We are using "Bottom Up" approach for building webservices.
We have 10 java classes which we want to expose as a webservice.

Does anyone know of any tool that can facilitate/ease porting of an app to both Java Swing and GWT?
I've got a few "screens" that makes complete sense to have both in a desktop app and in a browser and I was wondering if there was some kind of common API that could be targetted that would facilitate creating these two different "views" (see my comment)?
I have to develop a specialised report editor in Java. The user will get a number of fields that can be layed out on a page plus some graphical elements. The resulting report design needs to be serialized into already defined database tables.
Is there any software library that will help to achieve this without reinventing the wheel? I have come across Eclipse GEF and Zest, but I am not sure if this really meets my problem.
At the moment I execute a native process using the following:
java.lang.Process process = Runtime.getRuntime().exec(command);
int returnCode = process.waitFor();
Suppose instead of waiting for the program to return I wish to terminate if a certain amount of time has elapsed. How do I do this?
I am trying to use groovy to do shell scripting on unix, but I am not having any luck having one process retain the environment variables changed by another process. For example,
def p1 = ["bash", "-c", "source /some/setEnv.sh"].execute()
Now, I would like a second process, p2, to inherit the environment variables that was set in p1. How can I do this? I don't see anything in java.lang.Process or its groovy extension that would spit out the environment variables after the process has executed.
In Java, what's generally the most accepted way to organize a class in terms of the order in which declared data members and methods should be listed in the class file, keeping in mind the following and anything else you can think of for each one:
its visibility
whether it's a constructor, method, or member
if it's a method, does it overload, or override other method(s)?
I am running Xcode 3.2.2 with the iPhone SDK and was wondering if there was any way to (re)enable Java templates from the earlier versions of Xcode.
Thanks in advance!
What are the Java language and standard library design flaws you are aware of? I ask only for flaws that:
cannot be changed or are unlikely to change due to backward compatibility,
are NOT controversial, i.e. most of programmers would agree that "this is a bug not a feature" (for example checked exceptions seem to be controversial language feature, so I wouldn't classify them as "design flaw").
Hi all, I would like to know simple k-means algorithm in java. I want to use k-means only for grouping one dimensional array not multi.

group 1: 2,4,5
group 2: 7,12
group 3: 18,25
group 4: 34

I was just wondering how most people fetch a mime type from a file in Java? So far I've tried two utils: JMimeMagic & Mime-Util. The first gave me memory exceptions, the second doesn't close its streams off properly. I was just wondering if anyone else had a method/library that they used and worked correctly?

Thanks
