Portal Application Sessions Issue

Hi,
We are getting the following exception when we are trying to open the task item from UWl . Initially it works fine but after a 15-20 times, we are facing this issue.
403 error u201CMaximum number of application sessions for this user session has been exceededu201D
Can anyone let me know where can we set the sessions / how to delete it.
What is the best way to fix this issue.
- By configuring opening of the UWL task item within the same screen . We dont want to do this and want to open it in new browser only.
Thanks,
Uma

Could you please tell me which netweaver version is this system?
However try the following:
Please go to: http://<your host name>:<port>/nwa
Select the application module "webdynpro/resources/sap.com/tcwddispwda", select Web Dynpro Properties tab and select default from the corresponding table.
In the Full Details section, navigate to the property "sap.max.session.limit" and change the value that you would like to configure and save it.
Best regards,

Weblogic Portal Application Upgrade Issue

Hi,
I'm upgrade my portal application from WLP 9.2 to WLP 10.3 using the workshop.
I create a new workspace in 10.3 and then use the import option -> (general) Existing projects into workspace -> choose my 9.2 workspace project.(Check the "copy projects into workspace" option)
I see upgrade pop up letting me know that I need to upgrade my portal web project.It is understandable it is first time I'm importing my 9.2 portal app into 10.3 . But if i close the 10.3 workspace and reopen it again, i'm been prompted again for upgrade which had already did earlier.
What is happening here? something is missing. Can some one guide me here?
Thanks!

Did you get any solution for this we are also facing same problem. please let me know the solution if you have any

Sessions issues and slowness of application

Problem Description: We are experiencing some session issues in our application built using ADF. After one of our recent deployment we are seeing some issues which are causing session values spilling across sessions. For example if a user A is logged in and searching with a value 123 in a certain form in the application, at the same time if another user logs in and opens up the same form he would see 123 value retained in the form. There are other similar issue which are being encountered like concurrent users being logged out randomly, the login name of one user showing up in another users screen, etc. This has recently been encountered and had not been seen until SIT. We are now into UAT and this hence impacts the business hugely as there is a team of end users who the business had made available to see the demos and test furher but with the above explained, the testing is on a stand stilll. We hence see an urgent response on this and request that this be dealt with on utmost priority. in addition to this we have been seeing poor performance especially while accessing the application from IE, mozilla and iPad/Safari browsers. We have also observed that some of the custom images being used in the application UI (residing in a specific folder) are not being cached while others in ARF folder are being cached. Images which are not being cached have been identified as a cause of additional delay in loading of pages.
We are using Jdeveloper 11.1.1.5 .Adf technologies used are ADF faces, we have also used View objects(ADF Business Components) to fetch the data.

This all sounds like you have a problem with application module pooling.
Have you tested your app with am pooling turned off?
Check [url http://tompeez.wordpress.com/2011/07/08/jdev-always-test-your-app-with-applicationmodule-pooling-turned-off/]JDev: Always Test Your App with ApplicationModule Pooling turned off for more input.
Once you've sorted out his problem we can talk about the performance. There are a couple of posts and blogs around about this.

Deployment issue of webcenter portal application

Hi,
While deploying webcenter portal application I am getting below exception:
Caused By: java.lang.ClassNotFoundException: oracle.webcenter.lifecycle.listener.FeatureMetricApplicationListener
This is what I did:
1. Created a separate schema using webcenter RCU.
2. Extended domain for 'custom managed sever' using oracle.wc_custom_portal_template_11.1.1.jar template.
3. For 3 new data sources (custom), used new schema details.
4. Restarted domain.
5. I could see my new managed server running, however there was no machine associated to it and I did that from console.
Now when I deploy my webcenter portal application on this managed server I am getting problem.
I tried below solutions but no luck:
1. Tried deploying ear from console but same error.
2. Tried deploying ear on admin server but same error.
Kindly suggest if I am missing any step...
Thanks!

it's working now.
this is what i did:
1. commented following in weblogic-application.xml file:

2. then i started getting following error:
[03:36:42 PM] Weblogic Server Exception: weblogic.application.ModuleException: Failed to load webapp: 'myapp'
[03:36:42 PM] Caused by: java.lang.ClassNotFoundException: oracle.webcenter.portalwebapp.servlet.PortalErrorServlet
i found this PortalErrorServlet servlet entry in web.xml file, so i commented that as well.
n now application is deployed.
and i got this clue when i deployed sample application available on yannick's site, which got deployed successfully and that application didn't has entry for above classes...
thanks.

