Hi,
When I send a simple string argument using a jax-ws (2.0 RI) web service and client, I get an error when the string size is bigger than a certain size. It only happens with the Provider (PAYLOAD) service interface,
it does not happen with a Provider (MESSAGE). The following client code
package test;
import org.test.TestPortType;
import org.test.TestService;
public class Client {
public static void main(String[] args) {
new Client().run();
}
public void run() {
TestPortType test = (new TestService()).getTestBinding();
String arg = "";
for(int i=0;i<12153;++i) {
arg += "a";
}
System.out.println(test.test(arg));
}
}
gives the following exception on the Tomcat 6.0 server:

when using the following Provider:
package test;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.Marshaller;
import javax.xml.transform.Source;
import javax.xml.transform.dom.DOMResult;
import javax.xml.transform.dom.DOMSource;
import javax.xml.ws.BindingType;
import javax.xml.ws.Provider;
import javax.xml.ws.ServiceMode;
import javax.xml.ws.WebServiceProvider;
import org.test.TestResponse;
@WebServiceProvider(
portName="TestPort",
serviceName="TestService",
targetNamespace="http://test.org",
wsdlLocation="WEB-INF/wsdl/test.wsdl"
)
@BindingType(value="http://schemas.xmlsoap.org/wsdl/soap/http")
@ServiceMode(value=javax.xml.ws.Service.Mode.PAYLOAD)
public class TestProvider implements Provider<Source> {
@Override
public Source invoke(Source arg0) {
try {
JAXBContext jaxbContext = JAXBContext.newInstance("org.test");
Marshaller marshaller = jaxbContext.createMarshaller();
TestResponse response = new TestResponse();
response.setOut("OK");
DOMResult domResult = new DOMResult();
marshaller.marshal(response, domResult);
return new DOMSource(domResult.getNode());
} catch (Exception ex) {
ex.printStackTrace();
}
return null;
}
}
If I decrease the string size with just one, it all works fine. I am using the following wsdl, sun-jaxws.xml, and ant build script (I copy all jax-ws RI 2.0 libraries to the WEB-INF/lib directory.
