This is just a guess, but I don't see where you've closed the BufferedOutputStream passed to the writeTo() method.

I am submitting to a web service and receiving an xml file in return. I am using POST b/c this is too large for a GET. If I use cURL then this works. However with HttpClient (4.1.2) and the same parameters, I am getting a truncated xml file returned. Does anyone have an idea what might be wrong? I include the test file but not the whole list of parameters I am submitting as this is a further 350Kb. import java.io.BufferedInputStream; import java.io.BufferedOutputStream; import java.io.BufferedReader; import java.io.File; import java.io.FileInputStream; import java.io.FileOutputStream; import java.io.InputStream; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.List; import javax.xml.parsers.SAXParser; import javax.xml.parsers.SAXParserFactory; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.message.BasicNameValuePair; import org.xml.sax.helpers.DefaultHandler; public class HttpClientTest { public static void main(String[] args) throws Exception { new HttpClientTest().runTest(); } public void runTest() throws Exception { List<NameValuePair> list = new ArrayList(50000); list.add(new BasicNameValuePair("db", "pcassay")); list.add(new BasicNameValuePair("dbfrom", "pcassay")); // read in ~50000 ids from file. These are existing uids in the pcassay // database. BufferedReader reader = new BufferedReader(new InputStreamReader(getClass().getClassLoader().getResourceAsStream("ids.txt"))); String line = null; while (null != (line = reader.readLine())) { list.add(new BasicNameValuePair("id", line)); } list.add(new BasicNameValuePair("term", "summary[activityoutcomemethod]")); list.add(new BasicNameValuePair("version", "2.0")); list.add(new BasicNameValuePair("email", "[email protected]")); list.add(new BasicNameValuePair("tool", "[email protected]")); System.out.println("#NameValuePairs: " + list.size()); HttpPost post = new HttpPost("http://eutils.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi";); UrlEncodedFormEntity entity = new UrlEncodedFormEntity(list); post.setEntity(entity); HttpClient client = new DefaultHttpClient(); HttpResponse response = client.execute(post); // dump to local file so we can refer to it. File file = File.createTempFile("eutils", ".xml"); System.out.println("Copying eUtils stream to: " + file); response.getEntity().writeTo(new BufferedOutputStream(new FileOutputStream(file))); InputStream is = new BufferedInputStream(new FileInputStream(file)); // attempt to parse with sax. There will be an error if only a fragment // of the xml is returned. SAXParserFactory factory = SAXParserFactory.newInstance(); SAXParser saxParser = factory.newSAXParser(); saxParser.parse(is, new DefaultHandler() { }); } } --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected] --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
