I use MySqlUdfJavaLauncher for not make polling to db, for send notification to an android app when db change this is my config: C:\Program Files (x86)\MySQL\MySQL Server 5.6\lib\plugin




compile with javac -cp "path/to/jar" and add foo.class and json.jar in dir of mysql plugins, when i run select call_java_method('Test', 'myMethod("anString")'); in workbench have this error:

InvocationTargetException: java.lang.reflect.InvocationTargetException, message: null, localized message: null
import org.json.JSONObject;

public class Test {
public static String myMethod(String message) {
int a=1;
int b=2;
int c=a+b;
org.json.JSONObject jsonObj = new org.json.JSONObject("{\"phonetype\":\"N95\",\"cat\":\"WP\"}");

return "successfully invoked myMethod. Message: " + message + c + jsonObj;
