The problem is simple, but I'm struggling a bit already. Server server = new Server(8080); Context context = new Context(server, "/", Context.NO_SESSIONS); context.addServlet(MainPageView.class, "/"); context.addServlet(UserView.class, "/signup"); server.start(); That's a pretty standard piece of code that you can find anywhere in J...
I have an Eclipse RCP app running on Java 6. When I try to run the product configuration from within Eclipse, it silently terminates almost immediately. No error is reported in the console. I've tried setting breakpoints in the IApplication and in the Activator, and neither are reached. I know I don't have much specific information h...
I am pulling a long timestamp from a database, but want to present it as a Date using Tags only, no embedded java in the JSP. I've created my own tag to do this because I was unable to get the parseDate and formatDate tags to work, but that's not to say they don't work. Any advice? Thanks. ...
I have a JSP page that contains a scriplet where i instantiate an object. I would like to pass that object into the JSP tag without using any cache.

Has anyone used the new Java 1.6 JDK tool, VisualVM, to profile a production application and how does the application perform while being profiled?

Does anybody have experience of a decent J2SE (preferably at least Java JDK 1.5-level) Java Virtual Machine for Windows Mobile 6? If you know of any CLDC VMs, I'm also interested because even that would be better than what we currently have for the platform. ...
I've only been able to find two thus far, namely TinyRadius, which itself discourages production use and AXL, which is pay-only. JRadius seems tied to FreeRADIUS, which isn't a library and will need a lot of cajoling to function like one. ...
I am working on a project where the requirement is to have a date calculated as being the last Friday of a given month. I think I have a solution that only uses standard Java, but I was wondering if anyone knew of anything more concise or efficient. Below is what I tested with for this year: for (int month = 0; month < 13; month++)...
Any advise on how to read auto incrementing identity field assigned to newly created record from call through java.sql.Statement.executeUpdate ?

Is there a tool to detect unneeded jar-files? For instance say that I have myapp.jar, which I can launch with a classpath containing hibernate.jar, junit.jar and easymock.jar. But actually it will work fine using only hibernate.jar, since the code that calls junit.jar is not reachable. I realize that reflection might complicate things,...

I'm writing a Java application that runs on Linux (using Sun's JDK). It keeps creating /tmp/hsperfdata_username directories, which I would like to prevent. Is there any way to stop java from creating these files? ...
An array of ints in java is stored as a block of 32-bit values in memory. How is an array of Integer objects stored? i.e. int[] vs. Integer[] I'd imagine that each element in the Integer array is a reference to an Integer object, and that the Integer object has object storage overheads, just like any other object. I'm hoping however ...
