As I wrote before it is quite easy to set up a web service proxy with Mule3. in this example I take it a step further and I describe how you can add WS-Security implementation to it. Although in the end this also is quite easy you have to make the correct configuration choices to get everything to work.

The first thing I had to do in my Mule config was to drop the pattern prefix. This took me a while to discover because I think this isn’t very clear in the documentation. Anyway, after that change it is fairly straight forward.

In this post I show you how I setup a little test to see if and how easy I could manage to route the traffic to and from a web service through Mule ESB. The business case for this is an issue that one of our customers ran into when using web services. In a program hundreds of calls are done in a relative short period. Most of the time this isn’t a problem but sometimes vague issues occur. To get a better insight in this issue I want to put Mule in the middle so I can log the request and response and hopefully get a better idea about what is sent across the line. This is called the Web Service Proxy pattern and is commonly used to validate and audit the web service calls. For more background info about this pattern see this article.

Some time ago I was asked to review existing web services for a customer. The main thing I noticed was that they were using Microsoft’s diffgram elements and attributes in their input and output messages. I was not familiar with this format but found out that it has been created by Microsoft to make synchronizing datasets in .Net easier. In this case the web services were implemented with Spring-WS, so there was no real reason to use this format on the server side. Besides, it only makes the web service less useful on the client side since it leads to complications if you want to use a XML-Object mapper like JAXB (see this for example). One of the issues with Diffgram is that, besides the XML containing the Diffgram element, also the XSD is included. This XSD describes the content of the Diffram Dataset, however, the XSD and the resulting Dataset do not match because extra attributes are added (this is described in more detail here). (more…)

From time to time I am evaluating a tool or framework for which I need a web service. Although there are examples of running serviuces available on the web, I don´t always have access to the web and sometimes you need some more control over the service so you can edit/influence the corresponding WSDL. For these cases I created the following class which is all you need to get a web service running on your local machine (assuming you have JDK1.6 installed). (more…)

In my current project we are going to need a BPEL engine besides our Mule CE implementation. Actually, we will use Mule for our stateless communication between systems and use BPEL for the stateful processes. One of the possible frameworks to use as a BPEL engine is Apache ODE. In this post I will show you how you can start a BPEL process in Apache ODE with Mule. As you will see, it is merely a combination of posts I made earlier, but I think it is nice to have the complete thing in one post.

Although it has been a while since I posted about SoapUI I am still receiving questions about the tool. The most frequently asked question is how to solve the error ‘Error import WSDL’ so I will post the steps I took in the past to solve this error, hoping that this might help you. The first step I usually take is to try to open the WSDL in a web browser. (more…)

This post is one of the series of posts about issues that occurred when we were using Mule2 in a real life project. As I wrote in my last post we were using CXF to call a webservice with Mule. After the issues we ran into as described in that article, we ended up with the folowing issue. The generated classes that are used for the XML to Java mapping has to be serializable. This is possible by using a binding file when generating the classes with Maven as described in the documentation here.
However, I haven’t been able to do this in my situation. And according to this post I am not the only one. So to keep the project moving I decided to make use of Metro JAX-WS instead of CXF, since this CXF thing had cost us enough of our precious time. With the Metro implementation we had it running in no time without any unexpected issues.

As I described here I am using JAXWS’ wsimport function to generate a Webservice interface and the JAXB objects for my application. The generated JAXB objects are also used as parameters for some remote EJB calls. Therefore I had to make the JAXB objects serializable. But the question is how to do this since these classes are generated.
Well, in these situations Google is your friend. (more…)

As might be clear by my latest posts I am currently working on a project where we use Glassfish and EJB3 as platform for our JEE application. One thing that we had to decide upon was the WebService framework we were going to use. There are quite some options available but I decided to have a look at Metro, the JAX-WS reference implementation. Also due to the fact that it is integrated with EJB3 and Glassfish.
To create my ‘HelloWorld’ service with Metro and Maven2 I used this post as a guideline. I am also going to work top-down (WSDL -> Java approach) so I will be starting with an existing WSDL and then generate/create the web service interface for that. Although the post I used as a guideline is very detailed I ran into some issues, mostly the result of using different versions of dependencies and plugins. In this post I show the steps I made to get it working. I am using Glassfish-v2ur2 (comes with Netbeans 6.5) , JDK1.5 and Maven 2.0.9.

A year ago I posted how you could create a EJB3 webservice and deploy it on JBoss with Maven. Currently I am doing a similar thing at my project, but this time I deploy it to Glassfish. The creation of the web serive is similar but for the deployment you will need another plugin (if you want Maven to deploy the webservice, of course). (more…)
