[Axiom] qustion about OMDataSource Class

[Amila Suriarachchi]

I have two questions regarding OMDataSource class
1. OMDataSource class has three serialize method. when each three methods
called by the axiom when it uses with the Axis2.

2. two serailize methods has the following method signature.
     void serialize(java.io.OutputStream outputStream,
org.apache.axiom.om.OMOutputFormat omOutputFormat) throws
javax.xml.stream.XMLStreamException;

    void serialize(java.io.Writer writer,
org.apache.axiom.om.OMOutputFormatomOutputFormat) throws
javax.xml.stream.XMLStreamException;

one method takes an java.io.OutputStream as an input parameter and throws a
javax.xml.stream.XMLStreamException.
should n't it throws an java.io.IOException since it takes the
java.io.OutputStream

this is the problem I have.
In xml beans there is a method called save. which takes either a
OutputStream or Writer and throws an IOException. So if I use that method
here
I have to catch the IOException and throws a XMLStreamException

try {
                    param.save(outputStream);
                } catch (IOException e) {
                    new XMLStreamException("Problem with saving
document",e);
                }

thanks,
Amila.
