Docx to Pdf Conversion- needs JAXB RI NamespacePrefixMapper?

[heitorflorido]

Hello,
I'm using docx4j 2.5.0 to write some docx files and it's working great!
Now I want to convert these files to Pdf and I'm getting this error:

Code: Select all

I'm using Eclipse helios, JDK 1.6.0_20.

I've read on another thread that I should download a JAXB RI and put it my endorsed libs dir, but I don't know how to do it.
Anyone can help me?

Hi, you should only need both implementations of JAXB if you are building from source.

If you are not building from source, then this is a bug, which I just fixed. See http://dev.plutext.org/trac/docx4j/changeset/1184 (hmm, you'll need to build from source to get this, or wait for a nightly. In the meantime, you can use the endorsed dir mechanism: in Eclipse, its Run > Run Configurations, then add the VM argument -Djava.endorsed.dirs=etc).

If you are building from source, then you need both JAXB implementations. You need both, so that com/sun/xml/bind/marshaller/NamespacePrefixMapper is found at build time. Your RI does not need to be in an endorsed dir for this to be the case I don't think - it just needs to be on your class path. And the Maven POM should take care of this if you use m2eclipse.

While I'm waiting for a nightly build, which folder should I my -Djava.endorsed.dirs should point to?
The JAXB RI jar should be there too?

Thanks

Point -Djava.endorsed.dirs to wherever you put the JAXB RI.

Anyway, you can now try http://dev.plutext.org/docx4j/docx4j-ni ... 100814.jar

jason, now the PDF conversion is working. Thanks man.

However, I have some questions about the output file. I'm going to open another thead for this.

Should I edit this post title and add [SOLVED] to it?

Thanks again
