GWT: How to extract a content of a javascript function using (JSNI) -

-

i calling javascript function gwt client side using jsni follow:

anchor.addclickhandler(new clickhandler() {             public void onclick(clickevent event) {                execute(notification.getactioncode(), notification.getparams());             } });  private static native string execute(string functionname, string params)/*-{         try{            $wnd[functionname](params);         }catch(e){             alert(e.message);         } }-*/;

my problem javascript function contains window.open("servletname?...."). when clicking on anchor, window opened error below: the requested resource (/es/gwt/core/servletname) not available.

if replace window.open("servletname?....") window.open("../../servletname?...."), window open successfully, these javascript functions used outside gwt cant modify .

i dont know why part /gwt/core being added url causing problem. there way in gwt before executing javascript function, extract content , adding "../.." before url? i mean heaving javascript function name, can content before calling execute function? in case javascript function follow:

function everlinked_addspace(spaceid){         window.open('elutilities?service=space&action=homepage&spaceid='+spaceid+'&template=apps/everlinked/templates/spaces/space_main.htm','_blank');;     }

i need modify in gwt client side , call new modifications.

i appreciate if me.

i think trying resolve problem using bad approach.

the easier way use url re-writer, or modify web.xml url-pattern route relative path sent gwt app same servlet.

probably have in web.xml this:

<servlet>     <servlet-name>myservlet</servlet-name>     <servlet-class>maynamespace.servletname</servlet-class> </servlet> <servlet-mapping>     <servlet-name>myservlet</servlet-name>     <url-pattern>/servletname</url-pattern> </servlet-mapping>

so can add block web.xml. 

<servlet-mapping>     <servlet-name>myservlet</servlet-name>     <url-pattern>/es/gwt/core/servletname</url-pattern> </servlet-mapping>

note url-pattern has limited set of regular expressions (/path/* , *.ext), in case have write full path.

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
