java - Eclipse无法创建html/jsp文件

Question

我正在使用Eclipse Kepler javaee版本。当我尝试创建HTML或JSP时，显示this错误，如果创建文件，则显示它正在创建。我更新 eclipse 后会发生此问题。如何解决此错误？我的日志文件中出现错误，

Answer 1

发生这种情况的原因是，您正在不应包含JSP文件的文件夹中创建JSP。

最相似的原因是，Web部署程序集中未指定要添加JSP文件的文件夹。右键单击项目并选择“属性”，即可找到Web部署程序集。确保指定WEB-INF的父文件夹。

我曾经遇到此错误，然后通过上述步骤解决了该错误。
