Does anyone know what approach one can take to automatically generate Java source code, from for example an xml or json file, in eclipse?
One great example of what I am thinking of doing is what Google Android sdk does: they have an R class generated automatically from the resources.
Every time a resource file is saved in Eclipse R class is automatically regenerated.
Thanks!
Hi,
I need a Java library for doing web searches ( any search engine is good ).
I should be able to to write code such as:
WebSearch search = new WebSearch("Apple");
System.Out.Println("Results = " + search.Results.Count);
Does such a library/API exist ?

This is, I suppose, a very simple question for any Java programmer.
My question is as simple as this:
When the user clicks a button, I want to show a popup form that should have at least two JTextFields and two JLabels, so using JOptionPane.showInputDialog is not a possibility.
Thanks.

I have got a form in Java (Swing) loading large amount of data from the database. I want to display a progress bar while the program gets actually loaded.
How can i do it??
I know use System.exit(0) can end a java program, for instance, if I have a JFrame window, it will close and end the program, but I wonder how many other ways, can it be closed and the program be ended ? Including when an error occurs, will the program be shut down and the JFrame be closed ?
Hello,
I have a test class that has a @Resource annotation for a setter and I need to make it Java 1.4 compliant, so obviously the annotation has to go. I'm using Spring.
So, how would I replace something like @Resource("my.resource") so that the setter gets the correct dependency injection? Would I need to make a bean in an xml file?
I'm pretty new to this so if I'm not providing enough information, let me know.
I need to make a small test program in java which has to communicate with remote Windows server using telnet, or openSSH. Which library would you suggest to use? I'd like to use a well documented and stable library.
Hi all,
I need to create daemon that will monitor certain directory and will process every file that's written to that particular path.
My choice is either java or python.
Did you guys have any experience using both technology? what is the best one?
In .NET you can achieve something like this:
Color yellowColor = Color.FromName("yellow");
Is there a way of doing this in Java without having to resort to reflection?
PS: I am not asking for alternative ways of storing/loading colors. I just want to know wherever it is possible to do this or not.

Hello,
I have a TextArea with enter seperated values:
For Example:
Value1
Value2
Value3
Value4
Value5
Is there a fast way to put them in a String array
String[] newStringArray = ???
In Java is there an equivalent to the C# "using" statement allowing to define a scope for an object:
using (AwesomeClass hooray = new AwesomeClass)
{
// Great code
}
This has probably allready been asked but the keywords make it difficult to find a relevant question.
Why does java.lang.Object have two notify methods - notify and notifyAll? It seems that notifyAll does at least everything notify does, so why not just use notifyAll all the time? If notifyAll is used instead of notify, is the program still correct, and vice versa? What influences the choice between these two methods?
Can you take a subclass object and somehow convert it to an object of the same type as the parent class and at the same time slicing all the fields that are not part of the parent class?
I know you can do this in C++, but I have no idea how to do it in Java.
I have a dll namely product.dll created using .net. How can i access that dll's constructor or method using java code.. Is it possible to access without using JNI?
I use a large (millions) entries hashmap to cache values needed by an algorithm, the key is a combination of two objects as a long. Since it grows continuously (because keys in the map changes, so old ones are not needed anymore) it would be nice to be able to force wiping all the data contained in it and start again during the execution, is there a way to do effectively in Java?
I mean release the associated memory (about 1-1.5gb of hashmap) and restart from the empty hashmap..
I'm trying to run a Java application I wrote to subscribe to a CORBA event service. It runs OK on my Windows machine, but as soon as I deploy it to the UNIX server, it gives me an org.omg.CORBA.NO_IMPLEMENT exception. Any ideas as to why this might be happening? I'm using JacORB on my Windows machine and passing VM arguments to initialize the client ORB, but I'm not sure how to do that on UNIX and if it's even necessary.
Thanks in advance!
hi we are getting out of memory exception for one of our process which is running in unix environmnet . how to identify the bug (we observed that there is very little chance of memory leaks in our java process). so whatelse we need analyse to find the rootcauase
I need to determine the current state of the Shift key, but at the time I need the state I don't have an InputEvent object around. I need something like java.awt.Toolkit.getLockingKeyState(int) that works for Shift, not just the locking keys like VK_CAPS_LOCK. Is there a way I can do this without listening to input events and storing the for later when I need to check the state?
Thanks!
Hi,
I would like to know if you have any good books that teach C++ programming without repeating basic stuff. In fact, I already well know Java and C#. I also have a basic knowledge in C and assembly, so I understand a little bit pointer arithmetic, manual memory management and heap based allocation. I was looking at O'Reilly's C++ in a Nutshell and was also wondering if this book would be a good choice.
Thank you

Does anyone overload the equals method in java? The overloaded method will be
public boolean equals(final MyClass myClass)
This will have the benefit of having the relevant comparison part (guts of the method) in another method.
Details are in this blog.
