Summary: ServletContextListener Notified Multiple Times When
Using Virtual Hosting
Product: Tomcat 5
Version: 5.5.12
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: kevin.l.janise@accenture.com
The ServletContextListener is getting notified multiple times when virtual
hosting is used.
I created an app and deployed it under the Tomcat 5.5.15\webapps directory
where it worked as expected.
I then deployed the same app using virtual hosting and found that the
ServletContextListener is notified 2 times. If I put a static counter variable
in it the variable does not get incremented.
A Singleton registry object I created shows that items are getting registered
into it 2 times, I'm logging when items are registered in it. But no exception
is generated. I throw an exception if objects are being bound using the same
name. It seems there are 2 of them in existence.
Here is the entry I'm using in the server.xml file to set up the virtual
hosting.
<Host name="test.struts"
appBase="C:/Data/Projects/test"
unpackWARs="true"
autoDeploy="true"
xmlValidation="false"
xmlNamespaceAware="false">
<Alias>www.test.struts</Alias>
<Context path="" docBase="test.struts" reloadable="true" debug="0">
<Resource
name="jdbc/test"
type="javax.sql.DataSource"
password="password"
driverClassName="com.mysql.jdbc.Driver"
maxIdle="2"
maxWait="5000"
validationQuery="SELECT 1"
username="root"
url="jdbc:mysql://localhost:3306/test"
maxActive="4"/>
</Context>
</Host>
I also get the same behavior under the 5.5.15 version. That wasn't an
available option I could select when filling in the report.

5.5.15 is an available option now, so I'm updating the version.
I wonder if each Host (virtual or not) gets its own classloader: that would
explain the behavior you're seeing. To confirm that hunch, to something like
System.out.println(getClass().getClassloader().toString()) from your Listener.
And if that hunch is confirmed, and you truly want a single object across
multiple classloaders, put that object in a different repository (e.g.
common/lib instead of WEB-INF/lib).
