Jpf portlet cache?

I've got a jpf portlet, which has a few actions to take the user to different pages. However, if I go through the actions, next time I click on the portlet, it seems to cache it and take me to the last page I went through, NOT the first page I wanted. And the begin method doesn't seem to get executed again. I've tried to change the properties of the portlet(Cahe Expires to 0 second and Cache Render Dependencies to false) but doesn't seem to work. Does any know how to solve this? Thanks!

Page flow Refresh Action is for refresh.You can always specify 'begin' as the value here.
Specifying a separate action lets you do things like goto a specific page if you want to remember the state of the user etc.
If you generate the urls with _nfls=false whenever you click on a page /book then all pageflows get reset so their begin action will be called always.

Portlet caching in weblogic portal 10.3

Hi,
I implemented the following for testing portlet caching.
1) I have one JSR/168 portlet with cache enabled(Render Cacheable property set to true). This portlet displays time.
2) Have another JSP portlet which prints the cache names and size of the cache.
3) Then third portlet which is a JSF portlet has a submit buton
The caching works fine in the JSR/168 portlet.
I used the following code to display cache names and cache size.
String[] cacheNames = CacheFactory.getCacheNames();
for(int index = 0; index < cacheNames.length; index ++ ) {
Cache rcCache = CacheFactory.getCache(cacheNames[index]);
Iterator cacheKeyIterator = rcCache.keySet().iterator();
int cacheKeySize = rcCache.keySet().size();
while( cacheKeyIterator.hasNext() ) {
Object aKey = cacheKeyIterator.next();
Object keyValue = rcCache.get( aKey );
System.out.println( "Cache Name: " + cacheNames[index] + "," + cacheKeySize + "," + keyValue.getClass()+","+keyValue );
The above code displays only the cache names which display metadata of the portal/portlet like portlet preferences, localization details.
But I need to know the cache name which is caching the portlet content and in which form the content is getting
cached(as a value object or as HTML). Any help on this?

Hi,
Could someone pls explain which cache is used to cache portlet content and in which form the content is cached?

Hi,
The Solution is very straight forward.If you are creating a JavaPageFlow based portlet then in JSP you must use beehive netui tag.If you are using simple jsp tag then it will not fullfill your requirement.
Create a pageflow ,in the index.jsp page create a form(with <netui:form action="submitData">) tag.Create two text boxes(<netui:text>) and then create a form bean in the controller which will be associated with the action of the form.
In the controller's submitData action put the value in the request or session and forward to displayData.jsp.
Now create a portlet out of this pageFlow and put on the portal file.
Thanks

Portlet to JPF Portlet Communication

Hi All,
Can someone tell how to communicate from a JSP Portlet to a JPF Portlet.I have
tried communicating from a JSP Portlet to a JSP Portlet using the Event Manager
mechanism.Is there corresponding attribute of Backing File in a JSP Portlet in
JPF Portlet.
cherio,
Mani

Hi Mani,
How do you want to communicate to the jpf portlet from the jsp portlet.
If you want to just use a href, the jpf portlet can be referenced by following
/portal_app_name/appmanager/portal_name_created_in_admin_portal/desktop_name?_nfpb=true&_pageLabel=pageLabelName
Let me know if you have any questions.

Portlet caching

Portlet caching
Scenario: An application consisting of several related portlets on different pages.
Overview:
1- Summary Status page displays summary status in a portlet. The status is obtained from a pageflow call to a database.
2- Detail Status page displays detailed status in a portlet for several objects. The detailed status is obtained from a pageflow call to a database. From this page a call, via a link, is made to an Update Page.
3- Update page contains a form where the status for an object(s) is entered and written to the database.
Functionality:
When the database is updated using the Update Page the status should be "immediately" visible to users who did the update when they navigate from the Update Page to either the Summary Status Page or the Detail Status Page.
Problem:
After updating the database the newly added values are not immediately available to the user who did the update. Other users logging onto the system see the updates but not the updater.
Can someone provide some insight into how I can make the data immediately available? I would think that once the database is updated that a call to a status page, which does a pageflow call to the database, should update the data for the user.
I have turned the Render Cacheable property in the portlets properties to false disabling caching but this has no effect.
Thanks for your assistance.

