Overloaded ejb methods as web service

I implemented an ejb as a web service. The ejb has 4 overloaded methods. When I looked at the generated wsdl, only one signature was exposed as a web service. Is there a way to make all 4 overloaded methods available to the web service ?

Hi Sandy,
The WLS 6.1 docs clear states that method overloading is not supported with WebLogic
Web Services:
http://e-docs.bea.com/wls/docs61/webServices/develop.html#1034539
However, you might be able to simulate something similar by passing a org.w3c.dom.DocumentFragment
to the method. For example,
public org.w3c.dom.DocumentFragment overloadedMethod(org.w3c.dom.DocumentFragment
variableArgs)
This allows you to use the flexibility of XML to provide various input and output
parameters for the method. In the method's implementation, you determine which
arguments have been passed by parsing the variableArgs node. For quasi type safety,
you could use the xsi:type attribute to associate data types with fragment elements.
Note that you will need to use literal XML encoding to do this.

EJB 3.0 Web Service

Hi!
I tried to create a Web Service (through wizard) from existing EJB 3.0 Session Bean. Basicly, the wizard just added @WebService annotation to my existing code...
Now, the problem is that simple methods like:
@WebMethod
public String helloWorld() {
return "Hello World!";
}works fine. Expect that if I use Local Interface for this Session Bean, the WSDL shows two helloWorld methods (and one is with exclamation icon showing some kind of problem with multiple methods with same name - but it is not true, I have one and the other one is just interface).
But, when I want to expose my real business service methods like:
@WebMethod
public List<Employee> getEmployees() {
return (List<Employee>)q.getResultList();
}it doesn't work (the Web Service create wizard finishes ok but service doesn't work)! When I try "Test Web Service" (from Session Bean context-menu) or "Show WSDL for Web Service annotations" the error is thrown (Null pointer exception in WSDL).
Basically, it looks to me that Web Service cannot use EJB Entities as parameters or results. Is this correct? I saw some examples on EJB 3.0 web services and there are entities routinely used as both input and output parameters.
Can someone, please, explain me what I'm doing wrong here.
Thanks in advance,
Pedja
P.S. In Web Service wizard, only SOAP 1.1 is enabled. How can I choose SOAP 1.2? And what EJB 3.0 bindings are in same context (SOAP 1.2 or EJB 3.0 bindings?)?

Hi Frank,
Most of those problems are resolved (NPE was due to Timestamp field, and two methods with the same name in WSDL because of not choosing to generate SEI in wizard, so the generated WSDL had one method from the Session bean and the other from it's Local interface). But, the errors should DEFINITELY be more descriptive.
Does the wizard work correctly? I noticed plenty of "bug like" details. For example, if I choose to create asynchronous web service, later when I go to Properties the "Asynchronous Web Service" checkbox isn't checked. Also, the @WebMethod annotations are sometimes generated and sometimes not (even if the method is checked to be exposed).
I am also getting these exceptions when I create a proxy for the asynchronous web service (I selected "Generate asynchronous methods for all operations"), could be I'm doing something wrong:
WARNING: The parameter/return type "java.util.concurrent.Future" in the method
"public abstract java.util.concurrent.Future<?>
view.proxy.MyAsyncWebService1.queryDepartmentFindAllAsync(javax.xml.ws.AsyncHandler<view.proxy.types.QueryDepartmentFindAllResponse>)"

EJB exposed as web services

I am very new to web services.
I understand that a Stateless bean can be exposed using RPC style web services.
But I want to know if a stateless session bean can be accessed by EJB client and Web service client (java or non-java) simultaneously. ?
i.e. 1. Can same bean serve two types of client simultaneously.(java and non-java client)
2. Does this web service accept complex java object as input parameters. and how?

Hi Patrik,
> Exception raised from invocation of public void com.sap.sia.serviceMonitor.ServiceMonitorBean.initPostConstruct() method on bean instance com.sap.sia.serviceMonitor.ServiceMonitorBean@5a8ab489 ... ; nested exception is: java.lang.NullPointerException
The NPE occurs in the bean code, in the initPostConstruct() method or some other method it calls. Unfortunately, its stack trace is not available above, but you should be able to find it in the defaultTrace file.

