Stream ended unexpectedly
I have just found Apache fileUpload, to help me with the function :)
Anyway, after a lot of trial and error to try and make it work with out
it, i was unsuccessful. So i have tried fileUpload.
Everything was ok, i have my working code :
private void process(HttpServletRequest request, Picture myForm)
{
// Validate text.
boolean isMultipart =
ServletFileUpload.isMultipartContent(request);
System.out.println(isMultipart);
ServletFileUpload upload = new ServletFileUpload();
upload.setFileSizeMax(41943040); // 5 mb
// Parse the request
try {
FileItemIterator iter = upload.getItemIterator(request);
while (iter.hasNext()) {
FileItemStream item = iter.next();
String name = item.getFieldName();
InputStream stream = item.openStream();
if (item.isFormField()) {
System.out.println("Form field ");//+ name + "
with value " + Streams.asString(stream) + " detected.");
} else {
System.out.println("File field " + name + " with
file name " + item.getName() + " detected." +
item.getContentType().length());
// Process the input stream
//...
// String imageId =
request.getParameter("uploadfile");
String imageName =
request.getParameter("imageName");
if (imageName == null) {
System.out.println("Null Picture Name");
imageName = name;
}
System.out.println(item.getContentType());
// Open the remote
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
props.put(Context.PROVIDER_URL,
"localhost:1099");
Context ctx = new InitialContext(props);
extraRemote exRemote = (extraRemote)
ctx.lookup("Project/extraBean/Remote");
int fileSize = request.getContentLength();
byte[] buffer = new byte[fileSize];
int readBytes = -1;
System.out.println(request.getInputStream());
InputStream a = request.getInputStream();
System.out.println(fileSize +" " + a);
a.read();
System.out.println(buffer);
/*while ((readBytes = a.read(buffer, 0,
fileSize)) != -1) {
a.read(buffer, 0, readBytes);
}*/
but when i try and run the while loop it will run always around 2 - 4
lines and stop. Never more.
If i try and do the below it will read a lot more, if not all the image
BufferedReader reader = new BufferedReader(new
InputStreamReader(request.getInputStream()));
String line = null;
line = reader.readLine();
while ((line = reader.readLine()) != null) {
System.out.println(line);
}
But still will bring me an error in the end
[STDOUT] -----------------------------7827094435720167761855652711
[STDOUT] Content-Disposition: form-data; name="imageName"
[STDOUT] -----------------------------7827094435720167761855652711--
[STDOUT] Stream ended unexpectedly
Can someone please let me know what i am doing wrong ? IS there
something missing ? SHould i try something else ? Should i change
something ?
Shouldnt this work the way it is ?

I was trying to implement a SAAJ solution lately and I faced the same error.
The route cause in my case was because file was big and server was dropping
the connection before reading the whole file. Problem solved by increasing
the timeout.
