I search in docx4j forum but didnt find any clear was of doing this .Can someone pls help in this regard .
Thanks in advance !

Hi,

Searching for the same solution .
Is it possible to create header object from one existing word file(.docx) and use that header object part into another .docx file .

[saurabh]

Below is the code i am trying ....pls help whats wrong in this as m getting exception

createHeaderReference(wordMLPackage, relationship);

wordMLPackage.save(new File("C:\\Users\\saurabh\\Desktop\\",

Hi Jason..
this requirement feasible or not with docx4j ???

Hi Jason..
this requirement feasible or not with docx4j ???

Sure, it is straightforward enough, and you were nearly there...

Sorry not to reply sooner, but when I'm busy, I have to prioritize questions/issues based on their significance to the project as a whole.

See modified/working code below, especially the comment I've added which explains the issue you encountered. In summary, when copying a part from an existing docx, you should instead clone its contents.

Rather than extracting a header from an existing docx, it might be better if you just read the XML from a header.xml file stored somewhere?

                        at org.docx4j.openpackaging.io3.stores.ZipPartStore.saveJaxbXmlPart(ZipPartStore.java:242)
                       
                        For processing efficiency, docx4j doesn't actually fully load a part until it is needed.
                       
                        To load it, it needs to know where to find it (ie its SourcePartStore).
                       
                        This info is stored at the package level, so if you move the part to a new package, that info is lost.
                       
                        3 ways to work around this:
                       
                        1. wordprocessingMLPackage.setSourcePartStore(headerPart.getPackage().getSourcePartStore());
                       
                                but not so good, since in the general case, you might want to use several source packages,
                                and, in any case, you can't retrieve the part if you've changed its name
                               
                        2. unmarshall it, so it is fully loaded and docx4j doesn't try to get it from the source part store
               
                                        headerPart.getContents();
                       
                           this works fine, but it is a bit opaque since it relies on a side effect / underlying knowledge of docx4j
                           
                        3. best: clone it
                        */
               
                HeaderPart newHeaderPart = new HeaderPart();
                newHeaderPart.setContents(

                return wordprocessingMLPackage.getMainDocumentPart().addTargetPart(

Hi Jason,

really thanks for your much awaited reply !

there is one issue with the deepCopy method...its not copying the "image" contain in the header footer . So is there any alternative for this or how to resolve ??

also you suggested one solution to " read the header from a header.xml file stored somewhere" ..Can you please tell me how do my client create the header.xml if i ask them to share with me and I will use that header while creating new docx ?
or can we export header of existing docx file in form of xml something ??

[jonaskinny]

Old post, but I too am learning this Awesome API (thank you Jason/Plutex !!) and this is what I have done re: moving a Part from one existing Package (source) to a newly created Package (target). I don't have an image (my case is a SlidePartLayout), but this may help you out. I'm not certain all is complete/correct in the resulting .ppxt does not have everything (like docProps dir that gets created when you use a tool like LibreOffice to create a .pptx etc.) but the resulting .pptx has everything I expect at this point (still learing the api), and it functions without errors.

I'm working on applying the layout to the slide ... so that is not shown below
