Its very simple ,for the testing you want to import "java.net.InetAddress" package

//Get an instance of InetAddress for the local computer
InetAddress inetAddress = InetAddress.getLocalHost();

//Get a string representation of the ip address
String ipAddress = inetAddress.getHostAddress();

//Print the ip address
System.out.println(ipAddress);

These specifications define a behavior model for web services. Proxy service security requirements are different from each others. WSO2 ESB providing pre-define commonly used twenty security scenarios to choose based on the security requirements. This functionality is provided by the security management feature which is bundled by default in service management feature in ESB. This configuration can be done via the web console until ESB 4.8.1 release, but this has been removed from the ESB 4.9.0. Even though this feature isn't provided by the ESB web console itself same functionality can be achieved by the new WSO2 Dev Studio . WSO2 always motivate to use dev studio to prepare required artifacts to the ESB rather than the web console. Better way to explain this scenario is by example. Following

Passthru transporter – support header fields               Location Keep-Alive Content-Length Content-Type Date Server User-Agent Host Nhttp transport – support headers Server User-Agent Date You can specify header fields which should be preserved in a comma-separated list, as shown below. http.headers.preserve = Location, Date, Server Note that
