Can we get Remote IP Address without using HttpServletRequest?

[Koti Samadhi]

Hi All,

Can we get Remote IP Address without using HttpServletRequest?

I have the solution like below:

public void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
InetAddress remoteInetAddress = InetAddress.getByName(req.getRemoteAddr());

}

Could you please provide me any alternate solution with out using HttpServletRequest ?

Thanks & Regards
Koti

How? The request is the *only* information you have from the client, no?

David is totally right , but the question here is why you wanna get Remote IP Address without using HttpServletRequest? !!

[jay vas]

The following code results in the output shown in comments.....

		String ss = a.getRequest().getRemoteUser()+"/"+a.getRequest().getRemoteAddr()+"/"+a.getRequest().getRemoteHost();


// The output of ss is now equal to 'null/0:0:0:0:0:0:0:1%0/0:0:0:0:0:0:0:1%0' ...

Thus none of these methods have useable information.

How can I get a real IP address Gets no useable data.... Why ? I need the users ip address for logging purposes... And I recall the "getRemoteAddr())" method as working.

In Tomcat server.xml there is an "enableLookups" setting - set this to true and see what happens.

The comments in server.xml explain it all.
