I'm trying to develop a standalone Java web service client with JAX-WS (Metro) that uses WS-Security with Username Token Authentication (Password digest, nonces and timestamp) and timestamp verification along with WS-Addressing over SSL. The WSDL I have to work with does not define any security policy information. I have been unable to...
Hi all, I must convert a char into a byte or a byte array. In other languages I know that a char is just a single byte. However, looking at the Java Character class, its min value is \u0000 and its max value is \uFFFF. This makes it seem like a char is 2 bytes long. Will I be able to store it as a byte or do I need to store it as ...
Suppose I'm using an interface with a generic type parameter interface Foo<T> { T getOne(); void useOne(T t); } The intention is that the type T is abstract: it enforces a type constraint on implementations of Foo, but the client code doesn't care exactly what T is. This is no problem in the context of a generic method: public <...
I was looking through patents authored by Lars Bak, when I realized a lot of them cover components of the the Sun JVM, HotSpot, etc. Now that parts Sun's stack is being released under FLOSS licenses, how does this affect people who are forking or using forks of this open source software? Are they not in violation of Sun's patents? ...
I have a Java project in a SVN repository, with a bunch of .java files, each of those files has a licence agreement flower box at the top of the file (I have customers which have licenced the source as well as running the product). Is there a good way to be able to modify / maintain the licence text in one place rather than having to up...

As the title says, is there an easy way to output two columns to the console in Java? I'm aware of /t, but I haven't found a way to space based on a specific column when using printf. ...
I already read the link checker question posted in SO. If there are more questions of this kind and I missed them, my apologies. We need to find broken links in a website in a very easy way and scriptable way, so we can document the links that are broken. I found a blog post with some code written in java that will do exactly what I ne...
I am developing a Java web application that bases it behavior through large XML configuration files that are loaded from a web service. As these files are not actually required until a particular section of the application is accessed, they are loaded lazily. When one of these files are required, a query is sent to the webservice to retr...

How can I manage the threads so that I can listen to all these clients simultaneously? Also, if in this case the server wants to send somethin...

I work on a team of Java programmers. One of my co-workers suggests from time-to-time that I do something like "just add a type field" (usu. "String type"). Or code will be committed laden with "if (foo instanceof Foo){...} else if( foo instanceof Bar){...}". Josh Bloch's admonition that "tagged classes are a wan imitation of a proper ...
I work on a task that involves moving/traversing from one application to another. The applications are in separate JVMs. While traversing to the other application, I keep track of the session ID. However, as I traverse back and forth, a new session gets created. Is there any way for me to get back the same session, using the sessionId...
