setHeader("Pragma", "no-cache");
      ...//generate pdf on server
      resp.sendRedirect("path to file");
   }

I don't know if this applies to pdf's but for HTML I have scrounged the Internet and come up with this:
    public static void disableCaching(HttpServletResponse response)
        response.addDateHeader("Expires", 791589600000L); // Wed Feb 01 00:00:00 EET 1995
        response.addHeader("Cache-Control", "no-store,no-cache,must-revalidate,post-check=0,pre-check=0");
        response.addHeader("Pragma", "no-cache");
    }Most of the horror in that is due to Internet Exploder. Different versions of IE require different magic spells. Googling for "no-store no-cache" etc finds more on the subject.

Interesting single sigon application project using jsp and servlet....Help.

A customer login's to my website using Enterprise login. I am supposed to have a link on my website to this other website(that also uses our Enterprise login details but hosted by other vendor/company on their server), and when I click this link the customes should automatically get logged in to this other website and get a welcome page(instead of login page).
Below are the sequence of steps that the other website wants me to perform to get to his welcome page(i.e bypass his login page).
FYI, I am planning to build a jsp page with a link to this other website. Can some body tell me how should I build the application(i.e) how jsp and servlets be build to interact to perform these operations. Any hep is greatly appreciated.
1.When a user clicks on to other website link(available on my website), the browser generates an HTTP GET request to the Other website's session servlet. User's name is one of the parameters of this request.
2.Other website receives the HTTP request and generates a unique session identifier for this user. An HTTP response to the end-user is then sent. The user's name and the session identifier are passed back as parameters in the redirect URL.
3.The browser sends the HTTP request (GET) to the Verification Service that was specified in the redirect message. The parameters (user name and/or session id) will be passed as URL parameters.
4.The Verification Service(of other website) authenticates the user. A redirect URL to it's sigon servlet(with parameter's User id and key) is then sent back to the user's browser.
5.The end-user's browser will perform the redirect (performing an HTTP get operation to Other website's signon servlet with the username and the digest key).
6.The other website will check if the parameter's passed is the same as the one passed earlier, if the user is who he says he is then he is redirected to the main page of the application.
7.The browser will then redirect the user to Other website's main page (welcome.jsp).
There seems's to be many calls to this other website that needs to be performed behind the scenes once a user clicks the link on my website.
Please suggest and help me out.........

Why are you trying to build a whole federated single sign on framework from scratch when you can just use/buy an existing and proven solution instead? There are a lot of security implication and trust issues involved for this so unless you already understand all of those I'd advise you not to re-invent the wheel. There are a lot of products available that do this. Try searching for '<vendor name> Access Manager' or OpenSSO.

Directory Caching issue with Cisco Jabber client for Windows

Hi ,
I am facing cache issue with Cisco Jabber client for Windows. If I do any change related to modification or deletion of contacts in Active Directory/ Callmanager, it does not reflect in the Jabber. Because jabber takes the contacts from the locally stored cache file in the Windows system.
Every time I have to remove the cache file to overcome this issue, practically it's not possible to do the same with all the Widows users. As, if any employee leaves the company and still I can see his contact appears in the "Cisco Jabber client". I have not seen this issue with Android/Apple iOS.
Is there any automated way to remove the cache file?
Here is the detail of CUCM,Presence and Jabber.
CUCM version: 9.1.x
Presence : 9.1.X
Jabber : 10.5 and 10.6

Hello
On our environment we had to install a dedicated Microsoft Certificate Authority "just for Cisco Jabber usage" to house the
Network Device Enrollment Service.
Our certificate for the CUPS were generated on this Certification Authority too.
I discussed this certificate matter with my colleagues this afternoon and nobody seems to remember how these certificates were deployed into the
Enterprise Trust store for the users.
But I think they asked all 400 users to accept the 3 certificates by answering "yes" to the popup instead of using a script deployed by GPO...
I wish you success with that deployment and really hope you have a technical partner that *Knows* this subject.
Our partner left us alone with that unfortunately.
Florent
EDIT: If the "Certutil script method" works, please let me know. This could be useful in our own deployment.

PL/SQL vs JSP vs Servlets

We are in the stage of deciding which language to develop portlets. I lean towards JSP or servlets for the wide array of Java libraries we can use. I think the only advantage of PL/SQL is speed. Thanks.

