You can create a custom module, and then add that to the EE subsystem's <global-modules> list to make it available to all applications.

1) Create a directory modules/com/example/mymodule/main/, and put all the jars in it

2) Create a modules/com/example/mymodule/main/ file like this, you need to add all th jars, and may need some more dependencies

<?xml version="1.0" encoding="UTF-8"?>

<module xmlns="urn:jboss:module:1.1" name="com.example.mymodule">

    <resources>

        <resource-root path="this.jar"/>

        <resource-root path="that.jar"/>

        <resource-root path="other.jar"/>

    </resources>

 

    <dependencies>

        <module name="sun.jdk"/>

        <module name="javaee.api"/>

    </dependencies>

</module>

3) Add com.example.mymodule to the global modules list
