Package org.logicalcobwebs.proxool.configuration

Class ServletConfigurator

  • All Implemented Interfaces:
    java.io.Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig
    public class ServletConfigurator
extends javax.servlet.http.HttpServlet

    Allows you to configure Proxool using a servlet. There are three different ways: The init parameters can either directly configure Proxool (in a similar fashion to the PropertyConfigurator) or they can point to separate XML or property files. For example:

    1. XML file delegates to JAXPConfigurator passing in the filename. If the filename is not absolute then it is prepended with the application directory.

        <servlet>
        <servlet-name>ServletConfigurator</servlet-name>
        <servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>
        <init-param>
            <param-name>xmlFile</param-name>
            <param-value>WEB-INF/proxool.xml</param-value>
        </init-param>
    </servlet>
    2. Property file delegates to PropertyConfigurator passing in the filename. If the filename is not absolute then it is prepended with the application directory. 
        <servlet>
        <servlet-name>ServletConfigurator</servlet-name>
        <servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>
        <init-param>
            <param-name>propertyFile</param-name>
            <param-value>WEB-INF/proxool.properties</param-value>
        </init-param>
    </servlet>
    3. Init parameters delegates to PropertyConfigurator by passing in a new Properties object based on the servlet's init parameters. 
        <servlet>
        <servlet-name>ServletConfigurator</servlet-name>
        <servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>
        <init-param>
            <param-name>jdbc-0.proxool.alias</param-name>
            <param-value>test</param-value>
        </init-param>
        <init-param>
            <param-name>jdbc-0.proxool.driver-url</param-name>
            <param-value>jdbc:hsqldb:.</param-value>
        </init-param>
        <init-param>
            <param-name>jdbc-0.proxool.driver-class</param-name>
            <param-value>org.hsqldb.jdbcDriver</param-value>
        </init-param>
    </servlet>

    It will also automatically shutdown Proxool. See destroy().
