JVM invocation with JDK1.4 using JNI

[Uri]

Hi,

I am trying to run the code from:
http://www.codeguru.com/Cpp/misc/misc/interfacingtootherlanguages/article.php/c405/
With JDK1.4 but it fails in the method: "JNI_CreateJavaVM". (return
value -1)
I can't find the reason for that. Any help will be very useful for me.

Thanks,
Uri.

The example uses the 1.1 version of the JNI argument struct, which
changed in 1.2.

http://java.sun.com/j2se/1.4.2/docs/guide/jni/jni-12.html#JNI_CreateJavaVM

Note that when you use the newer struct (described in the JNI
documentation), you don't need to call JNI_GetDefaultJavaVMInitArgs(),
and you should use the symbolic values for the version identifier
(e.g. JNI_VERSION_1_4).

Also make sure that you compiled your application with support for
multiple threads, and that the shared libraries belonging to the JVM
itself can be bound by the application at runtime. Exactly how you do
these things depends on your platform and your compiler.
