[jira] Created: (AXIS2-2743) OutOfMemory error returning large xml
OutOfMemory error returning large xml
-------------------------------------
Key: AXIS2-2743
URL: https://issues.apache.org/jira/browse/AXIS2-2743
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Affects Versions: 1.2
Environment: Windows XP
Reporter: Tammy Dugan
Attachments: TestAxis2ReturnDataset.java
When I try to return 270 MB of xml from an axis2 service, I get an OutOfMemory error. I wrote my own CustomDataSource and the error occurs in the following serialize method:
public void serialize(XMLStreamWriter xmlWriter) throws XMLStreamException
{
XMLStreamReader reader = null;
StreamingOMSerializer serializer = new StreamingOMSerializer();
reader = getReader();
System.out.println("before out of memory error");
serializer.serialize(reader, xmlWriter);// OutOfMemory error here
System.out.println("after out of memory error");
xmlWriter.flush();
}
If I run the serialize locally and create my own xmlWriter, there is no error. However, if the serialize gets called from an axis2 service, an OutOfMemory error occurs. Because of this, I really think that axis2 is using a writer as input to XMLStreamWriter that is buffering all the data. It shouldn't be doing that.

------------------------------------
I think I have a workaround. I can turn off MTOM for specific services. For my purposes, services that produce lots of xml don't have attachments.

------------------------------------
I traced through the code and this is what I found:
// line 59 in MTOMXMLStreamWriter (format.isOptimized buffers all the output xml in a StringWriter)
public MTOMXMLStreamWriter(OutputStream outStream, OMOutputFormat format)
throws XMLStreamException, FactoryConfigurationError {
this.format = format;
this.outStream = outStream;
if (format.getCharSetEncoding() == null) //Default encoding is UTF-8
format.setCharSetEncoding(OMOutputFormat.DEFAULT_CHAR_SET_ENCODING);
if (format.isOptimized()) {
bufferedSOAPBody = new StringWriter();
xmlWriter = StAXUtils.createXMLStreamWriter(bufferedSOAPBody);
} else {
xmlWriter = StAXUtils.createXMLStreamWriter(outStream,
format.getCharSetEncoding());
}
}
// line 415 in OMNodeImpl (makes the XMLStreamWriter a MTOMXMLStreamWriter)
public void serializeAndConsume(OutputStream output, OMOutputFormat format)
throws XMLStreamException {
MTOMXMLStreamWriter writer = new MTOMXMLStreamWriter(output, format);
internalSerializeAndConsume(writer);
writer.flush();
if (format.isAutoCloseWriter()) {
writer.close();
}
}
//line 140 CommonsHTTPTransportSender (sets format.doOptimize to true since I'm using MTOM
public InvocationResponse invoke(MessageContext msgContext)
throws AxisFault {
try {
OMOutputFormat format = new OMOutputFormat();
// if (!msgContext.isDoingMTOM())
msgContext.setDoingMTOM(HTTPTransportUtils.doWriteMTOM(msgContext));
msgContext.setDoingSwA(HTTPTransportUtils.doWriteSwA(msgContext));
msgContext.setDoingREST(HTTPTransportUtils.isDoingREST(msgContext));
format.setSOAP11(msgContext.isSOAP11());
format.setDoOptimize(msgContext.isDoingMTOM());
//line 41 of MIMEOutputUtils (the writer.toString() causes the output of memory error
public static void complete(OutputStream outStream,
StringWriter writer, LinkedList binaryNodeList,
String boundary, String contentId, String charSetEncoding,
String SOAPContentType) {
try {
startWritingMime(outStream, boundary);
javax.activation.DataHandler dh = new javax.activation.DataHandler(writer.toString(),
"text/xml; charset=" +
charSetEncoding);
Why does it have to buffer all the xml to use MTOM? Can I turn off the optimization and still use MTOM? Wouldn't it work to stream the body xml and buffer the attachments so the attachments can be optimized?

This should be a self contained test case. You will need to use your own large xml file. I got the error to occur with a 270 MB file.

------------------------------------
I experimented changing the following values in axis2.xml:
<parameter name="enableMTOM" locked="false">true</parameter>
<parameter name="enableSwA" locked="false">false</parameter>
If either parameter is true, I get the OutOfMemory exception. If both are false, the 171 MB xml body transfers just fine. It looks like the attachment handling code is buffering the xml. I need MTOM enabled and to send large xml soap bodies.

I opened 2 related bugs one for RPCMessageReceiver and one for autogenerating enableMTOM flag in services.xml during wsdl2java. Thanks a ton for figuring this out.
