Hi all,
i am trying to deploy a web service that accepts attachments. The method
exposed as web service is something like
*
public
**class* SubEcho {
*public* String echo(String [] msgs,String [] moreMsgs , DataHandler dh){
System.
*out*.println("Message array 1's length : " +msgs.length);
* for*( *int* i=0 ;i<msgs. length;i++){
System.
*out*.println("Message from 1," +i+" : "+msgs[i]);
}
System.
*out*.println("Message array 2's length : " +moreMsgs.length);
* for*( *int* i=0 ;i<moreMsgs. length;i++){
System.
*out*.println("Message from 2," +i+" : "+moreMsgs[i]);
}
System.
*out*.println("Attachment received : "+ dh.getName ());
* return* ("Echoed and Received");
}
And the client code is like .....
*
public
**class* TestClient_Attachment {
*public* *static* *void *main(String args1*[]){*
*try* {
* *RPCServiceClient serviceClient =
*new* RPCServiceClient();
* *Options options = serviceClient.getOptions();
* *EndpointReference targetEPR =
*new* EndpointReference*(* **
http://localhost:8080/axis2/services/EchoService);
* *options.setTo(targetEPR);
* *options.setProperty(Constants.Configuration.
*ENABLE_MTOM*, Constants.* VALUE_TRUE*);
* *String a[] = {
"a","b", "c"};
* *String b[] = {
"d","e", "f"};
* *DataHandler attachment1 =
*new* DataHandler(*new* FileDataSource("TestClient.java"));
* *QName *opEcho* =
*new* QName(" http://service.echo.my/xsd";, "echo");
* Object*[] *opEchoArgs* =
*new* Object[] { a,b,attachment1};
OMElement response = serviceClient.invokeBlocking(opEcho,
opEchoArgs);
}
*catch* (AxisFault axisFault) {
axisFault.printStackTrace();
System.*out*.println(axisFault.getFaultCode());
}
}
Runnig the client produces this exception stack trace at the server
SEVERE: Exception occurred while trying to invoke service method echo

What can be the reason behind this????
Is there any other way to send attachments (using an
RPCServiceClient....just as the one above)
Thanks,
