Hey
First, as long as the code is not compiled by GWT, GWT has zero effect on
it. So your problem is likely not GWT related.
It's difficult to tell from your error 'The API package 'mail' or call
'Send()' was not found.' - I've never seen a java error like this one
before.
Do you maybe have the mail code inside the package you have specified gwt
to build in your gwt.xml file ? If so, you need to move it to a different
package. eg, com.name.client for gwt code and com.name.server for
server/mail code.
