//Preparing parameters

Map parameters = new HashMap();

One suggestion, have you tried writing the byte array to file instead of the browser to see whether the PDF looks OK?

Sghafai sakina,

We have hundreds of posts every day and by marking you title as URGENT does not help you out. If you want to get any help, you should make your title more descriptive. Many people when they see the word URGENT in a post, they tend to ignore it.

You should be sending a PDF file from a servlet, not a JSP. JSP are designed to write characters streams.

As William said, JSP is a poor technology choice for non-text responses. And as Eric said, URGENT is a poor choice for a topic title. I have edited the title accordingly.
