Oracle allows you to use the CREATE JAVA statement to create specific schema objects containing Java sources, Java classes, or Java resources. Java Resource Editor provides you with an ability to create a schema object containing a Java resource easily and quickly.
Java Resource Editor allows you to define Java resource properties. It opens automatically when you create a new Java resource and is available on editing an existing one.
To open a Java resource in Java Resource Editor, double-click it in the DB Explorer tree.
