Hi,
I have created a class Test.java in an own package test.lang inside the jdk ("jdk/src/share/classes/test/lang/Test.java"). Now I wanted to add a native method. I found out that my header was created inside" build/linux./jdk/gensrcheaders/testlangTest.h". So I have tried to just create a new file inside a new folder "jdk/src/share/native/test/lang/Test.c" including "testlangTest.h". From there I do my JNICALL to the VM like it is done for example in "jdk/src/share/native/java/lang/System.c". However this still results in a UnsatisfiedLinkError. I am sure I have to do some more steps to link and add it to the build properly. What am I missing? Best regards, Christian
