  • What is the best way to modify a few fields in an XML using Java

    - by Kailas J C
    I have a big XML which contains around 300 elements. I need to modify 2 or 3 elements in this xml using Java. I don't want to go for conventional marshalling and unmarshalling as it involves the parsing of the whole XML. How is XPath/XSLT manipulation? I know that I can easily read the data but i need to modify the same and put in back in the same XML. The primary concern here is performance. Kindly advise

  • Java Compare Addresses

    - by Tom
    Hi, Does anyone know a library to compare addresses in Java ? Something that would give equality on addresses, written in different ways. For example, it should recognize that "22 Acacia Avenue" and "22 acacia av." is the same address. Of course, this can escalate a lot, that's why i'm asking. Thanks in advance.

    - by TwentyMiles
    Java's jar file format builds off of the zip file format, and supports compression of the class files inside it. When and how does the JVM decide which class files to uncompress and pull out of the jars on its classpath? Is the process dynamic and done at runtime as classes are needed, or are they all uncompressed up front before the program actually runs?

  • Java: Check if file is already open

    - by hello_world_infinity
    I need to write a custom batch File renamer. I've got the bulk of it done except I can't figure out how to check if a file is already open. I'm just using the java.io.File package and there is a canWrite() method but that doesn't seem to test if the file is in use by another program. Any ideas on how I can make this work?

    - by user65374
    From what time I've spent with threads in Java, I've found these two ways to write threads. public class ThreadA implements Runnable { public void run() { //Code } } //with a "new Thread(threadA).start()" call public class ThreadB extends Thread { public ThreadB() { super("ThreadB"); } public void run() { //Code } } //with a "threadB.start()" call Is there any significant difference in these two blocks of code?

  • Simple Java AMPQ server

    - by splix
    Are there exists an simple AMPQ server/broker implementation written in Java? I need it only for local integration tests, starting it from ant/maven, and i don't need any features like a clustering, persistence, performance and so on. Just a fake RabbitMQ-like instance, without installation (just as a dependency at maven pom) and configuration.
