Subject Re: Attachements and .Net: The datatype 'DataHandler' is missing
Date Tue, 04 Jan 2005 19:57:08 GMT
I was also having the same exact problem (except that my input argument to 
one of the methods is DataHandler).

I searched the previous mails on this topic and no one seems to have 
suggested a good answer. Atleast I could find out that using DataHandler is 
not a good solutions if you want to support non-java application. But whats 
the best solution for this?