It depends. If your developers are mainly Java developers, you'll probably prefer building web portlets. But if you have a strong PL/SQL skill set you could choose the latter. Additionally, if you're developing content that is database intensive you may want to build PL/SQL portlets since they transact with the database faster. If you're going to aggregate content from various web sites, using web providers is preferable. It's a matter of choice based on your requirements and preferences.

Sql query cache issue

I am trying to see the log file in Manage sessions for the sql query in Answers. I see that if we run the same report multiple times, the sql query is showing up only the first time. Second time if I run it is not showing up. If I do a brand new report with diff columns picked it is giving me the sql then. Where do I set this option to show the sql query everytime I run a report even if it is the same report run multiple times. Is this caching issue?

It shouldn't.... Have you unchecked the "Cache" on the physical layer for this table? If you go onto the Advanced tab, is the option "Bypass the Oracle BI cache" checked?

WEB u2013 I cache issue.

We have BO XI 3.1 PF 1.7 and SAP BW 7.0 SP 18
We are facing strong caching issue with WEB- I XI 3.1 , what we observed is it cache previously fetched data and does not recognize data been updated in BW Infoprovider ( in our case we have BEx query on Direct update DSO )
I have tried u2013
1. I made caching inactive for that BEx query in BW side.
2. I have check caching setting in BO , they are not helping me much to in active cache in BO
On executing BEx query in BW, I have checked RSRT cash monitor; the query result is not getting cached, and get up-to-date data. Query works perfectly file.
Also observed Events in RSDDSTAT_OLAP table, I could find very well Event 9000. This shows me that BEx query hits database and bring data back.
When I execute BO report on the top of same BEx query, I do not get up to date data , it shows me previously fetched data and does not recognize data been updated in BW.
Now question is where this data being getting cashed , and how to make that inactive to make sure I do get up to date data in WEB-I .
Many thanks for your kind response.

This would be stored in the C:\Program Files\Business Objects\BusinessObjects Enterprise 12.0\Data\servername_6400\storage folder. Try renaming this folder and then testing again. If this allows for updated records, then that proves that the Webi Processing Server is getting the cached data from this directory.
There are also a few settings you can try to disable in the Webi Processing Server settings within the CMC:
Disable cache Sharing (Checked)
Enable Real-Time Caching (Unchecked)
Enable Document Cache (Unchecked)
Cache Timeout (1 min) - sets the cache to expire after 1 min.
Try playing with these settings and see if that resolves the issue.
Thanks

How do I restrict access to JSP or servlet only through SSL Port

Hi
I want to restrict the access to few jsp and servlet only through SSL port,
so how can I block the acces to those jsp and servlet through normal port??? We
are using weblogic 5.1.
Any help on this highly appreciated.

Hi,
To restrict access(56 bits or less). follow the below steps.
1. Go to your Webserver instance ServerManager
2. Click Preferences Tab ------> Encryption Preference
------> There disable "DES with 56 bit
encryption and MD5 message authentication."
for SSL 2.0 ciphers or SSL3.0 Ciphers. Which ever
needed.
3. Save and Restart the Webserver instance.
The above steps are for 4.x version.
Thanks,
Daks.

Getting to next JSP from Servlet

I am getting a 404 when I try to redirect from my servlet to an error page. The code that I am testing is....
catch (SQLException es)
LOG.error("Unexpected error in Login.createUser.Error
message = " + es);
session.setAttribute(Constants.MESSAGE, es.getMessage());
session.setAttribute(Constants.ERROR_TITLE, "Login error: " + Constants.SQL_ERROR);
resp.sendRedirect(Constants.ERROR_PATH);
I have a compiled java class called Constants where the ERROR_PATH is defined as
/** Constant name used in obtaining the path to the error page. */
public static final String ERROR_PATH = "/Jsp/error.jsp";
My JSP pages are located at the root...
myapp
....Jsp
....WEB-INF
........classes
My web.xml looks like this
<servlet>
<servlet-name>errorPage</servlet-name>
<jsp-file>/Jsp/errorPage.jsp</jsp-file>
</servlet>
<servlet-mapping>
<servlet-name>error</servlet-name>
<url-pattern>/Jsp/error.jsp</url-pattern>
</servlet-mapping>
Can anyone point me in the right direction....Thanks

