JAsCo.NET

JAsCo.NET is an aspect-oriented extension for the Microsoft .NET platform. Similar to the original JAsCo language for Java Beans, JAsCo.NET introduces two concepts: reusable aspects and expressive connectors. In addition, JAsCo.NET provides support for specifying aspects on specific Web Service interactions. At the implementation level, a new backward compatible, “aspect-enabled” component model is employed, which contains built-in traps that enable to interfere with the normal execution of a web service. The JAsCo.NET component model allows flexible aspect application, adaptation and removal at run-time. This flexibility is valuable and sometimes even required as some web services should stay online as much as possible.

This implementation is a first prototype of JAsCo.NET. Not every JAsCo feature is supported at the moment.

• Microsoft .NET SDK 1.1
• Windows XP. Any other os is not tested at this moment and parts of the program might fail.

1. Unzip JAsCo.NET to <installdir>
2. Browse to <installdir>
3. Add JAsCo.dll to the Global Assembly Cache by executing following command: gacutil /i JAsCo.dll
4. JAsCo.NET is configured

• The test application uses a Web Service. Make sure you are connected to the internet!
• Browse to <installdir>
• Transform WebApplication.exe by executing following command:

 DotNetTransformer /reference:<installdir>\JAsCo.dll /out:<installdir>\TestApp\WebApplicationAdapted.exe  <installdir>\TestApp\WebApplication.exe      

• Compile the EasyAspect.asp aspect by executing following command:

 CompileAspect /reference:<installdir>\JAsCo.dll /out:<installdir>\TestApp\Connectors\EasyAspect.dll <installdir>\TestApp\EasyAspect.asp

• Compile the Upper.con connector by executing following command:

CompileConnector /reference:<installdir>\JAsCo.dll;<installdir>\TestApp\Connectors\EasyAspect.dll /out:<installdir>\TestApp\Connectors\Upper.dll <installdir>\TestApp\Upper.con

• Run the <installdir>\Introspector.exe tool in the <installdir> and open the AdaptedWebApplication.exe to enable or disable the Upper connector.
• Run the <installdir>\TestApp\AdaptedWebApplication.exe. A visual application should pop up. Fortune coockies are displayed in upper or lower case depending whether the Upper connector is enabled or disabled.
