Hi, We faced the same problem as: http://www.mail-archive.com/[EMAIL PROTECTED]/msg48320.html The message reports the exception when sending e-mail. It looks like this:
javax.activation.UnsupportedDataTypeException: no object DCH for MIME type text/plain at javax.mail.Transport.send0(Transport.java:219) We re-produce this, only if we enable SecurityManager and place "mail.jar" and "activation.jar" into: ${catalina.home}/shared/lib SecurityManager seems to prevent "javax.activation.CommandMap" to load: META-INF/mailcap from "mail.jar" To avoid this kind of problem, "catalina.policy" should include the entity like this: grant codeBase "file:${catalina.home}/shared/lib/activation.jar" { permission java.io.FilePermission "/usr/local/jakarta-tomcat-4.1.12-LE-jdk14/shared/lib/mail.jar","read"; }; I request you to add the lines below to "catalina.policy". // If you place "mail.jar" and "activation.jar" into: // ${catalina.home}/shared/lib // please activate the entity below and update the target of // FilePermission. //grant codeBase "file:${catalina.home}/shared/lib/activation.jar" { // permission java.io.FilePermission "/usr/local/jakarta-tomcat-4.1.12-LE-jdk14/shared/lib/mail.jar","read"; //}; I think this will help many Tomcat users, but do no harm. Any suggestion/questions are welcome to me. -- Happy Java programming!
