- 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()
