GroovyWS is a framework which is internally using CXF. I want to make a request as follows:
<param2 xsi:type="ns2:Map">
<item xsi:type="ns2:Map">
<key xsi:type="xsd:string">param1</key>
<value xsi:type="xsd:string">param2</value>
</item>
</param2>
Currently I am trying to do this from a grails service as following:
def proxy = new WSClient("http://xyz", this.class.classLoader)
proxy.initialize()
proxy.client.invoke("call", new HashMap<String, String>())
Which gives
javax.xml.bind.JAXBException
class java.util.HashMap nor any of its super class is known to this context.
I even tried [:] and stuff but do not get it working.
Well, it's been a while since I did something like this, but I seem to remember that CXF-generated clients had a method called "create", similar to:
def mapObject = proxy.create( "ns2.Map" );
Give that a try and see if the mapObject has the methods or members you're expecting.
This is a known issue with using JAXB
The underlying problem is that your schema is ambiguous.
There are two solutions:
Use name spaces to remove any ambiguity
Resolve each Service individually into a different Java package.

(Please be kind, these are my first steps in Java EE).
I'm working with Netbeans 8.1, deploying an EJB module on a local Glassfish Server.
I have a glassfish-resource.xml with the following resource defined:
<jdbc-resource enabled="true" jndi-name="java:app/jdbc/myDataSource"
And I have a DAO class where I'm trying to inject that resource
#Named
public class SimpleDal {
#Resource(name = "jdbc/myDataSource", lookup = "java:app/jdbc/myDataSource")
private static DataSource ds ;
I have tried several ways to make this work but I always end up with NULL in the variable ds. I've been debugging and querying the Context, and I always end up with the name java:app/jdbc/myDataSource not found.
Maybe I'm not doing something right, this is my first steps on Java EE (I've always developed for PHP). Can somebody please direct me in order to avoid losing more time? Thanks
Note: I've add the #Named annotation to the SimpleDal class because I've read somewhere that in order to Injection to work, I have to be on a Bean.
So, after some time I finally found out that injection doesn't work reliably on static fields (at least on my setup). Changed the field to an instance field and It worked . Posting this answer for anyone who is facing the same situation
I have a very simple problem of DI, and wanted to know if there is a way to solve it using Ninject (or any other DI helper).
I have a Data Access interface that is implemented by several Data Sources providers, like DB, Sharepoint, CRM, etc.
I want to use Ninject to get a specific instance of the interface, based on a parameter that contains a code representing one of this implementations.
So far I know that I can do that by using named bindings , but I couldn't find a way to do the same by xml config file (Ninject.extensions.xml).
Ninject extensions xml provides a way to solve single mappings:
<module name="SomeModule">
<bind service="Game.IWeapon" to="Game.Sword"/>
<bind service="Game.IWarrior" toProvider="Game.SamuraiProvider"/>
</module>
I'd like to do a config like that, but using multiple mappings for the same interface, using a name, a code or the like.
TIA,
Milton
Just add a name property
<bind service="Game.IWeapon" to="Game.Sword" name="sword"/>
<bind service="Game.IWeapon" to="Game.Dagger" name="dagger"/>
I'm trying to bind a XML response from a WS to a set of POJO's classes using ksoap2-android.
A lot of examples on the internet treat very simple responses like this one.
In my case however, I have a lot of custom classes and they keep a reference of each other, sometimes even inside an arraylist.
Here's what i'm trying to do, i would like to bind this kind of response :
<Car number="35">
<Engine>
[...]
</Engine>
<Passenger id="1">
[...]
</Passenger>
<Passenger id="2">
[...]
</Passenger>
</Car>
To this kind of class :
public class Car {
private int number;
private Engine engine;
private ArrayList<Passenger> passengers;
}
With, if possible, only modifying POJOs files (the Simple XML annotations system is very elegant, too bad there's no equivalent to this in ksoap).
I looked into the KVMSerializable interface, but when I try to override the getPropertyInfo() method, I have no idea of what I should return in the PropertyInfo.type and how will ksoap handle ArrayLists.
