Each listener should be in it's own <listener> ... </listener> element
block. Don't try to put all three in one.

Hi all,

This project used to work; I'm trying to figure out what got broken.
Symptom: listenerStart fails without even getting to the first line
of the AppListener (catalina.out trace below).
From web.xml:
<web-app>
<listener>
<listener-class>com.connectedtrading.listener.AppListener</listener-class>
<listener-class>com.connectedtrading.database.HibernateListener</listener-class>
<listener-class>com.connectedtrading.listener.SessionListener</listener-class>
</listener>
.......
I've tried swapping the first two lines; neither works anymore.
Both listener classes are present in WEB-INF/classes.
My application context.xml is in META-INF:
<Context path="" debug="5" reloadable="true" crossContext="true">
<Resource name="jdbc/ct_alerts" auth="Container"
type="javax.sql.DataSource"
maxActive="100" maxIdle="30" maxWait="10000"
username="xxxxx" password="xxxxx"
driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/ct_alerts"
validationQuery="select 1"
/>
</Context>
I've dropped raw println's at the beginning of the listeners, e.g.:
public void contextInitialized(ServletContextEvent
servletContextEvent)
{
System.out.println("++++++++++++++++++");
.......
But as you can see from the catalina.out trace below, these are not
being executed.
To eliminate possible permission problems, I've made the entire app
tree in webapps
universally read-write-executable (anyway, it's all owned by me and
tomcat is running
as me -- started both from startup.sh or from Eclipse).
Any thoughts or pointers about working this out will be greatly
appreciated:
Here's the startup trace from catalina.out:
