I want to know how to convert a word or an excel document into PDF, but
not having any idea how to achieve this.
Kindly give some suggestions. ?

If you need a programmatic way of doing this, use Jacob to read Excel and
Word documents using OLE and use iText to generate the pdf documents. Both
are open source Java libraries.

Otherwise use any pdf printer driver on the market, just select the "Print
to pdf" driver once installed and print your document into a pdf file

ok,

if u r using Microsoft office their is plug-in doing this you can found it on the website of microsoft

Another solution:

import officetools.OfficeFile;
...
FileInputStream fis = new FileInputStream(new File("test.doc")); // works with xls also
FileOutputStream fos = new FileOutputStream(new File("test.pdf"));
OfficeFile f = new OfficeFile(fis,"localhost","8100", true);
f.convert(fos,"pdf");

All possible convertions:
html --> pdf
doc --> pdf, html, txt, rtf
xls --> pdf, html, csv
ppt --> pdf, swf

thank you for this addition

Thanks

Well,another method is borrow a software that is easy to use.Such as Nemo PDF.Nemo PDF Converter 4.0 converts PDF to Word/RTF and Word/Excel to PDF for uses of different situations with speed and 100 accuracy. It keeps intact of the original files and supports batch conversion. You can either batch convert files from the converter or from the button integrated in your documents with ease. Moreover, its user-friendly interfaces will make you a veteran from a new user in minutes.Hope this helps.

I also want some of my files to be converted.
Hoping for the miracle.

There is a website called freepdfconvert.com..converts word and excel both to pdf but online...they mail you the converted file.

If you need a software on your machine then there is free download available at, hellopdf.com/download.php
