Hi there,
I created a program that contains linked lists that are passed various methods. While this works just fine in Java... a style checker program we have to use doesn't like it
It says: Declaring variables, return values or parameters of
type 'LinkedList' is not allowed.
If I declare them as simply List then I don't have access to the methods I want. What should I do?
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
Building shopping cart
Building newsletters system
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!
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.

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).
I use a large (millions) entries hashmap to cache values needed by an algorithm, the key is a combination of two objects as a long. Since it grows continuously (because keys in the map changes, so old ones are not needed anymore) it would be nice to be able to force wiping all the data contained in it and start again during the execution, is there a way to do effectively in Java?
I mean release the associated memory (about 1-1.5gb of hashmap) and restart from the empty hashmap..
I see many similar questions, however I want to find the Username of the currently logged in user using Java.
Its probably something like:
System.getProperty(current.user);
But, I'm not quite sure.
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.
I have one SDK that is available in Java and another SDK that is available for .Net and would like to write a single application that interfaces with both of them. I imagine I will need to use a cross platform communication framework that can support named pipes (or other in memory communication), what is the best choice?
After some more research I found Hessian -- does anyone know anything about the maturity of this project?
I would like to program Java servlets using Eclipse and I plan on deploying them using Tomcat. I think I can build the projects using Ant which is bundled with Eclipse. I have the standard Eclipse IDE. What options do I have for doing Servlet development in Eclipse? What changes do I need to make to Eclipse? Do I need to install a plug-in?
Hi crew,
I'm searching for a tool, which converts a jsp file into a java file without using a server like tomcat or something else.
Can anyone help me out?

In C# you can easily read all classes from a given assembly.
I'm looking for equivalent feature in Java. I need this to automatically bind EJB beans to my Guice Module.

Hi,
After I read Bloch's discussion http://www.infoq.com/news/2010/04/bloch_java_future
I started to think about "Do I have to switch to scala for new web developements" or is java preferred in all cases. What is your opinion ?
Thanks,
Is there a simple way to have your "Service Layer" deployed separately from your web layer, so that I can reduce the number of times per week that I have to, package, build and deploy the entire WAR file?
I'm using Tomcat mostly, but I'm hoping for something more generic to Java web servers
Is it possible to write objects in Java to a binary file? The objects I want to write would be 2 arrays of String objects. The reason I want to do this is to save persistent data. If there is some easier way to do this let me know.
Thanks in advance!
