PDK guide

While the PDK examples that are currently provided by ORACLE are sufficient for learning the fundamentals is there any plan on the part of ORACLE to actually write a book on the PDK? I can see it as an excellent way of promoting the product to the average PL/SQL programmer. If not a book at least better documentation online that can be used.
Thanks,
Rajendra V Auradkar

Rajendra,
I'd like to hear a little more about your thoughts on why a book would be better than a hosted resource.
Initially, the PDK (for Portal 3.0 beta) was a bound volume. Customer feedback was that this was unwieldly and many didn't bother getting started because they were intimidated, not only by the extremely technical content, but its size.
We update the PDK monthly. For the PDK November, the design decision was to become more of an online magazine style resource than a bound volume. To succeed, we started from a basic level, breaking content into shorter articles.
Over time, we will continue to add content and I'd like to hear your (and the rest of the community) feedback on what you'd like to see.
I hope that new developers, though, feel that the work is accessible and easy to implement.

PDK-Struts Application requires pdkstruts.jar & pdk-struts-html.tld

Hi All,
Scenario is this, that I've created a pdk-struts application via JDeveloper with normal struts taglibs, and deployed it to Oracle Portal 10.1.4. default-action tags specified action.do is working fine and displays the welcome page within portlet region but after clicking any button within that welcome page opens a new browser page within same window and the URL pattern changes too.
I want this to be executed within portlet region.
Another problem is this, when I tried to use pdk-struts-html.tld within application;
first warning within JDeveloper is this; Metadata Namespace for pdk-struts-html is not loaded, all entries are fine, and within Portal after successful deployment it gives an error (500 Server Listener Error) on viewing that portlet body.
I want these issues to be resolved as soon as possible.
Or if anybody knows about pdkstruts.jar and pdk-struts-html.tld with latest versions, plz do tell me the site-url to download these things.
Plz help me out about these issues.
Thanks in advance.

Look in the Building Struts Portlets with Oracle Jdevelper section of the Oracle Application Server Portal Developers Guide. You need additional jar files besides the pdkstruts one. Also, look in the server logs to see more detailed messages about why it failed, it will help you debug.

Oracle 9iAS 9.0.2.1.0 patchset and PDK

I'm patching Oracle 9iAS as described in Metalink note 215882.1. The readme file for the bundled patchset 9.0.2.10 says that the set can not be installed when Oracle 9iAS Developer Kits are installed. I have installed PDK Release 2 (9.0.2). What am I supposed to do.

For all administrator guides, go to:
http://download-east.oracle.com/docs/cd/A97329_03/index.htm
As for a configuration tool, all there really is is an installation "cookbook". It is really helpful. It goes through pre-intall task, installing 9ias, and post-install tasks.
For Windows:

