Hi,
I have been trying to implement a simple client to upload a file to a servlet. The
code I use is pretty basic (summarized below). I find that it works for files that
are sufficiently small (<128 K) but gives the following error for larger files:
14 ao�t 2003 10:19:55 com.vigis.designfilereplication.Replicator postReplicationRequest

My client is running on Java 1.4.2 under windows xp sp1. In the case where the post
fails, I don't think that it arrives at my server (i.e. my servlet does not start
running the getPost() method). My server is a servlet running under tomcat 4.1.x
using the com.oreilly.servlet.MultipartRequest API to handle the upload. This servlet
has be used extensively with multipart posts originalating from Internet Explorer, so
there should be no problems with it.
Here is a cleaned up version of the code I am executing:
MultipartPostMethod post = new
MultipartPostMethod("http://alsace/vwjserv/accept/dea93";);
HttpClient client = new HttpClient();
client.setConnectionTimeout(5000);
UsernamePasswordCredentials credentials = new
UsernamePasswordCredentials("-----","-----");
client.getState().setCredentials("realm","host",credentials);
post.setDoAuthentication(true);
try {
File archive1 = new File("c:/test.txt");
post.addParameter("VIGIS_ULD00",archive1);
} catch (FileNotFoundException e1) {
...
}
post.addParameter("instant",Long.toHexString(this.instant.getTime()));
int statusCode = -1;
int retryCount = 0;
boolean retry = true;
while (retry) {
try {
statusCode = client.executeMethod(post);
retry = false;
} catch (HttpRecoverableException hrx) {
...
} catch (HttpException e) {
...
} catch (IOException e) {
...
}
}
I think the code is pretty clean, but I am obviously missing a parmeter or something.
Any help would be appreciated.
Thanks in advance,
Dennis.
