XML returned from the server does not have 'root' element

I have developed an application using MySQL and then on another server used Derby in a Cloud/VM environment. In one form of many I get the message

It still works fine with the MySQL copy.

The form is creating a new record and is wizard style.

I have tried removing any text and searched for & on its own. I removed all html with & but the error still occurs

Help please

Turned out to be a truncation problem - one of the attributes had insifficient length.

For everyone - if you have any problem, first look at the Aware IM Server and Tomcat output!
