  Thank you very much for the solution. I followed your instruction and every thing is fine except the file jni4net.j-0.8.6.0.jar I could not find it in the downloaded library. could you please show me how to get the jar file.

  Trying jni4net to gain access to methods and classes in existing JAR. The object gets the correct path, but the only file listed when the command findJAR is the jni4net.jar. What am I doing wrong? what procedure needs to be followed to get other JAR files to load properly?

  Note that unmanaged languages and compliers support mixing languages in a single executable but .Net does not. For example we cannot combine C# and VB.Net in one executable. Therefore the absence of support for mixing C# and Java in a single executable is consistent with the design of .Net. I have written many programs back in the day (before Windows) when the operating systems did not support dynamic linking. I agree it would be good to be able to mix languages in a single executable but Dynamic Link Libraries seem to not be a performance problem and use of separate files for multiple languages seem to be good for most things. So if it is possible to call Java in a separate file from C# then it seems to be a good solution most of the time at least.

  I mean why we need to leverage Java in c#

    It depends on circumstance, sometime we need to run some essential code in C# which is already pr-written in java language. then such tactics could be useful

    In our Environment we have Java Connectors to Legacy Older Oracle Technology. We are also reverse engineering engineering a c# .net WPF Application that needs to read data from this legacy Older Oracle Database. But this is not possible since no Oracle Connectors can be found for c# but is available for java. Also on the particular server it is not possible to run a Java Web Service because the container like Glassfish Application is not allowed to run as a windows service. So we have to work with either a csv file created with java then read the csv file in c#. Or use jni4net. I did not find any documentation on invoking 3d party java code so I think I should use reflection java code in the c# code.
