Answer 1

Wenn com.xyz ein Paket von Drittanbietern ist, müssen Sie die Sichtbarkeit der API-Pakete von Drittanbietern in der Datei "Liberty server.xml" festlegen, damit die Anwendung auf sie zugreifen kann.

Hoffentlich sollte diese Dokumentation helfen: https://www.ibm.com/support/knowledgecenter/en/SSEQTP_8.5.5/com.ibm.websphere.wlp.doc/ae/twlp_classloader_3p_apis.html
