我正在尝试将.xml文件形式的响应从Java servlet发送到客户端。为此我写了下面的代码:
if (result) {
response.setContentType("text/xml");
PrintWriter out = response.getWriter();
out.println("<Login>");
out.println("<status>"+successStatus+"</status>");
out.println("<username>"+userDTO.getFirstname()+"</username>");
out.println("<sessionId>"+hSession.getId()+"</sessionId>");
out.println("<timestamp>"+hSession.getLastAccessedTime()+"</timestamp>");
out.println("<timeout>"+hSession.getLastAccessedTime()+"</timeout>");
out.println("</Login>");
}
如何检查客户端是否收到此回复? 我是否需要明确发送响应,或者上面的代码是否足以将响应发送给客户端?

只需调用servlet的URL就可以到达客户端(浏览器)。你不需要做任何具体的事情。
所以,如果你的servlet是这样映射的,
<servlet>
<servlet-name>MyServlet</servlet-name>
<servlet-class>com.test.MyServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>MyServlet</servlet-name>
<url-pattern>/MyServlet</url-pattern>
</servlet-mapping>
只需调用URL http://www.example.com/context/MyServlet
即可在浏览器中获取XML!

public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("<HTML>");
out.println("<HEAD><TITLE>Hello World</TITLE></HEAD>");
out.println("<BODY>");
out.println("<BIG>Hello World</BIG>");
out.println("</BODY></HTML>");
}
}
