ASIHttprequest with Apache CXF Restful webservices - objective-c

Question

I am working on a project involving Apache CXF at server side providing RESTful webservice, taking in and out in JSON format. At the client side is an Mac OSX app with ASIHTTPRequest and SBJson. I had various issues in the last few days, and was not able to find out a solution.
At server side:
#Override
#POST
#Path("/testService/")
#Consumes(MediaType.APPLICATION_JSON)
public Boolean service1(SomeMetaData metaData)
{
return this.testMetaData(metaData);
}
At client side:
NSString *requestURLString = [NSString stringWithFormat:#"%#%#", serverURL, #"/webServices/rest/testService"];
NSURL *url = [NSURL URLWithString:requestURLString];
ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
[request setValidatesSecureCertificate:NO];
[request setRequestMethod:#"POST"];
[request addRequestHeader:#"Content-Type" value:#"application/json"];
NSString* jsonMetaData = [[SomeMetaData proxyForJson] JSONRepresentation];
NSMutableData *requestBody = [[NSMutableData alloc] initWithData:[jsonMetaData dataUsingEncoding:NSUTF8StringEncoding]];
[request setPostBody:requestBody];
[request startAsynchronous];
[request setCompletionBlock:^{
NSLog(#"Response: %#", [request responseString]);
}];
[request setFailedBlock:^{
NSLog(#"Failed: %#", [request error]);
}];
The JSON string generated from the metadata object is something like this:
{
"metaData":
{
"name":"test.txt",
"remoteKey":"4",
"remoteShare":"test1"
}
}
The client and server are in different physical computer but within the same LAN.
First issue:
An error domain error randomly appears in the console. There is no apparent pattern for its appearance, but it's guaranteed to show up with my first attempt.
Failed: Error Domain=ASIHTTPRequestErrorDomain Code=1 "A connection failure occurred" UserInfo=0x10013a030 {NSLocalizedDescription=A connection failure occurred, NSUnderlyingError=0x100190cf0 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1005.)"}
Second issue:
This appears to be a json parser error which I don't really understand why. The container at the server side and the client side has identical structure.
Response for getExistsFileRequest: JAXBException occurred : unexpected element (uri:"", local:"metaData"). Expected elements are <{}someMetaData>. unexpected element (uri:"", local:"metaData"). Expected elements are <{}someMetaData>.
This kind of issue appears to be only happen when I have parameters in my request. My other GET web services with no input parameter works perfectly fine.
I have been stucked on this for days. Any suggestions will be really appreciated!
In case anyone is wondering, there is a root path defined for all web services on server side, so it's not likely to be a problem in this case.
*Another edit: * Request/Response headers at server side

Answer 1

JAXBException is in this xml namespace (javax.xml.bind.JAXBException).
Are you trying to parse JSON as XML?

Answer 2

That's not JSON
{
metaData = {
name = "test.txt";
remoteKey = 4;
remoteShare = test1;
};
}
Did you mean :
{
"metaData": {
"name":"test.txt",
"remoteKey":"4",
"remoteShare":"test1"
}
}
(If you did, update your question and I'll delete this answer ;)
