Log servlet

Log servlet 1.6

It is a Java servlet allows you to collect information about page visitors. You can put a reference to this servlet inside your pages and all relevant information will be collected in the given log file. And the reference to this servlet looks like a graphical dot on your page.

How to use it:

a) copy logPackage.jar into your WEB-INF/lib directory.

b) define LogServlet in your web.xml file:

    <servlet>
     <servlet-name>LogServlet</servlet-name>
     <servlet-class>com.jsos.log.LogServlet</servlet-class>
    </servlet>

c) define a mapping:

    <servlet-mapping>
     <servlet-name>LogServlet</servlet-name>
     <url-pattern>/servlet/LogServlet</url-pattern>
    </servlet-mapping>

You may use this servlet in one of two forms. At the first hand you may set a path to your log file as a parameter to this servlet. So the usage (html code for your page) is:

or you can set a path to some directory. Log file (files) will be created within this directory automatically. File name will be selected according to the template: ddmmyyyy.txt where dd is current day, mm is current month and yyyy is current year:

also you can define log file (directory) as an initial parameter for this servlet. Parameter name is log:

    <servlet>
     <servlet-name>LogServlet</servlet-name>
     <servlet-class>com.jsos.log.LogServlet</servlet-class>
     <init-param>
      <param-name>log</param-name>
      <param-value>path_to_log_file</param-value>
     </init-param>
    </servlet>

in this case you can use servlet so:

Log file is a text file with tab separated values. Each line contains:
IP address, date,visitor's browser,referer page,visitor's charset,visitor's encoding,visitor's language (locale).
