jboss-client.jar is required by the server at runtime. There are several ways of providing jars to a JBoss server -

1. include jars in MANIFEST.MF (this is generally used for your own application jars)
2. include jars in WEB-INF/lib - if the jar is specific to the given web project or WAR
3. include jars in a module class loader and provide it to the web project via jboss-deploymet-structure.xml . This is done when there are multiple WARS and some of them (not all) need the jars.
4. include jars in a module class loader and provide it to the server via global modules in standalone.xml . This is done when the jars are being referenced by all applications deployed on the server.

For details on modules in JBoss, please refer to this link - https://docs.jboss.org/author/display/AS7/Class+Loading+in+AS7

As to your question on how putting the jboss-client.jar in a WAR instead of testclient.jar is resolving the issue, the answer is the same - this is how class loading works.
