Oracle WebCenter Interaction 10gR3: PTMenu will not be displayed properly

andreas.mersch@gmx.de (andreas mersch) — Wed, 19 Aug 2009 11:38:13 GMT

There is a JavaScript Bug in PTControls.js (/bea/alui/ptimages/imageserver/plumtree/common/private/js/jscontrols/LATEST) if the doctype of the portal page is set to HTML 4.0 Transition. The portlet menus will not be displayed beneath the portlet header, but in the upper left corner of the browser window. To fix this bug you have to add

if (this.popup.style.left == '') {
this.popup.style.left = '' + left + 'px';
this.popup.style.top = '' + top + 'px';
}

to the 'PTMenu.prototype.show' method in line 13688.

Another Oracle WebCenter Interaction 10gR3 Javascript Bug

andreas.mersch@gmx.de (andreas mersch) — Wed, 12 Aug 2009 11:49:03 GMT

There is another JavaScript bug in Oracle WebCenter Interaction 10gR3 (\bea\alui\ptimages\imageserver\plumtree\common\private\jsutil\LATEST\ptutil.js). My current version of this file 'ptutils.js' is 334989. You can find the bug in line 116:

                if (srcObj.Class && (srcObj.Class == 'Array') && (typeof srcObj[i] == 'function')) { continue; }

which should be

                if (srcObj.Class && (srcObj.Class == 'Array') && (typeof srcObj[i] == 'function')) { continue; }
                if (typeof srcObj[i] == 'function') { continue; } // <-- This line is missing

Java Decompiler

For some reasons it is very helpful to have a java decompiler. If you need one, have a look to http://java.decompiler.free.fr/, which also has a good Eclipse integration.

WebCenter Interaction Firefox Add-on

andreas.mersch@gmx.de (andreas mersch) — Mon, 27 Apr 2009 06:22:39 GMT

On August 27th, 2008, Bill Benac published a very useful Firefox Add-on. With this add-on you can always recognize the portal server the response came from. Especially it is very useful in a clustered environment.

My colleagues and me extended this add-on with additional information, like the construction and response time. You can get this add-on from Bill Benac's website http://blog.billbenac.com/blog/2008/08/firefox-plugin-shows-host-port.html or send me a mail ;-).

Oracle WebCenter Interaction 10gR3 (WCI, former BEA Aqualogic User Interaction) User-Friendly-Url Bug ('User-Friendly-Urls don't work in SSO environment') fixed

andreas.mersch@gmx.de (andreas mersch) — Thu, 23 Apr 2009 06:56:08 GMT

While developing an intranet portal based on Oracle WebCenter Interaction 10gR3 for a customer, developers of idesis GmbH (http://www.idesis.de) have successfully fixed a bug with accessing a bookmarked community page (portal page) url when the user doesn't have a valid portal session in a SSO (Single SignOn) environment yet.

There are 4 different ways to open a community page:

http://<portalurl>/portal/server.pt
http://<portalurl>/portal/server.pt?open=514&objID=12345&mode=2
http://<portalurl>/portal/server.pt?uuID={C8DC1486-F0CF-4DD4-A0A8-753E0D6B2D36}&mode=2
http://<portalurl>/portal/server.pt/community/information_management/1111/information_management

The first address always opens the homepage, so it isn't interesting for us in this case. The second address always works, even in a SSO environment. Address-type 3 and 4 only work if the user already logged on the portal.

You can reproduce the bug doing the following steps:

Configure an WCI 10gR3 portal (or ALUI 6.x) with SSO.
Bookmark a community page.
Open a new browser window and attempt directly access that bookmarked community Url.
Note that you are redirected to your My Page / Homepage (it depends on the configuration of your experience definition)
Now that you're already logged in via SSO, if you paste the community URL again into the address bar then you will properly be directed to the community.

Single Sign-On mit ASP.NET 2.0 über zwei Applikationen

Um auf Anmeldeinformationen einer Web Applikation aus einer anderen Web Applikation auf der selben Maschine zugreifen zu können und so eine Art von Single Sign-On abzubilden, ist entscheidend, dass in der web.config beider Applikationen der selbe machineKey konfiguriert wurde.

C# 3.0: Extension Methods

andreas.mersch@gmx.de (andreas mersch) — Wed, 19 Dec 2007 11:42:12 GMT

Mit C# 3.0 ist es möglich, Klassen von außen mit "Extension Methods" zu erweitern, ohne von der entsprechenden Klasse ableiten zu müssen. Dies ist von Vorteil, wenn man den ursprünglichen Datentyp (die ursprüngliche Klasse) beibehalten (Instanz i ist weiterhin vom Typ t), sealed oder Fremd-Klassen erweitern, oder unabhängig bei zukünftigen Weiterentwicklungen sein möchte... Die Erweiterungen werden im Quellcode verwendet, als gehören sie zu der jeweiligen Klasse. Im Visual Studio 2008 werden Extension Methods von IntelliSence durch den Hinweis "(extension)" gekennzeichnet.

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;>

namespace _002_MethodExtensions
{

   public static class MyStringExtension
   {
      public static string Reverse(this string s)
      {
         if (s == null || s.Length == 0)
            return s;

         StringBuilder sb = new StringBuilder();
         for (var i = s.Length; i != 0; --i)
         {
            sb.Append(s[i - 1]);
         }

         return sb.ToString();
      }
   }>

   class Program
   {
      static void Main(string[] args)
      {
         string hello = "Hello World";
         Console.WriteLine("{0} --> {1}", hello, hello.Reverse());
      }

C# 3.0: Automatisch implementierte Eigenschaften

andreas.mersch@gmx.de (andreas mersch) — Tue, 11 Dec 2007 07:54:09 GMT

Ein neues Sprachfeature von C# 3.0 sind automatisch implementierte Eigenschaften. Wo bisher ausimplementierte Getter und Setter notwendig waren, reicht nun die simple Anweisung "get;" bzw. "set;" bei der Property Deklaration.

Beispiel:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace _001_AutoImplProperties
{

   /// <summary>
   /// Sample class for Automatically Implemented Properties
   /// </summary>
   class Person
   {
      public Guid Id { get; private set; } // only public getter
      public string Name { get; set; } // public getter and setter
      public string Address { get; set; }
      public string City { get; set; }
      public string Zip { get; set; }>

      public Person(Guid id)
      {
         Id = id;
      }>

      public override string ToString()
      {
         return string.Format("{0} ({1})", Name, Id);
      }
   }>

   class Program
   {
      static void Main(string[] args)
      {
         Person a = new Person(Guid.NewGuid()) { Name = "Andreas", Address = "Adresse 1", Zip = "12345", City = "Ort 1" };
         Person b = new Person(Guid.NewGuid()) { Name = "Melanie", Address = "Adresse 2", Zip = "98765", City = "Ort 2" };

         Console.WriteLine(a);
         Console.WriteLine(b);
      }
   }
}>

Default Java VM unter Ubuntu umschalten
