Where to place JNDI sections for customer deployment

[Darren]

Hi,

I am running Tomcat 5.5.9 and would like to deploy an application (as  
a war file) to various customers, but I am having trouble finding the  
best place for JNDI lookups.  During development I kept everything  
inside the war file and placed my JNDI entries in $WAR/META-INF/ 
context.xml, but I don't want customers to have to edit the  
context.xml in the war file on their systems.

So, I added the following into $WAR/WEB_INF/web.xml

  <resource-ref>
    <description>DB Connection</description>
    <res-ref-name>jdbc/db</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
  </resource-ref>
  <resource-ref>
    <description>Email Server Settings</description>
    <res-ref-name>bean/email</res-ref-name>
    <res-type>somepackage.EmailServerConfiguration</res-type>
    <res-auth>Container</res-auth>
  </resource-ref>

Now I am unsure where to add the following ....

<Context path="/mycontext" docBase="mycontext"
         crossContext="true" reloadable="true" debug="1">

    <Resource name="jdbc/db" auth="Container"  
type="javax.sql.DataSource"
              maxActive="10" maxIdle="15" maxWait="10000"
              removeAbandoned="true" removeAbandonedTimeout="300"  
logAbandoned="true"
              driverClassName="com.mysql.jdbc.Driver"  
username="user" password="pass"
              url="jdbc:mysql://localhost:3306/db? 
autoReconnect=true" />

    <Resource name="bean/email" auth="Container"
              type="somepackage.EmailServerConfiguration"
              factory="org.apache.naming.factory.BeanFactory"
              host="localhost" port="25" />

</Context>

I tried adding it into $CATALINA/conf/server.xml inside the following  
host definition

<Host name="localhost" appBase="webapps"
       unpackWARs="true" autoDeploy="true"
       xmlValidation="false" xmlNamespaceAware="false">

but this meant the mycontext application was always visible in the  
manager and did not autodeploy when a war file was placed in  
$CATALINA/webapps (undeploy didn't appear to work either).  I tried  
without the Context wrapper and the JNDI lookups failed.

I see when an application is deployed tomcat makes it's own context  
configuration within $CATALINA/conf/Catalina/$HOST/$CONTEXT.xml which  
appears a good place to put the JNDI lookups.  Only problem is this  
file is removed by tomcat when the application is undeployed.

Am sure there must be a standard solution to this, so can anyone tell  
me how it is 'meant' to be done?

Thanks,
Darren
