MessagingException

Question

I'm annoyed because I have this Exception with occured within my HTML page when I'm using it out of Jbuilder.
While I'm using the HTML page (generated in Jbuilder) in Jbuider I don't have any problem and my mail is sent, but not when I'm using it outside of the Jbuilder soft....
Here is the Message I get:
java.lang.ClassNotFoundException: javax.mail.MessagingException
     at com/ms/vm/loader/URLClassLoader.loadClass
     at java/lang/ClassLoader.loadClassInternal
     at newholiday/Applet1.buttonEnvoi_mouseClicked

Could somebody help me please???

Answer 1

Look again. The message you get is not MessagingException, but java.lang.ClassNotFoundException. And that's the usual problem, JVM can't find that class because it isn't in the classpath. But it appears you are using an applet. So you will have to make sure that mail.jar and activation.jar are accessible via its codebase parameter.
