I'm using a native library in my java code which is working perfectly through and through. When I use the same library in grails 3 application, it gets loaded fine, but when I call a native method, it throws UnsatisfiedLinkError exception.
I'm using following code in both cases:
try{
System.loadLibrary("TrippleDes")
String plainText = "passw0rd.!";
String cipher = JniWrapper.encrypt(plainText);
String orgStr = JniWrapper.decrypt(cipher);
System.out.println("Original text: " + plainText);
System.out.println("Cipher text: " + cipher);
System.out.println("Restored text: " + orgStr);
}catch (Exception ex){
System.out.println(ex.getMessage());
}
For simple java code, it works fine with the relevant output. For same code in grails, it throws following exception. I tried to call the native function directly from groovy class as well as wrapping it up in a java class but to no avail. Stacktrace doesn't unveil any substantial debugging probes, but for completeness, here goes:
java.lang.UnsatisfiedLinkError: com.ef.apps.licensing.JniWrapper.encrypt(Ljava/lang/String;)Ljava/lang/String;
