Java paypal调用从不返回结果

Java我正在使用paypal网站pro sdk SOAP调用问题是以下代码行在长时间后返回异常

response = (CreateRecurringPaymentsProfileResponseType) caller.call("CreateRecurringPaymentsProfile", request);

Exception is as follows.

java.net.SocketException: Connection reset

我需要任何证书或其他东西吗？目前我正在使用classes文件夹中的proxy，如下所示

# This file contains the properties that needs to be set to make the API call via Proxy.


# To make use of proxy, change PROXY_SET to true, uncomment 
# PROXY_HOST and PROXY_PORT properties and set values as illustrated below.
# Note: Just remove the # symbol to uncomment. 
# Both  PROXY_HOST and PROXY_PORT needs to be set. PROXY_PORT should be a number.
# If any one of these properties are not set or invalid, proxy settings will be ignored
# and this information will be logged.

# PROXY_HOST : IP Address or Host Name of the proxy server
# PROXY_PORT: Port number of the proxy server

 PROXY_SET = true 

 PROXY_HOST=128.1.100.13
# eg: PROXY_HOST = 127.0.0.1

 PROXY_PORT=8080
# eg: PROXY_PORT = 808

# The following properties are optional.
# If your proxy need username and password to authenticate, 
# just uncomment the following two properties and set values as illustrated below.
# Note: Just remove the # symbol to uncomment. 

# PROXY_USERNAME=<your proxy username>
# eg: PROXY_USERNAME =test

# PROXY_PASSWORD=<your proxy password>
# eg: PROXY_PASSWORD =test

在developer.paypal.com网站上，我创建了以下帐户

编辑出于安全原因删除。

能否检查java.policy文件以检查是否存在任何限制或其他问题，可能需要在此处添加SocketPermission以允许应用程序连接

这是一个HTTP代理问题。当我从网络中删除HTTP代理时，它已被修复

祝贺你，你刚刚告诉了数百万人你的PayPal帐户的密码。马上换。还有你的银行账户详细信息。预计未来几个月易趣用户会有很多抱怨，因为有人会用你的名字开立账户，并进行大规模欺诈。哈哈，你认为我很愚蠢，我提供了原始通行证……；）这些都是测试帐户，顺便说一句，dun担心如果你想删除它再次发布（没有敏感位），请标记它以引起版主注意。我已经授予了连接权限，但仍然没有luckabove代码与直接连接到internet的计算机完美配合。我是代理的幕后黑手，因此出现此错误。我已经设置了代理配置，但仍然没有luckproxy可能会阻止某些协议的响应，请尝试其他返回soap的web服务，如果该服务正常，则此应用的代理配置不正常。
