Custom method in application service

Hi All,
i have created a custom method in an application service.But It is not being shown in service browser.
Can you plz tell me what is the reason?.
Thanks
Sampath.G

Hi Sampath,
I think you haven't checkied the thread I mentioned carefully. As I mentioned in my previous reply the CAF Service Browser is based on CAF Web Dynpro model which has lot of limitations. You can refer the <a href="https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_caf/~form/handler">SAP Note 1030595</a> and <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/20063659-4f03-2a10-6a8a-d88786c39b71">this document</a>. After refering these documents you'll understand that CAF Service browser don't support all types of custom application service operations. To test the application service create web service out of it and test it from wsnavigator.
Thanks,
Dipankar

Invoking custom methods in application modules

Hi,
I am absolutely new to oracle ADF.I was recently working with application module.My question is how do I call a custom method(say myCustomMeth(String str) ) residing inside my application module from my Managed bean?I saw one example where the operation(i.e. the method) was directly dragged and dropped onto the jspx page from the data control.Is it the right way of doing it?I also saw one example where operation binding was used to invoke a method inside the application module although I didn't understand the code fully.I am really confused now.Please help.
Thanks in advance.

My question is how do I call a custom method(say myCustomMeth(String str) ) residing inside my application module from my Managed bean?You write the custom Application Module method and you expose it to the AM's client interface. By doing so, the custom operation becomes available in the AM Data Control and can be bound to your jspx page.
I saw one example where the operation(i.e. the method) was directly dragged and dropped onto the jspx page from the data control.Is it the right way of doing it?I also saw one example where operation binding was used to invoke a method inside the application module although I didn't understand the code fully.Both of the methods that you are mentioning above are used:
1. You can drag the custom method from the data control in JDeveloper and drop it in your page as a command button or link to create a method binding declaratively this way. The method binding is executed via some command button or link and your custom AM method is called, or
2. You can create the method binding yourself in the bindings tab of you jspx page, add the command button in your page and define an action listener for it in your backing bean. In your backing bean action listener you can write the necessary code to execute the method binding, which will call your custom AM method.
Hope it is clear.

Adding and Calling custom method to the application module or view object

My project uses jheadstart 10.1.2.
I want to run "oracle reports" from my uix page. I have coded a method which takes "VOParameter view object" as a parameter to run report.
I have generated the input page (parameter page) which based on VOParameter view object, by using jheadstart for using jheadstart lov, date etc. advantages. But I dont know how can I add custom method on application module or view object implementation class and custom button on uix page to call from uix page.
THANKS for your help

Yes, method binding has been added to the page UI model.
I have find some clue that When I darg and drop metod as a submitButton, the code "
<SubmitButton text="runReport" model="${bindings.runReport}" id="runReport0" event="action" />"
is added to the uix page code. I change this code like this;
<button text="runReport" model="${bindings.runReport}" id="runReport0" event="action" onClick="submitForm('dataForm',1,{'event':'action','source':'runReport0'});return false"/>
by adding onClick method and changed submitButton to button tag..
Then button action is triggered. But I can not pass to the design part of the uix page. It gives me the message like that "The document is not a valid state" But it works. I dont know why?

Method signature of Application Service is changed by Webdynpro

Hi,
I have created a method in application service which takes 3 string arguments. It access create() of Entity service. when I try to access the same method in webdynpro, I found the signature of method is changed.
Method   in Application service is <b>addNewRecord(String, String, String</b>). I found in webdynpro ..<b> addNewRecord(IAspect,String,String,String)</b>. why signature of method is changed? how to construct IAspect object?
Thanks in advance..

This is how you would execute such method
          IServiceFacade serviceFacade = CAFServiceFactory.getServiceFacade();
                         IServiceModule serviceModule = serviceFacade.getServiceModule(CorecafDefinition.APPSERVICE);
                         IAspect aspect = serviceModule.createAspect(CorecafDefinition.APPSERVICE);
          IAction action = aspect.createAction(bams1cafDefinition.APPSERVICE_METHOD);
          action.getInputParameterStructure().setAttributeValue("Var1", val1);
          action.getInputParameterStructure().setAttributeValue("var2", val2);
          action.getInputParameterStructure().setAttributeValue("var3", val3);
          action.execute();

How to catch the user defined exception in application service

Hi All,
How to catch the user defined exception in application service when it is throwed by the external service..
Regards,
Thirumurugan.

