WebService dataControls

Hi, in model i create WEbServiceDataControl.
On local i use ip like 195.......
But when i deploy ma app on server - webServices must call from 172.... ip.
My problem: i cant change ip for my dataControls. It work great on local or on server, i just want for develope on local then deploy to server, but cant.
I tryed to change ip of DC by right click on DC and click "Edit definition" and tryed to change dtaControls.dcx manualy but have no effect...

I have not connection.xml file, only DataControls.dcx When i do deploy on local server - WSdataControls running normaly, but jdbc connection for database loosing. Cannot finded, but this is other big problem of ADF with own themes on this forum.
Problem was: adf automaticly don't redeploy model to jar and get old jar. And if u change wsdl in model (dataControl.dcx) - adf don't update (redeploy jar) model.
Resolve of my problem: redeploy model in jar if needed and then do deploy (not run) on integrated WL.

Webservice Datacontrol Java files

Hi,
Is it possible to generate Java files for my Webservice DataControl? I want to have more control over it.
I tried to generate Webservice client and proxy (also in JDeveloper 10 that doesn't use annotations), but that doesn't work in Java ME 1.4.
Thanks

We're looking into this but currently there is no support for generating proxy classes. There will be some helper methods available soon to make this type of work easier.

Did you test the WSDL by
1)opening it in a browser and
2)also by running it using the HTTP Analyzer ... I'm guessing the WSDL might have issues
Also is your request and response included in the WSDL or they are referred to as separate files ?

Configure EndPoint URL in WebService DataControl and Proxy

I have created application using webservices based DataControl and WebService Proxy. I want to use config file to change the host and port for these webserviceDC and webServiceProxy.
I have referred the following link -http://blogs.oracle.com/adf/2011/02/changing_endpoint_url_for_a_web_service_data_control.html
Any links or pointers , how to do that ?
Thanks,
Rajdeep

I have created the ADF WebServiceConnection for the webproxy class generated. Then I have used the following code to use the URL's from Connections.xml -
Context ctx;
try {
ctx = ADFContext.getCurrent().getConnectionsContext();
WebServiceConnection wsc = (WebServiceConnection) ctx.lookup("GetPaymentTypesService");
getPaymentTypesPort = wsc.getJaxWSPort(GetPaymentTypesPort.class);
Issue - when i run this with in same application It works fine. But try to use this project in another application as ADF Library , it is not able to pick the connections and wsc object is comming as null.
Thanks,

Webservice Datacontrol

I have created a data control out of webservice and I have a table that uses the datacontrol. I need to create the search/query for the table. I am NOTusing business components that allows us to create Names criteria(from VO). Can we create named criteria for the web service data control?
Thanks

Hi
Can we create named criteria for the web service data control?
No. I don't see this as an option for the WS DC

ADF Mobile webservice datacontrol parameter problem

Hi, I have a method in my WS which has a List lista as input parameter when I create the datacontrol It shows Object instead of list,
how can I solve this? I cannot use List<MyBean> because this is not awolled in adfmobile
I use Jdeveloper 11.1.2.3.0
--diego10.

Hi,
1. you actually need to create an entity of the type the list objects are of. E.g. Employee to represent a list of employees
2. You access the WS DC programmatically from Java and encapsulate it in an array of Employees (to follow my sample)
3. You use a POJO data control to expose the array list
private HashMap employeeListCache = null;
     * Query all employees from a Web Service and keep the value local.
     * @return Collection of Employees
    public Employees[] getAllEmployees() {
        Employees[] emps = null;
        if (employeeListCache == null) {
            employeeListCache = _findAllEmployees();
        emps = (Employees[])employeeListCache.values().toArray(new Employees[employeeListCache.size()]);
        return emps;
private HashMap _findAllEmployees() {
        try {
            //renew all employee data
            employeeListCache = new HashMap();
            //invoke WS data control from this POJO
            ArrayList parameterNames = new ArrayList();
            ArrayList parameterValue = new ArrayList();
            ArrayList parameterTypes = new ArrayList();
            //Generic representation of a data control's data provider object. It exposes meta information about
            //the providers attributes and accessors, as well as the ability to get and set their values.
            //This interface abstracts the raw data provider object from the nature of its type of data control;
            //the raw provider can be a deserialized representation of an object returned by a SOAP or REST web
            //service call, or it can be an actual java class instance. This interface is used primarily by the
            //internals of the embedded java data control framework, however it can also be used when invoking data
            //control methods directly from application java bean code.
            GenericType employeesList =
                (GenericType)AdfmfJavaUtilities.invokeDataControlMethod("HrWSDC", null, "getEmployeesFindAll",
                                                                        parameterNames, parameterValue,

            if (employeesList != null) {
                for (int i = 0; i < employeesList.getAttributeCount(); i++) {
                    GenericType row = (GenericType)employeesList.getAttribute(i);
                    Employees employee = (Employees)GenericTypeBeanSerializationHelper.fromGenericType(Employees.class, row);
                    employeeListCache.put(employee.getEmployeeId(),employee);
        } catch (AdfInvocationException e) {
            logApplicationMessage(Level.SEVERE, "Cannot read data from Web Service \n", ""+ e.getMessage());
        return employeeListCache;

