It is ok now. Thanks Amish Mehta from

jwchat can now be used through both apache(http://localhost) and openfire jetty (http://localhost:8080/jwchat/index.html)

Following is the relative complete configuration. And my software version is jwchat 1.0 beta3 + openfire 3.3.3

1   config the  httpd.conf file of apache

LoadModule proxy_module modules/mod_proxy.so

LoadModule proxy_http_module modules/mod_proxy_http.so

<VirtualHost *>

ServerName localhost

DocumentRoot /var/www/jwchat

<Directory /var/www/jwchat>

Options  +MultiViews

</Directory>

AddDefaultCharset UTF-8

ProxyPass /http-bind/ http://127.0.0.1:8080/http-bind/[http://127.0.0.1:8080/http-bind/]

</VirtualHost>

2 

Open config.js and comment all BACKENDS except 'Native Binding'

3   Edit jsjac.js and set

var JSJACHBC_USE_BOSH_VER  = false; /* true; */

4 

Edit jwchat.html and just before line:

con.connect(oArg);

Add this line:

oArg.authtype = 'nonsasl';

5  

Log into OpenFire as an administrator and add two server properties:

xmpp.httpbind.client.requests.polling = 0

xmpp.httpbind.client.requests.wait = 10

6    restart openfire and apache,then login through http://localhost

it is ok
