Comment on JMX remote monitoring on Linux by Joan

Be careful if you have the -b ${IP_ADRESS} in java opts cause it can produce troubles on jmx port binding.
Probably you have to change the $(hostname) to the defined binding adress.

Comment on JAXB and creating elements from schema types by Samuel Van Reeth

A part of my previous post seems to be missing

This is block to add in your schema:
xs:annotation>
xs:appinfo>
jaxb:globalBindings>
xjc:simple />
/jaxb:globalBindings>
/xs:appinfo>
/xs:annotation>

Hi,

I had exactly the same problem, and I found the following blogpost:
http://weblogs.java.net/blog/2006/03/03/why-does-jaxb-put-xmlrootelement-sometimes-not-always

The solution is very simple: put the following block in your schema:

and add the following lines to the tag:
xmlns:jaxb=”http://java.sun.com/xml/ns/jaxb”
jaxb:version=”1.0″
xmlns:xjc=”http://java.sun.com/xml/ns/jaxb/xjc”
jaxb:extensionBindingPrefixes=”xjc”

This will force JAXB to generate the @XmlRootElement annotation

I hope this also solves your problem

Comment on Live patterns: Switching to the visitor design pattern by Frood

Frood — Wed, 16 Jun 2010 12:33:40 +0000

@Dimitris:
The Visitor pattern buys you a bit more than that: You can put the code into the layer it rightfully belongs to. So, the visitors concerning UI go to the UI code and the ones concerning business logic go to the business code etc. Without visitors you have to either put the code into the objects themselves, thus blurring the layers, or replicate the objects inside a layer, being cumbersome and error-prone.
Besides, in case of hierarchies you can use walkers to traverse object trees, in which visitors act as a kind of beefed-up lambda expressions. Very handy

Comment on Live patterns: Switching to the visitor design pattern by Dimitris Andreou

Well, I don’t think this is the life-saver you seem to be describing…

What visitor buys you here is merely the fact that you don’t have to put an abstract method plus implementations for each distinct type-based desicion (bloating a single file), but create those implementations externally (out of the itinerary source files). I.e. you just managed to avoid putting the type-based code in the types themselves, but somewhere else. Good for you. Where would we be without patterns!

Btw, Scala supports the switch you describe (where the compiler notifies you of missed cases).
