Can JAVA call the .so file on linux platform?

There are two ways to do this:

• JNI allows you to declare methods as native in Java, and implement then in some other language (typically C or C++) and provide them as ".so" files. However, you can't do this for any old ".so" file, because Java expects the methods in the ".so" to have JNI specific signatures.

• JNA allows you to call methods in arbitrary native libraries. You write Java code that provides a "native library declaration" to match the native methods' signatures, and the JNA infrastructure deals with the data type mapping, etc.

Yes, via JNI.
