That's not a problem, I successfully created a class which extends
- Code: Select all
JaxbSmlPart<CTComments>
The code I'm using is :
- Code: Select all
Parts parts = pkg.getParts();
Part workSheet = parts.get( new PartName( "/xl/worksheets/sheet1.xml") );
RelationshipsPart wsRP = workSheet.getRelationshipsPart();
if( wsRP == null ){
wsRP = new RelationshipsPart();
workSheet.setRelationships( wsRP );
}
comments.setRelationshipType( "http://schema.openxmlformats.org/officeDocument/2006/relationships/comments" );
ContentTypeManager ctm = pkg.getContentTypeManager();
CTOverride ctOv = new CTOverride();
ctOv.setContentType( "application/vnd.openxmlformats-officedocument.spreadsheetml.comments+xml" );
ctOv.setPartName( "/xl/comments.xml" );
URI uRI = null;
try
{
uRI = new URI("/xl/comments.xml");
}
catch (URISyntaxException e)
{
e.printStackTrace(); //To change body of catch statement use File | Settings | File Templates.
}
ctm.addOverrideContentType( uRI, ctOv);
Relationship rel = wsRP.addPart( comments, true, ctm ); // This is throwing the Null Pointer Exception
workSheet.addTargetPart( comments );
comments is an instance of my subclass of JaxbSmlPart<CTComments> (which just has the constuctor which takes a PartName).
The error I get is :
- Code: Select all
JAXB: Using Java 6 implementation.

I'm obviously missing something related to relationships but I'm not sure what. Could you please give me some pointers as to what to add or do differently?
