Hi,
I've used JAXB Marshaller as well as my own marshaller for marshalling pure java bean objects into XML. It has been observed that both of them require almost same time to marshal. The performance is not acceptable and needs to be improved. What are possible ways where we can improve performance of marshaller? Like threading?
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.
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!
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 ?
Hi All,
I have a small application in java which searches images using bing image search. The problem I am facing is that, its getting only first 20 images. May be because when we search on bing.com it populates first 20 images first and then its an infinite scrolling feature.
Is there any way to search more than 20 images using bing?
Cheers :)
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 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.
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.
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'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 there,
I have a Java IRC bot which i would like to query a shoutcast server and return basic information (song playing etc). Can someone guide me in the right direction? Thank you.
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,
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

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 .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.
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?
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.
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..
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
