NetBeans 8 新建web项目

我使用的netbeans版本是8.0.1，请先确保安装了J2EE相关插件。

1、打开netbeans，新建项目。

2、选择Java Web ->Java Application，然后next

3、项目名称自定义，我这里设置为“HelloJSP”，选择项目位置。Next。

4、会弹出让你选择服务器实例的窗口，这里选择“Apache Tomcat”，Next

5、选择tomcat的位置，设置用户。点击“Finish”




6、Next。


7、Finish。



至此，项目就建立好了。

生成完项目后，运行项目，



默认的浏览器会被打开并展示项目的首页：



在Tomcat的安装目录下的conf/Catalina/localhost目录下出现了文件HelloJSP.xml，其内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<Context antiJARLocking="true" docBase="/home/letian/NetBeansProjects/HelloJSP/build/web" path="/HelloJSP"/>

而Tomcat安装目录下的conf目录下的tomcat-users.xml中也增加了之前设置的用户：

<?xml version="1.0" encoding="UTF-8"?>
