org.settings4j.objectresolver

Class JavaXMLBeansObjectResolver

java.lang.Object

org.settings4j.objectresolver.AbstractObjectResolver

org.settings4j.objectresolver.JavaXMLBeansObjectResolver

All Implemented Interfaces:

ObjectResolver

public class JavaXMLBeansObjectResolver
extends AbstractObjectResolver

This ObjectResolver convert a byte[] to an Object with the XMLDecoder.

Example: The following code should return a DataSource Object:
Settings4j.getObject("com/myCompany/myApp/MyDatasource");

In normal Cases the DataSource comes from the JNDI-Context (available in most Servlet Containers).
But in some environments there are no JNDI-Context (Commandline-Clients, UnitTests).

With Settings4j (default configuration) you can also place two Files into your Classpath:

1. "com/myCompany/myApp/MyDatasource": The File which defines the DataSource
2. "com/myCompany/myApp/MyDatasource.properties": Some Properties, like which ObjectResolver should be use.

The File Content whould be the following:

 Classpath File "com/myCompany/myApp/MyDatasource.properties":
 

 objectResolverKey=org.settings4j.objectresolver.JavaXMLBeansObjectResolver
 cached=true
 

 Classpath File "com/myCompany/myApp/MyDatasource":
 

 <?xml version="1.0" encoding="UTF-8"?> 
 <java version="1.6.0_05" class="java.beans.XMLDecoder"> 
  <object class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
   <void property="driverClassName"> 
    <string>org.hsqldb.jdbcDriver</string> 
   </void> 
   <void property="password"> 
    <string></string> 
   </void> 
   <void property="url"> 
    <string>jdbc:hsqldb:mem:test</string> 
   </void> 
   <void property="username"> 
    <string>sa</string> 
   </void> 
  </object> 
 </java>
