weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection
提问by KmrGtm
I am getting "java.lang.ClassCastException" while trying to connect to a url using javax.net.ssl.HttpsURLConnection .
我在尝试使用 javax.net.ssl.HttpsURLConnection 连接到 url 时收到“java.lang.ClassCastException”。
I am using Weblogic Server 10.3.4.
我正在使用 Weblogic Server 10.3.4。

I got the solution finally. If we are using Weblogic server, we must define:
我终于得到了解决方案。如果我们使用 Weblogic 服务器，我们必须定义：
set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true
set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true
...in the class path inside the Server Domain.
...在服务器域内的类路径中。
This will tell the weblogic server to use the Sun Http Handlers and not install its own.
这将告诉 weblogic 服务器使用 Sun Http 处理程序而不是安装它自己的。

More detail on @KmrGtm solution:
有关@KmrGtm 解决方案的更多详细信息：
Only thing to do is updating WebLogic domain settings in the setDomainEnv script file.
唯一要做的就是更新 setDomainEnv 脚本文件中的 WebLogic 域设置。
The relevant settings are in the setDomainEnv script file (setDomainEnv.cmd for Windows and setDomainEnv.sh for Linux).
相关设置位于 setDomainEnv 脚本文件（Windows 的 setDomainEnv.cmd 和 Linux 的 setDomainEnv.sh）中。
The file is located in the bin subdirectory of the domain directory (/user_projects/domains//bin/) where:
该文件位于域目录 (/user_projects/domains//bin/) 的 bin 子目录中，其中：
- is the directory where you installed WebLogic.
- is the name of the domain where you are installing Studio.
- 是您安装 WebLogic 的目录。
- 是您安装 Studio 的域的名称。
In the file add the JAVA_OPTIONS argument close to the top of the file:
在文件中靠近文件顶部的位置添加 JAVA_OPTIONS 参数：
- For setDomainEnv.cmd (Windows):
- 对于 setDomainEnv.cmd (Windows)：
set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true
设置 JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true
- For setDomainEnv.sh (Linux):
- 对于 setDomainEnv.sh (Linux)：
JAVA_OPTIONS="%JAVA_OPTIONS% -DUseSunHttpHandler=true"
JAVA_OPTIONS="%JAVA_OPTIONS% -DUseSunHttpHandler=true"
export JAVA_OPTIONS
导出 JAVA_OPTIONS

You also may explicitly define protocol handler. Just create URL using another constructor.
您还可以明确定义协议处理程序。只需使用另一个构造函数创建 URL。
URL url = new URL(null, urlstr, new sun.net.www.protocol.http.Handler());
or
或者
URL url = new URL(null, urlstr, new sun.net.www.protocol.https.Handler());
And it will make the code independent from -DUseSunHttpHandleroption.
它将使代码独立于-DUseSunHttpHandler选项。
