Re: [Carbon-dev] Loader constraint violation error when calling DataHandler objects in jsp
We have fixed the JSP class loading issues some time ago. Please check
whether javax.activation.* package is duplicated in somewhere
Thanks,

Re: [Carbon-dev] Loader constraint violation error when calling DataHandler objects in jsp
JSPs are loaded from a separate classloader. The workaround for this is to
put your code into a Java class and call that from the JSP. We need to
properly fix this though; wherever we have duplicated JARs we will see such
problems.
