A Simple Configuration Manager Architecture

This is a simple configuration architecture I use for my small applications these days. I'm happy with it now.

I have

• A Singleton Application Manager, which represent the business layer of my application information.
• Configuration Manager is also a Singleton class, but not necessary to be Singleton. Application Manager is the only class which would have relationship with Configuration Manager. The later one is a reusable class, providing DAO implementations to XML based Properties accessing to configuration files.
• Configuration items are represented by POJO/JavaBeans, provided annotation on each field.
• Application Manager parses the configuration POJO and retrieve configuration items via Configuration Manager, and saves the POJO as configuration items via Configuration Manager.

Something more:

• A DAO layer.
• Spring
• Apache Configuration

NetBeans JAXB Problem: typedef class com.sun.tools.xjc.XJCTask cannot be found

Phenomenon:
I developed a JAXB application using JAXB Wizard on Netbeans 6.7.1. I submitted the program to SVN and then checkout into another computer. When I tried to compile the program, I met an error as:

D:\......\xml_binding_build.xml:8: typedef class com.sun.tools.xjc.XJCTask cannot be found

Reason:
Netbeans projects uses nbproject/private directory to contain some system dependent attributes. I usual ignore this directory when I submit my application to a version control system. However, Netbeans puts the JAXB path information in this directory, which cause my the compilation problem.

jaxws.endorsed.dir=D:\\Program Files\\NetBeans 6.7.1\\java2\\modules\\ext\\jaxws21\\api:D:\\Program Files\\NetBeans 6.7.1\\ide11\\modules\\ext\\jaxb\\api

Due to my understanding, I think this must be a bug of JAXB Wizard in Netbeans.

Solution:
Create another project in the current Netbeans environment and run JAXB Wizard once. Look at the nbproject/private/private.properties file, copy the corresponding line into your target JAXB application, clean and build the application.
