How do I turn off logging for AbstractMessageWriter

[VMSZealot]

My apologies - it's another (I'm sure) stupid question (I'm still a Java noob). As before https://www.docx4java.org/forums/docx-java-f6/converting-docx-to-html-using-intellij-and-maven-t2978.html?sid=50d296c922fc798a947a6e3ec26538b0, this is IntelliJ and Maven.

The conversion works well (thank you) with the following code - except that there's an error message embedded in the output "TO HIDE THESE MESSAGES, TURN OFF debug level logging for org.docx4j.convert.out.common.writer.AbstractMessageWriter":

Configuration - which is in /src/main/configuration, and which I ripped from Github (without properly understanding it I'm afraid). I've set the configuration folder to be marked as 'sources' as suggested in a stack overflow answer, because I think that adds it to the class path and makes it available.

I've looked at the answers on this site (including their counterparts in places like Stack Overflow), and tried everything - and only succeeded in making a mess. I've tried subclassing log4j, I've tried configuration files - this is the closest that I've found to a solution that might be right - but it still doesn't work.

Ideally, I'd like a solution which allows me to turn on or off the level of logging using a parameter - but, failing that, I'd like to know what configuration I need to turn off logging.

Thank you in advance for any help that you can provide.

You are using logback:

Syntax: [ Download ] [ Hide ]

Syntax: [ Download ] [ Show ]

Using xml Syntax Highlighting

        <dependency>
            <groupId>ch.qos.logback</groupId>
            <artifactId>logback-classic</artifactId>
            <version>1.2.3</version>
        </dependency>
 

Parsed in 0.001 seconds, using GeSHi 1.0.8.4

So you need the logback configuration XML: https://github.com/plutext/docx4j/blob/ ... ck.xml#L48 (this link points at the line you need to alter)

(Your post contains the log4j XML, which is only useful if you use log4j as the logging implementation)

Putting logback.xml in src/main/configuration ought to work....

Thank you very much! That's great - and it fixed my noob problem. I think that's it all working now, thanks to your software and your help.
