Java paypal 调用从不返回结果

Question

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

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

Exception is as follows.

java.net.SocketException: Connection reset

目前我在类文件夹中使用代理是否需要任何证书或其他东西，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

我的代码如下

您能否检查您的 java.policy 文件以检查是否有任何限制或其他情况，也许您需要在此处添加 SocketPermission 以允许应用程序连接

Answer 2

这是一个 HTTP 代理问题。当我从网络中删除 HTTP 代理时，它已修复