I got a huge headache right now, please help me

You should read the document from ksoap 2, they have many useful examples in there.
For getting an array of complex type, you can check here
And I have used this approach to parse a complex object.
If all of them not work, you have to map field by field from soap object to your pojo.
Updated:
Thanks a lot for the 3rd link, it's very useful and I'm now able to
map custom objects. However, in the wiki page you provided, the author
is parsing an array of custom classes, wrapped in a parent element. Is
there a way to do this with inline lists like in my example ?
I have never tried it before, but I think you can combine my answer and the wiki.
First, you can try an example from wiki to implement your passengers list (extends Vector). Then you can use my approach to create a complex object with arraylist inside. The important thing is you must register your object with the response from web service. Something like this:
public class PassengerVector extends Vector<Passenger> implements KvmSerializable {
}
envelope.addMapping(NAMESPACE, "Car", Car.class);
envelope.addMapping(NAMESPACE, "Passenger", PassengerVector.class);
But I'm not sure this way can work. For a very complex object like your example, I recommend you should get data field by field by its name, as like the wiki
I'm using the resources.groovy to declare a service e.g.
aService(com.foo.OrganizationService)
so that I can tie aService to my controllers instead of using organizationService which could change in the future.
I've noticed that the OrganizationService doesn't get treated special like other services "not" declared in the resources.groovy. For example it doesn't get injected with grailsApplication, and likely a hibernateSession etc and other things I've not hit yet....
Now, I know I can manually wire in stuff to my service but I'd rather not have to maintain that...
Is there a special way to declare a service in the resources.groovy so that gets treated like another service that grails loads up?
TIA
The short answer to your question is "no".
Under the covers, Grails services are driven by some intelligent code that is referencing a specific location and expecting certain properties.
Viewing the source code (especially around the ServicesGrailsPlugin.groovy) is a good way to see the "magic" in how these are wired together.
Is there a reason you wouldn't want to use a bonafide Grails service to solve your problem? If you are expecting things like a grailsApplication, it seems like that use is pretty specific to Grails and would be a good candidate for porting over to a "true" Grails service.
Good luck!
So I've come full circle on this. This is a timing problem. Where services haven't been grails initialized yet.
Basically when you use the resources.groovy to do service wiring you run the risk of using a Service that might initialize itself e.g. afterPropertiesSet method or static initializers that use grails services (log, hibernate session, ..) that haven't been injected yet.
So... What I've turned to instead is to create my own BeanBuilder in a BootStrap.groovy file.
BeanBuilder builder = new BeanBuilder(grailsApplication.parentContext)
def bb = builder.beans {
LoginListener(com.foo.LoginListener) {
springSecurityService = ref("springSecurityService")
userService = ref("userService")
}
}
bb.registerBeans(grailsApplication.mainContext)
When I try to publish my Workspace in RAD, I get this error "Two classes have the same xml type name", probably because the same class name exists in the same package, but in two different jars. And it seems like that the #XmlType annotation needs to have distinct values for its attributes name and namespace in the sources of these classes. I tried wsdl2java available in Apache CXF, but I'm not able to make it generate this namespace attribute. I tried fiddling with the -p package option, but that's only for placing the generated sources in the specified package.
Any ideas how to generate this namespace attribute for each element encountered in the wsdl? TIA.
thanks to Daniel's anwser:
CXF JAXB JAXBEncoderDecoder unmarshalling error : unexpected element when having qualified elements
i learned there is a parameter -xjc-npa for wsdl2java which helped me.
This will add XmlType.name and XmlType.namespace annotations to the generated classes so it won't be a problem if you have same class names but in different namespaces
I ran into this for an object named "SubmitDataResponse" that I was using as a return object from my web service method named "submitData". When I tried renaming the object, the error went away. It seems to me that CXF is creating its own return object based on the method name (in this case submitData() -> "SubmitDataResponse"). You may want to try renaming the class and see if you are having the same issue. Perhaps someone can chime in with a way to keep our class named the way we want them to (probably with some annotation).
I hope this helps.
