upload progress (bytes sent)
Hi,
I've built a web services client with Apache SOAP 2.3.1 which is used for
uploading images. I would like to be able to track the number of bytes sent
for a progress bar but have not found a way of doing this. It is a
university project so I am still quite new to Java and SOAP.
I have looked through the classes and some of the sources too and have
found no clues, or just got lost! I guess I need access to the output
stream. Can anyone tell me if this is possible (it's always possible!) and
if so maybe give me some pointers.
Thanks in advance,
Barry

The nightly build of SOAP package has that method, the old versions do
not. So if you want to use it, you have to download the nightly build.

Thanks Scott and Daniel,
I am sending the images one SOAP message at a time. The web service can
handle an array of images but I have found the client implementation a
whole lot easier (error handling, etc.) sending one at a time.
I think it will make tracking upload progress a lot easier too. By
modifying HTTPUtils as Scott suggested I can count the payload bytes sent
and track progress that way, it doesn't look to difficult.
Daniel: I did a quick search and saw a reference to
SOAPHTTPConnection.getRequestCopy(), but there's no such method in the
version I'm using.

It should be legal.

Upload multiple files
Posted by Daniel Zhang <zh...@clinicaltools.com>.
Scott -
This question comes after Barry White's upload question. If I have
multiple files uploaded, one way is to send each file uploaded with
seperate soap request, but I don't think it's efficient. So the other
way I think, is to create a Datahandler array, then you send all files
in this array with single soap request, I think this is more efficient.
...
DataHandler[] dhArray = new DataHandler[fileNumber];
for (int i = 0; i < fileNumber; i++) {
dhArray[i] = new DataHandler(datasource[i]);
}
...
params.addElement(new Parameter("uploadfiles",
javax.activation.DataHandler[].class, dhArray, null));
...
The key point here is "javax.activation.DataHandler[].class" legal or
illiegal for class type? Or we have to do extra effort here?
TIA,
-Daniel

Barry,
The data is actually written and read in org.apache.soap.util.net.HTTPUtils#post. You will find that the outoging data is written to the stream in just two buffers, one containing the HTTP request and HTTP headers, and the other containing the full payload. You would need to change this code to write data in chunks in a loop and call some method to update the status.

Are you tracking the image size uploaded or the whole xml stream? If
it's the image size, you can simply sum up the image sizes uploaded; if
it's the xml stream, you can
call getRequestCopy() to track the bytes. Hope this helps.
