We just moved from Tomcat 5.5.17 to 5.5.20. Our application uses the JavaMail Session as a resource configured in the server.xml. When sending an email in our application I was getting the following
exception: =20 javax.naming.NamingException: Could not create resource factory instance [Root exception is java.lang.ClassNotFoundException: org.apache.naming.factory.MailSessionFactory] at org.apache.naming.factory.ResourceFactory.getObjectInstance(ResourceFact ory.java:131) at javax.naming.spi.NamingManager.getObjectInstance(Unknown Source) I looked in the naming-factory.jar and could not find the MailSessionFactory class. It existed in 5.5.17 and 5.5.20-alpha, but for some reason it is no longer there. I dropped in the naming-factory.jar file from the 5.5.17 version and it worked. Obviously I can't trust that this won't cause other issues so in the meantime we will revert back to 5.5.17. Any idea why this class is missing or if there is some replacement? Thanks
