If you develop applications, which consumes web services from other applications or integration platforms, debugging can often be very deflating. If you don't use the correct debugging tools, you don't see the generated SOAP messages which are delivered between the parties.A very useful tool is the Open Source SOAP monitoring tool from predic8. The tool does the same as the TCP monitor from Axis,

As I think, I already mentioned here, I believe, that Cloud Computing (and Software as a Service, but this is a slightly different topic) are true game changers in our understanding of software infrastructure and development/deployment. Currently things are still quite rough around the edges, but I believe, that in like 3-5 years the default option of application deployment will be in one cloud

I recently informed myself about the (Sun) Glassfish J2EE server. I never took it as a serious competitor in the field, as I had the impression it is just a reference implementation that is from Sun... However, I had to change my opinion. In the recent years it seems, that the Glassfish community worked hard on their baby and currently it seems to be a solid competitor in the field.The Glassfish

The architectural style REST has gained some popularity and is often brought up against SOAP for interoperable web services. REST stands for Representational State Transfer and has some characteristics that distinct itself from other architectural styles:Resources such as a person, an order, or a collection of the ten most recent stock quotes are identified by a (not necessary unique)

REST ist an architectural style on how to let distributed applications communicate. It is considered as an alternative approach to XML:RPC or SOAP webservices. I generally like that Google Talks introduction to REST:I would also recommend additional resources to get a more complete picture on REST, check out this link.

The Waterfall RequirementI find this really interesting: In talking with many people who actually do make Software in the last years (not only talk about it *g*) I think I detected that many have a growing problem with the term "requirement". Martin Fowler sums it up greatly in his recent blog post. He makes a strong point in saying that the understanding that many people have about "requirements

Cloud computing is the fashion right now and Google is positioning it's AppEngine against services like Amazon EC2. However similar on the first glance, the two approaches are rather different in detail: Amazon's service is more a virtual server hosting (where you have all freedoms, however are responsible about administration too) plus a set of webservices (like the storage services S3 and

I know, this comes on short-notice, however I myself realized this too late. Next week, to be precise from March 12 to 14 2008 the JSFDays conference will take place in Vienna. There are a set of very interesting speakers like Jürgen Höller speaking about the Springframework and the relation to JSF, there is Martin Marinschek from Irian and myFaces and many others. Keynote speaker is Edward J.

Wicket is a young component based web framework under Apache License, currently available in version 1.3. I've found a good introduction article hosted on TheServerSide , discussing the fundamental concepts behind the framework.Wicket focus on Seperation-Of-Concern by providing the developer a rich component based model to develop components, which are associated with HTML pages. The logic of

In the previous post, Alex gives an overview about Wicket and what advantages and disadvantages this component based framework has. The majority of web applications are very data intensive, where simple CRUD (Create, Read, Update, Delete) operations needed. Apart from this, many software projects use the popular ORM (Object Relational Mapping) Tool Hibernate in association with annotated domain

In the last years, the "market" of Web-frameworks was probably the most active one. I know hardly any other domain, where we can find such a number of different frameworks and tools. There are probable hundreds of different web-frameworks out there; just the Apache Software Foundation has: Struts, Tapestry, Cocoon, Wicket, Turbine (? never knew what this is good for), myFaces. So about 6, if I

Creating (Java, what else *g*) Web-Applications with a new framework is not always an easy task. Where to put which config file, which config options, how to make the build process correctly, how to start the application in the servlet container and how to make an eclipse project and the like. Yesterday (thank you Reinhard) I was pointed to a really great resource:Webtide, the company behind the

Frank Sommers discusses several new attempts in template-engine design and implementations like String Template, the Rails approach, Velocity and the like. Gert Bevin introduces this article in TheServerside.com with the words: "Template engines seem to be one of the most stagnant technologies in Java".Actually this question is quite interesting for me, as I made the same observation over the

In the current Infoweek.ch magazine I published an article about Apache Cocoon. Cocoon is a fascinating XML Framework. However it is a little bit difficult to explain the capacity of Cocoon as it is conceptional quite different from other "Web-Frameworks" like Struts, myFaces, Wicket, Tapestry and whatnot.Hello World...The core concept of Cocoon are XML-processing pipelines: in short, a Pipeline

Ok, I confess, this is probably not a "core" SE topic, however, I was stumbling over Yahoo Pipes today, and I was fascinated. Until now I am not really sure, what I could use this service for and if at all, but yet it looks great.I like it because the idea is fascinating: you can "program" graphically specific data-workflows: Define some input stream (RSS, XML), some preparation, filtering, ...

"Web 2.0" PatternsEven though the term Web 2.0 is not really "brand-new" and also the O'Reilly article is from 2005, I still found it just recently (shame on me), and I still think there might be others out there having not read it.This article tries to define what these "new Web 2.0" applications distinguish from the Web-applications we have seen the years before. The article covers the "Web as

With the rise of object-oriented thinking, frameworks became more popular than never before. A framework is an approach of software reuse and enables developers to establish software systems on an abstract layer. This diploma thesis focuses on the layered architecture where each layer has a predefined task which can be implemented together with a provided framework. This diploma thesis covers the
