You could create a SetupServlet (that instantiates objects and stores them
in Application context) which is initialised by the container at startup.
You'd declare this requirement and pass parameters to the servlet (EJB
compliant setter methods are required) via the web.xml file. In web.xml
you'd have something like this:
<servlet>
<servlet-name>setup</servlet-name>
<servlet-class>au.com.nationalmortgage.alladin.servlets.SetupServlet</servle
t-class>
<init-param>
<param-name>driverMSQL</param-name>
<param-value>com.merant.datadirect.jdbc.sqlserver.SQLServerDriver</param-val
ue>
</init-param>
<init-param>
<param-name>serverMSQL</param-name>
<param-value>jdbc:sqlserver://192.168.0.2:1433</param-value>
</init-param>
<init-param>
<param-name>logFileMSQL</param-name>
<param-value>/home/virtual/domains/somewhere.com/www/WEB-INF/logs/brokerMSQL
.log</param-value>
</init-param>
<init-param>
<param-name>loginMSQL</param-name>
<param-value>www</param-value>
</init-param>
<init-param>
<param-name>passwordMSQL</param-name>
<param-value>na710nal</param-value>
</init-param>
<init-param>
<param-name>minConnsMSQL</param-name>
<param-value>4</param-value>
</init-param>
<init-param>
<param-name>maxConnsMSQL</param-name>
<param-value>20</param-value>
</init-param>
<init-param>
<param-name>maxConnTimeMSQL</param-name>
<param-value>1</param-value>
</init-param>
<load-on-startup/>
</servlet>
You could alternatively name and instantiate JNDI resources - as in the
Tomcat 4 documentation - I think this is much tidier.
