call java methods with argumenrs in JNI

Question

I am working on JNI program and I am not able to call a java method from my C++ program.

The code snippet of java method is here

public static void getTables(Connection conn) throws Exception {

    String TABLE_NAME = "TABLE_NAME";
    String TABLE_SCHEMA = "TABLE_SCHEM";
    String[] TABLE_TYPES = {"TABLE"};
    DatabaseMetaData dbmd = conn.getMetaData();

    ResultSet tables = dbmd.getTables(null, null, null, TABLE_TYPES);
    while (tables.next()) {
      System.out.println(tables.getString(TABLE_NAME));
          System.out.println(tables.getString(TABLE_SCHEMA));
    }
  }

And I want to call this java method from C++ program.

I am able to call the main method for that the code is

midMain       = env->GetStaticMethodID(clsH, "main", "([Ljava/lang/String;)V");

I want to call getTables method like this. Please help me to solve it.

Are you having trouble with getting the method id, creating the Connection parameter or calling the method? Show that code. — Tom Blodget, Jul 03 '14 at 17:47

Please see https://stackoverflow.com/a/14872927/755804 and probably these: https://stackoverflow.com/a/14021142/755804 https://stackoverflow.com/a/15941319/755804 https://stackoverflow.com/a/21109940/755804

There is some difference between calling static and non-static methods, but not much. I suggest you start with something that works and gradually change it to what you want.
