Capturing of IP Address through Java Code

Former Member — Mon, 20 Jan 2014 08:08:16 GMT

Dear All,

I have a situation in my Webdynpro Java Application where I have to capture the IP address of the end user's PC. I use the below code for capturing IP:

IWDRequest req = WDProtocolAdapter.getProtocolAdapter().getRequestObject();

String ipAddress = req.getClientHostName();

The problem is, the code is working perfectly in Quality system, but not in Production system. The IP which is captured in the Production system is the Portal IP itself. Is the problem has to do with some Network settings or the code has to be changed?

Hi Sujai

There was a similar issue faced by me while in ITS.

You have to cross check with internet settings+port+clear histrory and other popins.

Also in the code where URL is provided : Check the path should be proper, not refering to sap logon files present in local drives, so as to make system independent.

Can you please try following code.

You may not get the real client IP if a the client is behind a proxy, you will get the IP of the proxy and not the client. However, the proxy may include the requesting client IP in a special HTTP header.

HttpServletRequest req=(HttpServletRequest)TaskBinder.getcurrentTask().getProtocolAdapter().getRequestObjectInternal().getProtocolRequest();

req.getHeader("X-Forwarded_For);

Thanks,

Hi Sunita,

Thanks for taking time to reply. Can you be more clearer regarding the Internet Settings, port and other popins that needs to be checked?

Hi Patralekha,

Thanks for replying. For using the HttpServletRequest in my WD Java code, I need to add the servlet.jar into my DC right? I'll try that way and comeback.

Hi Patralekha,

Thanks for that helpful link you provided. I was able to do some workarounds by adding servlet.jar as external library to my DC. The below code is what I wrote in my DC:

HttpServletRequest request=(HttpServletRequest)TaskBinder.getCurrentTask().getProtocolAdapter().getRequestObjectInternal().getProtocolRequest();

String ip = request.getHeader("X-Forwarded-For");

messageManager.reportSuccess("X-Forwarded-For: "+ip);