WebService DataControls programmatically construct java class en jdeveloper 11g

1. I have a data control what is a web service client to URL https:
2. JDev 11g build a model
3. I need to call this data control from java class
4. My java class simply must call a method of the web service, this method I see in the DAta Control, with the parameter and just return the String,
5. this is not a Web Application, is swing, I not have a Context
method in WS
public String ConsultaPlaca(String arg1);
How I can implement this?
Just in Java Class, not in page JSP. the java class is a library of other Java class, I need to build a file .jar

Hi Vishal,
I created the class as mentioned in the link. But when I try to test the web service, I get the following error :

Accessing Webservice DataControl in Model

hi,
i have requirement where i want to access web service data control in ADF model ...
regards
Kiran

Kiran S,
Data controls are things that make model data available to the UI, so on the surface, what you are asking for isn't possible (actually, you didn't ask for anything, just made a statement :) )
Have you considered using a web service proxy class in your model project to access the information?
Can you share a better use case that might enable someone to give a better suggestion?

How to query webservice datacontrol from bean

Hi all,
In Jdeveloper 11 I have a web-service based data-control. In order to perform some checks, I need to query that DC from within a bean. Only question is, how to do that?
If it were a 'normal' VO based DC I would use something like this:
DCBindingContainer bindings = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
DCIteratorBinding iter = bindings.findIteratorBinding("EmployeesView1Iterator");
RowSetIterator rsi = iter.getRowSetIterator();
rsi.next();
Row row = rsi.getCurrentRow();
String s = (String)row.getAttribute(1);
But in this case the String s = (String)row.getAttribute(1); returns rubbish. The method in the DC I want to call takes a parameter as input, and returns one row.
Any help would be greatly appreciated.
Arno

Hi Frank,
I don't know what it returns, but the iterator I got in my example was the methodIterator. When I call the accessorIterator it does work. So, when I call row.getAttribute("soandso"); the correct data is returned to me.

Issue: Datacontrol using webservice

Hi Gurus,
I am new to ADF technology. I have created a datacontrol using webservice and using that webservice datacontrol, i have also created a ADF page and it is successfully invoked the webservice.
But for some reason wsdl location has been changed to another server. Now the challenge is to change the wsdl location in datacontrol. I have edit the previous Datacontrol and provide the new webservice wsdl.
but it is not working now means ADF page is unable to invoke the service :(
Is there any other places to change the wsdl location. Any suggestion would be helpful to me.
Thanks in advance
Sharmistha.

How to deal with xsd:dateTime from webservice in ADF? (Frank can you help?)

I have a webservice that returns a date in the yyyy-MM-dd'T'HH:mm:ss.SSSZ format (as far as i know the default Calendar type format) specified by an xsd:dateTime. When i generate a webservice datacontrol on the service i get an entry like <Attribute Name="testDate" IsUpdateable="0" Type="java.util.Date" /> in the datacontrol xml file generated for the service (should that not be a java.util.Calendar type?). When i try to output the value on a jsf page it results in the following error:
oracle.jbo.domain.DataCreationException: JBO-25009: Can not create object of type java.util.Date with value 1994-02-01T00:00:00.000+01:00
As far as i understand adf tries to create a java.util.Date object from the webservice output 'string' which fails. The webservice is a plsql webservice generated with jdeveloper. If i change the type in the datacontrol xml file from java.util.Date to java.lang.String it prints out the entire date string but i would like to keep it a date type to be able to format the output to the dd-MM-yyyy pattern.
Any help or suggestions.....?
Kind Regards,
Andre Jochems

Andre,
sorry, for not replying earlier - missed this post obviously. I don't know whether or not the behavior you see is correct or a bug - need to investigate this first (or find somebody to invest).
However, as a work around for now you can:
Option 1: bind the UI component to a managed bean that then accesses the binding layer to access the Web Service Data Control. This way you can work with Strings and just create a java.util.Date object for the component using the SimpleDate formatter
Option 2: Use a Web Service proxy and a JavaBean DataControl to access the proxy. This allows pre-processing of the Web Service response, e.g. handling the Date
Note that this is just for possible work around until I find the time to look at this. However, if this is a blocking issue for a production application then I suggest to contact customer support for immediate help

Dependent combo boxes using webservice

Hi All,
I'm trying to create a depended combo boxes using af:selectOneChoice, using webservice datacontrol. When i try to change the value of the first combo box which has hard coded values (eg. Continent), The depended combo box (eg.Country) is empty. (which is returned via webservice) When i again change the value of the first combo box, I get the corresponding values(Countries) generated. The very first time when a value is selected is not binded to the model. Why is this happening and how to overcome this issue. I tried using the value change listener and assigned the current value to binding but there was no change in the behaviour.

