使用Eclipse/Weblogic开发的一个问题

　　以前一直用tomcat，这两天试用了一上weblogic10R3，真有点不适应，开发环境搭建费了好半天的事儿。终于把插件装上，运行一个小例子。又报了个这样的错：

　　大意是说：域编辑功能被另外一个session锁定，可以通过管理控制台禁用“自动获取锁并启用配置的变化Automatically Acquire Lock and Activate Changes”。
　　打开控制台，找了半天，后来依照下面的官方帮助，终于解决了。

Enable and disable the domain configuration lock

The Administration Console Change Center provides a way to lock a domain configuration so you can make changes to the configuration while preventing other accounts from making changes during your edit session.

The domain configuration locking feature is always enabled in production domains. It can be enabled or disabled in development domains. It is disabled by default when you create a new development domain.

To enable or disable the domain configuration locking feature in a development domain:

In the banner toolbar region at the top of the right pane of the Console, click Preferences.
Click User Preferences.
Select or clear Automatically Acquire Lock and Activate Changes to enable or disable the feature.
Click Save.
