I am creating a app which requires log in and register but while coding for the app I encountered a error (I am noob) can anyone please help with it
Thanks :)
Basic idea is to send the entries to login request page which forwards the details to the php using Json which verifies with the DB but encountering this error any more details if needed please comment so that I can upload and reply.
It's somewhat hard to tell from your question, but it looks like in your Login class, it is looking for an object of type Request<T> in the add() method, but you supplied it with LoginRequest (hence the error message in the second image).
To solve this problem, you need to make your class inherit from a type of Request<T> called StringRequest: you need to have something like this:
public class LoginRequest extends StringRequest {
Without this, the class implicitly chooses Object as it's super class (as all java objects do), which doesn't have the parameters you supplied.
So, where you have the following code:
LoginRequest loginRequest = new LoginRequest(Email_id, Password, responseListener);
RequestQueue queue = Volley.newRequestQueue(Login.this);
queue.add(loginRequest);
RequestQueue's method add() takes a parameter of type Request<T>. LoginRequest is not a Request<T>. This is the reason for your error. LoginRequest needs to inherit from StringRequest. This will fix both errors. If LoginRequest inherits from StringRequest, then it is-a Request<T> and then RequestQueue's method add() can except loginRequest as a parameter.

I have a servicereference with a method I need to use in a test.
The servicereference class is defined as:
public class MyServiceReference : Clientbase<IMyServiceReference>, IMyServiceReference
{
public MyServiceReference()
{
}
..... methods is then defined
}
From my testmethod I have tried both
private MyServiceReference myServiceReferenceFake = A.Fake<MyServiceReference>();
// And
private MyServiceReference myServiceReference = new MyServiceReference();
For both of these is crashes in the constructor with the message:
System.InvalidOperationException: Could not find default endpoint element that references contract.
All I need is to have a callto definition from a method in that class.
How can this be solved?
I've no experience with Clientbase, which I assume to be a System.ServiceModel.ClientBase<TChannel>,but I can make some general comments.
Since you tried first to fake a MyServiceReference, I'll assume that you're not testing that class, and you want to use it as a collaborator for the system under test. In that case, your best bet is to try faking IMyServiceReference. interfaces are very easy to fake, since they don't bring along any behaviour or baggage like faking a class does.
If you feel you really need to fake a MyServiceReference, then we have to contend with the fact that FakeItEasy will eventually call MyServiceReference(), which will call ClientBase<IMyServiceReference>(), whose documentation says
Initializes a new instance of the ClientBase<TChannel> class using the default target endpoint from the application configuration file.
Based on the error you reported, I assume that the application configuration file is not found or does not include the configuration required to create a MyServiceReference. The fact that you get the same error when you just try to instantiate a MyServiceReference directly strengthens my belief.
So I think your paths forward are either to try faking IMyServiceReference or to provide the configuration that ClientBase<IMyServiceReference> needs.
So, I am working on a class called DMFWriteExportData and trying to get it run in Batch.
I am at a point where I need to figure out a way to get rid of fieldControl and the reason being it does not let me Run the class on the server and throws an error because it is not supposed to be running on server? (not sure)
Error: "The method Dialog Control.control cannot be called from the server; use methods on the Dialog Field class instead."
-
public Object dialog()
{
DialogRunbase dialog = new DialogRunbase("#DMF372", this);
FormStringControl control;
dialogExecution = dialog.addFieldValue(extendedTypeStr(dMFExecutionId), executionId);
control = dialogExecution.fieldControl();
control.mandatory(true);
control.displayLength(24);
control.registerOverrideMethod(methodstr(FormStringControl, lookup), methodstr(DMFWriteExecutionParameters, executionIdLookup), this);
control.registerOverrideMethod(methodstr(FormStringControl, modified), methodstr(DMFWriteExecutionParameters, executionIdModified), this);
dialogdescription=dialog.addFieldValue(extendedTypeStr(description),DMFExecution::find(executionId).Description);
dialogdescription.enabled(false);
return dialog;
}
I am wondering:
If it is actually true that this class cannot be set to server
when using control.registerOverrideMethod
If yes, what would be the ideal solution to overcome this situation,
is there any way I can create custom lookups? I see there is method
called registerOverrideMethod in the DialogField class.
Any help would be appreciated.
Thanks,
Khosla
The reason why you cannot (and should) run the code above in batch is because it uses dialog controls that only exist on the client side. You should never run this kind of code on server. Please check runon property of your class and set it to called from.
However, I assume you are using RunBaseBatch. If you are on AX 2012, you should use the SysOperation framework instead.
When using RunBaseBatch, all code is on the same class. This way, you are mixing client side code (main method, dialog method etc) with the code that should run on server (run method). For this reason you should set the "runon" property of the class to CalledFrom, not Server.
You can solve this by using SysOperation which applies the Model View Controller (MVC) pattern that neatly sepperates the two.
For an introduction to SysOperation, check my blog here:
AX2012: SysOperation introduction
I'm trying to write a simple Spring Boot controller that renders a GORM instance and failing.
Here's a shortened version of my code:
#RestController
#RequestMapping("/user")
class UserController {
#RequestMapping(value='/test', method=GET)
User test() {
return new User(username: 'my test username')
}
}
I get the following error message:
Could not write JSON: No serializer found for class org.springframework.validation.DefaultMessageCodesResolver and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) ) (through reference chain: users.domain.User["errors"]->grails.validation.ValidationErrors["messageCodesResolver"]); nested exception is com.fasterxml.jackson.databind.JsonMappingException: No serializer found for class org.springframework.validation.DefaultMessageCodesResolver and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS) ) (through reference chain: users.domain.User["errors"]->grails.validation.ValidationErrors["messageCodesResolver"])
The error seems to be caused by extra properties injected by GORM. What is the proposed solution for this? Will this eventually be solved in gorm-hibernate4-spring-boot? Should I simply disable SerializationFeature.FAIL_ON_EMPTY_BEANS (I don't have a lot of experience with Jackson so I'm not entirely sure what side effects this may have)? Should I use Jackson's annotations to solve the problem? Any other options?
I've found a way to get rid of the error using this code:
#Component
class ObjectMapperConfiguration implements InitializingBean {
#Autowired
ObjectMapper objectMapper
#Override
void afterPropertiesSet() {
def validationErrorsModule = new SimpleModule()
validationErrorsModule.addSerializer(ValidationErrors, new ErrorsSerializer())
objectMapper.registerModule(validationErrorsModule)
}
}
class ErrorsSerializer extends JsonSerializer<ValidationErrors> {
#Override
void serialize(ValidationErrors errors, JsonGenerator jgen, SerializerProvider provider) {
jgen.writeStartObject()
jgen.writeEndObject()
}
}
Obviously this solution is far from perfect as it simply nukes all validation errors but right now it is good enough for me. I am pretty sure the Spring Boot team will have to address this issue eventually as the GORM objects are also being serialized with some internal Hibernate properties like attached. I'm not accepting this answer as it is not an acceptable solution for most scenarios, it basically just squelches the exception.
This did not work for me.
So I used this instead and the error disappeared.
#JsonIgnoreProperties(["errors"])
I'm using springBootVersion '1.4.1.RELEASE' with gorm & hibernate5:
compile("org.grails:gorm-hibernate5-spring-boot:6.0.3.RELEASE")
I am having to include the following at the top of each domain class in order to use them in a client response (i.e. json serialization using jackson):
#JsonIgnoreProperties(["errors", "metaClass", "dirty", "attached", "dirtyPropertyNames"])
When using springBootVersion '1.3.5.RELEASE' I was able to get away with:
#JsonIgnoreProperties(["errors"])
This is trending in the wrong direction :)
I have two classes org.my.ClassA and org.my.ClassB both classes are in the same package org.my in the WEB-INF/src in the same database.
ClassA has the method public add(org.my.ClassB newB){...}.
In SSJS I have a code block in which I call ClassA.add(ClassB) which normally works fine. Until some unknown point where the Server can't see that org.my.ClassB === org.my.ClassB and it returns the error (message translated from German maybe looks different in English version):
error calling method 'add(org.my.ClassB)' in java-class 'ClassA'.
'org.my.ClassB' is incompatible with 'org.my.ClassB'.
and it points to my line in the SSJS: ClassA.add(ClassB);
What I tried so far:
First I added the line importPackage(org.my); to my SSJS Code. No luck.
I tried to add another method add(Object newB) and then cast the object to ClassB but same result. The error does not seem to come from the java class its from the SSJS code because it cant find the method with an argument of the type org.my.ClassB. But if I test the object in the SSJS code it returns org.my.ClassB.
Then I tried to add the classpath to all variables in the SSJS block like: var newB:org.my.ClassB = new org.my.ClassB(). But same result after some time the application breaks with the same error.
From my Point of view it got to do something with the caching of compiled classes, or so because if I clear the database everything works just fine again.
Hope someone has a solution on this.
This is a class loader problem.
You can find more details about the issue in the answer from Frantisek Kossuth:
See here more details: Meaning of java.lang.ClassCastException: someClass incompatible with someClass
How do I do this? If you could please kindly include the code for message map and the function itself, that would be greatly appreciated.
EDIT:
More specifically I am wondering how OnFileSave() links to OnSaveDocument(LPCSTR lpszPathName)
How does OnFileSave get lpszPathName?
You don't need to do anything special to override OnSaveDocument(...) it's already a virtual function in CDocument, so your derived class can just declare virtual BOOL OnSaveDocument(LPCTSTR lpszPathName); in it's header, then implement it in the document. Nothing is needed in the message map. OnSaveDocument will be called by the framework as part of OnFileSave which is a handler in the base class for ID_FILE_SAVE. The lpszPathName refers to m_strPathName when called by OnFileSafe, which is set when opening a file or by calling SetPathName. If it's empty when saving, the user is prompted for a file name.
CDocument::OnFileSave is the message handler for the Save menu command. To handle it yourself put this in your document class message map:
ON_COMMAND(ID_FILE_SAVE, OnFileSave)
and add your function:
void CYOURDOCUMENT::OnFileSave()
{
CDocument::OnFileSave();
}
To see everything it does put a breakpoint in your function and start single-stepping.
