这里是我的代码...一个基本的servlet代码后不存在。包的javax.servlet甚至设置类路径
//Servlet (interface)
import javax.servlet.*;
import java.io.*;
public class DemoServlet1 implements Servlet
{
public void init(ServletConfig config)
{ }
public void service (ServletRequest req, ServletResponse res)
throws ServletException, IOException
{
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("<html><body>");
out.println("WELCOME SERVLET");
out.println("</body></html>");
}
public void destroy()
{}
public ServletConfig getServletConfig()
{
return null;
}
public String getServletInfo()
{
return null;
}
}
COMPILING it ....它抛出javax.servlet不存在。 类路径和路径是正确的,因为我“ctrl c + ctrl v”编辑它!
及其在其他机器上运行,同时它在我的显示下面的错误响应。 我使用赢7(64位)...没有必要我猜!

我该怎么办?
您可以在javac命令本身中提供类路径,例如'javac -cp C:\ beaB \ weblogic81 \ server \ lib \\ *。jar DemoServlet1.java' –
