To jump right into it: My current understanding is that docx4j does not work with Webpshere Liberty . Please prove me wrong
More below.We're migrating away from Websphere to Liberty. Docx4j worked on Websphere 8.5, with docx4j 3.3.3.
I cannot get things to work on Liberty. Running latest AdoptOpenJDK 8 hotspot version, and tried Liberty kernel versions 8.5.5.9 through 20.0.0.8, and docx4j 3.3.3 all the way up to docx4j-JAXB-Internal and docx4j-JAXB-ReferenceImpl 8.2.1.
We keep having issues. Is there anyone that managed to get Liberty and doc4j working, and if so, how?
Having the following error currently (liberty 20.0.0.8 and docx4j-JAXB-ReferenceImpl 8.2.1)
- Code: Select all

From a working Websphere application, I debugged and noticed with Websphere 8.5/docx4j 3.3.3., it does not go into the tryUsingRI call. So my money is on the fact that Websphere has some classes in its JAXB implementation, that Liberty doesn't, and docx4j can't work without it.
Below is the code for this:
- Code: Select all
public static Object getPrefixMapper() throws JAXBException {
if (prefixMapper!=null) return prefixMapper;
if (haveTried) return null;
// will be true soon..
haveTried = true;
if (testContext==null) {
java.lang.ClassLoader classLoader = NamespacePrefixMapperUtils.class.getClassLoader();
testContext = JAXBContext.newInstance("org.docx4j.relationships",classLoader );
}
if (testContext==null) {
throw new JAXBException("Couldn't create context for org.docx4j.relationships. Everything is broken!");
}
if (testContext.getClass().getName().equals("org.eclipse.persistence.jaxb.JAXBContext")) {
log.info("Using MOXy NamespacePrefixMapper");
try {
Class c = Class.forName("org.docx4j.jaxb.moxy.NamespacePrefixMapper");
prefixMapper = c.newInstance();
return prefixMapper;
} catch (Exception e) {
throw new JAXBException("Can't create org.docx4j.jaxb.moxy.NamespacePrefixMapper", e);
}
}
if (testContext.getClass().getName().equals("com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl")) {
log.info("Using com.sun.xml.internal NamespacePrefixMapper");
try {
Class c = Class.forName("org.docx4j.jaxb.suninternal.NamespacePrefixMapper");
prefixMapper = c.newInstance();
return prefixMapper;
} catch (Exception e) {
throw new JAXBException("Can't create internal NamespacePrefixMapper", e);
}
}
Marshaller m=testContext.createMarshaller();
return tryUsingRI(m);
}
I would expect him to go into the following (which happened in the old docx4j 3.3.3 with Websphere 8.5), which doesn't happen for Liberty:
- Code: Select all
if (testContext.getClass().getName().equals("com.sun.xml.internal.bind.v2.runtime.JAXBContextImpl")) {
log.info("Using com.sun.xml.internal NamespacePrefixMapper");
try {
Class c = Class.forName("org.docx4j.jaxb.suninternal.NamespacePrefixMapper");
prefixMapper = c.newInstance();
return prefixMapper;
} catch (Exception e) {
throw new JAXBException("Can't create internal NamespacePrefixMapper", e);
}
}
Any help please?
Cheers
Jannik
Do you have a support agreement with Plutext? If not we can probably still help, but on a fee-for-service basis.
