I'm developing an email sendig web service under Axis/Tomcat. i use javamail. If I convert my email sendig method into web service I always get Server.userException and InvocationTargetException error. It is now clear, that if a web service call is established it can't connect to the mail server on the localhost. Furthermore from the debugging I see that alway different ports are used like 3741.. Could you give me some tips to solve this? regards, nagybaly
