今天写代码时，发现HttpServletResponse response = ServletActionContext.getResponse();这句报红叉，提示The type javax.servlet.http.HttpServletResponse cannot be resolved. It is indirectly referenced from required .class files，并要求configuration build path，经过尝试之后，发现解决办法。
错误情况：HttpServletResponse response = ServletActionContext.getResponse();这句报红叉
提示：The type javax.servlet.http.HttpServletResponse cannot be resolved. It is indirectly referenced from required .class files，并要求configuration build path
解决办法：点击提示中的configuration build path（或者右键项目，点击Build Path->configuration build path），打开build path界面后，选择Libraries选项卡，并单击Add Library，如图
选择MyEclipse Libraries，点击Next
找到Java EE 5，点击Finish
再看代码，红叉已经解决
