Axis - Sending large files

[Alan Richardson]

Hi again. I have hit a problem with the web service I am creating. I need to invoke a method which includes as a parameter a PDF file. Below is the code I'm using to send the file, and I can send small files (largest I have sent is 12kb), but beyond that file size I get 'java.lang.ArrayIndexOutOfBoundsException: 8192', meaning the end-of-file cannot be reached. Any ideas of what the limiting factor is here, and any possible solution?

FileDataSource ds = new FileDataSource("C:\\testPDF.pdf"); 
DataHandler pdfFile = new DataHandler(ds);
 
QName qnameAttachment = new QName("urn:WebService", "DataHandler");
 
call.registerTypeMapping(pdfFile.getClass(),qnameAttachment,JAFDataHandlerSerializerFactory.class, JAFDataHandlerDeserializerFactory.class);

call.setTargetEndpointAddress("http://localhost:8080/axis/services/WebService");
call.setOperationStyle(Style.RPC);
call.setOperationName(new QName(NAMESPACE, "addPDFFile"));
call.addParameter("code",Constants.XSD_STRING, ParameterMode.IN);
call.addParameter("pdfFile", qnameAttachment, ParameterMode.IN); 
call.setReturnType(Constants.XSD_BOOLEAN);

try
{
Boolean result = (Boolean) call.invoke(new Object[] {code, pdfFile});
return result.booleanValue();
}

Data larger than a few K should probably be sent as attachments. Look for "SAAJ" (Soap with Attachments API for Java) related info in the Axis docs.

There is a SAAJ example supplied with Axis which constructs a SOAPMessage and passes it to the call method. However I need to implement authentication I'm not sure how I would handle the security headers this way, would it mean implementing it by hand?

Presumably the code below is adding an attachment, but the same problem occurs.

Service service = new Service();
Call call = (Call) service.createCall();
call.setClientHandlers(new WSDoAllSender(),null );

AttachmentPart attachmentPart = new org.apache.axis.attachments.AttachmentPart();

attachmentPart.setDataHandler(newFile); // File attempting to send

call.setProperty(WSHandlerConstants.ACTION, "UsernameToken");
call.setProperty(WSHandlerConstants.USER, code );
call.setProperty(WSHandlerConstants.PW_CALLBACK_CLASS, " client.PWCallback");
call.setTargetEndpointAddress("http://localhost:8080/axis/services/WebService");
call.setOperationStyle(Style.RPC);
call.addAttachmentPart(attachmentPart);

RPCElement ele1 = new RPCElement("code");
RPCElement ele2 = new RPCElement("newFile");
 
ele2.setAttribute("href", attachmentPart.getContentId());

RPCElement rpcElement = new RPCElement("updateFile");
rpcElement.setNamespaceURI("http://localhost:8080/axis/services/WebService";

rpcElement.addChildElement(ele1);
rpcElement.addChildElement(ele2);

Boolean result = (Boolean) call.invoke(rpcElement);
