XML serializer problem

Question

I am trying to use an XML serializer to get an XML file place in an exist database and store it to the hard drive as an XML file.
my code in order to do that is
XMLResource documentbef = (XMLResource)r;
doc2=(Document) documentbef.getContentAsDOM();
doc2.normalize();
OutputFormat format = new OutputFormat(doc2);
format.setIndenting(true);
XMLSerializer serializer = new XMLSerializer(new FileOutputStream(new File("C:\\Configuration\\XmlRoomCopy.xml")), format);
serializer.serialize(doc2); i have included the needed jar files, and did the imports. but i get the following errors
symbol  : constructor OutputFormat(org.w3c.dom.Document)
location: class org.apache.xerces.domx.XGrammarWriter.OutputFormatand
symbol  : method setIndenting(boolean)
location: class org.apache.xerces.domx.XGrammarWriter.OutputFormat
format.setIndenting(true);
symbol  : constructor XMLSerializer(java.io.FileOutputStream,org.apache.xerces.domx.XGrammarWriter.OutputFormat)
location: class org.apache.xml.serialize.XMLSerializer
XMLSerializer serializer = new XMLSerializer(new FileOutputStream(new File("C:\\Configuration\\XmlRoomCopy.xml")), format);i'm new at this so I could have done the dumbest mistake.
thank you

Hi.
Check this:
drop type msm force;
drop type list_msm force;
create type msm as object(
nume VARchar2(20)     --VARCHAR2 NOT CHAR
create type list_msm as table of msm;
create table produse
den char(20)
INSERT INTO produse VALUES('Prod.1');
INSERT INTO produse VALUES('Prod.2');
INSERT INTO produse VALUES('Prod.3');
COMMIT;
select xmlserialize (document xmlelement("values",
cast(multiset(
select trim(p.den) from produse p) as list_msm
) as clob indent size=2
) as "xml"
from dual;
<values>
  <LIST_MSM>
    <MSM>
      <NUME>Prod.1</NUME>
    </MSM>
    <MSM>
      <NUME>Prod.2</NUME>
    </MSM>
    <MSM>
      <NUME>Prod.3</NUME>
    </MSM>
  </LIST_MSM>
</values>Hope this helps.
