编译servlet:包javax.servlet不存在,java,servlets,Java,Servlets,我在cmd上编译这个servlet程序时遇到问题，我在cmd上使用它设置了weblogic.jar文件的类路径-set classpath=C:\Oracle\Middleware\wlserver\u 12.1\server\lib\weblogic.jar 我的代码是- import javax.servlet.http.*; import javax.servlet.*; import java.io.*; public class DemoServlet1 implements Serv

我在cmd上编译这个servlet程序时遇到问题，我在cmd上使用它设置了weblogic.jar文件的类路径-

set classpath=C:\Oracle\Middleware\wlserver\u 12.1\server\lib\weblogic.jar
我的代码是-
import javax.servlet.http.*;
import javax.servlet.*;
import java.io.*;
public class DemoServlet1 implements Servlet 
{
public void init(ServletConfig con)
{}
public void service(ServletRequest req,ServletResponse res)throws     ServletException,IOException
{
    res.setContentType("text/html");
    PrintWriter out=res.getWriter();
    out.println("<html><body>");
    out.println("hello servlet !!!!");
    out.println("</body></html>");
}
public void destroy()
{}
public ServletConfig getServletConfig()
{
    return null;
}
public String getServletInfo()
{
    return null;
}
}

类路径中应该有servlet-api.jar。另请参阅以下链接
