"MessageBodyWriter not found for media type=application/xml" error preventing upgrade from 2.32 to 2.33

[jluehe]

We are currently running with Jersey 2.32 and trying to upgrade to latest version. However, trying to upgrade to 2.33 already gives an error:

org.glassfish.jersey.message.internal.WriterInterceptorExecutor[] [...] MessageBodyWriter not found for media type=application/xml, type=class test.framework.common.pojos.TestResults, genericType=class test.framework.common.pojos.TestResults.

I have looked at the delta between versions 2.32 and 2.33 (2.32...2.33), but don't see anything obvious that could be causing this error.

There are no other changes.

Any ideas?

Do you have

             <groupId>org.glassfish.jersey.media</groupId>
             <artifactId>jersey-media-jaxb</artifactId>

dependency in your classpath? If you use JDK 11+ there should be also

            <groupId>jakarta.xml.bind</groupId>
            <artifactId>jakarta.xml.bind-api</artifactId>

,

           <groupId>com.sun.xml.bind</groupId>
           <artifactId>jaxb-osgi</artifactId>

dependencies.

Thank you, @senivam, for your reply!

Yes, I do have the following (we are using JDK 17):

• javax.xml.bind:jaxb-api:2.3.0
• org.glassfish.jersey.media:jersey-media-jaxb:2.32

I do not have com.sun.xml.bind:jaxb-osgi though. Is it required? As I said, everything works fine with 2.32, it is only when I upgrade to 2.33 that I get the error ...

[senivam]

I hope, in reality, you have
org.glassfish.jersey.media:jersey-media-jaxb:2.33
not 2.32 as is the previous version you are migrating from.

could you please supply the output of the mvn dependency:tree for the module you are having error with?

[jluehe]

I am upgrading all Jersey artifacts at the same time, so yes, as part of the upgrade, I am bumping org.glassfish.jersey.media:jersey-media-jaxb to 2.33 as well.

Will supply the dependency tree shortly ...

@jluehe I assume this is solved and can be closed?

[jluehe]

Thanks for getting back to me, @jansupol! So far I have not been able to resolve the issue, but have not had time to look into it further ...

[jluehe]

@jansupol, actually, this is fixed now. Turns out org.glassfish.jersey.media:jersey-media-jaxb was missing from the class path. Thanks for your help!
