The team in which I work has been getting problems with the visual inheritance of the forms in the Java platform. We want to develop a base JFrame with some controls in it and to have inherited forms from that base JFrame. The designer of the Netbeans 6.1 does not paint the controls of the base form in the inherited ones, so we can´t us...
Are there any tools that auto-generate the hibernate POJOs by gathering information from the database? I made a perl script to do this after the schema got changed for the third or fourth time in a project i'm working with and just wondered if there is any established tool that will do this for me as my script is rather crude and needs ...
Hi, Until recently we used Oracle sequences to generate the IDs of a table. This is now changed, a new ID is now calculated by an Oracle function. Which means that my application needs a change to adept to the new situation. The application is a Spring/Hibernate webApp, which access the Oracle database. This was configured in an hbm.xml...
We have a Java-application that needs to be brought to the foreground when a telecontrol mechanism activates something in the application.

The method is static, but I cannot find mention of if it is thread-safe or not. I plan on hitting this method with several threads at once and I would like to avoid a synchronized block if possible. javax.mail.Transport.send(msg); ...
I used a new Date() object to fill a field in a MySQL DB, but the actual value stored in that field is in my local timezone. How can I configure MySQL to store it in the UTC/GMT timezone? I think, configuring the connection string will help but I don't know how. There are many properties in the connection string like useTimezone, serve...

I've used JSmoothGen in the past, but recently we've seen a number of machines that refuse to run the .exes that it generates. It also seems not to be actively maintained so heavily any more. Are there any alternatives that are more actively maintained and more reliable? ...
I come from a background of MoM. I think I understand ESB conceptually. However, I'm not too sure about the practical differences between the two when it comes to making a choice architecturally. Here is what I want to know 1) Any good links online which can help me in this regard. 2) Can someone tell me where it makes sense to use on...
I've got a few methods that should call System.exit() on certain inputs. Unfortunately, testing these cases causes JUnit to terminate! Putting the method calls in a new Thread doesn't seem to help, since System.exit() terminates the JVM, not just the current thread. Are there any common patterns for dealing with this? For example, can I ...
If you have java.io.InputStream object how should you process that object and produce a String? Suppose I have an InputStream that contains text data, and I want to convert this to a String (for example, so I can write the contents of the stream to a log file). What is the easiest way to take the InputStream and convert it to a Strin...
I'm currently using Win32ShellFolderManager2 and ShellFolder.getLinkLocation to resolve windows shortcuts in Java. Unfortunately, if the Java program is running as a service under Vista, getLinkLocation, this does not work. Specifically, I get an exception stating "Could not get shell folder ID list". Searching the web does turn up ment...
Hi, GWT seems like a really nice technology for Java developers who don't like (or don't know) HTML/JS/CSS to build rich web interfaces. On the server-side Grails also looks really nice, it's often described as "Rails for Java developers". I've read that Grails' "convention over configuration" approach, together with the benefits of dyn...
I commonly find myself extracting common behavior out of classes into helper/utility classes that contain nothing but a set of static methods. I've often wondered if I should be declaring these classes as abstract, since I can't really think of a valid reason to ever instantiate these? What would the Pros and Cons be to declaring suc...
I'm using the StAX event based API's to modify an XML stream. The stream represents an HTML document, complete with DTD declaration. I would like to copy this DTD declaration into the output document (written using an XMLEventWriter). When I ask the factory to disregard DTD's it will not download the DTD, but remove the whole statement a...
In what cases is it necessary to synchronize access to instance members? I understand that access to static members of a class always needs to be synchronized- because they are shared across all object instances of the class. My question is when would I be incorrect if I do not synchronize instance members? for example if my class is...
I am creating an touch screen application using Swing and have a request to change one of buttons so that it will behave like a keyboard when the button is held down. (First of all, I am not sure that the touch screen will allow the user to "hold down" the button, but pretend that they can for now) I was going to go down the path of sta...
