Is it possible to link a static library to Java through JNI?

Question

Is it possible to build a HelloWorld.lib and load it to a Java application using JNI? Or it just works with shared libraries?

I couldn't find a clear answer on the JNI documentation, there's no reference to "static library".

Answer 1

It needs to be a dynamic library. Fortunately, you can build a dynamic library from a static one.

Answer 2

Java 8支持静态链接的本机库http://openjdk.java.net/jeps/178

Answer 3

To load a library at runtime it must be a dll (windows). If you have a static library (lib) and you have to use it via JNI you have to create a wrapper dll

Answer 4

You would have to link it to the JVM, and you don't have a way to do that. That's why JNI is defined with shared libraries, not static ones.
