Deployed Web application getting nosuchmethod error for javax.json.JsonValue.asJsonArray - Jboss eap 7.0 linux server

Question

I have a web application deployed to jboss eap 7.0 on linux.

Within my java code I am using javax.json.JsonValue.asJsonArray method. When I run locally on tomcat all runs fine.

Once I deploy to Jboss I get a nosuchmethod error on asJsonArray method. within my WEB-INF\lib folder I have the necessary json jar with that method javax.json-1.1.4.jar. I have discovered that under modules within Jboss it has its own version of javax.json \jboss-eap-7.0\modules\system\layers\base\org\glassfish\javax\json\main\javax.json-1.0.3.redhat-1.jar.

It is my speculation that when I run my application it is first looking at jar within the Jboss modules directory rather than the jar within the WEB-INF\lib folder in the war file. How do I direct the application to reference the jar within the WEB-INF\lib and not the jar withing the jboss modules?

You can exclude the JBoss provided dependency using jboss-deployment-structure.xml file which you need to place under the WEB-INF directory of your war. You have to specify the exclusion dependencies something like below.

`<jboss-deployment-structure>  
 <deployment>  
    <exclusions>  
        <module name="$LIBRARY_OR_MODULE_YOU_WANT_TO_EXCLUDE"/>  
    </exclusions>  
 </deployment>
 </jboss-deployment-structure>`

e.g. <module name="javax.json.api"/>
