I'm trying to evaluate servicestack.text in tamarin project. I've created test iOS app and added to packages ServiceStack.Client 4.0.35
However it fails with exception on this simple code:
var t = new List { "a", "b" };
var s = JsonSerializer.SerializeToString (t);
The exception is in LicenseUtils, JsConfig. Do I need to purchase a license in order to evaluate it?
There are free quota restrictions on ServiceStack libraries which can be unlocked with a license key. ServiceStack's Text serializers allows evaluation for up to 20 Different Types in JSON, JSV and CSV Serializers without a license.

I have a .net6 worker service and I need the Request Telemetry OperationID set to a custom value. This value is my CorrelationID that is read from a message queue, and it's format is a guid with dashes.
TelemetryClient.StartOperation has an overload that takes an operationId, but it only works with a specific format. It will not work with my guid.
I have tried the code below, which appears to work in the debugger. However, the value that shows up in applicaiton insights is not what I set it to.
var client = new TelemetryClient();
client.Context.Operation.Id = internalId;
I have tried creating an ITelemetryInitializer. If I set the operationID in the initialize method will work. The problem here is getting the correlationID to the initializer in the correct dependency injection scope.
It seems as though this is a common scenario. I have seen where others ask the question but I have not found a suitable solution.
Has anyone solved this problem?
The problem is that since .Net 5 the default Id format is set to W3C standard instead of the Hierarchical Id format, see the docs:
Parent-Child relationships between Activities in the distributed trace tree are established using unique IDs. .NET's implementation of distributed tracing supports two ID schemes: the W3C standard TraceContext, which is the default in .NET 5+, and an older .NET convention called 'Hierarchical' that's available for backwards compatibility. Activity.DefaultIdFormat controls which ID scheme is used. In the W3C TraceContext standard, every trace is assigned a globally unique 16-byte trace-id (Activity.TraceId), and every Activity within the trace is assigned a unique 8-byte span-id (Activity.SpanId). Each Activity records the trace-id, its own span-id, and the span-id of its parent (Activity.ParentSpanId). Because distributed traces can track work across process boundaries, parent and child Activities may not be in the same process. The combination of a trace-id and parent span-id can uniquely identify the parent Activity globally, regardless of what process it resides in.
Activity.DefaultIdFormat controls which ID format is used for starting new traces, but by default adding a new Activity to an existing trace uses whatever format the parent Activity is using. Setting Activity.ForceDefaultIdFormat to true overrides this behavior and creates all new Activities with the DefaultIdFormat, even when the parent uses a different ID format.
When you set the Activity.DefaultIdFormat to ActivityIdFormat.Hierarchical you can specify any string as an operation Id as it does not have to conform to the W3C standard.
So the following code works like a charm:
protected override async Task ExecuteAsync(CancellationToken stoppingToken)
{
Activity.DefaultIdFormat = ActivityIdFormat.Hierarchical;
int index = 0;
while (!stoppingToken.IsCancellationRequested)
{
++index;
using var operation = _telemetryClient.StartOperation<RequestTelemetry>($"op{index}", $"a-b-c-{index}");
_logger.LogInformation("Worker running at: {time}", DateTimeOffset.Now);
await Task.Delay(1000, stoppingToken);
}
}
but it might break the distributed trace flow for your api controllers if you want to trace the end-to-end flow between multiple seperate applications.
Another way is to just include your own correlation Id as a custom propery:
operation.Telemetry.Properties["MessageCorrelationId"] = "xxx";
I'm trying to use resteasy-rxjava2 to provide an XML document using jaxb, within a vertx application (using a non-vertx legacy library we have). But I get:
Could not find MessageBodyWriter for response object of type:
org.jboss.resteasy.rxjava2.propagation.ContextPropagatorOnSingleAssemblyAction$ContextPropagatorSingle of media type:
application/xml;charset=UTF-8
From what I can tell, this comes down to the difference between a MessageBodyWriter and the AsyncResponseProvider that is in the resteasy-rxjava2 dependency for a Single (SingleProvider).
I have the following resteasy service definition
#GET
#Path(FdsnwsPaths.QUERY)
#Produces(MediaType.APPLICATION_XML)
#Stream
// CHECKSTYLE:OFF too many parameters
public Response getQuery(...)
How do I get resteasy to properly serve the data asynchrously, using the SingleProvider or otherwise.
The #Get method must return the Single explicitly or it doesn't work. (Can't use Response or Object). In my case, the Single contains the jaxb xml root element.
#GET
#Path(FdsnwsPaths.QUERY)
#Produces(MediaType.APPLICATION_XML)
#Stream
public Single<FDSNStationXML> getQuery(...)
