Let's learn how to generate PDF file in java using iText library. we will learn to add text, In this iText tutorial, I am writing various code examples read a pdf file and .. This will be needed when you want to stream the PDF file in a client- server. For downloading a file from the server, here is the simple example. But if there is any java file or jsp file etc, you need to create a program to download that file. package wildlifeprotection.info; import wildlifeprotection.info; //Windows solution to view a PDF file public class WindowsPlatformAppPDF { public static void.

It is important to set the MIME type of the file you want to open in the servlet's response object. For this example, I will open a PDF document.

Plug-ins can be associated with a MIME type or types, so that when the Web browser downloads a file with that MIME type, the browser also launches the plug-in that handles the file.

Other MIME types can be associated with external programs. When the browser downloads files of those MIME types, it launches the appropriate program to view the downloaded file.

MIME types are useful because they allow Web browsers to handle various file types without having the built-in knowledge. Using the proper MIME type helps to ensure that the file gets displayed by the proper plug-in or external viewer.

In that MIME type, vnd refers to application vendor that must be included to open the file. In some cases, the browser doesn't recognize the file's MIME type.

Your Answer

That often happens when the required plug-in hasn't been installed for a certain file type. In those cases, the browser will pop up a dialog box, asking the user whether he or she wants to open the file or save it to disk. Content disposition An HTTP response header named content-disposition allows the servlet to specify information about the file's presentation.

Using that header, you can indicate that the content should be opened separately not actually in the browser and that it should not be displayed automatically but rather upon some further action by the user. You can also suggest the filename to be used if the content is to be saved to a file.

That filename would be the name of the file that appears in the Save As dialog box.

If you don't specify the filename, you are likely to get the name of your servlet in that box. You can find me on Facebook , Twitter and Google Plus. Here you have showed some examples by manually entering values that we want to print. There is no where mentioned about it here. So, can you tell how to do or where can I look more for it.

I have worked in Jasper Reports and they feel much more easier than the approach that is being used here. Hi Bharat, Thanks for putting your question here. I also had some little experience of working on jasper reports and we were using that for generating reports using iReport.
