How to create header.xml.rel

[btjandra]

I am having problem to create a header.xml.rel file. I am getting an error which I am not sure if I do it correctly.

private RelationshipsPart createHeaderRel()
{
RelationshipsPart rPart = null;
try
{
PartName partName1 = new PartName("/word/_rels/"+"header2.xml.rel");

rPart = new RelationshipsPart(partName1);
Relationships relationships = relOf.createRelationships();
Relationship relationship = relOf.createRelationship();
relationship.setTarget("media/headerImage1");
relationship.setType("http://schemas.openxmlformats.org/officeDocument/2006/relationships/image");
relationship.setId("rId12");

relationships.getRelationship().add(relationship);
rPart.setJaxbElement(relationships);
}
catch(Exception e)
{
e.printStackTrace();
}
return rPart;
}


public Part getHeaderPart(String name) throws Exception
{
RelationshipsPart rPart = createHeaderRel();
PartName partName = new PartName(name);
HeaderPart headerPart = new HeaderPart(partName);
headerPart.setJAXBContext(getMicrosoftJAXBContext());
headerPart.setContentType(
new org.docx4j.openpackaging.contenttype.ContentType(
org.docx4j.openpackaging.contenttype.ContentTypes.EXTENSION_JPG_1));
Hdr hdr = this.getPictureWaterMark();
headerPart.setJaxbElement(hdr);
headerPart.setRelationships(rPart);

return headerPart;

}

Part headerPart2 = testDoc.getHeaderPartForImgWaterMark("/word/header2.xml");
docPart.addTargetPart(headerPart2);


I am getting the following error:

I am not sure if I am doing it right. Could you please help?

Thanks!

Hi Betty

Nearly!

Given HeaderPart headerPart, and the Part headerPart2 you want to add to it, all you need to do is :

Code: Select all

headerPart.addTargetPart(headerPart2)


That will automatically create the .rels part if it doesn't already exist. In other words, you don't need your method createHeaderRel()

The below method in BinaryPartAbstractImage may also be of use to you.

Code: Select all

/**
    * Create an image part from the provided byte array, attach it to the source part
    * (eg the main document part, a header part etc), and return it.
    *
    * @param wordMLPackage
    * @param sourcePart
    * @param bytes
    * @return
    * @throws Exception
    */
   public static BinaryPartAbstractImage createImagePart(WordprocessingMLPackage wordMLPackage,
         Part sourcePart, byte[] bytes)
