java - Primefaces Chat Application - web.xml Invalid content was found starting with element -

-

this question has answer here:

i want implement pf 3.5 chat application on tomcat 7 server. have added dependencies:

<dependency>     <groupid>org.atmosphere</groupid>     <artifactid>atmosphere-runtime</artifactid>     <version>1.0.1</version> </dependency>  <dependency>     <groupid>org.slf4j</groupid>     <artifactid>slf4j-api</artifactid>     <version>1.7.1</version> </dependency>  <dependency>     <groupid>org.slf4j</groupid>     <artifactid>slf4j-simple</artifactid>     <version>1.7.1</version> </dependency>

however, when implement web.xml:

<web-app xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"     xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"     xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"     version="2.5">

<servlet>     <servlet-name>push servlet</servlet-name>     <servlet-class>org.primefaces.push.pushservlet</servlet-class>     <load-on-startup>1</load-on-startup>     <init-param>         <param-name>org.atmosphere.cpr.broadcastercacheclass</param-name>         <param-value>org.atmosphere.cache.headerbroadcastercache</param-value>     </init-param>     <init-param>         <param-name>org.atmosphere.cpr.broadcasterclass</param-name>         <param-value>org.atmosphere.cpr.defaultbroadcaster</param-value>     </init-param>     <init-param>         <param-name>org.atmosphere.cpr.broadcastfilterclasses</param-name>         <param-value>org.atmosphere.client.trackmessagesizefilter</param-value>     </init-param>     <init-param>         <param-name>org.atmosphere.cpr.sessionsupport</param-name>         <param-value>true</param-value>     </init-param> </servlet> <servlet-mapping>     <servlet-name>push servlet</servlet-name>     <url-pattern>/primepush/*</url-pattern> </servlet-mapping>

as excpetion get:

cvc-complex-type.2.4.a: invalid content found starting element 'init-param'. 1 of '{"http://java.sun.com/  xml/ns/javaee":run-as, "http://java.sun.com/xml/ns/javaee":security-role-ref}' expected.

btw exception @ <init-param> tag.

i appreciate answer!

update

i same excpetion when write that:

<servlet>     <servlet-name>push servlet</servlet-name>     <servlet-class>org.primefaces.push.pushservlet</servlet-class>     <load-on-startup>1</load-on-startup>     <init-param>         <param-name>channels</param-name>         <param-value>chat,counter</param-value>     </init-param> </servlet>  <servlet-mapping>     <servlet-name>push servlet</servlet-name>     <url-pattern>/prime-push/*</url-pattern> </servlet-mapping>

i expcetion @ <init-param> tag

according schema order matters. <load-on-startup/> element should come after <init-param/> element.

eg.

<servlet>     <servlet-name>push servlet</servlet-name>     <servlet-class>org.primefaces.push.pushservlet</servlet-class>     <init-param>         <param-name>channels</param-name>         <param-value>chat,counter</param-value>     </init-param>     <load-on-startup>1</load-on-startup> </servlet>

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
