How to know the logout url in Java PDK

Is there any method that can give us the logout url of SSO using java PDK?
Thanks in advance,
Tony Cruz

Thank you for the replies. But what i really want to do is a login portlet that can show me a link to logout, and i want to use this portlet in all projects that my company is in, so the code of this portlet must be 100% dinamic, this means that i do not have to know the database schema/passwords, where database is, etc, i thought there was some method in the JPDK that was able to give the link to logout (this is possible for login) but until now i cannot find it. There is a solution for this using a PL/SQL procedure called wwsec_app_priv.logout that lies in the portal schema, this procedure works but i'm not able to redirect the browser to the url i want after logout (in the documentation they say its possible and that there is a parameter called p_done_url that can do this, but in the procedure signature this parameter its not implemented) so right now i'm stucked in this one, and im not sure if i can use the 100% dynamic approach with good results.
Thanks

Web Service to do Java PDK .setProperty() and .store()

I had posted this in the EP Content Development group, but received no response. Sorry for the cross post but this is relatively urgent for me.
I am working on a Portal Component in the PDK for .NET which will take values selected from a CheckBoxGroup, concatenate it to a string and write that to a single Personalization preference.
However, the PDK for .NET does not support writing Personalization preferences to the PCD. Thus, I have determined the solution to be:
Make a Portal Service that takes a value and writes it to the Personalization of an iView. Basically it needs to simply do a:
IPortalComponentProfile profile =
request.getComponentContext().getProfile;
profile.setProperty("selectedVal", myData);
profile.store();
Then this will be converted to a Web Service. However, how will the Web Service know what iView its writing Personalization for?
I've searched and searched and come up with little clues here and there that I've somewhat pieced together but no concrete solutions. Please help. Thanks! --Shibli

Hi,
I took a look at the portal javadoc and there is another getComponentContext method that gets a string, urn, perhaps that will help.
Take a look <a href="https://media.sdn.sap.com/javadocs/NW04/SP12/runtime/com/sapportals/portal/prt/component/IPortalComponentRequest.html#getComponentContext(java.lang.String)">here.</a>

Where to find EP5.0 SP.5.0 Java PDK ?

Hi,
We could not find the java role file(.epa)for EP5,SP5 in SAP site .It seems they might have stopped support for that version.If anybody has that file, Kindly give us the link.
Kind regards.
Syam.

Hi Dieter,
Yes I did a typing mistake. I meant to say EP5.
By the way you were right. I went through some of the related links and concluded that you were right. PDK6 will not be supported by EP5.
I guess the reason is since the .par file which I was talking about, is meant to be run with PRT (Portal Run Time) of EP6 version. So EP5 will not support it.
Thanks for information and making me read documents related to PDK
Hi Shyam,
Well dear, thanks for rewarding points!! I guess you need the PDK 5 for your EP5. But I wonder why are you going for EP5. I personally feel that you must update your portal to EP6. There are various add-ons in EP6 than that of EP5.

Localization in Java PDK

Hi,
I have a PDK for Java portal application.i need to localize it for different languages like German,French etc depending on the language user selects from a given dropdown in this portal application.
I checked the getResourceBundle method.It does not take any parameter and returns the resource bundle depending upon the locale of the logged in user.
Is there anyway to achieve Localization based on user selection from the dropdown in the application. ?
Warm Regards
Saurabh

Hi Maxime.
To take your Resource Bundle from Java classes follow next steps:
- Register in faces-config.xml your supported and default locale. Remember that you have to have a bundle file with a suffix yourPortalBundlePackage.PortalBundle_[locale] that you registered.
<locale-config>
<default-locale>es</default-locale>
<supported-locale>en</supported-locale>
<supported-locale>en</supported-locale>
<supported-locale>es_ES</supported-locale>
</locale-config>- Register a var pointing your Resource Bundle: For example:
<resource-bundle>
<base-name>com.merchan.portal.PortalBundle</base-name>
   <var>portalBundle</var>
</resource-bundle>- Now from Java Code you can access to your bundles with next util method:
public static String getStringFromBundle(String key, String varName) {
      FacesContext ctx = JSFUtils.getFacesContext();
      ResourceBundle rb = ctx.getApplication().getResourceBundle(ctx, varName);
      return rb.getString(key);
// USE
JSFUtils.getStringFromBundle("HOME","portalBundle"); // If you have a JSFUtils and ADFUtils register this static method there. These classes are very usefulRegards.

Java PDK Bugs and Issues

Here are some bugs and issues I've run across using the JPDK that I thought other
developers should be aware of. The following information comes from using JPDK
1.1 with Oracle Portal Version 3.0.6.3.3 Early Adopter on Windows 2000.
1) Do not use a colon character (':') in the String value returned by the method getTitle( Locale l ) in the class Portlet. Registering the provider will appear to succeed, but when you view the Portlet Repository you will get the following error message:
An Unhandled Exception has occurred. ORA-06502: PL/SQL: numeric or value error:
character to number conversion error
Your provider and its portlets will not appear in the Portlet Repository when this error occurs.
Perhaps other characters will cause this error as well.
2) The Provider class method initSession() is supposed to propagate the array of returned Cookies back to the browser. The Cookies are never propagated to the browser. This is a huge road-block for our application and we need to have this problem fixed as there is no workaround.
3) There is a limit to the number of portlets you can have per provider. I initially wrote a provider class that managed 19 portlet classes. However, after registering the provider only 17 portlet classes were loaded by the provider and/or displayed by the Portlet Repository. I had to create a second provider to manage additional portlets. The second provider worked out fine for me because I have 5 portlets that are for "administrator" users only. Moving these portlets left 14 portlets for the first provider to manage.
Note: I don't know if this error occurs using the provider.xml method of implementing a provider and its portlets. My provider and portlets are implemented directly using the Java class API's.
4) Sometimes I will receive the error "Meta data missing for portlet ID=<number>" when a portlet is rendered for the first time. This error does not occur often but when the error happens two conditions are met:
a) The portlet is being rendered for the first time
b) The HTTP and Web Assistant NT services have recently been started.
This error is obviously caused by some timeout but increasing the timeout values
for both the provider and the portlet has no effect. This error may be restricted to the NT platform.
The following notes are not bugs but issues to be aware of:
1) Make sure you have the "sessiontimeout" parameter defined when declaring the initArgs of a servlet in the zone.properties file and you intend to register your provider with a "Login Frequency" of "Once per User Session". For example:
servlet.urlservlet.initArgs=debuglevel=1,sessiontimeout=1800000
If you leave off the session timeout, Oracle Portal will call your provider's initSession() method for every request constantly generating new a session ID.
2) Currently there is no means to check whether a ProviderUser has administrative
privileges. This feature would be extremely helpful for restricting which portlets a user has access to when the provider's getPortlets() method is called.
3) Currently there is no Java API for storing user and global preferences in the
Oracle database. The JPDK provides a PersonalizationManager class but the method
of storing the preferences needs to be implemented by the developer.
The default Personalization Manager persists user preferences as a file
to disk. However, this method opens up security holes and hinders scaleability.
We got around the security and scalability issues by using Oracle's JDBC
driver to persist user and global preferences to custom tables in the underlying Oracle database.
I would appreciate hearing from anyone who has run across the cookie propagation issue and has any further insights.
Thanks...

David,
Thank you for your feedback on the JPDK. The information you provide helps us understand how customers are using 9iAS
Portal and its development kits. I apologize for the delay in getting back with you. Since you are using the Early Adopters
release, we wanted to test a few of the bugs and issues on the production release of 9iAS Portal.
1) Using a colon character (:) in the String value returned by the method getTitle(Locale l) returned the ORA-06502 error is a
known issue. This issue actually occurs within 9iAS Portal and should be resolved in the first maintenance release scheduled
for 9iAS Portal.
Waiting on reply from Nilay on #1
2) The Provider class method initSession() not propagating the array of returned cookies back to the browser is an issue that we are currently working on. This bug has been fixed for most cases in the first maintenance release. A 100% fix of this issue is still being worked on.
3) The limit to the number of portlets you can have per provider was an issue in the Early Adopter release, but is no longer an issue with 9iAS Portal production. Upgrade to the production release and you should no longer see this problem.
4) The error "Meta data missing for portlet ID=<number>". I have not seen or heard about others receiving this same message. For this error, can you upgrade to the production version and let me know if you still receive this error message. At that time we can check for differences within the configuration.
Not bug, but issues......
1) You have made a good point with the sessiontimeout parameter. The JPDK uses servlet 2.0 APIs which does not provide access to the sessiontimeout. Currently, you will need to specify the sessiontimeout parameter in the zone.properties file.
2) This is true. Currently there is no means to check whether a ProviderUser has administrative privileges. This is on our features list for future enhancements.
3) This is also true. The DefaultPortletPersonalizationManager was created as a default runtime for developers not used to writing portlet code. It allows developers to write portlet code without concentrating on the underlying framework. Once a developer becomes more experienced with the JPDK and portlet environment, we encourage them to create their own
customization manager. This includes changing how the portlet repository is stored or changing how the user customization is
handled and where it is stored. You have no limitations as long as you follow the guidelines of the PortletPersonalizationManager interface.
I hope this information helped. Again, we appreciate and welcome this type of feedback, it helps us not only locate bugs and issues, but also helps prioritize our enhancement list.

Can you install the Java PDK in the portal that runs on Unix?

