XHTML image conversion causes HeadlessException

[mhast]

I am getting the HeadlessException when converting an image from XHTML to docx.

I found this (docx-java-f6/problem-to-create-word-s-file-with-images-on-linux-server-t322.html#p967) which says to use a more updated version of xmlgraphics-commons.jar. That was in 2010. I downloaded docx4j a couple of days ago and have xmlgraphics-commons-1.4.jar from 30-Sep-2012.

I also found this (http://stackoverflow.com/questions/1156 ... hat-server) which says there is an update in flyingsaucer that fixes this issue. I downloaded their version of the xhtmlrender jar file which is not compatible with xhtmlrenderer-1.0.0.jar which uses a different package structure. How can I update ImageUtil.java in xhtmlrenderer-1.0.0.jar and build it to try it?

I am using -Djava.awt.headless=true when running my application.

Anyone?

The source code for xhtmlrenderer-1.0.0.jar is at https://github.com/plutext/flyingsaucer

Hi jason:

I got the source and cloned the git repo. I also found the file and found the location of the fix. Ahhhmmm, can you give me some pointer on how to build it?

With
ant -Dapp.version=1.0.1 dist

I get
...
BUILD FAILED
/Users/mhast/Developer/eclipse_workspaces_3_7/dss/flyingsaucer/build.xml:70: The following error occurred while executing this line:

I got it. I had to use Maven to build the project. The patch above is working just fine when needing to run in headless mode. However when I run the XHTML conversion via command line I get much better results than running the same conversion in my J2EE app, weird. I am using the example code from ConvertInXHTMLDocument.java. Maybe on command line the more font's can be read in or something. So I will be sticking with command line.

The difference may be whether the two config files in docx4j's src/main/resources are available or not.
