Weblogic or JBoss?
I am a long time java developer on JBoss(and Tomcat). In the last year I had to develop over weblogic and I have to say - I really miss JBoss. Since my experience with weblogic is pretty shallow, I am asking the more experienced guys out there: Is there a reason for spending money on weblogic? Isn't JBoss giving you all that you need...
setSoTimeout on a client socket doesn't affect the socket
I have a Java application with three threads that open, each, a socket and connect to a server on different ports. I set so_timeout on each of these sockets after the connection to the server is established. After that the threads block waiting on read(). Only one of the threads times out after 20 seconds (which is the timeout I set). Th...

How can I access private class members in Java?
I have data model classes that contain private fields which are meant to be read-only (via a getter function). These fields are set by my JPA persistence provider (eclipselink) during normal operation, using the contents of the database. For unit tests, I want to set them to fake values from a mockup of the persistence layer. How can I d...
J2ME, Reading Cell-ID from Nokia S40
Reading around Nokia forums, It seems that accessing Cell-ID and related info from Nokia S40 series phones is virtually impossible unless your Midlet is signed, and even this would work only for S40 3rd Edition FP1 and above. I tried the following on a Nokia S40 Dev Platform 2 phone , using Java ME: System.getProperty("com.nokia.mid.ce...
AXIS2 and JAX-WS how can I change the SSL handshaking ?
I need to customize the SSL handshaking when calling a JAX-WS API on top of Axis2. I find no reference at all on how to do this. With Metro I can set a custom SSLSocketFactory, but that uses a non standard API. How do I get access to the Axis engine so that I can reconfigure it before sending a soap request ? ...
I know that java.net.URL tries to resolve the URL; does java.net.URI do the same?
A quick Google didn't turn up a definitive answer. If URI does do this, is there a widespread third-party library that won't do this? I just need some parsing, and I can't have unpredictable delays while the constructor attempts to resolve a URI? Thanks. ...

Thread-safety refactoring
I am trying to make a Java application thread-safe. Unfortunately, it was originally designed for a single-user mode and all the key classes are instantiated as singletons. To make matters worse, there is a whole bunch of interfaces working as constants containers and numerous static fields. What would be considered as a good practice in...
How can I generate pseudo-random "readable" strings in Java?
Generating a truly random string of a given length is a fairly straightforward (and already-well-covered) task. However; I'd like to generate a "pseudo" random string with the additional constraint that it be relatively easily readable (to a native-English reader.) I think another way to say this is to say that the generated string sho...

In Java, can I create an instance of an anonymous subclass from a Class object?

Suppressing / controlling logging in org.apache.xmlrpc.XmlRpcClient?
I have inherited some Java code that does some testing of our XMLRPC server. So far so good. Part of that code deals with stopping the server (a few repetitions of "check if server still there and if so send it command to shut down"). As the server is shutting down, some of these "is the server still there?" and/or "tell it to shut dow...