Simon,
The current version of Oracle Portal 3.0.6.6.5 and 3.0.7.6.2 does not handle web portlet caching as it is supposed to. This issue is fixed in the next release of 9iAS Portal which should be available the early half of this year. I apologize for the confusion in this.
Also, you always use the parallel.jar that comes with your 9iAS Portal installation. The one we provide in the JPDK is for users of 9iAS Portal Early Adopters Release. Please do not use if you are using the production version of 9iAS Portal.

How do I flush the portlet cache?

I have tried using the portlet cache (renderCacheable="true" ) on some data intensive pages and its working fine. When i make changes to to the data i need to be able to flush that cache though so that the portlets show the updated data.
I have tried to find a way to do this programaticly but so far i havent found any solution. How do i do this?

Create a backingFile on the portlet
and from one of the methods (say handlePostbackData)
call
PortletBackingContext.getBackingContext(request).invalidateCache();

How to do the data binding in JPF portlet

Hi
I want to know how i will get the data from Controller action to my JSP page in JPF portlet.
is there a use of JPF portlet implicit objects
or Portlet Context??

You can use ActionOutput in Controller to push data to JSP page and use pageInput in JSP file to catch that data to display.
For example:
@Jpf.Action(
          forwards = {
               @Jpf.Forward(
                    name = "index",
                    path = "/tinhvan/portal/index.jsp",
                    actionOutputs = {
                         @Jpf.ActionOutput( name = "userList", required = true, type = java.util.List.class)
     protected Forward begin() {
          usersList = getUsers();
          Forward fw = new Forward("index");
          fw.addActionOutput("userList", getUsers());
          return fw;
<netui:body>
     <netui-data:declarePageInput name="userList" type="java.util.List"/>
        <netui:form tagId="searchForm" action="search" method="post">
                 <netui:select tagId="user" dataSource="actionForm.performedUser" size="1" title="Chọn người dùng cần theo dõi">
               <netui:selectOption value="">-- Xem tất cả --</netui:selectOption>
               <c:forEach items="${pageInput.userList}" var="user">
                    <netui:selectOption value="${user}">${user}</netui:selectOption>
               </c:forEach>
          </netui:select>
        </netui:form>
</netui:body>Regards

Reset Portlet Cache

Hi!
I am building a portlet that display results of a SQL query (defined on admin settings). The portlet is used by many users. Caching works fine except on occasions when the user is required to view the latest records.
Is it possible to reset the portlet cache (I.e.. Users clicking on a button on the portlet to invalidate the cache?)
I am interested in maintaining a public cache. The documentation recommends having a unique, invisible setting (eg. current time). My concern is that, this approach would be similar to private caching (having multiple combinations of cache rather than one per portlet).
Is there a header that can be sent to invalidate the cache? I see that postbacks (.net) ignore caching.

Hi, Mark -
Exactly. That should prevent the portal from caching portlet content. It may be more expensive
short-term, but you get far more control from ASP.NET caching.
If someone from BEA disagrees w/ this or sees a better way please let us know. This topic has
come up a few times and the last suggestion was to implement programmatic caching like this
through code...
Thanks,
Eric
------- Mark Breen wrote on 2/14/06 6:20 PM -------Hi Eric,
Thanks for your response!
when you say take Plumtree/BEA framework out of the equation, do you mean to set the caching
min, max to 0 on the portlet registration and use ASP.NET cahcing only?
Cheers!

Page and Portlet caching possibilities - Portal 10g

On most of our portalpages we have at least 2 separated areas.
In the first area there is a menuportlet which depends on the users access rights.
Second area shows an item that is rarely changed.
Is there any possibility to cache this page on "systemlevel for x seconds" and
the menu on "userlevel for x seconds" ?
Now some facts about the pages:
Our portel contains over 1000 pages.
These rarely changed contents are informations not often read by the same user, because the most info they will get are news, reports or anything else like this.
Thanks for any help!