Problem Deploying Oracle PDK Portlet to Oracle Application Server 9.0.4.0

I have a big issue trying to deploy a pdk portlet I have created in JDeveloper (10.1.2). The application is very simple, it consists of 2 JSP's (call them Select.jsp and Display.jsp) and 1 Java Class (Call it DoEverything.java).
The architecture of the system is VERY simple. The Select.jsp is a simple drop down list that is embedded in an html form, with the options in the drop down populated by a method call from DoEverything.java. Once the user selects an option and hits submit, he is sent to the Display.jsp, which is a simple html table that is populated by another method call from DoEverything.java. (Basically the whole system is a simple "view" of a given table in a DB based on the option selected in Select.jsp).
The system works perfect in JDeveloper, where I created it using the Oracle PDK Java Portlet wizard. However I'm running into a problem when I try and take it over to the Application Server. The main documentation I have been following is the: Oracle® Application Server Portal Developer's Guide and in particular the section 6.6.2.4.1 Creating a Connection to Oracle Application Server Containers for J2EE where it explains how to connect to the App. Server. The line "The steps that follow describe the procedure for deploying to a standalone instance of Oracle Application Server Containers for J2EE. For information about deploying to a full Oracle Application Server instance, please refer to the Oracle JDeveloper online Help system." is the one that is bothering me the most as I am trying to deploy to a full instance of the Oracle Application Server, but I cannot find anywhere that walks me through this in the online JDeveloper help.
Anyway, currently we ftp the appropriate JSP's, Java Class, provider.xml and provider properties files to their respective directories on the Application Server, register the provider and reboot the Http Server. (This has worked before except for the fact that when the user selected an option from the Select.jsp and the request was then sent over to the Display.jsp based on the form action the Display.jsp wasn't recognized. We figured the provider.xml file needed to be edited in this case in order to know where Display.jsp was being kept). In any event nothing seems to be working at the moment and my main concern is that it maybe we should be deploying as EAR/WAR (both of which I'm not super familiar and my second main concern is that it seems most people use JavaBeans and Struts and all sorts of different API's whereas here I just have a fairly simple Java Class back end that connects to the database and creates an object based on the attributes contained in the database (1 object for 1 unique row in the DB) and I want to be sure that the way I have developed this should still work with the Oracle AS. I'm hoping its just a matter of getting the directory structure straightened out and editing the provider.xml file to include all the JSP's.
Sorry for the long post, but if you could address my two main concerns and possible give me or point me towards a good thorough walk through of deploying a simple system (oracle pdk java portlet) like I have developed to the App. Server it would be greatly appreciated !
Thanks a lot.

Basically I started to develop this system inside Oracle AS and then when it came time to passing a request to a new page, it crapped out on me on the App. Server. So instead of trying to fix the problem there and then I continued to develop outside Portal and inside Jdeveloper. After a week or two once all my stuff worked perfectly I try and take it back into Portal but only the first JSP of all my Portlets would show up, because as soon as I would submit a form and the action directed me to a new page and Portal would be lost/confused. Obviously I shouldn't have done it that way but none the less...
So now I'm reading through the documentation you pointed me towards and it seems I have to qualify my parameters and then "attach" them to the url which the form will pass to the actioned page. I'm importing numerous classes (...urlUtils, etc) in order to qualify the parameters and then build this url without affecting any parameters currently present that my portlet does not own.
What I'm rambling towards here is all this separation of logic and presentation and the whole nine, implies different people can develop different parts of a 'system' mostly independant of one another...so in my situation I shouldn't in huge trouble yet, since underlying everything is a working system. My issue is with oracle and the App Server. If I take my code which works great outside of the App. Server and I fully qualify parameters and make sure my form actions are constructed using the UrlUtils in order to fully qualify them as well, and then I make sure page parameters are mapped to the proper portlet parameter values....should my system work on the App Server (assuming everything is done properly)....or am I still missing something.

Web Service portlet using pdk documentation issue

Hi,
I have followed the instructions in
http://portalcenter.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/ARTICLES/how.to.build.web.services.portlets.html
on how to build web service portlets.
I have successfully deployed the WS portlet and can happily call my web Service (RPC style) passing a set of parameters which I have formatted using a stylesheet.
However, every time I refresh the page within portal, it recalls the WS with the previously submitted parameters. Also, if I switch between view and edit mode in portal, it again calls the WS with previously entered parameters.
Can I stop this happening either through a setting in portal or code in my Stub class. (Stub class below)
Thanks alot
Joel.

Hi Joel,
You can enable caching for your portlet. There are three types of caching you can use: expiry, validation, and invalidation-based caching. You can learn about your options in the Enhancing Portlet Performance with Caching section of the Portal Developer's Guide.

Peter

Migrating and Enhancements in .par files created with PDK

Hi ,
We had deployed .par files created using PDK on EP 5 to EP 7 and they are working correctly.
Now there are some enhancement which are coming up in the applications.
I wanted to know whether it would be better to go to NWDS to modify those applications or would PDK be the right approach?
I am not sure what is the PDK file for NW2004s?
Appreciate if some one can guide on which approach should i take for enhancements.
Regards
PN

PDK use of HTT

Hi
I need go get some clarification this some central issues here.
First, in the installation guide after installation of HTT, there is a reference to something called The Template Manager what is that?
It is a separate program or part of Portal, how do I start it?
I know this might be a stupid question, but I really dont know anything about a Template Manager.

http://www.portal.nl/pls/HTT/HTT_PUBLIC.template_mgr.show
This will be the htt managers location where 'www.portal.nl' is your url to the portal site.
In this manager you can store your HTml Tenplates (HTT) that you want to use withing your portal.
HTT is not a part of portal, but can be used with it. There is a table 'gen_portlets_tab' in which each row represents a HTT portlet.
more info on the subject is located at:
http://otn.oracle.com/products/iportal/files/pdk/integrat/htt/docs/Index.html

How to install PDK 6.0...?

