Hi all, I am using MTOM with Axis2. I took the MTOM
sample bundled with Axis2 and switched it around to where the client sends in
the name of the file to retrieve and the Service returns the file back to the
Client and then the client saves the file to disk (All this is done on my
desktop in windows XP). I am running axis2 WAR under JBOSS-4.03SP1. The problem I am running into is that for Zip files larger
in size than 3.4 Meg, I am not able to open the Zip files with Winzip and I get an error: Start of central directory not found; Zip
file corrupt. Possible cause: file transfer error. P.S.: The file size returned is always exact
size as the original file (looking at it via File Explorer). It works very
well for files less than 3.4 Meg (Zip files or any other files). I ran this code against a 5 Meg word file and I was able to
open it fine, so it might be only an issue with zip files. Is there a size limit somewhere that I need to
change? Anyone knows why I might be running into this issue?
Is there anything I am missing or have incorrect in my Save routine on the
client side ? I need this tool to be able to return large files from the
service, which sizewise it appears to be returning them correctly, but file is
corrupt. Here’s my Service code: import java.io.File; import java.util.Iterator; import javax.activation.DataHandler; import javax.activation.FileDataSource; import org.apache.axiom.om.OMAbstractFactory; import org.apache.axiom.om.OMElement; import org.apache.axiom.om.OMFactory; import org.apache.axiom.om.OMNamespace; import org.apache.axiom.om.OMText; import org.apache.axis2.AxisFault; public class
MTOMProtoService { public OMElement getFile(OMElement element) throws Exception {
OMElement _fileNameEle = null;
OMElement _imageElement = null;
File inputFile = null;
System.out.println("in Method getFile, OMElement
received = " +
element.toString());
for (Iterator
_iterator = element.getChildElements(); _iterator.hasNext();) {
OMElement _ele = (OMElement) _iterator.next();
System.out.println("in Method for loop in getFile,
OMElement = " +
_ele.toString());
if
(_ele.getLocalName().equalsIgnoreCase("fileName")) {
_fileNameEle = _ele;
System.out.println(" Found _fileNameEle =
" +
_fileNameEle);
}
}
if (_fileNameEle ==
null ) {
throw new AxisFault("Either Image or FileName is null");
}
String fileName = _fileNameEle.getText();
OMFactory fac = OMAbstractFactory.getOMFactory();
OMNamespace omNs = fac.createOMNamespace("http://localhost/my", "my");
OMElement data = "">"getFile", omNs);
OMElement fileOME = fac.createOMElement("file", omNs);
FileDataSource dataSource = new
FileDataSource(fileName);
DataHandler expectedDH = new DataHandler(dataSource);
OMText textData = fac.createOMText(expectedDH, true);
fileOME.addChild(textData);
OMElement fileOMEName = fac.createOMElement("fileName", omNs);
if (fileName != null) {
fileOMEName.setText(fileName);
}
data.addChild(fileOMEName);
data.addChild(fileOME);
return data; } Save in Client Code: public void save(OMElement
element) throws Exception { OMElement
_fileNameEle = null; OMElement
_fileElement = null; for (Iterator _iterator = element.getChildElements();
_iterator.hasNext();) { OMElement
_ele = (OMElement) _iterator.next(); if (_ele.getLocalName().equalsIgnoreCase("fileName")) {
_fileNameEle = _ele; } if (_ele.getLocalName().equalsIgnoreCase("file")) {
_fileElement = _ele; }
} OMText binaryNode =
(OMText) _fileElement.getFirstOMChild(); //Extracting the data and saving
DataHandler actualDH = (DataHandler)
binaryNode.getDataHandler(); // File file = new
File(desiredFileName); // desiredFileName
is the output filename to save it under. OutputStream os = new FileOutputStream(desiredFileName); actualDH.writeTo(os); os.close(); } Thanks in advance, Camille |
