How to extract content of PDF file using java?

I want to extract the content of one pdf file and want to store it in Text File using java..How to convert this..?Is there any Inbuilt class is available for doing this? Posted in: #Java

First you have to read carefully PDF file specifications, you may find it here Adobe - PDF Developer Center: PDF reference, then read file metadata & scrap the actual text according to the file's spec.

The problem is in understanding the pdf file structure after recognizing the metadata the rest is as reading normal text files.
