在创建web项目完成后，可能出现的问题及其解决方法：

Q1、The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path 的错误

解决办法：点击项目右键>>Build Path>>Configure Build Path，如下图操作。

点击next，选择一个自己配置好的tomcat服务

![70 6][]

点击finish，然后点击Apply 并 OK即可

Q2:在更改Dynamic Web Module的版本时(2.3->3.0)，出现Cannot change version of project facet Dynamic web module to 3.0错误。

说明：我们用Eclipse创建Maven结构的web项目的时候选择了Artifact Id为maven-artchetype-webapp，由于这个catalog比较老，用的servlet还是2.3的，而一般现在至少都是3.0，在Project Facets里面修改Dynamic web module为2.5的时候就会出现Cannot change version of project facet Dynamic web module to 2.5

解决：

1、更改项目的web.xml文件，把servlet改为3.0

修改前：

修改后：

![70 9][]

2、修改.settings目录下的文件。打开Navigator视图：window>>Show View，选择Navigator，

2.1在Navigator视图下，打开项目下的.settings目录下的org.eclipse.jdt.core.prefs，把1.5全部改为1.7

![70 10][]

2.2 打开org.eclipse.wst.common.project.facet.core.xml

修改前：

![70 11][]

修改后：

![70 12][]

到此，已经Dynamic web module 2.3修改成3.0版本

![70 13][]

Q3:jdk版本不对，默认是jdk1.5，版本过低

解决：点击项目右键>>properties>>Java Build Path>>Libraries>>JRE System Library>>Edit，

选择当前环境的jdk

![70 14][]

点击finish>>Apply>>OK

![70 15][]

Q4：设置部署程序集(Web Deployment Assembly)，部署时的文件发布路径

解决：点击项目右键>>properties>> Deployment Assembly

![70 16][]

Q5、eclipse成功配置了tomcat,并且启动成功,eclipse的console显示的信息也都正确,但是浏览器访问时却提示404错误

新建本地Tomcat server后，双击server将其打开，进行如下配置

![70 18][]

在modules页签中，配置好访问的根路径

![70 19][]

配置好server，并运行后访问工程成功！
