Java EE (Java Enterprise Edition) General Discussion

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?
