The executeBatch method is available on the org.jboss.resource.adapter.jdbc.WrappedStatement which is a superclass of org.jboss.resource.adapter.jdbc.WrappedPreparedStatement. Your are calling getDeclaredMethod("executeBatch",null) on WrappedPreparedStatement and hence getting the NoSuchMethodException. The getDeclaredMethod method does not look for the method in the superclass(es). Instead use getMethod:

Method m = ps.getClass().getMethod(methodName, parameters);

See the javadoc of these methods to understand their difference http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Class.html
