The only different thing is that I had to add 'lib' to the name of the shared library file (I am using Ubuntu 9.10 Karmic Koala): g++ -shared HelloWorld.c -o libHelloWorld.so -I/usr/lib/jvm/default-java/include -I/usr/lib/jvm/default-java/include/linux Thanks, that was very useful!

Here is my command lines used to compile my dll: C:\Program Files\Microsoft Visual Studio 9.0\VC\bin>cl -I"C:\Program Files\Java\include" -I"C:\Program Files\Java\include\win32" -MD -LD HelloWorld.c -FeHelloWorld.dll There will be so many errors as my previous comment although, w/o the command -MD makes all errors disappeared and output as "Hello World!" perfectly after taking the command >java HelloWorld to run everything altogether. BTW, yes you should if you know the detail about these parameters it is used d/r compilation. Because as far as I know -MD option ensures that HelloWorld.dll is linked with the Win32 multithreaded C library. The -LD option instructs the C compiler to generate a DLL instead of a regular Win32 executable. So, I am wondering about such a strange behavior of -MD command now.

But may i suggest looking for an option where you can add parameters during compilation? thanks Hi Neth,

I have been trying to compile exactly the same HelloWorld as I saw from the book here http://java.sun.com/docs/books/jni/html/start.html#769. I follow the step and finally I got the error complaint like: java.lang.ClassLoader.loadLibrary0(Unknown Source) java.lang.ClassLoader.loadLibrary0(Unknown Source) java.lang.Runtime.loadLibrary0(Unknown Source) java.lang.System.loadLibrary(Unknown Source) HelloWorld.(clinit)(HelloWorld.java:7) Anyone knows what is the equivalent command in MS VS c++ as -shared in dev-c++? Please I am really stuck with that for 2 days. Hello there,

I am 3 days new about JNI. I have been trying to compile exactly the same HelloWorld as I saw from the book here http://java.sun.com/docs/books/jni/html/start.html#769. I follow the step and finally I got the error complaint like:

java.lang.ClassLoader.loadLibrary0(Unknown Source)

java.lang.System.loadLibrary(Unknown Source)
HelloWorld.(clinit)(HelloWorld.java:7)

Anyone knows what is the equivalent command in MS VS c++ as -shared in dev-c++? Please I am really stuck with that for 2 days.

As I have the same problem as those errors, I have been searching for the solution but none of them can fix the problem. What is the command in VS c that is equivalent to -shared in g++ that you used? Thanks in advance Hello,
