I'm trying to run a fhir search using the following code;
FhirContext ctx = FhirContext.forDstu2();
ctx.getRestfulClientFactory().setConnectTimeout(2000000);
IGenericClient client = ctx.newRestfulGenericClient("http://localhost:1080/hapi-fhir-jpaserver-example/baseDstu2");
Bundle results = client.search().forResource(Basic.class).returnBundle(ca.uhn.fhir.model.dstu2.resource.Bundle.class).execute();
However when it runs, it always throws the exception 'FhirClientConnectionException' which is caused by the exception 'SocketTimeoutException'. Am I to assume that this is the server timing out, and not my local connection, since I set my local to 2000000?
How do I go about fixing thing? I'm using HAPI in it's out of the box config, and it times out searching through a relatively small amount of resources within about 10-15 seconds.
Try setSocketTimeout() instead.
Like this:
FhirContext ctx = FhirContext.forDstu2();
ctx.getRestfulClientFactory().setSocketTimeout(200 * 1000);
IGenericClient client = ctx.newRestfulGenericClient("http://localhost:1080/hapi-fhir-jpaserver-example/baseDstu2");
Bundle results = client.search().forResource(Basic.class).returnBundle(ca.uhn.fhir.model.dstu2.resource.Bundle.class).execute();
v3 example:
serverBase = "http://hapi.fhir.org/baseDstu3";
ctx = FhirContext.forDstu3();
ctx.getRestfulClientFactory().setSocketTimeout(200 * 1000);
// Create the client
client = ctx.newRestfulGenericClient(serverBase);
I found the answer reading source code here: https://github.com/jamesagnew/hapi-fhir/blob/master/hapi-fhir-jpaserver-base/src/test/java/ca/uhn/fhir/jpa/provider/dstu3/ResourceProviderDstu3Test.java#L1710

I have been working on a WCF web service, which is used by a mobile app that would send some data to it and save to DB.
One of the test case is that we try to append 2 (or more) records in the app, and the service is called to do a batch insert / update action.
Everything goes fine when I test using localhost, but when we test it using production server, only
the first record is saved, while the other record triggers the error message
Unable to determine a valid ordering for dependent operations...store-generated values.
I have no idea what is the cause and how to solve it. I have done some research and I am quite sure that the related model/DB table has NO circular dependency or self dependency.
Below is a snippet of the web service:
public void submit(List<SubmissionParameter> param){
using (var context = ObjectContextManager.AuditEnabledInstance){
foreach (var item in param){
ReadingSubmission readingSubmission = context.ReadingSubmissions.Where(p => p.ReadingSubmissionUniqueIdentifier == item.Readingsubmissionuniqueidentifier).SingleOrDefault();
if (readingSubmission == null){
readingSubmission = new ReadingSubmission();
context.ReadingSubmissions.AddObject(readingSubmission);
}
readingSubmission.ReadingSubmissionUniqueIdentifier = item.Readingsubmissionuniqueidentifier;
readingSubmission.SystemID = item.Systemid;
readingSubmission.UserID = item.Userid;
foreach (var record in item.Readings){
SystemReading systemReading = context.SystemReadings.Where(p => p.SystemReadingUniqueIdentifier == record.Systemreadinguniqueidentifier).SingleOrDefault();
if (systemReading == null){
systemReading = new SystemReading();
readingSubmission.SystemReadings.Add(systemReading);
}
systemReading.SystemReadingUniqueIdentifier = record.Systemreadinguniqueidentifier;
systemReading.MeasurementID = record.Measurementid;
}
context.SaveChanges();
}
}
}
ReadingSubmission and SystemReading is a 1 to many relation
SubmissionParameter is just a transmission object as the mobile client will send the JSON object to this web service.
I use Telerik Fiddler to post the JSON into this web service for testing, so I am quite sure the problem is not at the mobile client side.
Any help is appreciated! Thanks!
Finally I solve the problem though I am not quite sure why it works.
I move the context.SaveChanges() out of the foreach loop then it all works again for
both localhost and production
Hope it can help someone to save some time
I'm trying to get a list of the available users from the Core Service. I spend quite some time looking at the available service methods and the most obvious seemed to be this:
TrusteesFilterData trusteesFilterData = new TrusteesFilterData
{
BaseColumns = ListBaseColumns.IdAndTitle,
IsPredefined = false,
ItemType = ItemType.User
};
XElement listTrustees = client.GetSystemWideListXml(trusteesFilterData);
However, the code throws an error when calling GetSystemWideListXml - Unable to create Abstract Class. Am I using the correct approach and, if so what am I doing wrong? If not, what should I be doing instead?
Take a look at the samples in the open source project for workflow notification
http://code.google.com/p/tridion-notification-framework/source/browse/NotificationService/NotificationService/Worker.cs
Lines 22 - 26 in the DoWork() method should do what you need - I think need to use UsersFilterData rather than TrusteesFilterData
var users = client.GetSystemWideList(new UsersFilterData { BaseColumns = ListBaseColumns.IdAndTitle, IsPredefined = false });
So this code runs in an asp.net app on Linux. The code calls one of my services. (WCF doesn't work on mono currently, that is why I'm using asmx). This code works AS INTENDED when running from Windows (while debugging). As soon as I deploy to Linux, it stops working. I'm definitely baffled. I've tested the service thoroughly and the service is fine.
