Is it possible to use a DB sequence for some column that is not the identifier/is not part of a composite identifier? I'm using hibernate as jpa provider, and I have a table that has some columns that are generated values (using a sequence), although they are not part of the identifier. What I want is to use a sequence to create a new...
There exists a very good talk about C# vs. Java where H.Mössenböck compares the two languages. That's from 2003, C# 2.0 compared with Java 1.5. Can be found in German here: http://dotnet.jku.at/ What good resources exist, where actual language versions are compared? Or maybe post a comparison right here? My interests are: Advantages/...

I have to read a binary file in a legacy format with Java. In a nutshell the file has a header consisting of several integers, bytes and fixed-length char arrays, followed by a list of records which also consist of integers and chars. In any other language I would create structs (C/C++) or records (Pascal/Delphi) which are byte-by-by...
I'm looking for a way to do grouping with displaytag but with the group title separated from the detail. It's probably not all that clear, so here is an example : If I just add groups to a displaytag table, I end up with something like : | group1 | item1 | | | item2 | | | item3 | | group2 | item4 | | | item5 | I ...
I have an image that I want to show some 'spotlights' on, like they do on TV. The rest of the image should be darker than the original, and the person that I'm spotlighting should be normal. I have the x,y and radius of the spotlight, but I'm not sure how to change the brightness at that location. Also, if I have two spotlights and ...

I know wsdl2java works because I can run the examples but when I try it on the wsdl given to me it fails. The one big difference is that the WSDL given to me uses SSL. I’m using Java 1.4 (checked it a few time) and made sure ...

Using Maven 2, is there a way I can list out the jar dependencies as just the file names? mvn dependency:build-classpath can list the jar files, but that will include the full path to their location in my local repository. What I need is essentially just a list of the file names (or the file names that the copy-dependencies goal copie...
I am looking for a java library that will allow me to "trim" an audio file so that I can pull out and save X amount of seconds of an audio file. Ideally, I am looking for something that would be like a substr for an audio file. If I want from 123 seconds in to 153 seconds in I would be able to do: coollib.load('bigfile.mp3'); coolli...
Okay, my company is a bank. The upper management is dead set on a websphere IBM portal. Apparently IBM is tossing them a bone they can't refuse. We're also a very big IBM shop anyhow with A LOT of LotusNotes applications. In my experience with IBM, they generally make you go through them to learn their stuff. I'm having to sort of jump ...

It is as if the updates.jar library cannot be found or read. If I launch the same line ...
