We're using docx4j to produce Word 2007 output from our application, but are having a problem with null class loaders.

in org.docx4j.jaxb.Context there is the following code:

Code: Select all

try {   
         
         // JBOSS might use a different class loader to load JAXBContext, which causes problems,
         // so explicitly specify our class loader.
         Context tmp = new Context();
         java.lang.ClassLoader classLoader = tmp.getClass().getClassLoader();
         //log.info("\n\nClassloader: " + classLoader.toString() );         
         
         log.info("loading Context jc");      

However, when our application is running standalone (running from command line) the classLoader variable is null.

The command line looks like:

Code: Select all

..\jre6\bin\java -Dlog4j.configuration=.\conf\log4j.xml -Djava.endorsed.dirs=".\endorsed" -Xms1024m -Xmx1024m -server -jar .<myJarFile>

Is there some configuration we should be adding to ensure we get a value for classLoader?

Running the application as an applet through our IDE picks up a Tomcat class loader successfully and docx4j then works fine, but we need it to work standalone too.

You could try removing the explicit classloader (as per below .. if it works, you'll need to do it in a few other places as well, eg jcXslFo)

Code: Select all

Thanks for your help.

Have added a check to see if the classLoader variable is null, if it isn't we use it otherwise we don't try and now it is working fine.
