Hello! I need to use an object oriented data repository for a project. It's going to be something between a wiki and a CMS. I'm not an expert in the field of persistence yet. I suppose Hibernate and Jackrabbit are the frameworks to go, right? As far as I'm informed correctly, Jackrabbit does not support annotations or other convenienc...
Overview This is the scenario: I'm given a value which represents a portion of the total number of minutes that exist in a standard week (assuming 10,080 minutes a week and 1,440 minutes a day) starting midnight Saturday (so 0 minutes Sunday @ 12am). I need to convert this minute value into an actual time value (like 8:35am) and I wan...
I would like to create a RESTful app on Google App Engine. I would like to provide XML and JSON services. I have briefly experimented with Restlet, Resteasy, and Jersey. I haven't had much success with any of them, other than some simple examples in Restlet. Could you share your experiences creating a Restful web application on Google A...
Hello, I just installed JBoss and tried to run it from Eclipse. When I first tried to run it I got an error stating that ports 8080 and 1098 are already being bound to something else. I changed those in the config files. Here is example of where I changes port 1098 to 10098 <bean class="org.jboss.services.binding.ServiceBindingMeta...
Hello, I'm writing a toolbar for Firefox using Javascript connected to a Java XPCOM component. I want it to send a receive URLs from an external application that the java end is connected to. I can send the URL just fine, and I can load an incoming URL if I know one is there, but it's missing something crucial. There is no way for the u...
Hi I get this error in windows xp, when try to access http://localhost:8080. I do not see any errors in resin before hand. Also the JAVA_HOME in windows is set. 500 Servlet Exception Resin can't load com.sun.tools.javac.Main. Usually this means that the JDK tools.jar is missing from the classpath, possibly because of using a JRE ins...
This question is for the UISpec4J testing framework, for testing Java GUIs... I'm trying to test an error message pop-up window (modal) that results from making a selection from a ComboBox, but I'm not sure how to return a Trigger object from the select action. Here's a snippet: WindowInterceptor .init(window.getComboBox("ComboBox...
Hello, I'm using JSF/ICEFaces. I have a table that have many rows with values and I have another page that displays charts. I want to have an icon on every row to chart that specific combo. I know to do regular navigation with JSF by returning a string navigation rule. However, I'm not sure how to pass parameters from the bean correspon...
In Java, of course. I'm writing a program and running it under a Windows environment, but I need the output (.csv) to be done in Unix format. Any easy solution? Thanks! ...
If a java client calls a remote EJB on a different server, how can you get the client IP address? Note that it is important to get it from the server, because the client is likely behind a NAT firewall, and in this case we need the public IP address. NOTE: Although it would preferably be a generic solution, at a minimum I could use one ...
When reading online discussions about MVC frameworks, I hear a lot of commentary pointed toward PHP projects like Cake, Code Igniter and Symfony from Java/.NET developers in the vein of "those are clever hacks, but not true MVC". So, what makes something a "true" MVC framework. i.e. what's an example of a .NET or Java MVC framework th...
I just installed Java 1.6 on my OSX and everything works brilliantly, except that Eclipse refuses to start. It puts up a huge prompt from which I can't copy/paste, but it's clearly stating that it wants to be using Java 1.5 and can't find it anymore. I don't see anything in its configuration files about which version of Java it should b...

Hi, I am using eclipse for java programming but lines in the editor look little closer. And I want to change the amount spacing/gap between lines. Is there any option in eclipse that I can use to achieve this effect ? ...
I have a simple method that just does two lines and tries to return all objects in an oracle database table: DetachedCriteria criteria = DetachedCriteria.forClass(Object.class); return (Collection)getHibernateTemplate().findByCriteria(criteria); However, I got an "ORA-01031: insufficient privileges" error. When I checked the logs for ...
As a relative newbie in the Java world, I am finding many things frustratingly obtuse to accomplish that are relatively trivial in many other frameworks. A primary example is a simple solution for asynchronous http requests. Seeing as one doesn't seem to already exist, what is the best approach? Creating my own threads using a blocking t...
I thought this question would have been asked before, but I couldn't find it here... I've used SWIG to create a JNI wrapper around a C++ class. All works great except that Java never seems to call the class's finalize(), so, in turn, my class's destructor never gets called. The class's destructor does some final file I/O, so unfortunate...
For a J2EE bean I am reusing code that was developed for a java swing application. JOptionPane.showMessageDialog() is unfortunately commonly used. Most occurences luckily in code sections that are not reused by the J2EE application, but in some cases lower levels of the code has instances of JOptionPane.showMessageDialog(). Obviously thi...
My question is about the Java for statement, e.g. for (int i = 0; i < 10; ++i) {/* stuff */} What I don't understand is precisely how much code / what kind of code I can put in the parentheses (i.e. where I have int i = 0; i < 10; ++i in my example)- I don't really understand the language used to describe it here: http://java.sun.co...
I'm a fairly experienced Java user, but I've just started trying to use NetBeans to build a GUI. Previously I coded GUIs by hand, but this is a bit of a bigger project. Anyways, I have a Vector in my model (MVC design), and I want to make the list populate with elements in my vector. I know how I'd do this by hand- I'd initiate the li...