I tend to use a utility method called redirectToResource in particular to redirect from any servlet to any JSP :
/** This method will still work when the server is configured to
*   listen to port 80 rather than port 8080 (default in Tomcat)
public void redirectToResource (HttpServletRequest req,
                                 HttpServletResponse resp,
                              String resourceName)
                     throws ServletException, IOException
   int serverPort    = req.getServerPort();
   String scheme     = req.getScheme();
   String serverName = req.getServerName();
   StringBuffer urlBuffer = new StringBuffer(40);
   urlBuffer.append(scheme + "://" + serverName);
   urlBuffer.append(":" + serverPort);
   urlBuffer.append(resourceName);
    String location = resp.encodeRedirectURL(urlBuffer.toString());
    resp.sendRedirect(location);
}

SharedObject and Caching issues

Background:
     I am working on a project where I am using sharedObject to store data for a favorites list. The project contains 2 swfs, one in AS 3.0 (using Flex 4.5) and the other an AS 2.0 flash 8 project. Basically the AS 2.0 project read and writes data to the shared object and the AS 3.0 project just reads the data.
Setup:
     OS: Windows 7
     Flash Player: 10.3     Browsers: IE 9, IE 8, Chrome 14, and some misc Firefox testing -- Chrome seems to be working the best.
Problems:
     First off it has been extremely hard to get consistent results across different computers so if anyone has a suggestion as to why that would be (other than different browsers, different flash player versions, different flash player settings/global settings and different OS versions) because I have been making sure all that stuff is consistent across devices for testing purposes.
     1. It appears that some computers/browers won't store the shared object at all even though everything to allow it is turned on.
     2. Some computers/browsers will store it, but won't update until I refresh the page
General Questions:
     1. Is the storage of sharedObject object data in a .sol file configured the same in both AS 2.0 and AS 3.0 and if so, would this be a means of communicating between two swfs running off the same domain?
     2. Is it possible to have a browser cache sharedObject data(the .sol file)?
      3. I have noticed as new flash player releases are coming out(especially recently i.e. 10.3) I have had to make a lot of repairs to the actionscipt 2 stuff. Is actionscript 2 support slowly being phased out? Is anyone else experiencing the same problems?
Possible Solutions/Findings:
     I am starting to believe that it has something to do with browser caching since Chrome seems to perform the best and Chrome has performed best when it comes to browser caching issues.
** code is available if needed but since it was working before I don't think it is relevant.

Hello,
#1
are you using explicit call to flush method immediately afer you're writing data to reference to SharedObject?
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/net/SharedObject. html#flush()
If not you could have different data read by different browsers sessions run at the same time (e.g. IE/FireFox both hosting your test Flash movies) - as data are flushed only when given Flash runtime session is to be terminated (e.g. movie is to be unloaded) and in other cases as outlined in documentation.
#2
the SharedObject is reference to binary file stored on local machine by Flash runtime (Air runtime too). It has nothing similar to web-fetched content to be cached:

SecurityDomain and Caching Issues

I am running into some caching issues when setting the securityDomain of an imported SWF to match the calling SWF file and I was curious if anyone had any ideas on how to get around this issue.
Here is the scenario:
A.swf is launched on Domain A, it sends a Loader request for B.swf on Domain B.
B.swf will be updated frequently so caching is disabled, A.swf however can be cached.
B.swf has some ExternalInterface.calls so it requires being in the same securityDomain as A.swf otherwise it will receive a Security Error #2006.
The code I am using for this is fairly straightforward:
ActionScript Code:
var request:URLRequest = new URLRequest("http://domainB/B.swf");
var loader:Loader = new Loader();
var context:LoaderContext = new LoaderContext();
context.securityDomain = SecurityDomain.currentDomain;
loader.load(request, context);
I believe B.swf is inheriting the caching setting of A.swf because it is residing in the same securityDomain. If I make a small update to B.swf and refresh A.swf in a browser it will not load the B.swf updates until I clear cache.
If I get rid of the securityDomain context on the load it will always update B.swf with the most current version, but I run into security issues with ExternalInterface.
ActionScript Code:
var request:URLRequest = new URLRequest("http://domainB/B.swf");
var loader:Loader = new Loader();
loader.load(request);
I have tried appending random strings to the end of the URLRequest while using the securityDomain context but it will always used a cached version of B.swf. I have also tried loading B.swf into a ByteArray then using loadBytes on a Loader but that didn't work either.
Any ideas are appreciated!
