JAXBException namespacePrefixMapper is null

[borja]

Hi,

This is first time i'm using docx4j with MAVEN. Im following the instructions on getting started guide. (java version 1.8 and OpenJDK 13)

So, Im using OpenJDK 13 i think i cannot use JAXB internal (is this right?), anyway i tried and i get a class not found exception of com.sun.xml.internal.bind.v2.ContextFactory

Because of this, Im trying now reference implementation. I tried versions 8.1.0, 8.1.1 and 11.1.0 and i get this error:

javax.xml.bind.JAXBException: namespacePrefixMapper is null

So im unable to get docx4j working with maven.

Any help?

Thanks

I changed my JDK version to 8 and using jaxb-internal i get same error javax.xml.bind.JAXBException: namespacePrefixMapper is null

I read in other thread that you plan to release 8.1.2 version to fix this issue next week. But im not using any kind of multithreading here.

What are your Maven dependencies?

Hi Jason,

Now, i only have:

Code: Select all

<dependency>
                    <groupId>org.docx4j</groupId>
                    <artifactId>docx4j-JAXB-Internal</artifactId>
                    <version>8.1.1</version>
                </dependency>
                <dependency>
                    <groupId>org.slf4j</groupId>
                    <artifactId>slf4j-api</artifactId>
                    <version>1.7.5</version>
                </dependency>


The others are related to spring boot. Anyway im going to wait until next release and see if it works.

Is there compatibility issues with OpenJDK? Because other times i used docx4j i always used oracle.

Thank you!

Those deps look good.

8.1.2 is out now, so please try it and let us know whether it helps.

OpenJDK is generally fine.

Hi,

I checked the new release. I get a different error, but seems to be a problem related to my environment. Because i have synced the project to other computer and it works perfectly well.

I get this error:
org.docx4j.openpackaging.exceptions.Docx4JException: Error marshalling Content_Types

Using Pop!_OS 19.04
openjdk version "1.8.0_212"
OpenJDK Runtime Environment (build 1.8.0_212-8u212-b03-0ubuntu1.19.04.2-b03)
OpenJDK 64-Bit Server VM (build 25.212-b03, mixed mode)

In the other computer that it works im using Debian 9 but don't remember what version of JDK, but im sure its oracle and not OpenJDK. This could be the problem?

Thank you

What's the complete stack trace? What code triggers it? Does it happen with a simple Hello World.docx?

[borja]

Sorry for delay. I will try to provide you this info and do some tests.
