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.
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).
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.

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 ?
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.
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.
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?
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!

I need to determine the current state of the Shift key, but at the time I need the state I don't have an InputEvent object around. I need something like java.awt.Toolkit.getLockingKeyState(int) that works for Shift, not just the locking keys like VK_CAPS_LOCK. Is there a way I can do this without listening to input events and storing the for later when I need to check the state?
Thanks!
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.

Hi, implementing service something similar with tinyurl or bit.ly, I'm would like to expose service as API, I'm using java and jersey as RESTfull service implementation.
I'm looking for simplest way for authentification of users who use API, OAuth is first thing coming in mind, but the problem is I don't need this 3 iteration calls with request token query, than access token query with callback url passing. I just need to give user ability to invoke api with no additional security calls to my server.
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.
