I have had 2 courses in Java programming. We only used a pico editor on a sun server. I am transferring schools but they asked me to cover several chapters on Java graphics before my Advanced Java classes this fall. What options do I have for free or cheep IDEs to use for Java graphics? ...
I'm trying to add a referer to an http post in Apache HttpClient (httpclient-4.0-beta2). I found some sample code that does this. The code works, but I'm wondering if there is not a simpler, more straightforward way to add the referer than using the (ominously named) addRequestInterceptor, which appears to take an (yikes!) inner class a...
I have the following JUnit test: @Test public void testRunLocalhost() throws IOException, InterruptedException { // Start an AnnouncerThread final AnnouncerThread announcer = new AnnouncerThread(); announcer.start(); // Create the socket and listen on the right port. final DatagramSocket socket = new DatagramSocket(...

I have application written in GWT and hosted on Google AppEngine/Java. In this application user will have an option to upload video/audio/text file to the server. Those files could be big, up to 1gb or so and because GAE/J does not support large file I have to use another server to store those files. This would be easy to implement if th...
I'm solving Uva's 3n+1 problem and I don't get why the judge is rejecting my answer. The time limit hasn't been exceeded and the all test cases I've tried have run correctly so far. import java.io.*; public class NewClass{ /** * @param args the command line arguments */ public static void main(String[] args) th...
I've too many methods that repeatedly do something like Statement stmt = null; ResultSet rstmt = null; try { stmt = conn.createStatement(); rstmt = stmt.executeQuery(...); while (rstmt.next()) { //handle rows } } catch (SQLException e) { //handle errors } finally { try {rstmt.close();} catch (SQLException...
Often I will send debugging info to my log file from within Java, and it helps to give decent information as to where in the code the log message was generated so I can quickly refer back to it. I don't want to hard-code anything in the log message about its location, because I have to remember to update the log message if I rename its ...

I have an application (let's call it "APP") and i have a "PerformanceStatistics" MBean written for APP. I also have a Singleton Data class (let's call it "SDATA") which provides some data for th...
I have the following test case in eclipse, using JUnit 4 which is refusing to pass. What could be wrong? @Test(expected = IllegalArgumentException.class) public void testIAE() { throw new IllegalArgumentException(); } This exact testcase came about when trying to test my own code with the expected tag didn't work. I wanted to see ...
I'm using dom4j to parse my xml. Let's say I have something like this: <?xml version="1.0" encoding="UTF-8"?> <foo> <bar>ƒ</bar> </foo> When looking at the value of the "bar" node, it gives me back the special character as represented by "& #402;" Is there a way to prevent this and just read in the actual bit of text? ...
Greetings, Just a bit of backgroung information - I am currently working on a relatively large desktop-based requirements management utility, and have come across an issue for which I believe I know the solution, but am hesitant to implement without further thought. Basically, at anytime during the usage of this requirements management...
For the past few years I've continuously struggled with unit testing database code and all the pain that comes with it. I found this existing thread which I found very enlightening: What's the best strategy for unit testing databases? The author of the accepted answer suggests that it might be useful to mock the entire database layer...
I am writing a java based chat server and currently my design is based on following :- when a person in a chat room sends a message, the chatroom class at the server side, sends the same message to every participant in the room in a loop. Obviously , this is a poor design because networks calls are being made to individual participants i...

I have a pipeline-based application that analyzes text in different languages (say, english and chinese). My goal is to have a system that can work on both languages, in a transparent way. NOTE: This question is long because it has many simple code snippets. The pipeline is composed of three components (lets call them A, B, and C), and ...
One of the most frequent thing I do with Eclipse is to re-run the last program. I do it by going to Run -> Run History -> [top most item]. Is there a shortcut key that does this? Edit: I know of CTRL+F11 but this does not work for me. It will launch the most recent program only if the currently active class (the class whose source code...

When I do a job search for a .Net developer it's all mostly the same stuff .Net, ASP, SQL Server, CSS, Javascript, AJAX, and maybe C#. Whereas with Java you may have to have Java, Sturts, Spring, JSF, EJB, a RDMB, Eclipse RCP, CSS, Javascript, AJAX, Rest, any number of specific Java APIs. Is it easier to be a .Net developer since the tec...
