这是我的代码...基本的 servlet 代码。
//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;
}
}
编译它......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”编辑了它!!!
它在其他机器上运行，而在我的机器上显示以下错误响应。
我正在使用 Win 7(64 位)...我想没必要!!

7 errors
我该怎么办？
最佳答案
您的类路径中应该有 servlet-api.jar。它应该存在于 weblogic81\server\lib\ 目录中。
关于java - 即使设置类路径后，包 javax.servlet 也不存在，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11239170/
