Problem inserting "internal" hyperlink

[guams]

Hi,

I have to add internal hyperlink (a reference to a bookmark) to a document but I don't know how to do.

I try to change the HyperlinkTest Sample, removing the instruction

Code: Select all

rel.setTargetMode("External");

But I had an exception: org.docx4j.openpackaging.exceptions.Docx4JException: Failed to add parts from relationships


I also tried to load a document which contains "internal hyperlink" with the OpenAndTraverseDocument Sample and I had the following exception:

Code: Select all

Is it a bug or a feature not supported?

[jason]

also tried to load a document which contains "internal hyperlink" with the OpenAndTraverseDocument Sample and I had the following exception

You should never get an error loading a valid docx...

What version of docx4j are you using - 2.6.0 or the latest nightly, or something else?

Can you upload the docx and I will take a look?

[guams]

Ok, I cannot share the docx I'm working on, but I reproduce the bug with another small document.

I'm using docx4j 2.6.0.

[jason]

I'm a bit surprised that has never come up before, but in any case it is now fixed as http://dev.plutext.org/trac/docx4j/changeset/1481

I will make a nightly build tonight.

To answer your original question properly, are you trying to add your internal hyperlink from an image as per this example docx, or from text?

[guams]

From an image.

[guams]

Hi Jason

With the nightly build, I still have an exception:

java.io.IOException: part 'word/document.xml#toto' not found
etc...

[jason]

I haven't made a nightly build yet

ok ... see now http://dev.plutext.org/docx4j/docx4j-ni ... 110419.jar

[guams]

Ok, it works now.... but I still don't know how to add hyperlink from an image.

[jason]

Here is a sketch of how to do it.

You are looking to add hlinkClick to wp:docPr:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using xml Syntax Highlighting

            <wp:docPr id="2" name="Image 1" descr="Coucher de soleil.jpg">
              <a:hlinkClick xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main" r:id="rId4"/>
            </wp:docPr>
 

Parsed in 0.001 seconds, using GeSHi 1.0.8.4

in

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using xml Syntax Highlighting

        <w:drawing>
          <wp:inline distT="0" distB="0" distL="0" distR="0">
 

Parsed in 0.000 seconds, using GeSHi 1.0.8.4

Where your r:id is an internal hyperlink.

First the code from HyperlinkTest sample:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

                        org.docx4j.relationships.ObjectFactory factory =
                                new org.docx4j.relationships.ObjectFactory();
                       
                        org.docx4j.relationships.Relationship rel = factory.createRelationship();
                        rel.setType( Namespaces.HYPERLINK  );
                        rel.setTarget(url);
                        rel.setTargetMode("Internal");  
                                                                       
                        wordMLPackage.getMainDocumentPart().getRelationshipsPart().addRelationship(rel);
 

Parsed in 0.015 seconds, using GeSHi 1.0.8.4

Assuming org.docx4j.dml.wordprocessingDrawing.Inline inline,

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using java Syntax Highlighting

CTNonVisualDrawingProps docPr = inline.getDocPr();

org.docx4j.dml.ObjectFactory dmlOF = org.docx4j.dml.ObjectFactory.ObjectFactory();
org.docx4j.dml.CTHyperlink hyperlink = dmlOF.createCTHyperlink();

docPr.setHlinkClick(hyperlink);

hyperlink.setId(rel.getId() );

 

Parsed in 0.013 seconds, using GeSHi 1.0.8.4

Please confirm this works and/or post for the benefit of others a version with whatever tweaks you find necessary

[jason]

Just committed http://dev.plutext.org/trac/docx4j/changeset/1482 which should fix this.

I'll make a nightly later .. will edit this post to say so when done.

[guams]

Hi Jason,

When do you think a nightly build for this feature will be available?

regards

[jason]

Sorry, Easter got in the way.

Here it is: http://dev.plutext.org/docx4j/docx4j-ni ... 110426.jar

cheers .. Jason

[guams]

Ok, it works fine now.

Thanks for the help and quick support

Hi Jason, I have a problem related to this. I can create external hyperlinks no problem. I tried creating hyperlinks by setting the target mode to "Internal". The code compiles and runs just fine, but when I try to open the document it says it's corrupt. If I tell word to open in anyway, it opens just fine and even the links work ok, they go to the bookmark and everything. Any ideas?

Thanks, Nicolas

[jason]

You haven't given me much to go on

What does your code look like? Are you sure it is the hyperlink stuff which is the problem, and not something else you are also doing to the docx file?

[UndefienedUser]

Hi Jason,

Is it the same process to add an internal hyperlink from text?

thanks

[UndefienedUser]

Hi, No idea ...?

[jason]

This whole thread is confusing/confused, because usually you don't need a rel at all for an internal hyperlink.

Please see http://www.docx4java.org/blog/2012/04/d ... yperlinks/

[UndefienedUser]

Thanks a lot i got it!!