Hi,
    Thanks for your reply,
        Actually I am calling validate Login method of External service from the application service. When the login fails, my external service will throw user defined Exception.I want to catch the user defined Exception.
    But in the application service , validate Login method can catch only Invocation Exception and Engine Exception.
   These two exception are present in the Application service remote interface.
public com.sap.comptest.extsrv.accrjavawsvi__document.output.
Ns1_validateLoginResponse validateLogin(com.sap.comptest.extsrv.accrjavawsvi__document.input.Ns1_validateLogin input) throws com.sap.caf.mp.base.exception.InvocationException, com.sap.caf.mp.base.exception.EngineException;
User defined exception is not present there. When i include the webservice as external service in CAF, it suppossed to generate the java file for the custom exception of validate Login method and this generated file should be included in the application service remote interface..
public com.sap.comptest.extsrv.accrjavawsvi__document.output.
Ns1_validateLoginResponse validateLogin(com.sap.comptest.extsrv.accrjavawsvi__document.input.Ns1_validateLogin input) throws com.sap.caf.mp.base.exception.InvocationException, com.sap.caf.mp.base.exception.EngineException,
(generated file name of user defined Excpetion.
Then only validate login method of application service can catch the user defined Exception which is thrown by the external service.

Call external service in a Application service created from ES

Hi Experts
I have the follow situation:
I've modeled a new service in Enterprise Service Builder. This service i'll implement in caf application. In the method create by application i'll call one method of external service.
I imported this modeled service in Create Web Service Provider option in external package, select the Enterprise Service Repository source option and choice the respective Service Interface.
In this moment the caf created a new application service, with methods of modeled service. That's all right.
Now i import a external service of esworkplace. All the step are ok. But the problem is going to next step.
I need to call this imported service in the method of application service. I know 3 way to do this:
1. Mapping the external service with this application service. In this case i have a problem - the method of external service is expose as web service, and i don't want this. Just the method of modeled service must be expose.
2. Create another application service, map the external service with this application service, and create a depency between this application service and the application service created by modeled service. I think this work fine and resolve the problem of expose the method of external service. However i think this isn't a good way to do.
3. Instantiate the service class of exernal service. From this class i can call the method of external service in application service. But now i have another problem. If i see the implementation of this class, it have a static block which call a URL class, and pass as parameter a wsdl file located in one directory of my computer like
url = new java.net.URL("file:/D:/SAP7110Workspace.jdi/LocalDevelopment/CRVP/demo.sap.com//ejbmodule/
_comp/tmp/0/EJB/src/META-INF/xml/ext/rootwsdl_WorkCentreSimpleByPlantQueryResponse_InService.wsdl");
when execute the application in the server it don't find this file and i give one error.
I think the best way to do is the 3° way. But why did the caf generate the URL with My computer directory instead of in directory of application? There are some solution to this problem?
I've change this line manualy, but all the time when i generate the project, i need change this code again.
Regards
Marcos

Hi,
You may consume external service via JNDI
Context context = new InitialContext();
<JNDI OBJECT> local = (<CAST JNDI OBJECT>)context.lookup("<JNDI OBJECT>");
//Call the method
If you are using CE 7.11, go to NWA -> Problem Management -> JNDI browser > ..... -> ObjectName for <JNDI OBJECT>

Two different ways to execute a custom method in an Application Module

I have a custom method exposed in an Application Module's Client Interface, and i know two different ways of executing it from my ADF Faces project (both works fine):
1) Calls the method directly through the Data Control:
MyModule service = (MyModule)JSFUtils.resolveExpression("#{data.MyModuleDataControl.dataProvider}");
service.myMethod();
2) Adding a Method Action in the PageDef's file:
<methodAction id="myMethod" InstanceName="MyModuleDataControl.dataProvider"
DataControl="MyModuleDataControl" MethodName="myMethod"
RequiresUpdateModel="true" Action="999"
IsViewObjectMethod="false"/>
//Call the method from the binding container
BindingContainer bindings = getBindings();
OperationBinding operationBinding = bindings.getOperationBinding("myMethod");
operationBinding.execute();
Basically i want to know: what are the differences (pros & cons) of each approach ??

