Handling large amounts of XML data with Web Service

I've developed a web service for accessing some information from an ERP database and returning the data in XML format. At the moment the return type of the public method is a String and I'm using axis on tomcat. This is all working as expected but I would like to know if this kind of configuration would handle a very large xml return or should I set a hard limit on the size and force the client to request the data in multiple sets?