Hi, currently I have PDK 6.0 that contains the epa file "com.sap.portal.pdk.PortalDevelopmentKit-2004-03-25.epa", I am wondering if there is a "How To Install PDK 6.0" guide anywhere?
I'm new here, so please advise on how to reward points after question is answered.
Thanks so much,
Baggett

Hi Baggett,
To install PDK you should have EP installed in your WAS.
If EP(Enterprise Portal) is installed and it is running, then through SDM tool you can deploy the PDK.
To run SDM the default location will be
<install drive>:
usr\sap\J2E\JC00\SDM\program\RemoteGui.bat
It will open the Software Deployment Manager GUI Window.
Select SDM GUI and login , enter password and defult will be "sdm". after login select deployment tab and select the first icon i.e. Add SCA/DCA to Deployment List, it will open a pop-up window where you have to select the .sca file location for PDK software that you have., then select next button, then press start button to start deployment.
after complition of the process press confirm button and pdk will be deployed in the EP server.
After that you have to assign the Java Developer Role in the User Administration to the user and when you logged on as that user in the portal then you will have to access the PDK resources.
Thanks,
Hari

Customising CATS Webdynpro or PDK or BSP

Hi SDN Gurus,
Currently we've have configured CATS application in EP using ITS.
Because of performance related issues , we are planning to develop the application based on BSP/PDK/Webdynpro.
As I am new to BSP/Webdynpro/PDK your thoughts on this will be very much useful to me.Please guide me which option is better performance wise for CATS.Request you to provide any useful link/ info in this regard
Thanks in advance.
Regards,
Ganga

Hi Sujesh,
To achieve this create Development component.
In your component controller of WebDynpro Component add your database related code.like getting connection,registering connection etc.
This approach is much like all java applications connecting with oracle.
You can use JDBC connector service. Here you can configure Java based thin drivers to connect to Oracle Database. Advanatages of doing this are you can configure several connection paramaters and also do a rough monitoring of the connection usage.
For connection u can use this code:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
Regards,
Pooja.

JDeveloper setup steps for pdk java and portlet container - ver 10.1.2

Hi fellows,
Can someone please point to some really not-confusing guide to setting up pdk java and portlet containers on jdeveloper 10.1.2.
Problem is, I went through several documentation links and they keep pointing around to steps that are followed if you wish to have a stand-alone OC4J. JDeveloper 10.1.2 also had a preconfigured OC4J with it. I wish to make use of that and configure it for Oracle Portal editings for version 10.1.2.
thank you for your help.

I have some documentation that I tried following:
For PDK-Java installation, here is the link to documentation.
http://www.oracle.com/technetwork/middleware/ias/installing-089002.html
However, what is confusing is what to do if you just wish to use the preconfigured OC4J container that comes with Jdeveloper 10.1.2.
Experts, can you please clear this out please?
Thanks!

Drag&Relate enabled iViews with PDK

Hello everyone,
I want to create a Drag&Relate-enabled iView with PDK on EP 6.0 SP6 but I did not find any guides about this topic. Does anybody know how to do this?
thanks in advance,
Jens Harzer

Hi,
the new, enhanced, pure Java, Drag&Relate is being released at part of PP SP7 (Stack 05), and now is available to use as part of the Portal Platform.
It is very easy to create content that enable Drag & Relate using the simple iView Wizard (both 'Query iView' and 'Application Integration iView') as well as the Role Uploader - they all create content that is 'unification enabled'.
of course, it is not that simple, and one needs to define the right systems, use the correct templates and so on, but, it is possible (as well as using the newly Context menu notion instead of Drag & Relate).
I encourage you all to consult the Portal Platform documentation to see how it's like, we are planning for more roll out activities soon.
Thanks
Ori

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 to install PDK?

