I have seen that there are many books titled:
Build Ecommerce website in php
Build shopping carts in php or asp.net
Is there any book which explains, from scratch, how to start building a website in Java using any framework or with servlets or JSP?
Desired topics:
Basic forms with logins and registration
Building catalogue system

I need a java program to get the current date without timestamp
Date d = new Date();

But i need only date, without timestamp. I use this date to compare with another date object that does not have timestamp.
on printing
System.out.println("Current Date : " + d)
of d it should print May 11 2010 - 00:00:00 .
Is there a way in Java to find the "Last Fired Time" from a Cron Expression.
E.g. If now = 25-Apr-2010 10pm, cron expression "0 15 10 ? * *" (quartz) should return me 25-Apr-2010 10:15am
I do not care if we use standard cron expressions (like Unix and Quartz) or less popular ones if they can fetch me the correct "Last Fired Time"
I am facing a problem with my singleton when used across multiple class loaders. E.g Singleton accessed by multiple EJBs. Is there any way to create a singleton which has only one instance across all class loader?
I am looking for pure java solution either using custom class loader or some other way.
This question showed up on my mid-term exams and I've been searching for correct answer for some time. I know that Java interfaces can't be directly instantiated so they don't need constructors and that they can have only public static final attributes so they don't need constructors to set them up but that's not the expected answer.
I'm trying to recompile a project I've been working on and I keep getting an error message when trying to load a property file:
The system cannot find the path specified.
I guess this has to do with the classpath. But I've added the path to the file in Properties- Java build path- Libraries (external class).
I also checked the .classpath file generated by eclipse, and the path is really there!
Why isn't Eclipse looking at the right path?
Does anyone know of a tool (besides Eclipse or any other IDE) that I can use to find unused imports in a Java source file?
I am looking for a command-line type of tool (to integrate in a larger script).
Thank you.

Hi,
After some serious googleing I found out that the RandomAccessFile-class is not thread-safe. Now I could use one semaphore to lock all reads and writes but I don't think that performs very well. In theory it should be possible to do multiple reads and one write at a time.
How can I do this in Java? Is it possible at all?
Thanks!

Hi,
I would like to know if its possible to deploy java class files without restarting JBoss server. I am using jboss v4.2.2.

Thanks a lot in advance :)
What's the easiest way to create a simple HTTP server with Java? Are there any libraries in commons to facilitate this? I only need to respond to GET/POST, and I can't use an application server.
What's the easiest way to accomplish this?
Hi there,
is it possible to access a shadowed field of an enclosing class from the enclosed one in Java?
public class Inherit {
public int a = 3;
private int b = 5;

private int d = 8;
public void f() {
System.out.println("Here I want to get a = 3");
...
}
}
}

I haven't found many ways to increase the performance of a Java application that does intensive XML processing other than to leverage hardware such as Tarari or Datapower. Does anyone know of any open source ways to accelerate XML parsing?
What is the best procedure for storing and retrieving, using native Java serialization, generic objects like ArrayList<String>?
Edit: To clarify. When I serialize an object of type ArrayList<String> I'd like to de-serialize to the same type of object. However, I know of no way to cast back to this generic object without causing warnings.

Any tips or best practices for unit testing Google Wave robots written in Java? I'm expecting to deploy on AppEngine, if that helps. I'm a fan of TDD but new to both Wave Robots and AppEngine, so I'm hoping to use TDD to help me explore the design space.
