[JBossWS] - streaming with jbossws with small packets, or getting HttpUr
by suvigy
hi!
I'm developing a hyperterminal applet, where I'd like that the user can send data to COM ports via applet, and the COM port sends data back via web-service (streaming). Is it possible to do it with JBOSSWS? I need streaming for that. But often only few bytes (even 1 byte) comes from the COM port, I would like this even 1 byte to be flushed. I don't want any buffering.
I created a test service in that I enabled MTOM, but it's buffering, because I have to wait 10 seconds on the client side till the data arrives:
Server side, in that I simulate the hyperterminal, after each byte I wait 1 second. It should be flushed each time :
| @MTOM
| @BindingType(value=javax.xml.ws.soap.SOAPBinding.SOAP12HTTP_MTOM_BINDING)
| @WebService
| public class TestService {
| @WebMethod
| public @XmlMimeType("application/octet-stream") DataHandler getStream() {
| return new DataHandler(new DataSource() {
|
| public String getContentType() {
|
| return "application/octet-stream";
| }
|
| public InputStream getInputStream() throws IOException {
|
| return new InputStream() {
| private int count = 0;
| @Override
| public int read() throws IOException {
| if (count!=0)
| try {
| Thread.sleep(1000);
| } catch (InterruptedException e) {
|
| }
| count++;
| if (count>10)
| return -1;
| return 'a';
|
| }
|
| };
|
| }
|
| public String getName() {
|
| return "test";
| }
|
| public OutputStream getOutputStream() throws IOException {
|
| return null;
| }
|
| });
|
| }
| }
|
|
|
If there is no Binding annotation at the beginning, then the behaviour is the same
Client Side:
| public class ConsoleTest {
|
| /**
| * @param args
| */
| public static void main(String[] args) throws Exception {
| MTOMFeature feature = new MTOMFeature();
|
| TestServiceService service = new TestServiceService();
|
| TestService port = service.getTestServicePort(feature);
| Map<String, Object> ctxt = ((BindingProvider)port).getRequestContext();
|
|
| // Enable HTTP chunking mode, otherwise HttpURLConnection buffers
| ctxt.put(JAXWSProperties.HTTP_CLIENT_STREAMING_CHUNK_SIZE, 1);
|
| DataHandler dh = port.getStream();
|
| InputStream is = dh.getInputStream();
| int data;
| while ((data = is.read())>-1) {
| System.out.print((char)data);
| }
| is.close();
|
| }
|
| }
And I have to wait 10 seconds, till the result comes. I would except the data to come continuously.
I don't know if it is possible.
If not, then I would write an own servlet for that. In the real application I maintain session, so the client uses cookie, but then I would need the http client of jbossws on the client side. Can I get it somehow (What type does it have? HttpUrlConnection?)?
Thnx
George

[JBossWS] - strange: NoClassDefFoundError: org/jboss/wsf/spi/invocation/
by beligum
Hi all,
Please help me with this one: I've been trying to solve it all night.
I "patched" a fresh installed EAP-server (AS 4.2.0) (jboss developer studio) with jbossws 2.0.0 and am trying to deploy a webservices-enabled EAR.
All goes well, until I get this error:
| 03:51:26,409 ERROR [MainDeployer] Could not start deployment: file:/home/bram/Programs/jbdevstudio/jboss-eap/jboss-as/server/default/deploy/tumbolia-ear.ear/tumbolia-ejb.jar/

Any ideas?
I must say that I'm starting the server from within developer studio.
