Java Web开发工具配置常见问题

发表时间：2022-03-25来源：网络

问题一：

The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path

解决方案：

刚开始用Myeclipse，把以前eclipse下的工程复制过来后，发现缺少Server Runtime。
本想直接在buildpath里加lib，在Myeclipse里找了一圈，恁是没发现在哪里可以添加，虽然在preference里enable了tomcat，但是add library选择WTP Server Runtime后的框里给偶一白板，晕乎。
网上找了一下，解决方法如下：
1,File->New->Other->Server->Apache->Tomcat v6.0 Server
注意在new时，别忘了勾上Show All Wizards
2,Project->Properties->Java Build Path->Libraries->Add Library->WTP Server Runtime(MyEclipse incompatible)->next->Tomcat v6.0 Server->Tomcat v6.0 Server

大功告成 :-)

MyEclipse新建Web Project 之后显示警告信息，我们想除之而后快。