Problem in Webcenter Portal application with High Availability changes

Jdeveloper Version: 11.1.1.5
JROCKET
MDS is pointing to IBM/DB2 database.
Weblogic Domain 10.3 with 1 cluster - 2 manage servers.
BigIP - Load Balancing
Database: IBM DB2
I am facing below issues in webcenter portal application after making high availability changes.
1. "A connection to the server has failed" Status - 12152
12031
404
2. Because of Inactivity, session is timeout - ADF_FACES_30108 exception.
The above exceptions are occuring randomly in the application. It occurs either at login page or inside the application clicking on any link/button.
I have made high availability changes as per the below blog:
http://rimmidis.blogspot.com/2012/02/adf-application-running-on-clustered.html
Any help is really appreciated

Fixed "Because of Inactivity.." popup message by adding more tokens. The PS4 Webcenter portal application default value for CLIENT_STATE_MAX_TOKENS is 3, we increased to 15 that fixed the popup message.
There was another popup message "Connection to the server failed, with status = 404, 12152..., which resulted in a bug in the product. The PortletServletContextListener was throwing classcastexception and that was causing this popup message.
Once again, we have noticed these popup messages only when we tried to make our application high available.

Users locks during portal application

There are two back buttons on the portal application
- one on the transaction
- one in the top right corner of the screen.
When the user is in the middle of a transaction and uses the back button located on the transaction level to back out of the transaction, any locks in SAP are correctly backed out; however, if they use the Back button located in top right of the portal screen, the users locks up within SAP. Whenever this locking occurs, the only way we have found to get through it is to have their SAP sessions manually killed or they have to wait 30 minutes for the transaction to release in SAP - obviously, neither of these are acceptable solutions.
I'm hoping that there is a setting that we can use to force a cancel of the transaction in SAP when the user performs either of these scenarios.
Can anyone propose a solution to address this issue?

Hi,
Pls check in the system Admin->Monitoring I think we can find in this.
Or try to check in User Admin->Keystore admin

Calling Oracle Ebusiness Forms from a Webcenter Portal application

Hello All,
Would there be any known/standard procedure of calling Oracle EBusiness Forms from a Custom WebCenter Portal Application. The issue we are facing currently is that we are successfully able to call an Oracle EBS Forms as a GO Link from the application. The problem is when there are multiple links to open different EBS Forms. Multiple instances of the Forms sessions are created. We would like to have only one. We are trying to mimic the Oracle EBusiness Home Page / Landing Page.
Any pointers are much appreciated.
Thanks,
Nachi

Hi.
Are you using Portal or Framework Portal?.
In case of <noscript> is generated by JAVA internal classes and the unique way to change the message is with a Non supported workaround overriding a CoreBundle class.
About the af:skipLinkTarget usually is in the Page Template. The default templates has it in next snippet:
<f:facet name="center">
 <af:skipLinkTarget>
 <af:facetref facetname="content">
 </af:facetref>
</af:skipLinkTarget>
</f:facet>
If you're using default Templates then copy them and remove the af:skipLinkTarget tag from the copied one and assign it to the Portal.
I hope it helps.
Regards.

