Experience in integrating Java with C# and .NET

Abstract

SUMMARYJava programmers cannot but be aware of the advent of C#, the .NET network environment, and a host of new supporting technologies, such as web services. Before taking the big step of moving all development to a new environment, programmers will want to know what are the advantages of C# as a language over Java, and whether the new and interesting features of C# and .NET can be incorporated into existing Java software. This paper surveys the advantages of C# and then presents and evaluates experience with connecting it to Java in a variety of ways. The first way provides evidence that Java can be linked to C# at the native code level, albeit through C++ wrappers. The second is a means for retaining the useful applet feature of Java in the serverside architecture of web services written in C#. The third is by providing a common XML-based class for the development of GUIs, which can be incorporated into Java or C#. An added advantage of this system, called Views, is that it can run independently of the resource-intensive development environment that would otherwise be needed for using C#. A major advantage of the methods described in this paper is that in all cases the Java program is not affected by the fact that it is interfacing with C#. The paper concludes that there are many common shared technologies that bring Java and C# close together, and that innovative ways of using others can open up opportunities not hitherto imagined.

“…Though Java VM can use native codes with JNI, it cannot use managed codes. However, if the managed codes are wrapped with the native codes, it is able to use them with JNI [9,10]. Figure 7 (in right) shows the relation between the JNI and C#.…”
