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?
Does java have a built-in method to compare precedence of two operators? For example, if I have a char '/' and a char '+' is there a method I can call that compares the two and returns true/false if the first is greater than the second (e.g. true)?
For Example in shell script :
_CLASSPATH =.
for jar in lib/*.jar
do
_CLASSPATH=${_CLASSPATH}:${jar}
done

I'm looking for Java libraries/applications which are parallel and feature objects that can be queried in parallel. That is, there is/are objects in which multiple types of operations can be made from different threads and these will be synchronized.
It would be helpful if someone could ideas of where I could find such applications as well.
EDIT: Actually, language doesn't matter so much, so C++, Python, anything is welcome
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 :)
I have a java application that has an icon in the tray of the menu bar at the top of OSX. I've been able to remove the icon from the dock when the application is "minimized to tray", but it still appears when I command-tab to switch between my running applications. I'd like to hide it from there too, but I'm not sure how to do that, so I would appreciate any advice
Thanks!

As we use "default" keyword as a access specifier, and it can be used in switch statements as well with complete different purpose, So i was curious that is there any other keywords in java which can be used in more then one purposes

JavaMail requires that you specify an external SMTP server when sending mail. I want to have my java app send email directly without having to use an external SMTP server such as postfix or sendmail.
Can anyone recommend a library which provides this kind of functionality?
Ive done some googling and have come up with nothing.
I was surprised to see in the Java source that System.arraycopy is a native method.
Of course the reason is because it's faster. But what native tricks is the code able to employ that make it faster?
Why not just loop over the original array and copy each pointer to the new array - surely this isn't that slow and cumbersome?
Thanks,

The Java Virtual Machine supports several garbage collection strategies.
This article explains them.
Now I am wondering which (automatically selected) strategy my application is using, is there any way to let the JVM(version 1.6) print this information?
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.
Hi!
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).
Thanks for the help
I'm trying to handle an FileNotFoundException in Java by suspending the thread for x seconds and rereading the file. The idea behind this is to edit properties during runtime.
The problem is that the programm simply terminates. Any idea how to realize this solution?

Please help me use/create Concurrent LinkedHashMap.
As per my belief, if I use Collections.synchronizedMap(), I would have to use synchronized blocks for getter/setter.
If I use ConcurrentSkipListMap, is there any way to implement a Comparator to store sequentially.
I would like to use java's built in instead of third party packages.
Thanks

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?
Anyone know of a good library to invoke powershell scripts from within Java? I'm currently spawning a seperate process (powershell.exe) and then parse the output, but it would really be nice if I can leverage Powershell's 'power' by getting objects back from a powershell call.
Edit:
Otherwise, anyone else doing such interop? What method do you use?
