Hi folks,
i have a strange problem:
I use the http-client for data transmission between two servlets.
Before that i used HttpUrlConnection. With HttpUrlConnection i could transmit
quite large files.
Now i completely converted my application to http-client.
The file transmission still works, but unfortunately only for a very small file
size.
If i exceed this limited file size (just a few KB) i get the following apache
error:
request failed: URI too long (longer than 8190)
Google now tells me, that this only happens using the "GET" method, because
with GET the length of an URL is limited.
BUT:
I don't use the Get-method, instead i use the post method:
Code:
protected String sendRequest(String urlParams) {
String answer = null;
HttpClient httpClient = new HttpClient();
if(networkParams.isUseProxy()) {
httpClient.getHostConfiguration().setProxy(networkParams.getProxyHost(),
networkParams.getProxyPort());
logger.info("we DO use a proxy: host:" + networkParams.getProxyHost()
+ "Port: " + new Integer(networkParams.getProxyPort()).toString());
}
if(networkParams.isUseProxyCredentials()) {
httpClient.getState().setProxyCredentials(
new AuthScope(networkParams.getProxyHost(),
networkParams.getProxyPort()),
new
UsernamePasswordCredentials(networkParams.getProxyUserName(),
networkParams.getProxyUserPassword()));
}
String url = networkParams.getRemoteProtocoll() +
networkParams.getRemoteDestinationAdress() +
":" +
networkParams.getRemoteDestinationPort() +
networkParams.getRemoteDestinationPath();
HttpMethod method = new PostMethod(url);
method.setQueryString(urlParams);
try {
int statusCode = httpClient.executeMethod(method);
if (statusCode != HttpStatus.SC_OK) {
logger.error(OutputConstants.ERR_WRONG_RESPONSE +
CommonOutput.LOG_SPACER + statusCode);
return null;
}
answer = method.getResponseBodyAsString();
} catch (HttpException e) {
logger.error(e.getMessage());
logger.error(e);
return null;
} catch (IOException e) {
logger.error(e.getMessage());
logger.error(e);
return null;
}
finally {
method.releaseConnection();
}
return answer;
}
This code part should be the relevant one:
Code:
HttpMethod method = new PostMethod(url);
I don't get it, everything seems to be fine as far as i can tell?
The Apache configuration can not be the problem, because i didn't change it and
when i used HttpUrlConnection with "POST" the transfer of bigger files was no
problem. This seems to an http-client problem?
Does anybody see whats going wrong here?
