You need HttpServletRequest#getRemoteAddr().

Thanks for the reply dear BalusC ,Yes but i don't have direct access to the servlet request to call getRemoteAddr(). At least not with what i see-can get through sun studio creator's jsf portlet page.

((HttpServletRequest)FacesContext.getExternalContext() .getRequest()).getRemoteAddr();

Indeed, the HttpServletRequest is just accessible by the ExternalContext as you can see here above =)

I tried this but i get: non static method getExternalContext() cannot be referenced from a static context. Any idea about this, cause i'm a little bit confused?

The right way is: String remoteAddr = ((HttpServletRequest) FacesContext.getCurrentInstance().getExternalContext().getRequest()).getRemoteAddr();

Dear BalusC,It seems working. :) (I dont have right now any other pc on the network to ckeck it, but thanks a lot it seems working fine).

:( Unfortunately it was the javascript i entered behind the button and not the possible solution(String remoteAddr = ((HttpServletRequest)FacesContext.getCurrentInstance().getExternalContext().getRequest()).getRemoteAddr();

)! :) It returns me null. Is there any idea about this?

I place this code inside the custom class: "portletPage1" which extends AbstractPageBean.

Try casting to PortletRequest instead of HttpServletRequest.

Dear BalusC,Your help was valuable. Now it really seems working fine.(Note: Instead of getRemoteAddr(), i used getRemoteUser() cause the first one does not exists for PortletRequest ).Best Regards.
