HTTP 状态 500 - 内部服务器错误
输入异常报告
消息内部服务器错误
说明服务器遇到内部错误，无法完成此请求。
异常 javax.servlet.ServletException：类 test.testing1 不是 Servlet
根本原因 java.lang.ClassCastException: test.testing1 不能转换为 javax.servlet.Servlet
像这样尝试：
public class testing1 extends PDFTOEXCEL implements Servlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
out.println("converted sucessfully");
}
}
@Override
public void destroy() {
// TODO Auto-generated method stub
}
@Override
public void init(ServletConfig config) throws ServletException {
// TODO Auto-generated method stub
}
@Override
public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException {
processRequest((HttpServletRequest)req, (HttpServletResponse)res);
}
}
