Agreed - alternatives to XML could be handy and could be used by any 
user of spring, whether they intend to deploy in Geronimo or not.

e.g. in Groovy we could change something like this...


<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" 
"http://www.springframework.org/dtd/spring-beans.dtd">
<beans>
   <bean id="myDataSource"
class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
     <property 
name="driverClassName"><value>com.mysql.jdbc.Driver</value></property>
     <property 
name="url"><value>jdbc:mysql://localhost:3306/mydb</value></property>
     <property name="username"><value>root</value></property>
   </bean>

</beans>

into this Foo.groovy file

bean(id:"myDataSource", 
class:org.apache.commons.dbcp.BasicDataSource.class,
     destroy_method:"close",
     driverClassName:"com.mysql.jdbc.Driver",
     url:"jdbc:mysql://localhost:3306/mydb",
     username:"root")


Which saves a bit of typing, avoids the pointy bracket stuff and allows 
variables and expressions to be used (e.g. so the same script can be 
reused but at runtime use different parameterizable port numbers etc). 
Of course if ever you want if / while / for loops in your 
configuration, then the scripting language approach becomes a huge win.
