情况是这样的：
我写一个Java文件，内容如下：
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet
{
public voiddo
Get(HttpServletRequest request, HttpServletResponse
response)throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<body>");
out.println("<head>");
out.println("<title>Hello World!</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Hello World!</h1>");
out.println("</body>");
out.println("</html>");
}
}
然后编译，出现如下的错误，不知道如何解决，请各位大虾帮忙：
HelloWorld.java:2: package javax.servletdo
es not exist
import javax.servlet.*;
^
HelloWorld.java:3: package javax.servlet.httpdo
