I need to bind the value returned by a certain EOperation that I've defined in my model.
Usually I perform databind using FeaturePath and Literals, but I've always done that with attributes, never with EOperation.
How can I do that?

I am providing the ability to deserialize a list of entities returned from JPA, however the list type returned from JPA is DelegatingResultList which has no default constructor.
The implementation uses proxy beans with AOP where I intercept interfaces that extend a set of interfaces to provide basic queries.
I can easily fix this by checking in my aspect if the object type is DelegatingResultList and then copy to an ArrayList, but I don't want to have to do this for every single aspect that I'm covering.
I am using the default typing to set as a property like so:
objectMapper.enableDefaultTyping(DefaultTyping.NON_FINAL, As.PROPERTY);
The json in the serialized format with my value wrapper looks like this:
{"#class":"my.wrapper.ValueWrapper",
"response": ["org.apache.openjpa.kernel.DelegatingResultList",
[{"#class":"my.entity.TaxInfoEntity","taxType":"01","taxVal":"0.07"}, ..."]]"}
I have read about using mixins and custom deserializers, but everything I've tried doesn't seem to work.
I have tried using a Mixin, but I have no reference to the ResultList property as it's not saved in the json. Not to mention it doesn't even kick in when it's trying to deserialize.
I have tried using a custom deserializer but again, this never kicks in when deserializing. Would I be correct in assuming the mixin and custom deserializer only kick in if you try to deserialize passing the class as the type?
This of course would be read only as it's a cached value. So my intention is to convert to an Arraylist instead. How would I achieve this using Jackson?
At the time of marshalling of JAXB object I want to set some defult value to the resulting XML.
I do not want to use nillable=true as it generates empty tag with unnecessary xsi:nil="true", and this is not for setting default value. Instead I want to generate the XML with some placeholder characters such as '?'.
Use case : I am going to build a tool for WebService testing. There I need to present the entire request xml to the user (Like SOAPUI).

The idea of the place holder character isn't really going to work. For example ? is an ok default value for a string, but not an int, boolean, or for most complex values (i.e. representing the nested address information for a customer). Instead you will want a value that reflects the type.
Then I would have to write large and complex reflection based code. Just assume that
that is almost not possible in my case.
This reflection code probably won't be as bad as you are imagining. A quick search will probably also reveal libraries that populate objects with "dummy" data. When hooking it up with JAXB you could leverage a Marshaller.Listener to populate the object on the before marshal event.
Following my previous question about serialization only, I'd like to go further and support JsonFormatVisitor.
I have the same requirements, that is:
I have objects of several types (interfaces).
I don't know the type of theses objets in advance.
I can't add annotations on theses types.
I can introspect all theses objets to get their state data.
Now that serialization works, I need to generate JsonSchema and hence do something like that:
SchemaFactoryWrapper visitor = WHAT?
mapper.acceptJsonFormatVisitor( mapper.constructType( Foo.class ), visitor );
JsonSchema jsonSchema = visitor.finalSchema();
String schemaString = mapper.writeValueAsString( jsonSchema );
I've implemented a SchemaFactoryWrapper that gets its expectAnyFormat called but I don't know what to do inside it. Looks like there's no schema for "any" objects.
Maybe I can hook elsewhere in jackson? Maybe it is possible to extends the whole Bean/Property introspection mechanism to support a completely different model (ie. not beans)?
I'm a bit lost, please help me find the treasure room :)
I can try to suggest some approaches that may be helpful.
First, even if you can not annotate classes directly, "mix-in annotations" can help -- this does assume static knowledge, however
Second, since schema-generation uses type detection used for serialization, you may want to register custom serializers; but this does not necessarily mean having to hand-write all. The most flexible way to register custom serializers is via Module interface (mapper.registerModule(new MyModule()); Modules can register Serializers instance which gets called when trying to locate a JsonSerializer for a type for the first time (after this, instance is cached to be re-used for other properties of same type).
This is where you could configure and return your custom JsonSerializer; but it might only need to handle schema-related callback(s) (one(s) called by schema generator).
It is also possible to extend/modify property discovery mechanism; whether this is easier depends. But the thing to look for is registering BeanSerializerModifier via Module.
It gets called during construction of BeanSerializer (general POJO serializer used unless something more specific is registered), and with it you can add/modify properties; or just replace resulting serializer altogether (and also then allows chaining of custom serializer with default one, if needed).
Every Java Swing application has some attribute like caption, priorLabel, className, accessibleName and name. These are displayed in the Locator Spy; some with values and some without values.
My question is: The way we have GetDomAttribute() method available for web applications, do we have any such method available for Java Swing applications in SilkTest?
What if I want to get the aforementioned attribute values in a java swing application even if these attributes are not having any value (in such situation, I suppose, I will get an empty string).
Please suggest!
I think the closest match for GetDomAttribute() would be the dynamic property support in Silk Test:
Use GetPropertyList() to get a list of properties available for a certain object.
Use a property name from that list with GetProperty().
If that is not sufficient, you can also use DynamicInvoke, which is documented here (also includes dynamic properties).
I have an XSD that I'd like to not change to solve the problem I'll describe below. With the XSD in it's current form, I ran into the common problem of no #XmlRootlement being generated, and used the simple binding mode solution pointed out by many to get this annotation added.
Unfortunately, this has caused some object names in the generated code to become pluralized (i.e. list/collection objects now become cars instead of car or donkies instead of donkey) which is not desirable as I'm using these objects to binding incoming requests in CXF. Is there anyway to use the simple binding mode but disable the pluralization?
