You can use      marshaller setProperty  jaxb fragment   Boolean TRUE    It works for me on Java 8

in JAXB that is part of JDK1 6 marshaller setProperty Marshaller JAXB FRAGMENT  true

If you make document dependent on DOCTYPE  e g  use named entities  then it will stop being standalone  thus standalone  yes  won t be allowed in XML declaration   However standalone XML can be used anywhere  while non-standalone is problematic for XML parsers that don t load externals    I don t see how this declaration could be a problem  other than for interoperability with software that doesn t support XML  but some horrible regex soup

If you are using only the default javax xml package  you could set the JAXB FRAGMENT option of the marshaller to  true   this omits the default xml processing instruction  and use the writeProcessingInstruction method of the XMLStreamWriter to insert your own   xmlStreamWriter writeProcessingInstruction  xml    version   1 0   encoding   UTF-8      jaxbMarshaller setProperty  Marshaller JAXB FRAGMENT  Boolean TRUE   jaxbMarshaller marshal object  xmlStreamWriter   xmlStreamWriter writeEndDocument

You can either use marshaller setProperty Marshaller JAXB FRAGMENT  true    or marshaller setProperty  quot com sun xml bind xmlDeclaration quot   false   to disable the default XML declaration  and then add your custom XML declaration   lt  xml version  quot 1 0 quot  encoding  quot UTF-8 quot   gt   by marshaller setProperty  quot com sun xml bind xmlHeaders quot          quot  lt  xml version   quot 1 0  quot  encoding   quot UTF-8  quot   gt  quot     to the generated xml  thus avoiding the standalone  quot yes quot  property