Then, to make things more complicated, in order to handle specific exception types and map them to specific response status codes, I have to create a custom ExceptionMapper which creates the Response object I used to be able to create directly in the method. (in resteasy-vertx, I found no documentation on how to do this, but in my case, I am creating my own VertxRestEasyDeployment object so I can register the class of the ExceptionMapper(s) like this:
VertxResteasyDeployment deployment = new VertxResteasyDeployment();
deployment.getActualProviderClasses().addAll(providerClasses);
For reference, this is all being done with:
RestEasy 5.0.3.Final (including resteasy-rxjava2)
RxJava 2.2.20
Vertx 3.9.5
I have a requirement to get products by code without knowing catalogType. Is that possible to retrieve products without passing catalogType?
Below is the code snippet I've tried:
#Resource
private ProductDao productDao;
#Resource
private CatalogVersionService catalogVersionService;
List<ProductModel> getProductsByCode(String code) {
CatalogVersionModel catalogVersionModel = new CatalogVersionModel();
catalogVersionModel.setVersion("Online");
catalogVersionService.addSessionCatalogVersion(catalogVersionModel);
List<ProductModel> productModels = productDao.findProductsByCode(code);
}
Below is the exception am getting:
{
"errors": [
{
"message": "model CatalogVersionModel (<unsaved>) cannot be serialized due to being modified, new or removed",
"type": "FlexibleSearchError"
}
]
}
May I know how to fix for above issue?
When you create a product/variant in SAP Commerce (hybris) you must attach it to a catalog.
A catalog (CatalogModel) also have a version (usually staged or online), and the object is called a CatalogVersionModel
When you want to retrieve a product/variant, you must indicate the CatalogVersionModel because the product code is not a unique key to retrieve the product in the DB (you can check the Type "Product" in the backoffice and see in the XML pane that both code and catalogVersion have the value unique="true")
Now in you code there are several issue.
You should not create a catalog version but you should retrive it using a service (See DefaultCatalogVersionService)
You should use a service to retrieve your product (See DefaultProductService)
In productService implementation, you'll find two methods getProductForCode.
One with only the sku code as parameter
One with the sku code and catalogVersion as parameter
The first method actually looks like the method you want, but in fact, it uses the catalogVersion in your session. Your session will be different if you run your code in groovy or if you run your code in Java from your ecommerce website.
You can find the comment of this method below
Returns the Product with the specified code. As default the search uses the current session user, the currentsession language and the current active catalog versions (which are stored at the session in the attribute SESSION_CATALOG_VERSIONS).For modifying the search session context see FlexibleSearchQuery.
You need to specify the catalog, because it is possible to have multiple catalogs, and the same product could exist in all of those catalogs.
I recently changed my domain objects from LocalDate to ZonedDateTime. I also created a brand new play JHipster application and one play entity choosing ZonedDateTime for two class members. The test application (new) works while my existing application does not, even after going through all the code twice. I loaded CSV data using Liquibase and my listing code shows the dates properly. Here's what the data looks like in my Maven output, e.g. entrydate='2017-02-23T19:53:18-05:00[America/New_York]', transaction='Initial Balance',
When I choose to update the date-time value with the "datetime-picker" in the dialog.html, a string date time is shown in the text box but when I push "Save" I get an "Internal Server Error" and the Maven output shows:
.HttpMessageNotReadableException: Could not read document: Text '2017-02- 26T00:53:18.000Z' could not be parsed at index 23 (through reference chain: org.ciwise.blackhole.domain.GenLedger["entrydate"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: Text '2017-02-26T00:53:18.000Z' could not be parsed at index 23 (through reference chain: org.ciwise.blackhole.domain.GenLedger["entrydate"])]
Does anyone have an idea why the picker would produce String text in the text box that isn't acceptable when the HTTP PUT occurs (edit)?
My application does use Service classes but they handle the same Java domain objects as the JPA Repository classes do.
One more thing, the schema for the API shows e.g. "entrydate": "2017-02-23T21:44:04.859Z", but the actual JSON return is "entrydate": "2017-02-23T19:53:18.000-0500",
I'm hoping someone else has encountered this before.
Thanks

The answer here was to re-introduce application.yml. Inside this file it defines some Spring profiles but of most importance, it provides an option for Jackson serialization into JSON e.g.
jackson:
serialization.write_dates_as_timestamps: false
This resolved my issue.
I have different locale file for messages to user in JSF based Project.
i want to retrieve messages from all locale available in my project using Key
I am using in managed bean
String message=ResourceBundle.getBundle("com.tech.resources.messages",
new Locale(loggedInUser.getLanguage())).getString("label.hostel.room.allocated");
Instead of one String i want all messages as a array or list assosiated with this key in all resource bundles like messages.properties, messages_hin.properties etc.
As you've already figured how to get a locale-specific bundle and then get its message by key and that part thus doesn't need to be answered, your sole question basically boils down to:
How can I get all supported locales of my JSF application?
You can get all supported locales by Application#getSupportedLocales().
Application application = FacesContext.getCurrentInstance().getApplication();
Iterator<Locale> supportedLocales = application.getSupportedLocales();
while (supportedLocales.hasNext()) {
Locale supportedLocale = supportedLocales.next();
// ...
}
