ContentType is used to display MIME (Multipurpose Internet Mail.

NEVER store data in your webapp directory. Secondly, because even allowing for the fact that Tomcat explodes WARs by default, thus giving "real" directories, storing data in a WAR can cause it go get lost when the app is updated or in some other cases as well. For temporary files, you should use the java. For non-temporary files, use an absolute external file directory path. If you don't want to hard-code such a path into the webapp, you can supply it via the J2EE environmental interface and retrieve it using JNDI. You should not have any OS-dependent code in your webapp. Portability issues in webapps are more usually because of what server you're using, not which OS you're running. There are features in java. File that can prevent you from having to worry about things like slashes versus backslashes and can join and break apart path components. To create and download a PDF from a webapp, you need two functionalities. First, create the PDF in a temporary directory. Maybe you could create it in RAM, depending on what library you're using, but it's going to eat a lot of working storage in most cases if you do. Then simply copy the PDF file from the temporary directory to the servlet response outputstream. Please note that Tomcat is not a file server.

Sorry There was an error emailing this page. To open a file in a browser from a servlet, you simply write the file to the servlet's output stream. While that seems simple enough, you must be aware of some things when opening non-HTML documents such as binary data or multimedia files.

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.

How To Set PDF File Display In Servlet

I don't know if this still applies, but some browsers could not handle PDF's unless the content length header was correctly set. Since an on-the-fly PDF generation doesn't know how large it will be until long after the headers have been sent, that forced the need to create a temporary PDF file on the server and then spool it out in the response stream with a content-length header.

Sorry about that. You can minimize the annoyance, however. Use the java. There's also an option that allows the file to be automatically deleted after it is read, which leaves only the grunt work of copying from the SPOOL file to the HttpOutputStream. Ben Souther.

I know that iText can be used to create PDFs in memory to be streamed to the browser. This might be desirable for smaller PDFs but, for larger ones, you might prefer to stream them to a file and then stream that file to the browser. I've been able to stream PDFs to current browsers without knowing the content length.

In the app I'm working on, I don't need to support older browsers so I'm not sure which ones required the content length header. I do know that this issue is covered in "iText In Action" by Bruno Lowagie along with some workarounds. Last note: And yes i am also worried of the commercial license clause for close code application attached with iText, please suggest any generic way of doing this.

The web application is deployed on Tomcat server.
