It seems that the javax.activation bundled with Geronimo is not compatible with javax.mail. When using an Eclipse running on a JRE1.5 VM, it is not possible to send emails with Multipart attachments and an exception is generated. When using JRE1.6, the javax.activation included in rt.jar (which is Sun's implementation and is different than the one included with Geronimo) supersedes the Orbit one and mail attachments are working fine. java.lang.NoClassDefFoundError: javax/mail/MessagingException at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Unknown Source) at java.lang.Class.getConstructor0(Unknown Source) at java.lang.Class.newInstance0(Unknown Source) at java.lang.Class.newInstance(Unknown Source) at javax.activation.MailcapCommandMap.createDataContentHandler(MailcapCommandMap.java:470) at javax.activation.DataHandler.getDataContentHandler(DataHandler.java:255) at javax.activation.DataHandler.writeTo(DataHandler.java:76) at javax.mail.internet.MimeMessage.writeTo(MimeMessage.java:1142) at javax.mail.internet.MimeMessage.writeTo(MimeMessage.java:1112) at org.apache.geronimo.javamail.transport.smtp.SMTPTransport.sendData(SMTPTransport.java:1419) at org.apache.geronimo.javamail.transport.smtp.SMTPTransport.sendMessage(SMTPTransport.java:648) at javax.mail.Transport.send(Transport.java:95) at javax.mail.Transport.send(Transport.java:48) at org.eclipse.mylyn.reviews.r4e.mail.smtp.mailVersion.Smtp.createAndSendEmail(Smtp.java:325) at org.eclipse.mylyn.reviews.r4e.mail.smtp.mailVersion.Smtp.sendEmail(Smtp.java:111) at org.eclipse.mylyn.reviews.r4e.mail.smtp.mailVersion.Smtp.createMeetingRequest(Smtp.java:192) at org.eclipse.mylyn.reviews.r4e.ui.internal.utils.MailServicesProxy.sendMeetingRequest(MailServicesProxy.java:1103) at org.eclipse.mylyn.reviews.r4e.ui.internal.commands.SendNotificationHandler$1.runInUIThread(SendNotificationHandler.java:128) at org.eclipse.ui.progress.UIJob$1.run(UIJob.java:95) at org.eclipse.swt.widgets.RunnableLock.run(RunnableLock.java:35) at org.eclipse.swt.widgets.Synchronizer.runAsyncMessages(Synchronizer.java:134) at org.eclipse.swt.widgets.Display.runAsyncMessages(Display.java:4041) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3660) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2640) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2604) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2438) at org.eclipse.ui.internal.Workbench$7.run(Workbench.java:671) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:332) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:664) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:115) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:196) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:369) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:620) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:575) at org.eclipse.equinox.launcher.Main.run(Main.java:1408) at org.eclipse.equinox.launcher.Main.main(Main.java:1384)
Could this be related to the discussion in bug 348155? I'm not sure what the fix would be, here. Any ideas? (If not related to bug 348155)

(If not related to bug > 348155) Yes it seems to be a similar problem, but for a different package. Ideally, the solution would be to bundle the correct javax.activation (i.e. the one found in the 1.6 RT.jar) with Geronimo in Orbit, but I'm not sure if that would not cause other compatibility problems. I'm actually surprised nobody reported that earlier, because it means you basically cannot send any mail attachment when using Geronimo with 1.5 JVM
