You can implement a custom adapter that parses your special date format string into a valid date.

package xmlhelper;

import java.text.SimpleDateFormat;
import java.util.Date;

import javax.xml.bind.annotation.adapters.XmlAdapter;

public class DateAdapter extends XmlAdapter<String, Date> {

    private SimpleDateFormat dateFormat = new SimpleDateFormat("dd.MM.yyyy");

    @Override
    public String marshal(Date v) throws Exception {
        return dateFormat.format(v);
    }

    @Override
    public Date unmarshal(String v) throws Exception {
        return dateFormat.parse(v);
    }
}

To use it in your webservice you have to modify the generated webservice source class. Simply add an @XmlJavaTypeAdapter annotation into your method parameter definiton:

  @javax.jws.WebMethod
  @javax.jws.WebResult(name="result")
  public CallResult call(
          @javax.jws.WebParam(name="createJavaDataSaved") 
          @XmlJavaTypeAdapter(DateAdapter.class) 
          java.util.Date createJavaDataSaved)
    throws ch.ivyteam.ivy.webservice.process.restricted.WebServiceProcessTechnicalException
  {
    ...
  }

Remember that the generated webservice source will be overwritten whenever you change the mod file of the webservice. So you should at least write a test against your webservice stub so that you get an early warning if the adapter is not in charge anymore.
