[jboss-jira] [JBoss JIRA] (WFLY-12827) Class not found com.sun.xml.internal.ws.encoding.StringDataContentHandler

    [ https://issues.jboss.org/browse/WFLY-12827?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13818328#comment-13818328 ] 

Dominik Derwiński commented on WFLY-12827:
------------------------------------------

For now I have confirmed your findings that mailcap[-default] files are only in jakarta.activation-1.2.1.jar and jakarta.mail-1.6.4.jar, and they do not reference those wrong classes directly.

I have also found out that WildFly uses com.sun.activation:jakarta.activation:1.21 which contains com.sun.activation.registries and com.sun.activation.viewers packages, whereas pulling JAXB and JAX-WS reference implementations (org.glassfish.jaxb:jaxb-runtime:2.3.2 and com.sun.xml.ws:jaxws-rt:2.3.2) into my projects (I don't want to deal with specifics of using two different implementations of those standards in EE apps, and standalone apps + test classes; and on JDK 11 have no choice but to add them as dependencies), pulls jakarta.activation:jakarta.activation-api:jar:1.2.1, which contains same classes as com.sun.activation:jakarta.activation:1.21 in javax.activation package, but no com.sun.* packages and no mailcap.default file.

Similar issues may arise from pulling jakarta.mail:jakarta.mail-api:jar:1.6.4 (no mailcap file) instead of com.sun.mail:jakarta.mail:1.6.4 (has mailcap file and depends on com.sun.activation:jakarta.activation).

Seems like it may be a problem of my own making, created by the confusion of removing classes in JDK and Jakarta EE renames. I'll check if the problem will be gone with fixing the dependencies.

> Maybe it's just missing module dependency for javax.mail.api, maybe you need to include JAXB and JAXWS libraries in WildFly modules for use on JDK 11+, when they were removed from JDK.