Hi,
I just downloded the pdk from SDN. It has come as a rar file called "NetweaverDeveloperCockpit_NW04SP12.rar" I don't know how to install it in the portal I have. Please help me how to install this rar file.
Thanks,
Bhagya.

Here are the instructions from the PDF included in the rar file:
Technical Description and Configuration Information
Purpose
The following procedure describes how to install the Business Package Netweaver Developer Cockpit (PDK) in a portal and how to configure the portal so that the example iViews work correctly.
Prerequisites
You have installed a standard SAP Enterprise Portal either locally on your personal PC or on a test server. Optionally you have installed SAP NetWeaver Developer Studio.
You have uninstalled older PDK versions completely with the Archive Remover tool and Portal Content Studio.
If you use MaxDB as Database, you have to deploy MaxDB JDBC Driver manually and register it at the portal. For more information see SAP Note 773401
Installation
Import the Business Package for the Portal Development Kit into your portal installation.
The business package is delivered in SCA format and you have to use the Software Deployment Manager (SDM) to install it. For more information, see SAP Note 731386
Import the attached ICE transport package via the Content Management->Content Exchange->Package upload. Import the the file DeveloperContent.zip As a result you see the folder DeveloperContent under the KM repository documents.
Post- Installation Steps
Configure the Portal for the Netweaver Developer Cockpit
The connector example iViews in the Portal Development Kit connect to SAP Backend System with the system alias PDK_R3_BACKEND.
To run these examples you must define a system object for a test SAP Backend System in your system landscape and assign the following aliases: PDK_R3_BACKEND
The JDBC example iViews use a JDBC database with the alias: LocalMaxDB
To run these examples you must configure the system object LocalMaxDB or define a new one and add in your system landscape and assign the following aliases: LocalMaxDB.
The Dummy Object Based Navigation Examples (without real Backend connection) require that you the System Alias PDKDummySystem to the System PDKDummySystem
According to your authentication policy you also have to maintain Usermapping and afterwards you have to configure Distributed Query Engine (DQE) for the systems. See SAP help portal and tutorial forfurther information.
The System Landscape Directory SLD has to be maintained for the WebDynpro Examples which require a backend connection. See Web Dynpro Tutorials for details.
For more information on how to create system objects and assigning aliases, see Enterprise Portal Administration Guide 6.0->Portal Platform->System Administration->System Landscape->System Landscape Editor.
To ensure that you have the permission to run all the applications in the business package, you must be assigned to the following portal roles:
Role ID - Purpose
Super Administrator - for all Portal operations and permissions
Administrator - Optional
com.sap.pct.pdk.JavaDeveloper - The NDC role
ContentManager (optional)- For importing ice content.
Restart Server or iView Runtime Container
This is recommended to deploy all portal archives. Known SDM limitation in NW04.
Authentication of WebDynpro Content Administrator and SLD
WebDynpro Content Administrator and System Landscape Directory need a SAP WebAS Java Server Administrator authentication. Usually the portal administrator is not assigned to the Java Server role Administrator so username and password with the correct permissions for these iViews have to be provided.
Create user in SAP Backend System
The example iViews connect to the SAP System using the username you are currently logged on to the portal. You must create a user in the SAP System with the same user ID as your portal user or define any user mapped to the portal user via usermapping.
Portal users accessing an SAP System via remote function call (RFC) must have a user or be mapped to a user in the SAP System with the following authorizations.
Authorization object S_RFC with the following field values:
ACTVT: 16
RFC_TYPE: FUGR
RFC_NAME: RFC1, RSAN, SDIF, SDIFRUNTIME, SDWZ, SKBW, SPR4, SPRT, SRFC, SSCV, SURL, SUSO, SUSW, SU_USER, SWOR, SYST, SYSU
The following authorization is only necessary for Drag&Relate:
Authorization object S_TCODE with the following field value:
TCD: SPO1
