In IBM WebSphere Application Server and Oracle WebLogic Server, a file with extension jks serves as a keystore.

JDKs provide a tool named keytoolThe keytool Command - a key and certificate management utility to manipulate the keystore. keytool has no functionality to extract the private key out of the keystore, but this is possible with third-party tools like jksExportKey, CERTivity,CERTivity - A multi-platform visual tool for managing keystores PorteclePortecle - Portecle is an open-source GUI application for creating, managing and examining keystores. and KeyStore Explorer.KeyStore Explorer - An open source GUI replacement for the Java command-line utilities keytool, jarsigner and jadtool.
