This is a sample client code that generates a partial xml file using Apache SIS that conforms to ISO 19115 schema:

package edu.unr.nccp;
 
 
import org.apache.sis.internal.jaxb.gmi.MI_Metadata;
import org.apache.sis.metadata.iso.citation.DefaultContact;
import org.apache.sis.metadata.iso.citation.DefaultResponsibleParty;
import org.opengis.metadata.Metadata;
import org.opengis.metadata.citation.Contact;
import org.opengis.metadata.identification.CharacterSet;
import org.opengis.metadata.maintenance.ScopeCode;
 
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
import java.util.Locale;
 
public class GenerateMetadataXml {
  public static void main(String[] args) {
    MI_Metadata mi_Metadata = new MI_Metadata();
    mi_Metadata.setLanguage(Locale.ENGLISH);
    mi_Metadata.setCharacterSet(CharacterSet.UTF_8);
    List scopeCodes = new ArrayList<ScopeCode>();
    scopeCodes.add(ScopeCode.DATASET);
    mi_Metadata.setHierarchyLevels(scopeCodes);
     
    try {
     
      File file = new File("file.xml");
      JAXBContext jaxbContext = JAXBContext.newInstance(MI_Metadata.class);
      Marshaller jaxbMarshaller = jaxbContext.createMarshaller();
      jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
      jaxbMarshaller.marshal(mi_Metadata, file);
      
    } 
    catch (JAXBException e) {
    
    }
  }
}

This is the xml output the above client code produces:
