7.20.0-alpha5 DomXmlDataFormat depends on javax.xml.bind instead of jakarta

I am migrating org.camunda.bpm.springboot:camunda-bpm-spring-boot-starter-external-task-client to 7.20.0-alpha5 in a Spring Boot 3.1.4 Java 17 application. The application cannot start up because the creation of the application context fails with

Caused by:
                java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException
                    at org.camunda.bpm.client.variable.impl.format.xml.DomXmlDataFormatProvider.createInstance(DomXmlDataFormatProvider.java:31)

shouldn’t DomXmlDataFormat have a dependency on jakarta and not javax?

I can build and run the project if I include “javax.xml.bind:jaxb-api:2.4.0-b180830.0359” but Spring Boot migrated to jakarta as did other camunda packages.

Have you tried including camunda-spin-dataformat-xml-dom-jakarta instead of “camunda-spin-dataformat-xml-dom”?

i do not understand how that could solve my problem? i don’t even have a dependency on that. we are using only a dependency on

camunda-bpm-spring-boot-starter-external-task-client

which depends on the camunda-external-task-client which contains the DomXmlDataFormat which imports the javax.xml.bind:

org.camunda.bpm.springboot:camunda-bpm-spring-boot-starter-external-task-client:7.20.0-alpha6
+-- org.camunda.bpm:camunda-external-task-client-spring:7.20.0-alpha6
+-- org.camunda.bpm:camunda-external-task-client:7.20.0-alpha6 <- HERE DomXmlDataFormat

i already tried the alpha6 with the same result.

Is there any answers to this. We are having the same issues with the latest release 7.20.0

Lucas_Scarlatta · December 6, 2023, 5:03pm

Any update on this. I have the same issue after upgrade to camunda 7.20.0. Or is there a workaround to use it?

I’d try to manually exclude one artifact and include the other.

### Environment (Required on creation) External Task Client Spring/Spring Boot 7….20 ### Description (Required on creation; please attach any relevant screenshots, stacktraces, log files, etc. to the ticket) External Task Client Spring/Spring Boot require `javax` library despite Spring Boot 3 migrated to `jakarta` domain. ### Steps to reproduce (Required on creation) 1. Setup a minimal client example, e.g.:https://github.com/camunda/camunda-bpm-platform/issues/3441#issuecomment-1753574729 2. Start the client ### Observed Behavior (Required on creation) Exception thrown `Caused by: java.lang.NoClassDefFoundError: javax/xml/bind/JAXBException` ### Expected behavior (Required on creation) No error ### Root Cause (Required on prioritization) Dependency is coming from External Task Client Java: https://github.com/camunda/camunda-bpm-platform/blob/master/clients/java/client/src/main/java/org/camunda/bpm/client/variable/impl/format/xml/DomXmlDataFormat.java The java client still uses `javax` library. ### Solution Ideas ### Hints * The spring boot example must be adjusted accordingly too: https://github.com/camunda/camunda-bpm-examples/blob/7.20/spring-boot-starter/external-task-client/loan-granting-spring-boot-webapp/pom.xml#L92-L96 ### Links - https://github.com/camunda/camunda-bpm-platform/issues/2755 - https://jira.camunda.com/browse/SUPPORT-18875 ### Breakdown  ```[tasklist] ### Pull Requests - [ ] https://github.com/camunda/camunda-bpm-platform/pull/3862 ``` ### Dev2QA handover - [ ] Does this ticket need a QA test and the testing goals are not clear from the description? Add a [Dev2QA handover comment](https://confluence.camunda.com/display/AP/Handover+Dev+-%3E+Testing)

A workaround will be add the jaxb-api dependency for the time being. Similar to this example:
