Code not getting rolled back for RuntimeException..
This is another configuration file which imports the DatabaseConfig
I am trying to use Nested Transactions. I have a service class calling repository class..
Both annotated with #Transactional,
In deposit, I am throwing RuntimeException, but seems it is not doing rollback
Calling transfer/ deposit methods using controller. Any suggestions would be helpful.
Complete code also available at :https://github.com/payalbnsl/SpringMvcDemo
If i don't annotate DatabaseConfig with #Configuration, transaction management seems to be not working..
Solved by adding #Configuration on top of DatabaseConfig class.

I just started learning NestJS and GraphQL. I started with a single resolver class UserResolver defined in UserModule. This class provides methods to read a list of users or a specific user. Methods are decorated with #Query(), a user.graphqlfile is provided, GraphQL is initialized in AppModule, all as described in the docs. All works well, I can get a list of users or specific user through Insomnia Tool or through Playground. I am happy!
Now I have created a second module, RoleModule. I created a role.graphql file and a RoleResolver class, I basically replicated all the work done for User but this time for Role. The GraphQL type definition for type Role as well as the Query definitions in the role.graphql file are recognized. What is not recognized are my Query() implementations in the RoleResolver class, they are not getting invoked.
If I put all these Role related #Query() definitions into the UserResolver class, these Role related queries are now getting invoked.
Is that expected behavior? Do I need to put all my GraphQL query definitions into a single class? Is it possible to spread NestJS-GraphQL resolver implementations over several modules? Am I doing something wrong? Please help.
Make sure that you import Query from #nestjs/graphql and not from #nestjs/common.
I am using jaxrs1.1 jar shipped with Websphere liberty profile 8.5 for creating REST WebService.
Lets suppose we have a method addNewProject as shown below :
If many people call this webservice method to add project concurrently. using link below , are there any concurrency issue? In servlet, each request is a separate thread , is it the same case here or should we handle concurrency by ourselves ?
endpointLink: http://somehost.com/path1/path2/addprojectdetails and POST the JSON object.
#POST
#Path("addprojectdetails")
#Consumes(MediaType.APPLICATION_JSON)
#Produces(MediaType.APPLICATION_JSON)
public Response addNewProject(ProjectDetails projectdetailsObj) {
return Response.status(200).entity("Project"+projectdetailsObj.getProjectname()+"successfully added").build();
}
I'm not sure what kind of concurrency issues you might be thinking of. The object itself can be either a singleton or request scoped (if using CDI) or a stateless session bean (if using EJB). If you're using a singleton, then you may need to be thread aware and not store state within the class.
It would probably help to understand what kind of concurrency issues you had in mind to answer more thoroughly.
I am trying to switch a hosted worker process in Azure to use xml serializer instead of the default json serializer. I have done this by implementing IWantCustomInitialization like this:
public class BusInitialization : IWantCustomInitialization
{
public void Init()
{
Configure.Instance.XmlSerializer();
}
}
However when I start the cloud solution, I get the following error:
Exception when starting endpoint, error has been logged. Reason: Type NServiceBus.Unicast.Transport.CompletionMessage was not registered in the serializer. Check that it appears in the list of configured assemblies/types to scan.
When I use no custom initialization and it goes to JsonSerializer, everything is fine. Does anyone have a suggestion where shall I look to? I use NSB 3.2.8.
thought this was fixed but I just checked, looks like in 3.2.8 the jsonserializer cannot yet be overriden easily. This has already been fixed on the dev branch but didn't get into release yet, it will be in the next one than.
If you can't wait for next release then you can work around this by replacing the AsA_Worker with your own role and role handler similar to this:
3.2.8 version https://github.com/NServiceBus/NServiceBus/blob/master/src/azure/Hosting/NServiceBus.Hosting.Azure/Roles/Handlers/WorkerRoleHandler.cs
develop version https://github.com/NServiceBus/NServiceBus/blob/develop/src/azure/Hosting/NServiceBus.Hosting.Azure/Roles/Handlers/WorkerRoleHandler.cs
Kind regards,

I wanted to try EF5 as described here: http://msdn.microsoft.com/en-us/data/jj193542
But as soon as
using (var db = new BloggingContext())
is reached an System.InvalidOperationException is thrown with additional details saying that "The type 'ConsoleApplication1.Program+Blog' was not mapped. Check that the type has not been explicitly excluded by using the Ignore method or NotMappedAttribute data annotation. Verify that the type was defined as a class, is not primitive, nested or generic, and does not inherit from EntityObject."
No database is created. I'm using VS 2012 Express for Windows Desktop and SQL Server 2012. The database explorer can connect to the local SQLExpress instance without problems.
Any ideas?
Cheers, mttmjapj
Okay, found the culprit. I unconsciously put the source for Blog and Post into the program class. Which obviously is nested and therefore can't work.
i am adding a new method into CalEventLocalServiceImpl using hook...
my code is ..
public class MyCalendarLocalServiceImpl extends CalEventLocalServiceWrapper {
public MyCalendarLocalServiceImpl(CalEventLocalService calEventLocalService) {
super(calEventLocalService);
// TODO Auto-generated constructor stub
}
public List getUserData(long userId) throws SystemException{
DynamicQuery query=DynamicQueryFactoryUtil.forClass(CalEvent.class)
.add(PropertyFactoryUtil.forName("userId").eq(userId));
List deatils=CalEventLocalServiceUtil.dynamicQuery(query);
return deatils;
}
}
liferay-hook.xml:
<service>
<service-type>
com.liferay.portlet.calendar.service.CalEventLocalService
</service-type>
<service-impl>
com.liferay.portlet.calendar.service.impl.MyCalendarLocalServiceImpl
</service-impl>
</service>
my question is how to use getUserData from jsp file.
Can anybody help me out....
i think u didn't gt my question...i want list of events based on USERID from Calendar ...to achieve this task what i need to do??
I assume getUserData() is not overridden but a new method (can't look up currently). This is not what you can do when overriding a service. Instead you'd have to add a new Service and make it available to the portal.
Remember that a customized ("hooked") jsp is running in the portal classloader, while your overloaded service is running in the hook's classloader. Thus, if you create a new service and make the service.jar available to Liferay (e.g. on the global classpath) you can call it from JSPs. The interface of Liferay services can not be extended through an overloaded service.
In case getUserData() is already in the interface (as I said I can't look up currently), you just need to call the CalendarLocalServiceUtil from your jsp and it will be delegated to your wrapper.
Just to add to Olaf's answer and comments...
if you you want to extend CalEventLocalService service with just "getUsetData" and use it in one jsp than building your own service might be overkill. Simply put your code from "getUserData" in jsp. Otherwise follow Olaf's suggestions.
