分享新手：用Myeclipse 10第一次创建servlet 里面的package提示错误
tomcat 7x 都配置部署好了，上http://localhost:8080/TestTomCat也能看到内容了。

public FirstServlet() {
super();
}

super.destroy(); // Just puts "destroy" string in log
// Put your code here
}

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {

out.println(", using the GET method");
out.println(" </BODY>");
out.println("</HTML>");
out.flush();
out.close();
}

}
servlet.api的包也导入了，自己学实在太费劲了，一步一出错，哪位前辈能帮忙看看怎么解决？

你好楼主，遇到和你同样的问题搞了两天了，快疯了，也是一枚自学党，1.8jdk匹配的应该是tomcat.8，切换到(MYeclipse自带)1.6JDK后，红叉去掉后但是编译当前目录下的index.JSP文件，会报异常，点击确定以后会跳转到另一个web项目下的，index.jsp页面，jsp文件没有异常，就是servlet不行，其他包都可以

方法1.选择Eclipse的Window→Preferences→Java→Compiler，把Compiler compliance level从1.5改成1.6；
方法2.右击project选择最后一个properties选择左侧的java compiler,勾选里面的框框，把java编辑器版本都改成1.6；
方法3.右击project下的 JRE System Library[JavaSE-1.5]→Properties,Execution environment 选择“JavaSE-1.6(JDK1.6.0_10)”,点击确定即可。
