I have a JTable and a TableRowSorter which I'd like to perform an operation after a sort is finished. I've been browsing the net, and so far I haven't had much luck. Initially I thought just a RowSorterListener would do the trick, but unfortunately it doesn't perform the operation after the sort is finished. Adding a MouseListener to t...
When creating modules on the NetBeans platform, the FileObject object represents a file in the virtual file system of the IDE. Creating new FileObjects is simple, but does NetBeans completely control the reference to the actual File, or should I close FileObject myself? My code is like this: FileObject appRoot = FileUtil.getConfigRoot()...

I was recently tasked with architecting a new scalablable user phone directory. Basically you'll have phone resellers logging into a portal and selling their phones to customers (who also need to be added into the system). So if I bought 3 phones from the reseller for my family, then each phone is automatically on the network (done by ...
I am currently writing a Turret Defense style game using the GTGE engine, this engine has the ability to use either JOGL or LWJGL to drive the graphics and so I was wondering, which one should I use? What are the pros/cons of each? What factors should I consider when deciding? ...
Hello to all, I've made a web application using Java, Struts and running over Apache Server and Tomcat. It would be very useful to be able to restart the application from the web. I don't want to restart Tomcat, only this wbapp, the same way as Tomcat Manager does it. Do you know how can I do it? If not, any way to simulate that behavi...

I'm using JDK 1.4...so I don't have access to the nice concurrency stuff in 1.5+. Consider the following class fragment: private Map map = Collections.EMPTY_MAP; public Map getMap() { return map; } public synchronized void updateMap(Object key, Object value) { Map newMap = new HashMap(map); newMap.put(key, value); map...

I'm looking for pointers to something that I may be overlooking (or maybe something that Jivebot hasn't yet written for me). What I want is a pre-rolled Java framework for managing user accounts that takes care of most of the common tasks associated with such. For instance, Jfacets is a good approach to automagic view controlling, but y...
I've written a java applet that connects to Oracle on a hosted server. I have been testing it by connecting by VPN to my hosting service and connecting to the Oracle database. I've done this so I don't have to expose the Oracle db to outside connections, but now I need to be able to connect to Oracle without being on the VPN. Is there...
I am writing a program that generates a pdf or rtf file with a table in it, using iText. I used the iText class table and cell, rather than the more specific RtfTable or pdfTable so that either file can be generated at the end. I needed to set the cell padding to a value of -1, or else there was too much space between each row of data ...
I'm new to Flex development, and RIAs in general. I've got a CRUD-style Java + Spring + Hibernate service on top of which I'm writing a Flex UI. Currently I'm using BlazeDS. This is an internal application running on a local network. It's become apparent to me that the way RIAs work is more similar to a desktop application than a web...

I cannot alter this in code, but I would like eclipse to stop complaining about the annotation, as I can still build with maven. How would I go about disabling this error? Note: Due to project requirements, I need ...

Is there a quick way in java to get the nest/recurse level? I'm writing a function to make a list of Groups and their members. The members can be groups as well. It's possible that we could end up with a circular set of groups/member. I would like to stop at some arbitrary level. I know I could just keep a variable in a higher scope...
