Download problem with JSF: Cannot open PDF-file after opening WORD-file

Question

Hello,
I have a JSP (created with Java Studio Creator) which displays a table with links to different files. Some links open PDF-documents, other for instance DOC-files (msword). I download the file as follows:
public String downloadFile(String fileName) {
try {
int dotIndex = fileName.lastIndexOf('.');
String fileExtension = "";
String contentType = "";
if(dotIndex > 0) {
fileExtension = fileName.substring(dotIndex+1, fileName.length());
contentType=CONTENT_TYPES.get(fileExtension.toUpperCase()).toString();
if(!fileExtension.equals("") && !contentType.equals("")) {
// method that reads file to the byte array
byte[] fileContent = getContentOfFile(new File(fileName));
FacesContext faces = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse) faces.getExternalContext().getResponse();
response.setContentType(contentType);
response.setContentLength(fileContent.length);
response.setHeader("Content-disposition", "inline; filename=\""+fileName+"\"");
try {
ServletOutputStream out;
out = response.getOutputStream();
out.write(fileContent);
} catch (IOException e) {
e.printStackTrace();
faces.responseComplete();
catch(Exception ex) {
return ("!!!ERROR: downloadFile(fileName) - Could not completely download file "+ fileName + ex.getMessage());
return "";
contentType is application/pdf if it`s a PDF-file or application/msword if it`s a word-file.
fileName contains the full file path.
link-properties:
<ui:hyperlink action="#{showOriginalPDF.hyperlinkShowPDF_action}" binding="#{showOriginalPDF.hyperlinkShowPDF}"
id="hyperlinkShowPDF" immediate="true" onClick="testSubmit()" target="_blank" text="#{currentRow.value['display']}"/>
and the code of the JS-function testSubmit() (without this function I couldn�t get the right row selection in the hyperlink-table):
function testSubmit() {
document.getElementById('form1').submit();
return false;
All pdf-links are working fine and the correct document is displayed in a new browser window. but if I open a WORD-document and after that I click on another link to a pdf-file, the WORD-file is loaded again in the new window. Only if I close the window which contains the WORD-document, I can download the correct pdf after that.
Is something wrong with the response header (I tried "attachment" instead of "inline" too but without effect)?
Can anybody help?

More than you asked for but good stuff. Permissions is buried in there somewhere.

"Try Disk Utility" (modified from [http://support.apple.com/kb/TS1417])
1. Insert the Mac OS X Install disc that came with your computer (Edit: Do not use this disc if it is not the same general version as what you have currently on your computer, e.g. use a Tiger disc for a Tiger drive, not a Panther disc), then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.
Then boot in Safe Mode, (holding Shift key down at bootup; takes longer to boot this way so be patient), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
