First, the following is the physical path of my web application.
...
---BankAccount
└ WEB-INF
│ └classes
│ │ └webapplication
│ │ └AccountServlet.class
│ │ └LoginServlet.class
│ └web.xml
└ login.html

I try to access the URL "http://127.0.0.1:8080/BankAccount/login.html",which the login.html post a request to the servlet LoginServlet which is in the package webapplication.Then the LoginServlet will redirect to the AccountServlet if the login is ok.I use the req.getRequestDispatcher("/AccountServlet").forward(req, res) to get the user's account info.However, the question arised here.In the book, it use the req.getRequestDispatcher("/servlet/AccountServlet").forward(req, res) and also will sucess.It is strange about the /servlet/... What does the path means?I don't have such package or directory.
I tried some other web application then and I found that the path "/servlet/..." all work well.Can anyone help me?

Hi Simeon
Good question. Confuses me as well. I think the /servlet is a default directory in the Servlet deployment structure.
See this link in the SCWCD thread, where similar concerns are raised.

You should view web.xml file to see servlet mapping configration.
For example:
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
</servlet>

<!-- Action Servlet Mapping -->
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>/Servlet/ActionServlet</url-pattern>
</servlet-mapping>
Then you can visit ActionServlet.class through the url "http://localhost/Servlet/ActionServlet"
Hope it can help you.

Actually,I made the web.xml by myself in which I didn't assign the <servlet-mapping> tag.
 
I agree. Here's the link: http://aspose.com/file-tools
