How to do implement the FrameAccess.java code in my project

Question

Iam doing an project in java for inserting the videos into oracle9i and searching the inserted videos using the frames of the videos inserted.I have done the project to insert and search the videos.But i have been asked to put an EXTRACT button to extract all the frames of the video being inserted.Please help me to implement the FrameAccess.java coding in my existing coding.I have pasted my coding(VideoInsert.java) and FrameAccess.java(used to extract frames) coding.
The VideoInsert.java when executed will contain browse button to choose the video file(only .mpg files) to be inserted into the database.After selecting the file and when we press open button in the Open dialog box,the video will be played in jmf player in a separate window and the filepath of the video will be included in the textbox.Now what i need is,an extract button should be placed and when it is clicked,the frames of the corresponding selected video has to be extracted in the location where the project files are stored i.e.,the FrameAccess.java coding has to be executed.
Please help me if anyone knows how to implement the above concept.