Our Netweaver Portal (EP6 sp20) is running on a Unix box.
Can I not install Portal Development Kit (PDK) - 60.14.0 ????
It says in the installation guide:
"The PDK is like the SAP NetWeaver Developer Studio released and supported for Windows platforms only."
I thought Business Packages were Platform Independent ???

yes you can, at your own risk

How can I use LogOutComponent programatically in a Java iView?

Hi,
Can someone point me to the jar file(s) that I need to reference in my portal application project (Java PDK) to use LogOutComponent? Which ones do I need and where can I get them
I got the class file 'com.sap.portal.navigation.masthead_core.jar' from the Portal server but am not sure if this file is the only one that I need to use to incorporate LogOutComponent in my code.
Also, can somebody tell me that how can I call this component from my AbstractPortal Component to call logout programatically? I am not using JSPs and would ideally not like to redirect the response to the URL of this component but rather use the object in my Java code. Sample code to help with this would be appreciated.
Thank you,
- Vik.

Hi there,
To log a user out of the Portal I decided to go the route of: UMFactory.getAuthenticator().logout(req, res)
Code is below.
Thanks for your replies,
- Vik.
<code>
IAuthentication Authen = UMFactory.getAuthenticator();
HttpServletRequest req = request.getServletRequest();
HttpServletResponse res = request.getServletResponse(true);
//logoff user from Portal
Authen.logout(req, res);
</code>

Passing Parameters between Java Portlets

i hava java portlet and it does a search... the search result appears within the portlet region.... but i want to be able to click on the search button and take it to another portal page and have a portlet that contains the result of the porltet... how is that acheivable...

Well i've done this with java pdk portlets, but I guess the principle is the same everywhere.
Where are 2 types of parameters, qualified and unqualified ones. In your case you have to
use unqualified ones, so that your other portlet can read a parameter which is set by your search portlet.
Also add <passAllUrlParams>true</passAllUrlParams> to your provider.xml, inside a portlet tagof the result portlet, so yo are able to read unqualified params aswell.
Othee options are using sessions or a persistant datastore, eg database

Why use JPDK rather than Pl/SQL PDK

Hi All,
currently I have deployed all my portlets using the Pl/SQL PDK which is very good, but slow to create portlets in that it takes time to create each portlet.
what are the advans / disadvans to using the Java PDK to create portlets ?
I perfer to wqork at the PDK level rather than the portal application level as I have found the PDK portlets much more portable / scalable when installoing on different servers.
Any information on the JPDK would be very helpful.
thanks Darragh

Hello,
Thanks for your answer, it's very helpful. I'm still looking for a strategy to link the VO and the EO though. I thought about registering the EO in the VO as normally, but not use it in the query (obviously) then override the ViewRow and do some funky stuff in the various 'set' methods to do something like:
setAttributeInternal(index, value);
// somehow push the value in the EOHowever, programatically pushing the value in the EO from the VO seems trivial so far, but I'm not sure how good the result will be. I'll test it to see how well it works, but if there's any documentation about that subject that you know of, it would be appreciated.
Thanks,

Need help in post-installation steps of the PDK

Hello,
I have installed Java PDK 6.9 instead of 6.2.
At the post-installation steps I need to:
<i>The example iViews in the Portal Development Kit connect to a SAP System with the system alias PDK_R3_BACKEND.
To run these examples you must define a system object for a test SAP System in your system landscape and assign the following aliases:
1. PDK_R3_BACKEND Reference to a R/3 system of your custom landscape.
2. PDKDummySystem Reference to provided system OBN-3. PDKDummySystem.
WebDynpro Reference to provided system WebDynpro.</i>
My question is: When I create this System, which type template should it be and which configuration besides the above aliases should it have?
Roy

Hey Aviad,
Yes I did, in my case I've installed PDK SP 9 over SP2 which is prohibited. If this is your case as well do the following:
1) From the Undeployment tab of the SDM select the com.sap.pct.pdk..
components.
2) Using the Archive remover tool which can be accessed from
System Administration > Support > Portal Runtime > Administration
Console > Archive Remover --> Remove the portal applications with prefixcom.sap.pct.pdk...
3) Navigate to Content Administration > Portal content > Content
Provided by SAP > Platform Add-Ons > Developer Content
and remove all the contents below this folder.
4) Restart the server
After this you can deploy the SP9 business package using the SDM.
Hope it helps,
Roy

PDK or WebDynpro for complex UI creation and re-engineering

Hi all,
For our requirement, we need to create complex UI design and post customization (registration, create order based on different conditions and validations and so many things).
Please help me to take proper decision to choose development technology that suits for our requirement.(Webdynpo, PDK(java),PDK(.net), Flex.)
Thanks
Deviprasad.

Maybe you use the CAF for the project? You shall then be able to use any technology you want to use or are comfortable with and then integrate the different objects as part of a process.
