Weblogic server and Jersey servlet issue
<p>I start the Oracle Weblogic Server 12c R2 (12.2.1) on Eclipse, it can be synchronized, but has some issues below.  I have added the Jersey library 1.17, not sure if it is too old version. But I could find the correct download link for the latest. </p>

<p>Could someone help to figure out how to fix this?</p>
