我目前正在进行一个项目，该项目使用NetBeans 8.2、jdk 1.8.0_311和glassfish 5.0将PayPal支付集成到Java Maven Web应用程序中。
共有两个文件，
** checkout .jsp：**
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Check Out</title>
<style type="text/css">
table { border: 0; }
table td { padding: 10px; }
</style>
</head>
<body>
<div align="center">
<h1>Check Out</h1>
<br/>
<form action="./authorize_payment" method="post">
<table>
<tr>
<td>Product/Service:</td>
<td><input type="text" name="product" value="Next iPhone" /></td>
</tr>
<tr>
<td>Sub Total:</td>
<td><input type="text" name="subtotal" value="100" /></td>
</tr>
<tr>

<td><input type="text" name="shipping" value="10" /></td>

<tr>

<tr>
<td colspan="2" align="center">
<input type="submit" value="Checkout" />
</td>
</tr>
</table>
</form>
</div>
</body>
</html>和授权支付.java（servlet）：
package net.codejava.mavenproject1;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.*;
import com.paypal.base.rest.PayPalRESTException;
@WebServlet("/authorize_payment")
public class authorize_payment extends HttpServlet {
private static final long serialVersionUID = 1L;
public authorize_payment() {

protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String product = request.getParameter("product");
String subtotal = request.getParameter("subtotal");
String shipping = request.getParameter("shipping");
String tax = request.getParameter("tax");
String total = request.getParameter("total");
OrderDetail orderDetail = new OrderDetail(product, subtotal, shipping, tax, total);
try {
PaymentServices paymentServices = new PaymentServices();
String approvalLink = paymentServices.authorizePayment(orderDetail);
response.sendRedirect(approvalLink);
} catch (PayPalRESTException ex) {
request.setAttribute("errorMessage", ex.getMessage());
ex.printStackTrace();
request.getRequestDispatcher("error.jsp").forward(request, response);
}
}
}当我单击checkout.jsp上的“checkout”按钮时，它显示：

我已经尝试将jdk版本降级到jdk1.8.0_151、jdk1.8.0_181、jdk1.8.0_221和jdk1.8.0_291，但是我还是得到了同样的错误。我也试着用glassfish server 5.1运行这个程序，但是仍然没有成功。我也试着删除grizzly-npn-bootstrap.jar中的sun文件如this post中所建议的，但不幸的是，它没有工作。
我希望有人能帮我找出问题所在，因为我已经试着解决它将近一个星期了，它让我发疯。

首先，这是由于webapp配置错误。您需要阅读该链接，并采取建议的操作来获得正常运行的日志记录。
然后这些来自不同版本的Java8
HelloExtension和SSLExtension类是内部类，前者被后者替换。但是请注意，
NoClassDefFoundError异常可能并不意味着类丢失了，它们可能意味着类静态初始化失败了......或者类所依赖的类静态初始化失败了。我本以为会有其他堆栈追踪Map到初始化失败。可能是因为记录组态问题而遗失。
目前还不清楚实际的问题是什么，但看起来在SSL代码的初始化过程中出现了故障。一种可能性是SSL设置有问题。
我的建议是：
1.首先修复日志记录问题。
1.接下来使用最新版本的Java8。使用过时的Java8版本有帮助的可能性几乎为零。
1.检查您在Web容器中使用的所有SSL设置。
1.查找 * 其他 * 堆栈跟踪，解释 * 为什么 * 发生以下情况：
