This sample provides Java "Hello World" program that is invoked

from C# application in the same process.

The problem of direct call of the JVM API from CLR applications

by PInvoke interface is the JVM API functions do not have static

adresses, they need to be got by JNI_CreateJavaVM() call.

The sample contains C++ libraty that wraps JVM API calls by the

static functions that are called from the C# application by

PInvoke interface.

The sample contains the following files:

Makefile - make file

README.txt - this readme

invoked.java - the invoked HelloWorld Java program

invoker.cs - C# invoker application

jinvoker.cpp - C++ wrapper

jinvokerExp.h - wrapper library exports

After the success making the following files are produced:

invoked.class - the compiled HelloWorld class

invoker.exe - the executable .NET program that invokes Java

jinvoker.dll - the wrapper library

The following environment needs to be set for the correct sample

build and execution:

INCLUDE must contain the paths to:

1. MS Visual C++ standard include

2. .NET SDK include

3. Java includes

Example: %MSDEV%/VC98/Include;%DOTNET%/Include;%JAVA_HOME%/include;%JAVA_HOME%/include/win32

LIB must contain the paths to:

1. MS Visual C++ standard libraries

2. .NET SDK libraries

3. jvm.dll

Example: %MSDEV%/VC98/Lib;%DOTNET%/Lib;%JAVA_HOME%/jre/bin/client

PATH must contain the paths to:

1. MS Visual C++ standard bin

2. MS Dev common bin

3. .NET SDK libraries

4. Java bin

5. jvm.dll

Example: %MSDEV%/VC98/Bin;%MSDEV%/Common/MSDev98/Bin;%DOTNET%/Lib;%JAVA_HOME%/bin;%JAVA_HOME%/jre/bin/client;%PATH%

To run the sample please do:

invoker.exe invoked
