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?

We can resrict the creation of object of a class by making it's constructor private.
But this constructor could still be called from within the class.
is there anyway to prevent this in Java?
Thnx.

So i'm writing a WebService in Java that should receive a file as an input, and then the WebService does some processing on that file, and finally it should send a new file to the client.
My question is :
How do I send a file to the client? (and how can I tell them to upload one).

A simple question: what is the more efficient way to access a db in Java/JDBC?
I'm a web developper and I'd like to write some reusable and scalable code.
What can you suggest?
In VB.NET there is the WITH command that lets you omit an object name and only access the methods and properties needed. For example:
With foo
.bar()
.reset(true)
myVar = .getName()
End With
Is there any such syntax within Java?
Thanks!
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 :)
Hello,

I am looking for a open source library in Java for HTML Microsoft Word conversion. I have found many tools for Word to HTML conversion but not too many for converse.
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");

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 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 ?
There was an earlier thread on Java graph or chart library, where JFreeChart was found to be quite good, but, as stated in its FAQ, it's not meant for real-time rendering.
Can anyone recommend a comparable library that supports real-time rendering? Just some basic xy-rendering - for instance, getting a voltage signal from data acquisition system and plotting it as it comes (time on x-axis, voltage on y-axis).
