Hi guys,

    I have a Web application that is running on my JBOSS server. I use spring 3.0.3 and JBOSS 4.2.3.GA. There is a RPC call that sends e-mails to a user. When I test it in my local machine it works fine, but when I try to send an e-mail after the deploy I get this erro:

 ERROR [[/webapp]] Exception while dispatching incoming RPC call
com.google.gwt.user.server.rpc.UnexpectedException: Service method 'public abstract java.lang.String 
com.webapp.client.rpc.EnviarEmailServiceRpc.enviarEmail(com.webapp.model.Regra,com.webapp.model.Usuario,
