ClassNotFoundException in Module - How to reference javax.json module?
I have written a HttpHandler which is defined as a module. Everything works fine but when I try to use JSON I get a ClassNotFoundException (stacktrace below)
I'm new to WildFly so I don't fully understand the module system yet so please bear with me.
Along with module.xml I have log4j-api-2.7.jar, log4j-core-2.7.jar, log4j-web-2.7.jar and my handler classes in gatekeeper-1.0-SNAPSHOT-wildfly.jar
My module.xml is as follows:
<module xmlns="urn:jboss:module:1.3" name="no.company.gatekeeper">
<resources>
<resource-root path="gatekeeper-1.0-SNAPSHOT-wildfly.jar"/>
<!-- hack to make things work with log4j since the module org.apache.logging.log4j.core below is not working -->
<resource-root path="log4j-api-2.7.jar"/>
<resource-root path="log4j-core-2.7.jar"/>
</resources>
<dependencies>
<module name="javax.api"/>
<module name="io.undertow.core"/>
<module name="org.slf4j"/>
<!-- not really working -->
<!--<module name="org.apache.logging.log4j.core"/>-->
</dependencies>
</module>
Is there a javax.json module in WildFly and how do I reference it ?
