Jerry Messenger Server has two configuration files:

  • /conf/jerry.xml 
  • /conf/jetty.xml

Below is an example of jerry.xml configuration file. The highlighted values are the fields which you most likely need to tune up.

Jerry Messenger uses embedded Jetty web server. The value which you most likely want to set up in the  jetty.xml is the port number:

<Call name="addConnector">
          <New class="">
            <Set name="port">8080</Set>
            <Set name="maxIdleTime">50000</Set>
            <Set name="lowResourceMaxIdleTime">1500</Set>

For detailed information about jetty.xml see Jetty documentation.  

Note: All of the information in the configuration files is read at startup, so any change to the files necessitates a restart of the server.


Running the Jerry Messenger Server

Running Jerry Messenger Server is as simple as going to /bin directory and running: (Linux/Unix)
startup.bat (Windows)

This will start the server. On a web page at: http://localhost:8080/infoPage you will see a list of all accounts defined in jerry.xml.
Also you may get a HTML code for WEB chat to insert into your web site.

Note:  JAVA_HOME environment variable should  point at your Java installation in order to start the server.

Jerry Messenger uses database in /db directory. The all operator related information is stored in this database. To clean up the database, just remove the all files in /db directory. A new database will be created automatically during  Jerry Messenger start.

To stop the server, run:  (Linux/Unix)
shutdown.bat (Windows)


Set up a Web Chat on your Web Site

The http://localhost:8080/infoPage has a list of all accounts defined in jerry.xml configuration file. On this page there is a HTML code which you need to cut-and-paste into your web site page. This code is generated automatically depending on your Jerry Messenger account settings.

Note: If you made changes in the presence image size, you had to update the HTML code on your web site.


Client (Operator Program) Installation

Jerry Messenger uses standard Jabber/XMPP protocol, so you may use any of the hundreds Jabber Clients. The following screenshots were taken from different Jabber Client programs. You may use them as example to configure your client program.

Note: The operators' Jabber ID and password should be the same as in your jerry.xml configuration file in <operator ... />.
