Preparing for SCDJWS Part 23: Web Services Interoperability

Interoperability is the most important thing when it comes to designing and implementing a heterogeneous distributed SOA system. When it comes to Web Services you should always stick to WS-I Basic Profile, never use proprietary, platform-specific extensions.

The biggest two players on the enterprise-grade distributed systems market: Sun and Microsoft have tested and certified their Web Services frameworks to guarantee the highest interoperability possible.

Section 10 of SCDJWS exam objectives requires you to know the following technologies: Sun's Web Services Interoperability Technology (WSIT) and Microsoft's Windows Communication Foundation (WCF).

Exactly one year ago I was posting some articles about WSIT. In tags cloud please do click wsit tag in order to find all articles and WSIT examples.

Also, it is highly recommend that you read/participate in the following tutorials (first two) and interactive trainings (Sun's Skill Port):

• Sun's WSIT Tutorial
• GlassFish Metro WSIT Documentation
• Courses from https://sunlearningconnection.skillport.com: Working With the Web Services Policy (WMT-SAS-2546), Adding Quality of Service and .NET Interoperability to Web Services (WMT-SAS-1543), Creating Reliable and Secure Interoperable Web Services (WMT-SAS-2544), Creating Transactional Web Services (WMT-SAS-2545)

Testing NTLM secured Web Services using soapUI

I don't believe there is anyone who has ever developed a Web Service and doesn't know what soapUI is.

If not, here' the soapUI home page: http://www.soapui.org/.

Two days ago I tried to test .NET Web Service which was secured by NT authentication.

It turned out that soapUI was able to retrieve the WSDL file (NTLM worked fine), but wasn't able to invoke any Web Service method (suddenly NTLM stopped working).

I found the answer on http://stackoverflow.com.
