Spring 3.1.0.M1 and STS

[davidfoley]

Hi,

first of all, apologies for (i) perhaps posting to the wrong place and (ii) possibly not having a clear picture of the issue I'm having (new to spring, STS and maven, but experienced developer).

In a nutshell- basing a project on this article, I configured my POM to successfully obtain the project dependencies: Spring 3.1.0.M1, Spring Security 3.1.0.RC, and Spring Social 1.0.0.M2 respectively.

The first issue is that STS reports errors with servlet-context.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd">

    <context:property-placeholder location="classpath:config.properties"/>

    <context:component-scan base-package="com.example.whatever" />

    <!--  	 
        these settings in the mvc namespace cause the IDE issue
     -->
    <mvc:annotation-driven/>
    <mvc:view-controller path="/index.html" view-name="index"/>
    <mvc:view-controller path="/" view-name="index"/>
	 
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <bean class="org.springframework.social.web.connect.ConnectController">
        <constructor-arg value="${application.url}"/>
    </bean>
</beans>

The error I get in the IDE is

Error occured processing XML 'tried to access class org.springframework.core.convert.support.ArrayToCollectionConverter from class org.springframework.core.convert.support.DefaultConversionService'. See Error Log for more details

Unfortunately there are no more details in the error log. I don't want to confuse matters by hazarding a guess right now, so onto the second issue, which is when I start STS spring insight after dragging my project into the servers panel, I get this

Error creating bean with name 'org.springframework.dao.annotation.

the truncated stack looks like this

Can anybody hazard a guess to whats causing this? Is there a conflict going on between Spring 3.0 and Spring 3.1? Does Spring insight server need to be configured to use 3.1? Does the IDE? I really can't figure this out. Would JPA 1/2 collision be an issue?

I really appreciate any and all feedback. Thanks.
