Refreshing Webservices in Search (caching problem?)

Hi,
I've developed some EJBs and deployed them to the WAS. I then created a WSIL Destination in NWA.
In Visual Composer I see the methods in my Search Pane no prolem.
I have since added 2 new methods to my service, deployed them, and tested them in Webservice navigator. Again no problem.
Now in VC I choose my destination and search it. Now it only shows the origonal methods and not the 2 new ones. Has anyone else experienced this and got a work around? If I create a new destination and point it to the WSDL file directly then it works. Surely I don't have to do this everytime I change my web services?
On older versions of VC you had a similar problem which was resolved by turning off client caching in the VC Compiling Options, but this no longer exists in 7.1.
Any ideas?
Cheers,
Russ.

Hi,
Caching of services in VC has several layers:
1. Connectivity layer: VC Connectivity caches results (search and discovery) for better performance. Services search over regestries such as WSIL and SR, has higher importance to cache, since the time needed for the search may be expensive. Clearing the cache can be achieved in two means:
a. Restart the Web Services connector (note: 1088382 or using NWA start-stop J2EE application)
b. disable the caching of the connector (Note: 1123574) - should be used if the backend services definitions are undergoing masive changes, and should be turned off after finishing the massive services definotions development.
2. VC Design time cache: VC stores its own replication of the definitions "VC Proxies" to save rountrips to the backend. The proxies can be viewed in VC managed models (data services) and are stored and re-used per VC DC. The proxies can be manually cleared from the managed model dialog or using the re-import functionlity (prefered) over the infoshape (mouse right click)
Guidelines:
If the service had changed --> use re-import (2)
If services were added/removed --> clear the connector cache (1.a / 1.b)

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.

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..

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...

Thanks for your help,

Hi,
The error is clearly showing there is cache error.
To resolve this..go to SXI_CACHE tcode and do a delta cache refresh or full cache refresh.
That will solve ur problem

ASO cache problem with Windows 7

I have a large base of AS2 classes that support my application. I've been working on it for a few years and I'm very familiar with the ASO cache problem that causes edits to not be compiled. Well, I hit it today and I can't get rid of the old files. I'm running CS5.5 and I used the menu first. Then I manually deleted the ASO files. Then I rebooted the computer and searched the entire C: drive for ASO files and deleted all of them. Nothing worked. I finally renamed one of my class files (and the the necessary edits that flowed therefrom) and that one file was recompiled. Obviously there is a hidden cached file somewhere. I have Win7 Pro 64-bit. Has anyone had a similar problem? The last thing I want to have to do is rename all of my class files or tear down and rebuild my development box. TIA

3.1 is not "fine" and the drivers leave much to be desired.
You will probably need to do a Safe Mode and uninstall, rollback, system restore. Use your DVD for Windows 7.
Not sure of the support issues and details on MacBook Pro 13" as to whether you have graphic driver issue, AppleHFS, or other (and to say 'total hangup' doesn't really lead to what and why).

PI Caching Problem

Hello Experts,
we are faced with a strange problem. We are using SAP PI 7.1 EHP 1 and we have developed some integration processes. Now we have transported our software component to another SAP PI 7.1 without EHP 1. Transport also was successful.
Everything worked fine. Then we did some changes in our software component and transported it again. Now we are faced with the problem that one of our four intergration processes have not been upgraded after the transport. In the sxi_cache the integration process always have the date of the first transport of our software component.
Can anybody help? All cache refreshes and a restart of the PI dont solved the problem.
We also did a copy of this integration process and activated it. The copy is never shown in the sxi_cache. It seem like the integration process doesn't exist. But he is there.
Have anybody ever had the same problem? How you solved this?
Thanks for your help in advance.

Go to http://<host>:<java port>/rwb/sub/cache_monitoring/notification_table and look into problems tab to get more details regarding cache problems on your system.
You can fix the problem by creating a new version of the object in dev and transporting it
OR
Doing a full cache refresh in SXI_CACHE

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.

LoadSound IE cache problem

I see there are a lot of postings on this topic, however I
haven't found any resolutions that are working for me. Here is the
situation. I have a main movie, that loads external .swfs and plays
in a linear way, much like a slide presentation. There are back and
forward buttons, that go from one slide to the next. In each
external .swf I am loading an mp3 dynamically as an event sound in
the first frame. Here's an example of the AS:
this.my_sound = new Sound();
this.my_sound.loadSound("screen2.mp3", false);
this.my_sound.onLoad = function(){
my_sound.start();
gotoAndPlay(2);
This all works fine when I upload the files, clear my cache,
and go to the URL. When I refresh the browser, it stops working.
When I use the forward or backward buttons, it also stops working.
Pretty much any time I try to revisit this external swf after it
initially plays, it won't play at all. I'm assuming this has
something to do with the cache. It's only an IE problem so far as I
can see. I don't have this problem in Firefox. I've tried giving
the mp3 a different extension. Doesn't work. I've tried moving all
the AS to the second frame. Doesn't work. Any help would be greatly
appreciated.
Thanks.

inlineblue and Tracy,
Came across this post while looking for a solution for the
cache problem. I am using Flex 2.0.1.
Q1) From what I understood is adding a parameter to the
AC_FL_RunContent("src", "MainMod?version1.1",...) call in the HTML
wrapper will make sure the latest content is downloaded to the
browser. Does this mean when the next time my MainMod.mxml is
changed, I need to make this V1.2.
Q2) I only saw one occurance of AC_FL_RunContent call in my
wrapper where it is referring my SWF file. This is the only place I
need to keep changing whenever the mxml file is changed?
Q3) Looks like I have to change all Wrapper files (if I have
multiple .mxml files in my project). Is there any we can automate
this?
Do you have a sample that I could take a look at to
understand what needs to be changed to fix the issue?
Appreciate your help.

Firefox cache problem

Hi,
There is an old nasty problem that I finally want to solve:
With Firefox my Apex applications get a cache problem once in a while: The user clicks on a button or tab or a text field etc. and suddenly gets a page with the design mingled up and the functionality broken. With ctrl + F5 (refresh) everything is fine again, but it's rather ennoying for the users. The problem is, some users get that often, others not at all, sometimes it's more, sometimes it's less. For all (internal) users I set in prefs.js the cache to user_pref("browser.cache.check_doc_frequency", 1); for maximum refresh behaviour. So the configs should be the same for all.
With other websites it doesn't seem to happen. Is this an Apex specific problem? Are others experiencing the same? Any hint or solution? I would be glad for some input.
Thank you,
Roger

Never get that problem Roger.
The cache problem I have with firefox is trying to get it to load the latest versions of javascript libraries after they have been changed.

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">

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.

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.

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.

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 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.