Expose AM methods as web services

Hi All,
As searched results from the forum, most of posts talking about how to consume WS by generating java file from wsdl. My question is, can we expose an AM method as web services? If answer is yes, may I have some high level steps for following up?
If we expose AM method as an web service, does that mean we have to pack all FND/OA classes in war file then deploy it into OC4J container?
We are using an old AS and even don't have standalone OC4J server installed. Even I can install a standalone OC4J but I still don't know how to resolve above question.
Thanks & Regards,
KJ

I have used Glue (http://www.themindelectric.com/products/glue/glue.html) to expose some of our stuff as Web Services. I recently found this on serverside. It's pretty good.
http://www.theserverside.com/resources/article.jsp?l=Systinet-web-services-part-1
I believe that the middleware they use can be plugged into IPlanet. There is also an article in the knowledge base on the IPlanet site.

Expose a class method as web service

hi ABAPers,
is it possibile to expose a class method as web service? I would like to write a base class with common code, while derived classes implement specific application logic.
I have both R/3 6.40 and Netweaver 7.0 kernels, so I'm interested in both.
thank you.

No, it is not yet possible.
You can only create a web service for an RFC Function Module, Function Group or Business Object.
You may create a RFC FM as a wrapper to your Class methods and create a web service on the RFC FM.

How to overload method in web services ?

hi all !
how can i overload a web services method ? , i hear about using javax.xml.ws.RequestWrapper , but when i try to use wsimport , it say : error dupplicate method.
this is the sample from forum :
package my.ws;
import javax.jws.WebMethod;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
@WebService
//(name="HelloWS", serviceName="HelloWSService")
public class Hello {
      * Web service operation
     @WebMethod
     @RequestWrapper(className = "com.veera.Clac.CalculatorRequest", targetNamespace = "http://Calc.veera.com/")
     @ResponseWrapper(className = "com.veera.Clac.CalculatorResponse", targetNamespace = "http://Calc.veera.com/")
     public int add(@WebParam(name = "a")
     int a, @WebParam(name = "b")
     int b) {
          // TODO implement operation
          return 0;
      * Web service operation
     @WebMethod
     @RequestWrapper(className = "com.veera.Clac.CalculatorOverloadRequest", targetNamespace = "http://CalcOverLoad.veera.com/")
     @ResponseWrapper(className = "com.veera.Clac.CalculatorOverloadResponse", targetNamespace = "http://CalcOverLoad.veera.com/")
     public String add(@WebParam(name = "v")
     String v) {
          // TODO implement operation
          return "Veera";
}thanks

Hi, Eric,
Thank you for your quick reply.
The web service I am trying to develop is basically a generic Data Access Component to bridge between SQL server and a desktop .Net application. The application will have about 3000 users from WAN, therefore we want to have a server side component to handle connection pooling etc. Because of limitation of current servers, we are asked to develop a Java Web Service, instead of MS WS.
To make the component more reusable, I am thinking to have methods like this in the service:
RunQueryReturnRS(String Sql, WebRowSet, rs)
RunQueryReturnInt(String Sql, int NumRecdImpacted)
RunStoredProcedureReturnRS(â¦.)
RunStoredProcedureReturnInt(â¦.)
â¦â¦
You see, I would like to get whole resultset back to client, including both metadata and data in a format of generic resultset. When I paged through the Sunâs document, finding WebRowSet is claimed to be seariable, and ready for Web Service. I thought if I can use WebRowSet that will save me time to write new classes to hold resultset info and pass back to client.
Could you please tell me if it is a feasible approach?
Thank you.

