Portal - webservices - portlet

Dear all good morning
I have create a rest webservice with jdeveloper.
It inserts, deletes and updates into HR.Departments.
When i finished with the testing of the webservice i created URL data controls (1 for each action).
I created a jspx page and inserted the 3 data controls as ADF parameter form.
I tested again the webservice with the help of the page and everything works properly.
After all these, I create a portlet entry and a portlet. I uploaded it to my portal and i tested
again. Nothing happened. I cannot insert or delete or update my Departments table.
Can anyone help me
Christos

I saw at the EM 11g (Fusion Middleware Control) that when i run the portlet I am taking this log message
Exception invoking method from CSV data control.
Cause: oracle.adf.model.connection.ConnectionException: JBO-29000: Unexpected exception caught: java.net.ConnectException, msg=Connection refused
Any idea?

Portal Director Portlet

Hi,
I would like to know to make the portal director portlet point to a page created by me and not to geometrixx.
I am deploying the war file on WPS 8 and trying to display my page through the portlet.
I have tried the following:
1. Changing the start path through configuration of the portlet. Doesn't work, it throws an error and the page URL in the address bar reflects that it tries to go to geometrixx login and then the path of my page is appended at the end of the URL.
2. Tried deactivating geometrixx pages.

Hi Yogesh, actually I was trying to deploy the CQ Out of the Box Portlet (CQ Portal Director Portlet) on WPS 8. Anyway, through a lot of trial and error, I got the desired result.
The issue was with the structure. Since, the portlet has locales configured 'en', 'de' by default, it looks for the similar structure. Hence, one needs to disable the locale info add checkbox in the Apache Felix Web Console configuration.
PROBLEM SOLVED.

WebCenter Portal and Portlet support in JDeveloper 11.1.2 version

Hi,
When the WebCenter Portal and Portlet application creation will be available within JDeveloper 11.1.2 version ?
Thanks
Eli

Thanks for your answer.
My Requirements are:
1) Develope a stand alone ADF FACES(JSF 2.0) application
2) Develope a Portal using webcenter- We need to implement portlets by taking some of the functonality that was implemented in section (1) and use the Portlet-JSF bridge to create the portlets.
Basically, we need to support JSF 2.0 standart.
As I understood I must use the JDeveloper 11.1.2 version as it support the JSF 2.0. but what about the Webcenter and the Portlet-JSF bridge to support JSF 2.0 ?
I will be happy to get a clarification for those requirments.
Thanks a lot !

Can anybody guide me on that? Also let me know if anybody can help in using the Preferences as I'm able to load the default preferences but cannot store the preferences with store() method.

Portal WebService User Authentification error

Hello all,
I created a portal webservice similar to the one described in tutorial "Creating a Web Service in Enterprise Portal 6.0".
When I tried to test it in Enterprise Portal Web Services Checker I got the error below:
<b>The User Authentification is not correct to access to the Portal Service com.sap.portal.prt.soap.ContentService or the service was not found.</b>
I already added group Everyone to my service in Portal Permissions and it still does not work.
I read weblogs below but none helped me:
1 - Unable to access portal service from web service..........urgent
2 - IllegalAccessError when calling a WebService
I checked the proxy settings and it seems to be ok.
Does anyone have another suggestion?
Regards,
Mauricio

I found the reason.
I did not check End User checkbox for the Everyone group we inserted into Permissions of the Web Service.

Mauricio

Portal Webservice from Portal Service

Hello community...
I'm trying to build a Portal Webservice from a Portal Service, but the wizard doesn't appear in my Portal Application Object. There are only Portal Components, Portal Services and a RF Component Wizard. Are there any options configuring the NWDS to show the other wizards like the "Portal Webservice from Portal Service" one or do I have an old version of the nwds (7.0.14)?