Hi,
In my opinion the second way have a advantage, which its method could be invoke automatically using a invokeAction on pageDef, if necessary.

Step by Step to access custom Java API in Application Service.

Hi Experts,
I have a situation to access the custom Java API in CAF. The Java API fetches the data from MDM. I need to get the data from that API and and use it in the CAF Application Service layer? Is there a way to access the JAVA API in the Application Service Layer? If so please do help me out. Step by Step solution would be appreciated.
thanks in advance.
Regards
Ketan

Hi Ketan,
You can do it in two ways.
1. You can create your own custom class in the ejbmodule which you can see in the Navigator view.
2. You can have a ear having the custom class. This ear will be in a separate DC and CAF will have dependency to it.

Complex data type to application service create method(CRUD)(Urgent)

Hi Experts,
I have created an entity service with remote persistency(Web service).i am mapping the entity service CRUD methodes to web service methodes and i am calling these CRUD methodes form the corresponding applicaion service CRUD methodes.With out complex data types both sevices are working fine.I have tested them in the service browser.
Later I have created a complex data type in the entity service and mapped it to web service.But when i am creating the application service create(CRUD) method for this entity service the complex data type which i have created in the entity service is not being shown as possible input attributes of the application service create method.Due to this i am not able to pass this complex attribute form the application service create method to the entity service create method.
Plz tell me how can i resilve this issue.(Urgent)

Exception while exposing Application Module Methods as Web Service

Hello Everyone,
I am working on Jdeveloper 11.1.1.3.0 version and tried to expose one method of application module as web service. To do this, i used "Service Interface" tab of Application module within Jdeveloper and Jdeveloper had generated all interfaces, stubs, code for the Session bean required for web service. I am now trying to "Test Web Service" from the implementation class generated then i am getting this error in Weblogic deployment. Any help/pointers would be highly appreciated.
I used another installation of Jdeveloper same version at my collegues desktop but getting the same error. Not sure, if this version of Jdeveloper is having issue in exposing application module as web service. I think that database related exception can be ignored as no database call is being made by the application.

Method as a WEB Service in an Application Service

Dear Colleaguaes,
When importing a web service method into a caf project, and exposing it as method into an application service, is it necessary to create an Entity Service as Web Service wrapper still?
I can check that a web service method works, it returns the data, but it returns nothing when I try to test the corresponding method in the application service.
I've also created a destination in Destination Template Management and done the external service to the destination configured mapping. But still without success....
Thank you in advance,

Hi,
Thanks a lot for your help.
Sorry i didn't specify before but I also have created Web Service Proxy from the URL of my Web Service into my web app. But now I don't now how to use the method that i created on my web service on to my web application.
To be more specific I don't know how to wire the two af:InputText with my web service method in the way when I click the submit button it past the info to web service and which has to return the Student ID :
Ex:
Name: af:InputText
LastName: af:InputText

How can I call the create method in BO from Application Service

Hello!
When I create a Business Object, CAF generates some methods automatically.
How can I call the create method in the BO from Application Service logic?
When i call the method then the entityManager and the sessionContext is NULL.
How can I initialize this?
Can anybody help me?
Thanks, Thomas

If you are using CE 7.11...
1) In the Application Services, add the BO as dependant object in dependencies tab.
2) In the implemention, add the following codes to call create method of the BO:
this.get<BO>.createMethod();

Problem in Viewing Application service methods through Service Browser.

Hi All,
I have an Application Service (ReadFundDetails) which contains some Operations
1> createFundAtSA
2> updateFundAtSA
But I cant see the operations under the Application Service through service browser.
I have deployed the project in two diff server. But the same problem persists in both the server. All the class files under the jar file have been generated successfully. There is no build issue. I have undeployed the project then build and redeploy but still the problem comes.
I have another project for which i can see the Application Service operations successfully.

Hi Mithu,
CAF service browser is based on CAF Web Dynpro model which has several limilations. Check the SAP note <a href="https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes/sdn_oss_caf/~form/handler">1030595</a> and <a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/20063659-4f03-2a10-6a8a-d88786c39b71">this</a> document for more details on the limitations of CAF Web Dynpro model. To check the operations working properly create a web service for the app service test from the wsnavigator.
