Xalan dependencies

[Franke]

When reading a normal docx with just a few paragraphs, tables, header + footer and two images, I get an error:

Code: Select all

ERROR: XmlUtils: javax.xml.transform.TransformerFactoryConfigurationError: Provider org.apache.xalan.processor.TransformerFactoryImpl not found (XmlUtils.java, line 131)

However, the file parses fine, but what is this dependency about? If I do add xalan-2.7.1.jar I can read the file without errors occuring, but the save method throws a no class found exception:

Code: Select all

So it seems that docx4j has additional dependencies compared to the getting started, AND the lib itself that comes with is corrupt? Thoughts on this? It really works fine just ignoring the library, but I dislike getting random errors.

See the static initializer in XmlUtils. If anything in that class is used, the static init is of course executed, and it is that that configures the transformer.

I'll update the Getting Started guide so that where it refers to Xalan, it refers to Xalan and its dependencies. You can get the dependencies from the docx4j download dir, from the Xalan distribution, or via maven.

Ah thank you, it works better now. On a related matter, when exporting to PDF, it seems to require batik-util.jar from Apache, this might also be good to put on the getting started page.