Hi Ozzie,
in newer NWDS versions this wizard doesn't exist any more.
[http://help.sap.com/saphelp_nw70/helpdata/en/1f/4554426dd13555e10000000a1550b0/frameset.htm|http://help.sap.com/saphelp_nw70/helpdata/en/1f/4554426dd13555e10000000a1550b0/frameset.htm] describes how to create a web service from a portal service.
I personally didn't create a web service by this description however. I just created a normal Java class and created a Web Service out of this class (using EAR deployment).

No option for creating new portal or portlet in BEA workspace

hi, i download workshop102_win32.exe from oracle site and installed the software properly.but after Creating a Workspace i didn't find any option for creating portal web project in the "File-->New-->project".
Their is also no option for creating any portal or portlet also.
so i think i didn't install a propery software for portal development or i need to install any other extra plugins for portal development in BEA weblogic.
So, friends please suggest me where i will find the proper software for weblogic portal development.
I expect your prompt reply, any help will be very appreciated.
Thank you in advance.

1. To have better luck on questions about WebLogic Portal, you may want to post your question in the [WebLogic Portal Forum |http://forums.oracle.com/forums/forum.jspa?forumID=573].
2. are you following any documentation or demo or tutorial/ white paper which asked you to download what you downloaded?
3. About your question, what you installed seems like the Development Tool for WebLogic.
For the WebLogic Portal Software, you may want to go to the following page and click the last link in the User Interaction category.
http://www.oracle.com/technology/software/products/ias/bea_main.html
That link is for Oracle WebLogic Portal 10.3 and gives you the file portal103_win32.zip.
hope that helps!

Plumtree 5.0.2 Portal - Webservice interaction from portlet

Hi,
What is the best way to build to portlet in Plumtree 5.0.2 Enterprise Portal (Now ALUI and Webcenter Interaction) to invoke a synchronous (send-receive) web service from the end user and display the result back on the portal page?
Two options I had in mind:
1) Build a remote application using Oracle ADF and consume it as a portlet in the Plumtree portal. - Saves time
2) Build a remote application using Microsoft SilverLight (UI framework) and consume it as a portlet. - Can reuse existing application
3) Build a standard JSR-168 portlet using Plumtree portlet development framework - Last option if 1 and 2 dont work
Kindly let me know what would be the best approach. Option 4 (if any) is also welcome
Thanks in advance

are you using java or .net? personally i would use a div with some javascript to do an ajaxy call to a webservice that then fills the div's inner html property.

-The WSDL url available is http://localhost:7003/TEST_WEB_PORTAL/producer?wsdl
-Now Open JDev and created WCP Framwork app

Hi,
I tried creating a simple JSF portlet and I can able to register and it is working Fine, but my teammet got the same issue like you :) . While Analyzing what I found is , the location where we created the portlet in weblogic portal. If you created your portlet directly under WebContent folder then this issue is coming up, so try to create the portlet in a folder inside the WebContent folder, say create a folder with name portlets under webcontent and create the JSF portlet inside that portlets folder.
Now start the server and register the same in WebCenter, you will not get that exception. I am going to raise a ticket with Oracle about this issue and get the root cause.
Thanks

1. I added a Private Sharing Reference Property in portalapps.xml of the application -
<application-config>
    <property name="PrivateSharingReference" value="com.pseg.webservice.RetrieveAndValidateUser"/>
</application-config>
2. I modified the Java-Build Path to include the Portal Service Application.
3. I deployed the Webservice par on the portal. I can see the service listed under Applications in
System Administration->System configuration->Service Configuration.
Is there anything i am missing or doing incorrectly?
Points will be promptly awarded for helpful answers.

Hi Lokesh
I created a Portal Service consuming a webservice.
It turns out the Private Sharing Reference that i gave had some fault. That's corrected now.
Now on deploying the Portal Application I created for accessing the service, i am getting the following error -
java.lang.Exception: The parameter Accounts is null before the serialization but in WSDL definition this field cannot be null
Here, we need to pass this parameter "Accounts" as NULL only, for test purpose.
Points will be awarded generously in case of helpful answer.
