Abstract
The present invention is to provide a method for enabling Blue-ray Disc Java (BD-J) to effectively obtain context of a corresponding application, namely an Xlet, while playing BD-J title, which comprises the steps of setting up source file attribute of each class by adding an Xlet context ID as an unique code to the class when loading all classes into a cache of the BD-J; looking up back onto a call stack to search for Xlet class of the current BD-J title when searching for Xlet context; and then obtaining the Xlet context through the Xlet context ID according to the source file attribute. Thus, the method of the present invention enables BD-J to normally play the BD-J title in the Blue-ray Disc Read Only Memory (BD-ROM) and, at the same time, effectively improves the playing performance.
