Fwd: Attachment problem
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,
Anant

Please provide the "-Ddest" an absolute path...
Eg: D:\axis2-1.1.1\samples\soapwithattachments>ant run.client -Dfile
README.txt -Ddest D:\README.txt

Hi,
Putting a byte[] instead of A DataHandler works!!!!
But one more query.....
Is there any workaround for making overloading possible in axis2.
thanks in advance,
anant

AFAIK Axis2 still does not support the deployment of POJO based
services with dataHandler parameters..
Please try putting a byte[] instead of the data handler.

There are other ways such as using Axiom & databinding. Once again I'm
not sure whether the RPCServiceClient supports it..
You can log couple of improvement JIRA's for the pojo & rpcClient
support for DataHandlers.
