If WebSphere is running on Rasberry Pi, why not Domino?

with 2 comments

Today, I read an article in > Simon Maple’s blog. He is a software developer at IBM and has installed an IBM WebSphere Application Server on > Rasberry Pi, which is an > ARM GNU/Linux box for only $25. It sounds very interesting and since an IBM Domino server has less system requirements it could be running on a Rasberry Pi in the future, too?

Artikel zu XPages in Java Aktuell erschienen

leave a comment »

In der aktuellen Ausgabe der Zeitschrift > Java Aktuell – Das iJUG Magazin ist ein Artikel über XPages mit dem Titel “XPages – Ein neues Framework zur Entwicklung von Webanwendungen” von mir erschienen. Der Artikel ist als Einstiegsartikel zum Thema XPages für Java Entwickler gedacht. Ein kurzer Auszug:

Mit XPages lassen sich leistungsfähige Webanwendungen entwickeln. Eine XPage basiert auf XSP, einem XML-Dialekt, welches bei der Ausführung in Java-Code umgewandelt wird. XPages sind auf einem IBM Lotus Domino Server lauffähig und können von jedem Webbrowser und dem auf Eclipse RCP-basierten IBM Lotus Notes Client ausgeführt werden. Die Entwicklung von XPages erfolgt mit dem IBM Lotus Domino Designer, einem kostenlos erhältlichen, auf Eclipse IDE-basierten Entwicklungswerkzeug. Objekte lassen sich hiermit per Drag & Drop auf eine XPage platzieren und mit Java oder JavaScript erweitern.

Der vollständige Artikel ist über diesen Link verfügbar: XPages – Ein neues Framework zur Entwicklung von Webanwendungen (> iJUG)

Since some days the new release of > PAVONE Project Management 10 is available. It is a software to create, plan and monitoring projects. It has an user interface for Lotus Notes clients and web browsers. An essential tool is the grafical applet to create and plan projects, which contains a multi-histogram for cross-project capacity management. Further the Eclipse RCP-based client (PAVONE ProjectBuilder) to define project structure plans. The following two videos explain the usage of the gantt applet and the ProjectBuilder.

Reisebericht: Aus der Traum…

leave a comment »

Gestern war ich in > Wolfsburg zum Spiel der > deutschen Frauen-Fußball-Nationalmannschaft gegen Japan. Es war das Viertelfinale bei der Weltmeisterschaft 2011 und die deutsche Mannschaft (Titelverteidiger und zweimailiger Weltmeister) war natürlich der Favorit. Die Stimmung im Stadion war auch gut gewesen. Als das 0:1 fiel war es dagegen sofort still. Leider hat es für Deutschland nicht mehr zum Sieg gereicht. Das > Stadion in Wolfsburg ist aber sehr schön. Die Parkplätze sind sehr nah am Stadion, das Stadion liegt direkt neben dem Mittellandkanal und in die Stadt sind es auch nur knapp zwei Kilometer. Nur die Sitzplätze lassen für die Beine recht wenig Platz. Da hat man z. B. in Hamburg mehr Freiraum.

New Phone

leave a comment »

Last week I bought a new telephone since my old telephone was broken. I decided to buy the > Swissvoice ePure phone in white. It has a nice design and the eco mode means that it produces no radiation if the receiver is hang up. It has not so many features as other cordless phones, but I do not need more features.

Travel Report: London

leave a comment »

Last week I was from Thursday, 26th May until Sunday, 29th May in London. Reason for the trip was the UEFA Champions Leaque final match in London. Unfortunately, we got no tickets. We had no luck in the ticket lottery and the tickets on the market were too expensive (up 1.000 pound). But on Thursday evening we were in Fulham and watched the > Women’s final match between Lyon and Potsdam. Lyon was better and has won 2:0. Although the tickets cost only 5 pound, the match was not sold out. Only 15.000 people were in the stadium. Before the match the weather was very bad, thunder storm, hail and rain. Our hotel was the > Hotel Americana in the Glouchester Place near the Baker Street underground station. On Friday evening we were in the Theater Royal Drury Lane and watched the Shrek musical. In the evening we were in a pub near Oxford street and watched the > final match Manchester United againt FC Barcelona. Barcelona has won 3:1. The flights were operated by > easyJet from > Duesseldorf Airport to > London Gatwick. From London Gatwick I used the > Gatwick Express, which was expensive but fast.

Travel Report: Santorini

leave a comment »

In the second May week I was on > Santorini. It is a Greece island of the > Cyclades. Our hotel was > Scirocco in Fira, the capital of Santorini. If you plan to visit Santorini I can recommend the Scirocco hotel. It is very nice with a beautiful view over the Caldera. Every day you can see some cruise liner. Further, I can recommend the restaurant > Kapari in Fira which was very good. On Wednesday we rent a car and drove over the island. We visited the > Winery & Wine museum. Our flights were operated by > Condor and we flight directly from > Duesseldorf Airport to > Thira Airport. Since the Condor machine was defect we flight with > XL Airways back to Duesseldorf.

Powerful Java API of a Process Engine

leave a comment »

Yesterday, I attend a presentation about the Open Source > Activity BPM platform. A part of it is the Process Engine which has a Java-based API. You can find a > short tutorial about the API on the Activiti website. Of course, other available Process Engine have an API, too. For example > PAVONE Espresso Workflow, which is the core component of > PAVONElive, has a powerful Java API. This code snippet shows you how easy you can import a process definition, create a new process instance based on the process definition and complete the first task of the process.

// STEP 1: Import the process definition
// Imports the file LoanApplication.xml in the directory “c:\ProcessDefinitions”.
WfProcessDefinition wfDef = Session.importXMLProcessDefinition(“c:\\LoanApplication.xml”, “”);

// STEP 3: Initiate a process
// This step initiates a process based on the process definition called ‘Loan Application’
WfProcess process = pcsSession.initiateWfProcess( “”, “Loan Application” , “”, “”);

// STEP 4: Get the first task “Start Loan Application”
// First get all tasks which are in progress and then get the first task of this set.
Set tasks = process.getTasks ( TaskStatus.IN_PROGRESS );
Iterator iterator = tasks.iterator();
WfTask task = (WfTask)iterator.next();

// Place some operations on the task here
// … Your code …

// STEP 5: Complete the first task “Start Loan Application”
boolean success = task.complete();
if ( success == false ) {
// not successful, add error handling
return;
}

Further, you have access to several other features and all the data which will be handled by the engine.
