[jboss-jira] [JBoss JIRA] (WFLY-4286) ClassNotFoundException from xmlschema-core.jar

[David Lloyd (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-4286?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

David Lloyd resolved WFLY-4286.
-------------------------------
    Resolution: Rejected


No, this is a usage error.  WildFly does bundle this library, however it is not added to a deployment's class path by default.

You can include this dependency by adding a header like this to your MANIFEST.MF file (use the maven JAR plugin):

{noformat}
Dependencies: org.apache.ws.xmlschema
{noformat}

This will allow you to re-add the "provided" scope to your POM dependency specification.

> However when i Deploy my Application to a Default Wildfly 8.2 Installation (Runs on JDK 1.8.31) then I get the following error:

>    <groupId>org.apache.ws.xmlschema</groupId>
>    <artifactId>xmlschema-core</artifactId>
>    <version>2.0.2</version>
>    <!--<scope>provided</scope>-->
> </dependency>
> The ClassNotFoundException doesn't occur anymore. May this be a bug?
