wildfly 10: java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory

I have a maven application that works fine in wildfly 8.2, but when Ideployed it in wildfly 10 this error happened:

[2016-02-21 11:22:08,411] Artifact SaramadIssueTracking:war exploded: Error during artifact deployment. See server log for details.
[2016-02-21 11:22:08,411] Artifact SaramadIssueTracking:war exploded: java.lang.Exception: {"WFLYCTL0080: Failed services" =>

    Caused by: java.lang.ClassCastException: org.dom4j.DocumentFactory cannot be cast to org.dom4j.DocumentFactory"}}

I read this and there was no other dom4j library. I also read this and did it, but after removing dom4j, I got this error:

Solution 1:

I just made all hibernate dependencies provided scope and problem solved!

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-core</artifactId>
            <version>5.1.0.Final</version>
            <scope>provided</scope>
        </dependency>

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-validator</artifactId>
            <version>5.2.4.Final</version>
            <scope>provided</scope>
        </dependency>

        <!-- for JPA, use hibernate-entitymanager instead of hibernate-core -->
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-entitymanager</artifactId>
            <version>5.1.0.Final</version>
            <scope>provided</scope>
        </dependency>

        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-ehcache</artifactId>
            <version>5.1.0.Final</version>
            <scope>provided</scope>
        </dependency>

Solution 2:

add dependency dom4j to pom with scope provided

<dependency>
   <groupId>dom4j</groupId>
   <artifactId>dom4j</artifactId>
   <version>1.6.1</version>
   <scope>provided</scope>
</dependency>

Solution 3:

I had recently the same problem with the dom4j library and Wildfly 10. I found this post (in portuguese) and replaced the dom4j library that comes with Wildfly with the one downloaded from the Maven Central, and that solved the problem.

The jar is located in $JBOSS_HOME/modules/system/layers/base/org/dom4j/main, you just replace it with the downloaded file, in my case the file was dom4j-1.6.1.jar. I suppose that if you change the version (at the time of this post this is the last version) you should also modify the module.xml file in the same folder, but I've not tried.

Previously I also tried the self-answer from h.f but didn't solved my problem.

Hope this contributes to someone with the same problem. Best regards

Solution 4:

If you are using hibernate-core as a dependency, you should make sure the scope is provided. The hibernate artifact has a version of dom4j as a dependency, by making changing the <scope> to provided resolves the conflict.

    <dependency>
        <groupId>org.hibernate</groupId>
        <artifactId>hibernate-core</artifactId>
        <version>4.3.1.Final</version>
        <type>jar</type>
        <scope>provided</scope>
    </dependency>

I hope this makes you smile :)
