How to write data into PDF using Servlet
The file name must conform to the target machine's local file system conventions. After all this is only a suggestion, it does not guarantee that the file name you give will be used.
If the target system decides that the filename represents some security problems for whatever reasons it may decide to rename the file. You will have better luck by using "attachment" instead of "inline" it may not fit your requirements, though.
This is what the RFC rfc that describes this header says: If the receiving MUA writes the entity to a file, the suggested filename should be used as a basis for the actual filename, where possible. It is important that the receiving MUA not blindly use the suggested filename.
The suggested filename SHOULD be checked and possibly changed to see that it conforms to local filesystem conventions, does not overwrite an existing file, and does not present a security problem. Reply to this Reply to original.
Pawel Zdziechowicz Posted on: I don't know what browser you're using and wonder why it opens separate application not embedded in browser when Content-disposition is inline, butt I know it is not THE answer: 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.
