6:14 a.m.
Dear all,
I'm trying to get a webservice up an running that is capable of receiving large
documents, so I decided to give MTOM/XOP a try. Although I seem to have done everything
necessary, I still get OutOfMemoryExceptions on both, client and server side.
Here is what I've done so far:
The service:
| @WebService
| @BindingType(value = SOAPBinding.SOAP11HTTP_MTOM_BINDING)
| @MTOM(enabled = true)
| @Stateless
| public class SampleService {
|
| public void sendDocument(@XmlMimeType(value = "application/octet-stream")
DataHandler document) {
|
| if (document != null) {
| try {
| InputStream in = document.getInputStream();
| File f = File.createTempFile("mtom", ".dat", new
File("/tmp"));
| if (f.exists() && f.canWrite()) {
| FileOutputStream fout = new FileOutputStream(f);
| byte[] buffer = new byte[4096];
| int rLines = -1;
| while ((rLines = in.read(buffer)) > 0) {
| fout.write(buffer, 0, rLines);
| }
| fout.close();
| in.close();
| }
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
| }
|
| }
|
Deploys fine. After doing wsconsume on the WSDL I end up with this client:
| public class TestClient {
|
| public static void main(String[] args) {
|
| if (args.length != 1) {
| System.err.println("usage: java -jar TestMTOM-client.jar
<fileToSend>");
| return;
| }
|
| File fin = new File(args[0]);
| if (!fin.exists()) {
| System.err.println("No such file: "+args[0]);
| return;
| }
|
| SampleServiceService service = new SampleServiceService();
| SampleService port = service.getSampleServicePort();
| SOAPBinding binding = (SOAPBinding)((BindingProvider)port).getBinding();
| binding.setMTOMEnabled(true);
|
| DataHandler handler = new DataHandler(new FileDataSource(fin));
| port.sendDocument(handler);
| }
| }
|
Logfile and final exception with DEBUG set on org.jboss and org.jboss.management after the
client was invoked with a 100MB file (and using -Xmx512m to prevent OOME on client-side):

Seems to me like it is indeed transferred using XOP and that a swapfile is generated for
the incoming request. However, afterwards on deserialization something goes wrong - I hope
the former swapped attachment doesn't get deserialized in memory at this point?
Tested with:
JBoss 4.2.3GA (default settings -Xms128m -Xmx512m)
JDK 1.5.0_14-p8
JBossWS (native) 3.1.1GA
Any ideas what I've missed?
Thanks in advance,
Max
