Subject SEVERE: Error listenerStart -- without entering the listener
Date Wed, 06 Aug 2008 15:39:04 GMT
Hi all,

Using: Mac OS X 10.4.5 running Tomcat 5.5.26 -- this is a brand-new  
copy downloaded from Apache & unzipped; no changes.

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:
