I have this weird error in a .jsp page in eclipse:
我在eclipse的.jsp页面中有一个奇怪的错误:
javax.servlet.jsp.PageContext cannot be resolved to a type
My project is a maven project imported into "as an existing maven project" into juno with m2e and m2e-wtp plugins installed.
我的项目是一个maven项目，它被导入到juno中，并安装了m2e和m2e-wtp插件。
Is this a bug of the m2e plugins ? If yes, what's a possible workaround to get rid of this error (and the red mark in the workspace explorer) ?
这是m2e插件的bug吗?如果是，可能的解决方法是如何处理这个错误(以及工作区浏览器中的红色标记)?
Otherwise, do I need to "tell" to maven that my project contains jsp pages ? And hopefully, the m2e plugin will add the right library to the classpath. If yes, how ?
否则，我是否需要“告诉”maven我的项目包含jsp页面?希望m2e插件可以将正确的库添加到类路径中。如果是,如何?

The solution that worked for me, is given in this answer. Go to project properties > Targeted runtimes > Select the checkbox for a runtime (Apache Tomcat 7 in my case).
That's all. Just build the project now and everything will be fine.
这个答案给出了对我有效的解。转到项目属性>目标运行时>选择运行时复选框(在我的例子中是Apache Tomcat 7)。这是所有。现在就开始做这个项目，一切都会好起来的。

After upgrading to Kepler and updating all plugins, the issue disapeared. It was probably a bug.
在升级到开普勒并更新所有插件后，这个问题消失了。它可能是一个bug。