Thanks for your response Frank. The Sample worked fine. But when i try to implement the same i ran into issues.
First, I created a combo box for continents and a managed bean.
<af:selectOneChoice label="Region" id="soc1" autoSubmit="true"
                              valueChangeListener="#{locateBean.setRegion}">
            <af:selectItem label="Asia" value="Asia" id="si3"/>
            <af:selectItem label="Europe" value="Europe" id="si2"/>
            <af:selectItem label="NA" value="NA" id="si1"/>
          </af:selectOneChoice>Then I created a combo box for countries using the webservice data control.
          <af:selectOneChoice value="#{bindings.Country.inputValue}"
                              label="Country"
                              required="#{bindings.Country.hints.mandatory}"
                              shortDesc="#{bindings.Country.hints.tooltip}"
                              id="soc2" partialTriggers="soc1">
            <f:selectItems value="#{bindings.Country.items}" id="si4"/>
          </af:selectOneChoice>In the managed bean as
    public void setRegion(ValueChangeEvent event) {
        this.region = (String)event.getNewValue();
    }1. When i run and select an continent, the values are not getting populated in the country combo box. If i refresh the page or select another value for the continent, then its is getting populated.
2. When i tried to execute the operation manually at pagedef on value change event,
        OperationBinding operBinding = getBindings().getOperationBinding("GetCountryList");
        operBinding.execute();I'm getting an warning as <FacesCtrlListBinding> <getInputValue> ADFv: Could not find selected item matching value Afghanistan of type: java.lang.String in the list-of-values.Why the value binded to the managed bean or model is not getting updated for the first time. Is this the expected behavior.

EJB 3.x datacontrol in JDeveloper.

Hello.
Does anyone know if the next release of JDeveloper will support the making of EJB 3.x datacontrols for ADF? For the time being, it seems that JDeveloper only supports creation of EJB 2.1 datacontrol and WebService DataControl. My ejb uses eclipselink, so I want to develop adf-pages with datacontrols from my existing ejb.
Thanks a lot!

Thanks for quick reply! I''m sorry if my explanation wasn't good enough. I'm aware of the possibilty to create EJB 3.0 datacontrols as long as they are developed within Jdeveloper. My EJB 3.0 - remote interface is already developed and deployed on a Glassfish 3.1 server. The 'New' - gallery in Jdeveloper lets you create a Webservice datacontrol from a wsdl and an EJB 2.1 datacontrol from an existing jar. I want to create a EJB 3.0 datacontrol from an existing jar, but can't find the right way to implement this. I've managed to create WS and EJB2.1 datacontrols, but my bean is already implemented and fully functional as a 3.0.
I'm using JDeveloper 11.1.2.1.0, btw.
PS! If I'm not mistaken, the tutorials mentioned develops the EJB 3.0 from scratch. Mine is already developed in NetBeans with Maven and deployed on a GF 3.1.
Regards.

Hi,
Did you configure your application module to use a JDBC data source? To do this, right-click the app module in the navigator, select Configurations and in the dialog that comes up change the connection type to JDBC Data Source and enter your data source name - which should be the same as the data source you created on the weblogic server.
Also, I do suggest you create an EAR file - this is what we've tested and certified with. You can find more details in the deployment chapter of the fusion developer's guide: http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/deployment_topics.htm#CHDJJDDG.
Hope this helps

Is it possible the query in view object is dynamic?

Is it possible the query in view object is dynamic?
Generally, make the column list dynamic.
I think this is related to whether view object can be assembled at runtime based on a dynamic cursor in a procedure?
I ask this because I would like to know how we can use OA framework to simulate crosstab workbook in Discoverer?
Anybody has some clues, please advise.
Thanks.

Hi Shay,
Let me tell you briefly... I am sending input as customerId,customerNumber,CustomerName to the web service, if the record is available i am getting the response and i am displaying those records on page as a table. Now when i click a row i need to populate another table with all sale orders of that customer. From webservice datacontrol i have only customer object, I dont have Sales Order Object. For this i need master detail relation. In this case how to proceed. Thats why i am thinking to create a vO and EO object for sales orders table and i want to create view link for this sales order and customers. As i don't have customer VO and EO object to create view link.

WebService dataControls
