How to insert jsp pages under a WEB-INF into frameset

In my graduation project, I put all the jsp pages in the WEB-INF folder. However, a problem occurs. WEB-INF is a protected folder, and we cannot access the resources in it through the regular method, that is, if we write the following code in frameset, it cannot be accessed:

1 <frame src="/WEB-INF/page/admin_righr.jsp" name="main" marginwidth="0" marginheight="0" frameborder="0" scrolling="auto"/>

The above code reports a 404 error.

 

So how can we solve this problem? There are three solutions:

I. Use Struts Framework

1. When src is configured in the frame, point it to an action.

1 <frame src="${pageContext.request.contextPath }/adminIndex/toAdmin_toAdminRight.action" name="main" marginwidth="0" marginheight="0" frameborder="0" scrolling="auto"/>

 

2. Return a string in the processing method. Then point to the jsp file to be loaded when processing results in struts. xml.

1     /**2      * admin_right.jsp3      */4     public String toAdminRight(){5         return "adminRight";6     }

1 <package name="adminIndex" namespace="/adminIndex" extends="struts-default">2         <action name="toAdmin_*" class="adminIndexAction" method="{1}">3         <result name="adminRight">/WEB-INF/page/backstage/admin_right.jsp</result>4         </action>5     </package>

Ii. Use Servlet

1 <servlet>2 　　<servlet-name>servletName</servlet-name>3 　　<jsp-file>/WEB-INF/admin_right.jsp>4 </servlet>5 <servlet-mapping>6 　　<servlet-name>servletName</servlet-name>7 　　<url-pattern>/.do</url-pattern>8 <servlet-mapping>

Then you can point to the servlet.

 

3. Use <jsp: forward page = "WEB-INF/XXX"> to directly access the jsp under the web-inf directory.
