Opening documents in JSP

[sandeepmur]

Hi,

I need to open documents (MS Word, powerpoint, excel etc..) in my webpage (jsp). The code below works but the all the documents open mixed with junk chars..

String p = "C:\\tomcat5\\webapps\\TMN\\Despesas.xls";
// String p = "C:\\tomcat5\\webapps\\TMN\\motivacao.doc";

boolean ok = true;
ok = p!=null;
if (ok) {
if (p.indexOf(".html")>-1) {
response.setContentType("text/html");
} else if (p.indexOf(".gif")>-1) {
response.setContentType("image/gif");
} else if (p.indexOf(".pdf")>-1) {
response.setContentType("application/pdf");
} else if (p.indexOf(".doc")>-1) {
response.setContentType("application/msword");
} else if (p.indexOf(".xls")>-1) {
response.setContentType("application/excel");
} else {
ok = false;
}
}
if (ok) {
try {
int l = (int) new File(p).length();
response.setContentLength(l);
byte[] b = new byte[l];
FileInputStream f = new FileInputStream(p);
f.read(b);
ServletOutputStream o = response.getOutputStream();
o.write(b,0,l);
o.flush();
o.close();
f.close();
} catch (Exception e) {
ok = false;
}
}
if (!ok) {
response.sendError(HttpServletResponse.SC_BAD_REQUEST);
}

How can I resolve this ?

TIA

The servlet may already added some other stuffs to the header or body of the outputstream. Try add

response.reset();

before

response.setContentType(...)

Did you try byam's suggestion ?

I've seen this with PDFs in the past, and found it was more a browser issue than a server issue - generally clearing the browser cache & forcing a reload sorted it.

Obviously make sure that you are actually setting the correct content type (ie your if/else construct is working correctly).

I have cleared the browser cache and have confirmed the contenttype which looks ok.. I tried out the script on another machine with the same results..

If I set the header as "attachment", I can download the file fine but unable to make it display correctly in the browser..

any other suggestions ?

TIA
