Use PDFBOX

public class PDFTextReader
{
   static String pdftoText(String fileName) {
        PDFParser parser;
        String parsedText = null;
        PDFTextStripper pdfStripper = null;
        PDDocument pdDoc = null;
        COSDocument cosDoc = null;
        File file = new File(fileName);
        if (!file.isFile()) {
            System.err.println("File " + fileName + " does not exist.");
            return null;
        }
        try {
            parser = new PDFParser(new FileInputStream(file));
        } catch (IOException e) {
            System.err.println("Unable to open PDF Parser. " + e.getMessage());
            return null;
        }
        try {
            parser.parse();
            cosDoc = parser.getDocument();
            pdfStripper = new PDFTextStripper();
            pdDoc = new PDDocument(cosDoc);
            // pdfStripper.setParagraphStart(FIND_START_VALUE);
            // pdfStripper.setParagraphEnd("FIND_END_VALUE);
            parsedText = pdfStripper.getText(pdDoc);
        } catch (Exception e) {
            System.err
                    .println("An exception occured in parsing the PDF Document."
                            + e.getMessage());
        } finally {
            try {
                if (cosDoc != null)
                    cosDoc.close();
                if (pdDoc != null)
                    pdDoc.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
        return parsedText;
    }
    public static void main(String args[]){

        System.out.println(pdftoText(FILEPATH));
    } 
}

Here i tried this to extract the portion. This may help you.

You can use PDFBox from Apache , honestly speaking i have never used it but read lot about it on the forums.

Other alternative can be iText or JPedal.

If you are interested you can give a try with those , but I am confident that with PDFBox you will be able to meet your requirements.

Thanks

Consider Apache PDFBox

Extract text from PDF and then parse it to get information you want. It is free.

Also there's another tool, iText but if you are working on a commercial project you need to buy a license on iText.
