Hi,

I was following Maven EJB sample trying to add Persistence Unit to the empty project, when I click the "finish" button, an error occurred like:

java.lang.ArrayIndexOutOfBoundsException: 0

I searched in this site, and found many similar bugs, I don't know if they are same one.

Anyway I report it.

thanks!

BTW, I'm using NetBeans 7.2, and another question:
the 7.2 version uses Spring 3.1, why the IDE generates applicationContext.xml like:
xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-2.5.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-2.5.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-2.5.xsd

why 2.5?
