I love these new Forums. No replies. Thank goodness for Google.
 
I've found the problem. My config was OK. The problem is a Tomcat Bug. Anybody else trying to use the email element with CVP 7.0(2) is going to have problems. There is a bug in Tomcat 5.5(20) and later; (23) is shipped with CVP 7.0. See https://issues.apache.org/bugzilla/show_bug.cgi?id=40668
The Mail Session class files are NOT present in the naming-factory.jar file after 5.5(17).
To fix the issue you need to download the 5.5(17) version http://archive.apache.org/dist/tomcat/tomcat-5/v5.5.17/bin/apache-tomcat-5.5.17.zip and copy the 'naming-session.jar' file to the Tomcat/common/lib file. You will need to stop tomcat and rename the old file first.
 
Cheers

OK but excuse my poor programing knowledge and skills.
There are two ways to configure the Resources. The first is to define them in the server.xml as <GlobalNamingResources> and then include 'Resource Links' in the Context.xml file or, just define the 'Resource names' in the Context.xml file and not touch the server.xml file. This later method seems to be what is now recommended for Tomcat 5.5. I have an open question on this discussion forum to try to determine which method should be used and what the pros and cons of each are. Been no takers as yet though.
 
So, as an example. defining both a MySQL database and an email JNDI.
1st Method (Defining Global Naming Resources and Resource Links)
 
Server.xml
 
<!-- Global JNDI resources -->
  <GlobalNamingResources>
 
   <Resource name="jdbc/TestDB"
     auth="Container"
     type="javax.sql.DataSource"
     factory="org.apache.tomcat.dbcp.dbcp.BasicDataSourceFactory"
     driverClassName="com.mysql.jdbc.Driver"
     url="jdbc:mysql://localhost:3306/accttest1?autoReconnect=true"
     username="bruce"
     password="bruce"
     maxActive="20"
     maxIdle="10"
     poolPreparedStatements="true"/>
 
   <Resource name="mail/TestMail"
     auth="Container"
     type="javax.mail.Session"
     mail.smtp.host="your SMTP Server"/>
 
  </GlobalNamingResources>
 
Context.xml
 
<!-- The contents of this file will be loaded for each web application -->
<Context>
    <!-- Default set of monitored resources -->
    <WatchedResource>WEB-INF/web.xml</WatchedResource>
           <Manager pathname="" />
 
  <ResourceLink global="jdbc/TestDB" name="jdbc/TestDB" type="javax.sql.DataSource"/>
 
  <ResourceLink global="mail/TestMail" name="mail/TestMail" type="javax.mail.Session"/>             
</Context>
 
2nd method (Just defining the resource names in the Context.xml file
 
<Context>
<Resource name="jdbc/TestDB" auth="Container" type="javax.sql.DataSource"
          maxActive="100" maxIdle="30" maxWait="10000"
          username="bruce" password="bruce" driverClassName="com.mysql.jdbc.Driver"
          url="jdbc:mysql://localhost:3306/accttest1?autoReconnect=true"/>
 
<Resource name="mail/TestMail" auth="Container" type="javax.mail.Session"                                  
          mail.smtp.host="your SMTP server"/>
 
</Context>
 
Thanks

I'd like to note that this error still exists in CVP 8.5. The download link Bruce provided has the proper naming-factory.jar in it.