Here is the code producing an error: (NewVisitor is a void function taking 3 strings in)
//This does not work.
try
{
var client = new Service1SoapClient();
var results = client.NewVisitor(Request.UserHostAddress, Request.UrlReferrer == null ? String.Empty : Request.UrlReferrer.ToString(), Request.UserAgent);
Logger.Debug("Result of client: " + results);
}
Here is the error generated: Object reference not set to an instance of an object
Here is the code that works perfectly:
//This works (from the service)
[WebMethod(CacheDuration = _cacheTime, Description = "Returns a List of Dates", MessageName = "GetDates")]
public List<MySqlDateTime> GetDates()
{
return db.GetDates();
}
//Here is the code for the method above
var client = new Service1Soap12Client();
var dbDates = client.GetDates();
I'd love to figure out why it is saying that the object is not set.
Methods tried:
new soap client.
new soap client with binding and endpoint address specified
Used channel factory to create and open the channel.
If more info is needed I can give more. I'm out of ideas.
It looks like a bug in mono. You should file a bug with a reproducible test case so it can be fixed (and possibly find a workaround you can use).
Unfortunately, I don't have Linux to test it but I'd suggest you put the client variable in an using() statement:
using(var client = new Service1SoapClient())
{
var results = client.NewVisitor(Request.UserHostAddress, Request.UrlReferrer == null ?
String.Empty : Request.UrlReferrer.ToString(), Request.UserAgent);
Logger.Debug("Result of client: " + results);
}
I hope it helps.

I'm using Adobe Stratus (now renamed to Cirrus) to build a p2p application. Inside the application, I used NetStream.onPeerConnect callback function and expected it to be triggered every time when a peer is connected. However, it always failed with my friend A while strangely friend B managed to have the function called without any problem.
I was wondering what could be the cause to this issue?
Here are how the code pieces look like.
First of all, create a NetConnection.
netConnection = new NetConnection();
netConnection.addEventListener(NetStatusEvent.NET_STATUS, netConnectionHandler);
netConnection.connect(SERVER_ADDRESS+DEVELOPER_KEY);
Secondly, create NetStream upon NetConnection successfully connected.
private function netConnectionHandler(event:NetStatusEvent):void{
switch (event.info.code){
case "NetConnection.Connect.Success":
sendStream = new NetStream(netConnection, NetStream.DIRECT_CONNECTIONS);
sendStream.addEventListener(NetStatusEvent.NET_STATUS, netStreamHandler);
var sendObj:Object = new Object();
sendObj.onPeerConnect = function(subscriber:NetStream) : Boolean {
trace("[onPeerConnect] far id: " + subscriber.farID);
return true;
}
sendStream.client = sendObj;
sendStream.publish("file");
......
Thirdly, here's how I build the connection between two peers
receivedStream = new NetStream(netConnection, farId);
receivedStream.client = this;
receivedStream.addEventListener(NetStatusEvent.NET_STATUS, incomingStreamHandler);
receivedStream.play("file");
Please help enlighten me. Thanks!
It turns out my friend A is behind a symmetric NAT. I'm thinking to setup a TURN server for us to build a successful connection.
This should be trivial, and I'm pretty sure I did it once before.
I'm trying to post data up to a server and have it bounced back to me as a file download, prompting the native browser file download box. I know the server part works just fine becasue I can post from a demo web form, but when I run the following Flex 3 code, I can't even get the request to fire.
var fileRef:FileReference = new FileReference();
private function saveXmlAsFile(event:MouseEvent):void
{
var fileRequest:URLRequest = new URLRequest();
fileRequest.method = URLRequestMethod.POST;
fileRequest.url = "http://foo.com/dataBounce";
var urlVariables:URLVariables = new URLVariables();
urlVariables.content = "Test content to return" ;
// fileRequest.contentType = "application/x-www-form-urlencoded ";
urlVariables.fileName = "test.xml";
fileRef.addEventListener(SecurityEvent.ALL, onSecurityError);
fileRef.addEventListener(SecurityErrorEvent.SECURITY_ERROR, onSecurityError2);
fileRef.addEventListener(IOErrorEvent.NETWORK_ERROR, onNetworkError);
fileRef.addEventListener(Event.COMPLETE, onComplete);
try
{
fileRef.download(fileRequest, "test.xml");
}catch(error:Error) {
model.logger.error("unable to download file");
}
}
Note, when the call to fileRef.download is called, I can't see any request being made across the network using the traditional Firebug or HTTPWatch browser tools.
EDIT: I should add that this is for < Flash Player 10, so I can't use the newer direct save as file functionality.
Any suggestions? Thanks.
You need to add fileRef.upload to trigger the upload.
Also I would move the download statement to the onComplete so the file isn't requested before it's been uploaded.
Your explanation is pretty clear, but when I look at your code, I'm feel like I'm missing something.
The code looks like you're trying to do half of the upload part and half of the download part.
I think the code you currently have posted would work to trigger a download if you set the .method value to GET. I believe you will also need to include the filename as part of the .url property.
However, to post something and then trigger a download of it, you need two separate operations - the operation to post the data and then an operation to download it, which should probably be called from the upload operation's onComplete handler.
OK, I believe I figured out one of the things that's going on.
When you don't set the URLRequest.data property, it defaults the request method to "GET".
So, the working code looks like, with the data set to the posted URL variables:
private var fileRef:FileReference;
private function saveRawHierarchy(event:MouseEvent):void
{
var fileRequest:URLRequest = new URLRequest();
fileRequest.method = URLRequestMethod.POST;
fileRequest.url = "http://foo/bounceback";
var urlVariables:URLVariables = new URLVariables();
urlVariables.content = "CONTENT HERE";
urlVariables.fileName = "newFileName.xml";
fileRequest.data = urlVariables;
fileRef = new FileReference();
fileRef.addEventListener(Event.COMPLETE, onComplete);
try
{
fileRef.download(fileRequest, "appHierarchies.xml");
}catch(error:Error) {
model.logger.error("unable to download file");
}
}
Not sure what was wrong about the request not being made before, though.
