我的GAE应用：清风记账本（[url]http://www.scholers.co.cc[/url]）
升级成spring2.5.6之后，想充分利用spring2.5里面的新的特性：
@Autowired，@Component等，可以大量的减少xml的配置，更加灵活方便。
但是使用这些新特性之后，发现上传上去（我的开发环境是GAE SDK1.4.2）之后，出现错误信息如下：

org.springframework.beans.factory.BeanCreationException: Error creating
bean with name
'org.springframework.context.annotation.internalPersistenceAnnotationProcessor':
Initialization of bean failed; nested exception is
java.lang.NoClassDefFoundError: javax/naming/NamingException

经过GOOGLE一把，发现老外已经发现了此类错误。具体在：
[url]http://code.google.com/p/googleappengine/issues/detail?id=1240[/url]
上面提示说，这个问题在使用spring3.0之前的版本都存在，于是我又屁颠屁颠的升级到spring3.0.5，果然这个问题解决掉了。

完整的错误信息：

org.springframework.beans.factory.BeanCreationException: Error creating
bean with name
'org.springframework.context.annotation.internalPersistenceAnnotationProcessor':
Initialization of bean failed; nested exception is
java.lang.NoClassDefFoundError: javax/naming/NamingException
