I am using Tomcat 6.0.18 deployed as web service on Windows XP SP3.
I created additional Host element in conf/server.xml, so I have two
virtual hosts: localhost (default) and janko
<Host name="janko" appBase="itsapps">
<!-- Access log processes all example.
Documentation at: /docs/config/valve.html
-->
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="logs"
prefix="its_access_log." suffix=".txt" pattern="common"
resolveHosts="false"/>
</Host>
I deployed the same web applications in both hosts. The first web
application is main, the other one is hypersonic database as storage for
the web application. The main web application defines access to
hypersonic database as resource.
Then localhost web application points to hypersonic listening on port
9002
<Resource
name="jdbc/profile"
auth="Container"
uniqueResourceName="jdbc/profile"
type="com.atomikos.jdbc.nonxa.NonXADataSourceBean"
factory="org.apache.naming.factory.BeanFactory"
connectionTimeout="30"
poolSize="3"
user="sa"
password=""
driverClassName="org.hsqldb.jdbcDriver"
url="jdbc:hsqldb:hsql://localhost:9002"
/>
Then janko web application points to hypersonic listening on port 9003
<Resource
name="jdbc/profile"
auth="Container"
uniqueResourceName="jdbc/profile"
type="com.atomikos.jdbc.nonxa.NonXADataSourceBean"
factory="org.apache.naming.factory.BeanFactory"
connectionTimeout="30"
poolSize="3"
user="sa"
password=""
driverClassName="org.hsqldb.jdbcDriver"
url="jdbc:hsqldb:hsql://janko:9003"
/>
The deployment descriptors are defined in conf/Catalina/localhost and
conf/Catalina/janko folders. docBase points outside of tomcat_home.
However when accessing both web applications only one data source is
used by both web applications depending which one is used first. It
looks to me that JNDI name jdbc/profile is shared across web
applications.
The application uses log4j for logging. Before both web applications
were deployed under the same context name. The side effect was that both
applications logged to the same file. When I renamed web application on
the janko virtual host, the log4j issue was solved. Looks like the same
log4j class instance was used for applications with the same context
name.
I do not use global resources in server.xml. Resources are defined in
application context file only. Based on documentation resource elements
defined in context is private to that context only.
Thank you in advance for any help,
Jan
