Checking Weblogic version

To check Weblogic version go to WL_HOME/server/bin and run setWLSEnv.sh
Next run java weblogic.version

#java weblogic.version

WebLogic Server 10.3.6.0  Tue Nov 15 08:52:36 PST 2011 1441050

Use 'weblogic.version -verbose' to get subsystem information

Use 'weblogic.utils.Versions' to get version information for all modules

In Windows open cmd, go to WL_HOME\server\bin and run setWLSEnv.cmd

How to resolve: java.lang.ClassCastException: weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection

Hi. Today I will share easy recipe to resolve following error:

<org.jsfportal.shiro.FacebookRealm> <FacebookRealm> <doGetAuthenticationInfo> <Throwable: weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection> 
java.lang.ClassCastException: weblogic.net.http.SOAPHttpsURLConnection cannot be cast to javax.net.ssl.HttpsURLConnection

The error can occur only when you deployed your appplication to the Weblogic Server and you try to run following (or simillar) code:

URL url;
url = new URL("https://yoururl.com");
HttpsURLConnection con = (HttpsURLConnection)url.openConnection();

There are two (or maybe more) ways to bypass this problem.
  1. Fix your code. You can create URL object in a following way:
    url = new URL(null,"https://yoururl.com",new sun.net.www.protocol.https.Handler());
  2. Using a more "general" solution you can force the usage of the Sun Http Handlers instead of the Weblogic specific. To do this you should add java option: -DUseSunHttpHandler in startWeblogic.sh or startWeblogic.cmd:
    set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true