Fetching data in R/3 via portal application(JSPDYNPage)

Hello Everyone,
I want to fetch data in R/3 server via portal application(JSPDYNPAGE) & display that data as an output of the portal application in TABLEVIEW format. Can anyone guide me on this (I:e-How to connect to R/3 server via portal component & fetch data & display the same). any similar application developed for a reference will be of great help.
Thanks,
Chetan

Hi Chetan,
I hope you know how to create a JSP Dyn Page, anyway I will explain it briefly.
Open NWDS->File->New->Create a portal application project->Specify the project name
right click on the project->New->Create a new portal application object->Portal component->Select JSP dyn page-(By default it creates class and all)->this is available under description on the right column-
Now goto the Java page->see the functions->attach zip and jar files(HTMLB plugin)
->Right click on the project->goto properties->Java build path->Add external jars->Select com.sap.portal.htmlbbridge.zip and htmlb.jar
This is how JSP page is created.
Now we want to do establish connection with R/3. That I will discuss in the next session.
Award points if this was helpful......
All the best for you
Regards,
Arun Jacob.

SSO between Portal Application and Portal Admin Tool

Hi All,
We have a requirement for implementing SSO between a Portal application and
Portal admin tool.
We are using WL Portal 8.1 SP4.
Here is the reason for this requirement -
A user logged-into Portal Application needs to login to Portal Admin tool to
do some admin activity. We want to provide a link in the portal application
using which the user can directly login to the Portal Admin tool without
having to enter the credentials again.
If someone has any info on how to implement this, can you please point me in
the right direction.
Thanks,
~Deepak

Hi,
When creating PP you have 2 options
PP used for compiling and PP used for Building
You create PP with all the libraries into Developing/Compiling Other DCs
And another PP with all the libraries into can be packaged into other build results (SDAs).
Once you have these 2 PP in place you add the DC as used DC.
And this should resolve the issue.
Hope this helps.
Cheers-
Pramod

Application session time out

Hello
i have an application deployed on weblogic 11. after 30mins the application session times out.
1.how can increase this time.
2. can this be done in weblogic since on the application side there is no configuration for the time out.
please assist me
Thanks

Hello;
On middleware the default should be 3600 seconds.
To change :
Login to the WebLogic Administration Console
Under domain structure click Deployments
Click on the "em" Enterprise Application
Click on the Configuration Tab
Set "Session Timeout (in seconds):" to 7200 ( or whatever you want )
Hit the Save button to save your changes in the deployment plan
I would make sure an idle timeout in not set in the database profile as well.

Problem in creating a build.xml for weblogic portal application

Team ,
I am facing problem in creating the build.xml using weblogic.BuildXMLGEN tool .
a) Below is the structure of my portal application
SrcCode
--- .metadata (eclipse plugins folder)
--- B2BApp ( Ear Content)
--- b2bPortal ( portal related file(controllers,jsp)
--- b2bsrc (java src)
b) Now I executed below utility to generate the build.xml "
java weblogic.BuildXMLGen -projectName B2BApp -username weblogic -file build.xml -password welcome1 F:\srcCode"
c) Based on the above step , build.xml got generated .
d) when I execute "ant compile" target from the command prompt , I see the below exception
ant compile
Buildfile: build.xml
compile:

+[wlcompile] com.bea.util.jam.internal.javadoc.JavadocParsingException: Parsing failure in F:\b2bNew\b2bPortal\src\portlets\b2b\dmr\Picker\PickerController.java at line 58.+
e) I suspect , the problem is bcoz of classpath issues , as I generated build.xml donot have the references to dependent lib's.As build.xml looks like below :
+<target name="compile" description="Only compiles B2BApp application, no appc">+
+<wlcompile srcdir="${src.dir}" destdir="${dest.dir}">+
++

Please help me to reslove these issues .

a) this is a upgrade project [ upgrading from wlp 8.1.4 to 10.3.2 ]
i.e we are using weblogic portal 10.3.2 version.
b) Searched some sites/forums regarding the above error, and it says something related to "jwsc" ant task [ i.e while compiling a webservice(JWS) ], but we see this error while compiling a normal controller(jpf) class :(
c) we are using "ant compile" target which internally calls wlcompile task , while executing wlcompile this error is thrown .
Help Appreciated

Classpath error in portal application

Hi
first problem
when i am going to deploy the sample portal application for example displaying the "Hello world" message in the output, so i am getting the classpath error as displayed below.
"The project was not built due to classpath errors(imcomplete or involved in cycle)"
can any one help where should i change the classpath and all to deploy the portal application successfully".
second problem
when i am going to write the code in the dynpage in the portal for example
suppose if i want to add group to form then i type
formobjectname.groupname;
when i press . the entire list of possiblites are not apperaing in the list.
pls help on this two.
will award max points, if i slove
Regards
Sunil

