socket write error and non repeatable request entity problem
I have this code:
-----------------
DefaultHttpClient httpclient = new DefaultHttpClient();
// I want stream body, not file body
InputStream fullStream = new BufferedInputStream(new FileInputStream(...), 8192);
HttpPost method = new HttpPost("...");
MultipartEntity entity = new MultipartEntity();
InputStreamBody fullBody = new InputStreamBody(fullStream, "application/octet-stream", "full-5000");
entity.addPart("fullll", fullBody);
method.setEntity(entity);
HttpContext context = new BasicHttpContext();
HttpResponse response = httpclient.execute(method, context);
-----------
The first time I execute this code it returns HTTP CREATED (which is expected).
The second time....
...I receive on the client side:
2010-9-14 18:13:25 org.apache.http.impl.client.DefaultRequestDirector execute
INFO: I/O exception (java.net.SocketException) caught when processing request: Software caused connection abort: socket write error

and on the server side:

After I restart my IDE this problem disappears (but it should not be there in the first place).
Do constructors of objects of the httpclient lib maintain GLOBAL STATIC DATA ?????????
So what is that invalid chunk header ? Is there a problem in the multipart parser I use?
Or is there a problem with my code, or god forbid, HttpClient ?
Will this problem disappear if I use non chunked body ?
Why is it present if I am using chunked one ?
What headers can be invalid ?
How to modify them ?
Thank you.

No they do not.

Apparently Grizzly (GlassFish?) thought some of the body chunks was
malformed and dropped the connection. You can see whether or not this is
the case by using a packet sniffer or wire logging feature of HttpClient
