hi,
my users use a formular similar to this to upload text and a file, note
the ISO-8859-1 encoding!
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Strict//EN"
"
http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-88591-"">
<title>Insert title here</title>
</head>
<body>
<form action="
http://localhost/Servlet/setData" method="post"
enctype="multipart/form-data" accept-charset="ISO-88591-" >
<table>
<tr><td>aID</td><td><input type="text" name="aID" value="130" /></td></tr>
<tr><td>data</td><td><input type="file" name="data"/></td></tr>
<tr><td><input type="submit" /> </td></tr>
</table>
</form>
</body>
</html>
on the server the resource processing the request looks like below (i
stripped it down heavily)
@Path("/setData")
public class SetAssetResource {
@POST
@Consumes("multipart/form-data")
public Response setAsset(final FormDataMultiPart mimeMultipartData) {
try {
final FormDataBodyPart aIdField = mimeMultipartData.getField("aID");
String aID = encode(aIdField.getValueAs(byte[].class));//string ok,
even w/ umlauts
...
final FormDataBodyPart data = mimeMultipartData.getField("data");
String fileName = null;
InputStream inputStream = null;
File file = null;
if (data != null) {
final FormDataContentDisposition cdp =
data.getFormDataContentDisposition();
fileName = cdp.getFileName();//already broken
fileName = encode(fileName.getBytes(ENCODING));//still broken
...
inputStream = data.getValueAs(InputStream.class);
...
final FileOutputStream fileOutputStream = new FileOutputStream(file);
final byte[] buffer = new byte[8192];
while (inputStream.read(buffer) != -1) {
fileOutputStream.write(buffer);
}
fileOutputStream.flush();
fileOutputStream.close();
inputStream.close();
}
...
return Response.status(status).build();
} catch (final IllegalStateException ex) {
return Response.status(Status.INTERNAL_SERVER_ERROR).build();
}
}
private String encode(final byte[] fieldValue) {
return new String(new String(fieldValue, ENCODING).getBytes(), UTF8);
}
private final static String UTF8 = "UTF-8";
private final static String ENCODING = "ISO-8859-1";
}
the problems start, when umlauts are used in either text fields or the
file name.
for the textfields i found a solution (or rather workaround, imo) by using
getValueAs(byte[].class) and converting that byte[]
new String(new String(fieldValue, ENCODING).getBytes(), UTF8);//fieldValue
is the byte[]
but this will not work for the fileName of the attached file. here, the
string is already broken when it comes into my realm.
checking the string reveals that all umlauts already are broken and
converted to the same symbol (usually displayed as either a diamond shaped
thingumabob with a question mark or just a question mark) even on byte
level (all umlaut chars have the same byte value).
i tried a lot of stuff and searched the web, but there's no solution to be
found.
simple question: how do i get the file name to be displayed correctly in
the abvove setup?
please, answer to my address to, since i cannot subscribe to this list (on
java.net there's just some kind of error).
thanks in advance
