HTTPClient and Progressbar.

[crazytazo]

PostMethod filePost = new PostMethod(ui.value.getStrEIP());
filePost.getParams().setBooleanParameter(HttpMethodParams.USE_EXPECT_CONTINUE,
true);

try {
Part[] parts = {
new StringPart("FILENAME", file.m_File.getName()),
new StringPart("DIRFLAG", String.valueOf(0)),
new StringPart("FILEINDEX", String.valueOf(jfidx)),
new StringPart("FILESAVEPATH", ui.value.getStrPath()),
new FilePart(file.m_File.getName(), file.m_File)
};

filePost.setRequestEntity(
new MultipartRequestEntity(parts,
filePost.getParams()));

HttpClient client = new HttpClient();

client.getHostConfiguration().setHost(ui.value.getStrEIP(), 80);
client.getHttpConnectionManager().
getParams().setConnectionTimeout(5000);

int status = client.executeMethod(filePost);

if (status == HttpStatus.SC_OK) {
System.out.println("Upload complete, response=" +
filePost.getResponseBodyAsString());
} else {
System.out.println("Upload failed, response=" +
HttpStatus.getStatusText(status));
}

} catch (Exception ex) {
System.out.println("ERROR: " + ex.getClass().getName() + "
" + ex.getMessage());
ex.printStackTrace();
} finally {
filePost.releaseConnection();
}

this is client code using apache.HTTPClient.

it's work well, but follow line is occur blocking until get response
code from server.
int status = client.executeMethod(filePost);

How to check writing bytes in this modules?
The bytes are need to represnt progressbar.

How [should I] check writing bytes in this module?
The bytes are need[ed] to repres[e]nt progress.

Consider using a SwingWorker:

There's a nice prime number example here with a JProgressBar:

This is not what you seem to think it is.
status is a http response code and is, of course,
is blocking.
Here is a list of response codes if you are interested

The bytes are need to represnt progressbar.

One way to do this is shown on this page which
happens to cover performance optimization
http://hc.apache.org/httpclient-3.x/performance.html
In particular I think something like this would work

HttpClient httpclient = new HttpClient();
GetMethod httpget = new GetMethod("http://www.myhost.com/");
try {
httpclient.executeMethod(httpget);
Reader reader = new InputStreamReader(
httpget.getResponseBodyAsStream(),
httpget.getResponseCharSet());

/*get the response byte by byte and update your progress bar
after each response
*/
} finally {
httpget.releaseConnection();
}

Thanks rabbits77.

Your code is GET method.
Problem is POST method.

I have solved this problem by override FilePart.sendData(OutputStream
out)

Thanks John.
It's very good!

you could also read whatever is available then update progress.
