Overview

With the Settings4jFactoryBean you can define Objects in Spring Configuration.

Example

For example: You want configure your DataSource with Settitngs4j:
The following example could load your DataSource from the JNDI Context with Settings4j.getObject("com/myCompany/myDataSource")
The JNDIConnector will read the Object "java:comp/env/com/myCompany/myDataSource" from the JNDI Context.

  <bean id="myDataSource" class="org.settings4j.helper.spring.Settings4jFactoryBean">
    <property name="key"><value>com/myCompany/myDataSource</value></property>
  </bean>

Example Classpath Config with ObjectResolver

With Settings4j you can also configure the DataSource in your Classpath without requirement of a JNDI-Context:

Example Database Configuration with JavaXMLBeansObjectResolver:

create the Classpath File "com/myCompany/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>

and create the Classpath File "com/myCompany/myDataSource.properties":

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

Place Your DataSource Config into your Filesystem:

You can also start your Application with -Dcom/myCompany/myDataSource=file:/opt/myApp/config/myDataSource
Then the two Files "myDataSource" and "myDataSource.properties" must be place in "/opt/myApp/config/".