Dear Sunil,
To answer your second question first:
You ae'nt getting the list of methods/possibilities because the correct package/class is not imported. e.g. If you do not include com.sap.security.api.* you will not get the list of methods associated with any class falling under that package.
The first problem: I really suggest that you download classlocator from sourceforge.net. It is easily plugges into NWDS. Double Click the error message and see it completely. I guess you would get one more message stating which class cannot be found. Once you install Class locator, you can easily type the class in the application and it will automatically add that Jar file in your classpath thus solving your issue.

Howto deploy content via portal application

Hi all,
currently i'm integrating some external web apps into my EP6.0 SP2. Therefore I use the application integrator plus some iview und system templates.
I've developed the templates as components in a portal application in the portalapp.xml.
But now I'm searching for a way to deploy not only the templates but also real content, e.g. instances of my templates with a portalapp.xml.
At this time I must make the concrete iviews based on my templates by hand.
Is there any doc outside the targets this approach? What I've found is the Portal Runtime Guide, whith an overview of portalapp.xml structure, but nothing concrete.
Regards
Steffen...

Thanks for the reply ... here is the answer to your questions along with an update to some more information after trying something different
Did you deploy the WebCenter Managed server from Jdeveloper
I am deploying the application to the WebCenter Managed server from JDeveloper.
What managed server did you deploy it to - a custom server that you created?
Yes this is a custom Managed Server (called MindFlow). At the time of your response the only two servers up and running on WebCenter was the AdminServer and MindFlow.
Did the deployment go through?
Yes
Are there any errors in the managed server log when you access the page?
Yes these where the errors showing that it could not connect with the metadata via the repositories.
Now for the update:
I went ahead and started up the WLS_Portlet managed server that comes with WebCenter. When I did this I got the following error:
WSM-04509: cannot initialize the connection to the data store
I then deployed the Portlet Producer Application to the WLS_Portlet from JDeveloper. I then grabbed the url for the newly created portlet producer and updated the connection on the Portal application. After doing this and updating the portal.jspx file, I then deployed the Portal application to the MindFlow managed web server. I then brought up the portal.jspx page via a browser and was able to bring back results. The only issue now is that while doing this I got multiple MDS errors (including the initialize error above) and not sure if I can ignore these or not. One of the errors received was as follows:
oracle.mds.exception.MDSException: MDS-01258: The value @MDS_CLASS for property class-name is invalid.

JAR files required for Portal Application

Hi Experts
I am currently migrating my custom Masthead application from NW 7.0 to NW 7.3. However, when I migrated the PAR into EAR using migration tool from Portal and imported this EAR file into NWDS7.3, the JSP pages in it shows error. Also when this EAR is directly deployed on the NW 7.3 system, it gives Portal Runtime exception.
<%@ page import = "com.sapportals.portal.prt.session.IUserContext" %>
<%@ page import = "com.sapportals.portal.prt.component.*" %>
<%@ page import = "com.sapportals.portal.prt.service.laf.*" %>
<%@ page import = "com.sap.security.api.*" %>
<%@ page import = "com.sapportals.portal.prt.service.license.ILicenseService"%>
<%@ page import = "com.sapportals.admin.wizardframework.util.ILocaleListService"%>
<%@ page import = "com.sapportals.portal.navigation.*" %>

<%@ page import = "com.sapportals.portal.prt.util.StringUtils" %>
<%@ taglib uri="prt:taglib:tlframework" prefix="frm" %>
The errors shown in the JSP page are due to missing JARs. But I am having trouble in locating the required JAR files on the server. Can anybody tell about which all JARs are required and where i can find them??
Also the imported Framework library is not accessible in the application thus there is error "Can not find the tag library descriptor for "prt:taglib:tlframework"".
Can anybody tell me what i am missing here??
Regards,
Deepak
