Hi, I am very interesting in this subject: How to work it out using these files? (1)config\global-web-application.xml (2)config\mime.types If I change the items of mime.types, need I restart the orion server to retrieve latest mimetype items? If I hope to keep the mime.types under application level, which location should I put my own mime.types? which META-INF? I am developing a MailSender(a session bean) and want to know the attachments' MIME type using javax.activation.MimetypesFileTypeMap. I am appreciate it if you send me the answer! Best regards!
