public class SyslogInitServlet
extends javax.servlet.http.HttpServlet

A servlet that configures Syslog when its init() method is called. It should be configured in a WebApp by adding the following declaration to the web.xml file for the WebApp:

    <servlet>
      <servlet-name>SyslogInitServlet</servlet-name>
      <description>Syslog Initialization Servlet</description>
      <servlet-class>com.protomatter.syslog.xml.SyslogInitServlet</servlet-class>
      <load-on-startup>1</load-on-startup>
      <init-param>
        <param-name>config.xml</param-name>
        <param-value>/path/to/syslog.xml</param-value>
      </init-param>
      <init-param>
        <param-name>show.config.on.get</param-name>
        <param-value>true</param-value>
      </init-param>
    </servlet>
    <servlet-mapping>
      <servlet-name>SyslogInitServlet</servlet-name>
      <url-pattern>/SyslogInitServlet</url-pattern>
    </servlet-mapping>

  

The config.xml init param is requred and should point to the XML configuration file for Syslog.

If the optional show.config.on.get init param is set to true (the default is false), then when the servlet is hit with a GET request, it will return the current Syslog configuration. Care should be taken when using this option since the syslog configuration file may contain database passwords, etc. It is a good idea to use declarative security to protect this servlet if you are allowing it to display the configuration file.

The <servlet-mapping> tag above is optional. If it is not specified, the servlet will still initialize syslog when the WebApp comes up, but the servlet will not be visible to web browsers. This is generally a good thing.

Also, please note that the Protomatter jar file should be placed in your system CLASSPATH and not just included in the lib directory for your WebApp. This will ensure that Syslog is available inside all software running in your application server.
