This worked for me, but caveats:
haven't tested in awhile
there may be better ways to do this
====
/**
* @return DataHandler for converted file
*/
public DataHandler getConversionFromExtraction(String outputFormat,
String extractionUrlString, String fileName)
throws ServiceException {
int numColumns;
String[] columnNames;
String[] columnDataTypes;
String[] dataElements;
try {
URL url = new URL(extractionUrlString);
URLConnection urlConnection = url.openConnection();
// set up connection to request gzip compression
urlConnection.setRequestProperty("Accept-Encoding", "gzip");
urlConnection.connect();
InputStream inputStream = urlConnection.getInputStream();
if ("gzip".equals(urlConnection.getContentEncoding())) {
inputStream = new GZIPInputStream(inputStream);
}
ExtractionParser extractionParser = new
ExtractionParser(inputStream);
inputStream.close();
String errorMessage = extractionParser.getErrorMessage();
if (errorMessage != null) {
// byte data[] = errorMessage.getBytes();
// DataSource dataSource = new
ByteArrayDataSource(data,
"text/plain");
// return new DataHandler(dataSource);
return new DataHandler(errorMessage, "text/plain");
}
numColumns = extractionParser.getNumColumns();
columnNames = extractionParser.getColumnNames();
columnDataTypes = extractionParser.getColumnDataTypes();
dataElements = extractionParser.getDataElements();
} catch(IOException ioe) {
// byte data[] = ioe.toString().getBytes();
// DataSource dataSource = new ByteArrayDataSource(data,
"text/plain");
// return new DataHandler(dataSource);
return new DataHandler(ioe.toString(), "text/plain");
}
DataHandler dataHandler = getConversion(outputFormat, numColumns,
columnNames, columnDataTypes,
dataElements, fileName);
return dataHandler;
}

and the proxy ...
====

String extractionUrlString, String fileName)
throws ServiceException, IOException {
DataHandler dataHandler;
try {
Service service = new Service();
Call call = (Call) service.createCall();
call.setTargetEndpointAddress(serviceURL);
call.setOperationName(new QName("urn:conversion",
"getConversionFromExtraction"));
call.addParameter("outputFormat",

call.addParameter("extractionUrlString",

} catch (Exception e) {
throw new ServiceException(e.toString());
}
return dataHandler;