Hallo Juergen,
Menu portlet: you can edit the portlet instance settings and configure system level caching for x seconds.
For the entire page, configure user level caching for y seconds.
This holds true if x>=y.
If y>x, set the menu portlet timeout to the same as the page timeout.
Hope this helps,
Peter

JSF portlet Cache

Hi
In my application home page i have 3 JSF portlets & some static contents, I would like to cache the same. I used afc:cache in 10g, but im not able to use it 11g. Also how to cache JSF portlets?

When creating JSF portlets in Jdeveloper, he asked if the portlets need to be cached.
This will add en entry in the portlet.xml. You can also add it manualy:
<expiration-cache>300</expiration-cache>But normaly these things will be cached on a higher level using a webcache or some sort.

Which Cache is the Portlet Cache?

Greetings,
We're using WL Portal 8.1 SP2.
When using the portal administration tool, I can add or change a portlet on a page, but it does not always show up immediately. It sometimes takes a redeploy to see it.
Is this a cache? Can I use the Cache Manager in the CONFIGURATION SETTINGS-->SERVICE ADMINISTRATION section of the admin tool to create a cache configuration to be used to flush it? If so, what is the name of the cache?
Thanks,
--steve

I believe that I have narrowed it down to a Web Server sitting in front of the BEA Portal. If I download the page directly from the BEA Server, the changes appear immediately.
Thanks for your response.

Portlet Cache Scope

When using Workshop 8.1 sp2, and we set the cache property of a portlet to true, what is the scope of that cache? session, application, etc...?

session.
This puts a lot of stuff in the httpsession. be careful as the session size, in a clustered environment can become an issue.

Page, portlet cache

Hello, folks,
I have an annoying technical issue for refreshing page.
I have a page: PageA, in PageA, there is a portlet : PortletB, which will have some links to BEA CMS. The workflow is like:
1) people click PageA link
2) people see page with PortletB
3) there are 3 links in PortletB
4) people click link in PortletB
5) PortletB refresh to load content and render contents.
Now, I click PageA and want it to show the orignial PortletB, which has three links only, however, when I click PageA, PortletB just refresh the current contents, I cannot go back Previous PorletB with 3 links.
BTW , portletB is a pageFlow.
Could someone give me some hints?
Thanks very much.

What patch version are you running on - prior to 30982 debug=0 didn't work properly.
After and including 30982 there is debug=0 and debug=1
pre-3.0.9.8.2
enabled by adding "&_debug=1" to the end of the regular PPE URL. The resulting page will be cached, including statistics, if the page is marked with the "Page + Contents" style of caching. All portlets, and the page meta data, are passed the "_debug=1" flag which can alter the behaviour of the portlet, and typically alters the caching characteristics.
3.0.9.8.2
enabled by added "&_debug=0" to the end of the regular PPE URL. The resulting page is guaranteed to be assembled at the time of request. There is never a retrieval of a previously assembled page. No debugging parameter is passed though to either the portlets or the page meta data so the cache statistics are more accurately reflected.
changed "_debug=1" behaviour so that resulting page is guaranteed to be assembled at the time of the request, but the parameter is passed through to portlets so the caching information often changes.
3.0.9.8.3
added "Login Meta Time" section. This information, relating to the use of a provider on the page with a login frequency other than "Never", is now broken out from the page meta time.
In each version, the debugging flag will produce a web page annotated with performance and caching information

Java portlet caching problem

I am facing portlet state problem.
Problem is below,
step 1. I opened a page in java portlet, then set some filters for my list boxes and for check boxes, then executed i got all my search results,
then closed the page.
step 2. opened page again, which opens in the same portlet as step 1, then this portlet displays the page with results instead of default page
I tried setting _nfls parameter to false in request URL, but still it is loading the page with state as in step1.(i'e page with filters set and with results)
Any suggestions on how to overcome this?
