java design object-oriented refactoring
I am working on a UI code where I have an Action class, something like this -public class MyAction extends Action {public MyAction() {setText(“My Action Text”);setToolTip(“My Action Tool tip”);setImage(“Some Image”);}}When this Action class was created it was pretty much assumed that the Action class won’t be customizable (in a sense – its text, tooltip or image will be not be changed anywhere in the code). Of late, now we are in need of changing the action text at some location in code. So I su

java jvm stackoverflow
I used to think that it’s not, but yesterday I had to do it. It’s an application that uses Akka (an actor system implementation for the JVM) to process asynchronous jobs. One of the actors performs some PDF manipulation, and because the library is buggy, it dies with a StackOverflowError every now and then.The second aspect is that Akka is configured to shutdown its whole actor system if any JVM fatal error (e.g. StackOverflowError) is caught.The third aspect is that this actor system is embedde

I’m trying to create a Java program that uses some methods from a mathematica package I’ve defined. When I run my java program though the output of the program acts as though the Mathematica methods were never defined. I believe my problem has to do with the way that i’m trying to include the Mathematica package in my java code.Here is the mathematica package (saved as test.m)BeginPackage[“test`”]test::usage = “My test package.” myAdd::usage = “adds 2 numbers” myPrint::usage = “prints ‘print thi

I’m trying to write a Java program that uses Mathematica code, but when I compile it, a window appears asking for MathLink.

I´m new to GIS development. I have read about Openlayers, maps servers (i choose Geoserver), geodatabase (in my case i choose PostGis) and theory of gis in general. I´m developing a Java EE application that needs GIS functionality, but i´m having some problems defining the high level arquitecture for my requirements. Before i explain what alternatives i´m considering, i think it´s best if i give the main requirements that the present application must fulfill:It has to show a map on the browser,

I have found similar questions on StackOverflow, but not quite the same as mine:I’ve configured a Spring bean ‘ontologyClient’ that is a POJO that I have imported from a library which is added to my Maven dependencies. I have checked and double checked that the produced WAR file contains the org.erasmusmc.ontology.OntologyClient class. However, when Spring wants to instantiate the bean, Tomcat’s classloader throws a ClassNotFoundException. I am out of ideas, hopefully somebody can help me out!ap

Nonetheless, I tried downloading and using the JPA container and the BeanValidator and I can’t get it working. Here is the code I am using:package com.example.firstvaadin;import java.io.Ser
