Hi,
Not sure if you can change your API but when I deal with very large data
sets on SOAP, I pass the data as a string in a single element. The string
is Base64 encoded zip of the original string
My function I use:
public static String zip(String uncompressed) {
if (uncompressed == null || uncompressed.isEmpty()) {
return uncompressed;
}
GZIPOutputStream gzip = null;
try {
ByteArrayOutputStream out = new ByteArrayOutputStream();
gzip = new GZIPOutputStream(out);
gzip.write(uncompressed.getBytes());
gzip.close();
return new
String(org.apache.commons.codec.binary.Base64.encodeBase64(out.toByteArray()),
"ISO-8859-1");
} catch (Exception e) {
myLogger.warn("Error zipping: ", e);
return "";
} finally {
if (gzip != null) {
try {
gzip.close();
} catch (IOException ex) {
myLogger.warn("Error zipping: ", ex);
}
}
}
}
then on the client:
public static String unzip(String compressed) {
if (compressed == null || compressed.isEmpty()) {
return compressed;
}
try {
byte[] b =
org.apache.commons.codec.binary.Base64.decodeBase64(compressed.getBytes("ISO-8859-1"));
ByteArrayInputStream in = new ByteArrayInputStream(b);
GZIPInputStream gzip = new GZIPInputStream(in);
return parseStreamToString(gzip, "ISO-8859-1");
} catch (Exception e) {
myLogger.warn("Error unzipping: ", e);
return "";
}
}
public static String parseStreamToString(java.io.InputStream is, String
encoding) throws Exception {
try {
return IOUtils.toString(is, encoding);
} finally {
is.close();
}
}
