Hello, I'm trying to find out if it's possible to develop a key capturing application to analyse writing styles when using the SMS composer for the n73 using S60 2nd Edition, Feature Pack 3 SDK in Java? Originally, I thought that all Java applications would be sand-boxed making it difficult to call the native key capture functions avail...
Hullo all, Wondering if there are any Java hackers who can clue me in at to why the following doesn't work: public class Parent { public Parent copy() { Parent aCopy = new Parent(); ... return aCopy; } } public class ChildN extends Parent { ... } public class Driver { public static void main(Stri...
Should Java Objects be reused as often as it can be reused ? Or should we reuse it only when they are "heavyweight", ie have OS resources associated with it ? All old articles on the internet talk about object reuse and object pooling as much as possible, but I have read recent articles that say new Object() is highly optimized now ( 10...
Consider the following example structure - Project - www - files + documents + html + images + scripts - WEB-INF * web.xml The documents folder needs to be a symlink or in some other way external from the war file because users will add and remove documents (throu...
JTextField has a keyTyped event but it seems that at the time it fires the contents of the cell have not yet changed. Because of that .length() is always wrong if read here. There must be a simple way of getting the length as it appears to the user after a key stroke? ...
This problem seems to happen inconsistently. We are using a java applet to download a file from our site, which we store temporarily on the client's machine. Here is the code that we are using to save the file: URL targetUrl = new URL(urlForFile); InputStream content = (InputStream)targetUrl.getContent(); BufferedInputStream buffered...
Given the following Java code for generating a binary file: DataOutputStream out = new DataOutputStream(new FileOutputStream("foo.dat")); out.writeInt(1234); out.writeShort(30000); out.writeFloat(256.384f); I'm using the following Objective-C code and manage to parse the int and the short values: NSString *path = [[NSBundle mainBundl...
Hi, I am a .NET dev learning Java. As a result, I understand all the fundamentals of programming like loops, variables, functions, etc. My biggest bottleneck is that I don't know my way around Java's packages like I do with .NET's. This is the reason for this thread - where do I find the following functionality in Java?: System.Diagno...
I'm almost finished with the book "Head First Java". The reason I'm studying this is I'm hoping to get a job developing with JavaEE someday. Now I'm thinking, should I go ahead and study EE (moving on to Head First Servlets and JSP) or should I spend more time with SE? Would it help? I'll go on and say directly that I want to learn EE in...
My webservice provider give me a large WSDL file, but we are going to use only a few function inside. I believe that the large WSDL have negative impact to the application performance. We use the webservice in client appliction, startup time and memory usage are issues. Large WSDL means that jax-ws will takes longer to do binding and w...
I have been programming in Java since 2004, mostly enterprise and web applications. But I have never used short or byte, other than a toy program just to know how these types work. Even in a for loop of 100 times, we usually go with int. And I don't remember if I have ever came across any code which made use of byte or short, other than ...
Here's the .jsp code: <table> <s:iterator value="allAgents"> <tr> <td><s:property value="firstName" /></td> <td><s:property value="middleName" /></td> <td><s:property value="lastName" /></td> <td><s:checkbox name="ss"/></td> </tr> </s:iterator> </table> When rendered, the checkbox would occupy a whole row bel...
I'm coming from a web-development background and I am wondering how I would make a learning algorithm in Java/C++. Not so much the algorithm part, but making the program "remember" what it learned from the previous day. I would think something like saving a file, but I suspect their might be an easier way. Apologies if this question is j...
Hi all, java -classpath ../classes;../jar;. parserTester How can i get the functionality in the above command programmatically? Like, is it possible to run as: java parserTester and get the same result? I tried using URLClassLoader but it modifies the classpath and does not add to it. Thanx! Thanks for the response Milhous. But tha...
I've been a java developer for a couple years and have heard that you can do some pretty useful and powerful things with JNI. I don't know if I just haven't needed to use it or if it isn't terribly relevant to me; but I have not had to touch it at all. I am wondering what the usefulness of this aspect of Java is. Examples would be grea...

I was reading some Java recently and came across something (an idiom?) new to me: in the program, classes with multiple constructors would also always include a blank constructor. For example: public class Genotype { private boolean bits[]; private int rating; private int length; private Random random; public Genotype() { ...
How can I have that functionality in my game through which the players can change their hairstyle, look, style of clothes, etc., and so whenever they wear a different item of clothing their avatar is updated with it. Should I: Have my designer create all possible combinations of armor, hairstyles, and faces as sprites (this could be a...