EJB 3.0 Web Services - Custom Request/Response Wrappers

Hi All,
I'm having an issue using Document Literal Wrapped web services with EJB 3.0. I have declared a service endpoint interface(SEI) in one jar file, along with custom wrapper classes for the requests and responses. The wrappers have the XML content customized a bit (different type names, etc.), but should be compatible with the @RequestWrapper and @ResponseWrapper annotations. The implementation is in an EJB jar file that includes the jar with the SEI in it. My issue is that the wrapper classes I declared are not being used, and instead new ones are being generated. Is it even possible for it to use supplied wrappers, or does it have to generate its own (and if so, is it in any way possible to specify the XML types it generates). I've tested this with wsgen, and I get the same result (new wrapper classes, the ones I supplied ignored) as when I deploy it. Here is the output from wsgen:
Note: ap round: 1
[ProcessedMethods Interface: com.company.IngestorService]
[should process method: ingestProductDirectory hasWebMethods: false ]
[endpointReferencesInterface: true]
[declaring class has WebSevice: true]
[returning: true]
[WrapperGen - method: ingestProductDirectory(java.lang.String,java.lang.String)]
[method.getDeclaringType(): com.company.IngestorService]
[requestWrapper: com.company.IngestProductDirectoryRequest]
[should process method: datatypes hasWebMethods: false ]
[endpointReferencesInterface: true]
[declaring class has WebSevice: true]
[returning: true]
[WrapperGen - method: datatypes()]
[method.getDeclaringType(): com.company.IngestorService]
[requestWrapper: com.company.DatatypesRequest]
com\company\DatatypesRequest.java
com\company\DatatypesResponse.java
com\company\IngestProductDirectoryRequest.java
com\company\IngestProductDirectoryResponse.java
Note: ap round: 2
I note that is says "hasWebMethods: false". Could that be an issue? Could it not be seeing my methods as web methods. The SEI and the implementation class are in different jar files and different packages. Could this be an issue?
Here is the web service interface:
@WebService(
name = "IngestorService",
targetNamespace = "http://company.com/"
@SOAPBinding(
style = SOAPBinding.Style.DOCUMENT,
parameterStyle = SOAPBinding.ParameterStyle.WRAPPED
public interface IngestorService
@WebMethod(
action = "http://company.com/ingestProductDirectory"
@WebResult(
name = "response",
targetNamespace = ""
@RequestWrapper(
className = "com.company.IngestProductDirectoryRequest"
@ResponseWrapper(
className = "com.company.IngestProductDirectoryResponse"
public void ingestProductDirectory(
@WebParam(
name = "sourceDirectory",
targetNamespace = ""
String sourceDirectory,
@WebParam(
name = "datatype",
targetNamespace = ""
String datatype);
@WebMethod(
operationName = "datatypes",
action = "http://company.com/datatypes"
@WebResult(
name = "datatypes",
targetNamespace = ""
@RequestWrapper(
localName = "DatatypesRequest",
className = "com.company.DatatypesRequest"
@ResponseWrapper(
localName = "DatatypesResponse",
className = "com.company.DatatypesResponse"
public List datatypes();
Here are the datatype request and response wrappers:
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(
name = "DatatypesRequest"
public class DatatypesRequest
DatatypesResponse.java:
@XmlAccessorType(XmlAccessType.PROPERTY)
@XmlType(
name = "DatatypesResponse",
propOrder =
"datatypes"
public class DatatypesResponse
private List<String> _datatypes;
@XmlElementWrapper(
name = "datatypes",
required = true,
nillable = false
@XmlElement(
name = "datatype",
required = false
public List<String> getDatatypes() {
if (_datatypes == null) {
_datatypes = new ArrayList<String>();
return _datatypes;
Any help would be greatly appreciated. Thanks.

I have been trying to do the same... and it seems to be impossible... (or completly undocumented).
It seems that OC4J 10.3.x is ... no exactly fully EJB3/J2EE5 compliant...
Or something like that:
http://blogs.infosupport.com/berte/archive/2005/09/09/1117.aspx
IMHO... OC4J 10.3.x is still a preview for OC4J 11...
OC4J 10.3.x is kind of a J2EE4/5 hybrid... if you start digging in the documentation, you will find out that the only
way to have WS-Security is going back to J2EE4 http://www.oracle.com/technology/products/jdev/howtos/1013/wssecure/10gwssecurity_howto.html
(of course, I hope you probe me wrong)

Error during JNDI lookup Accessing Remote EJB (access to web service restricted using declarative security model)

Hello everyone,
I developed a Web Service prototype accessing remote EJB using the EJB
control with special syntax in the jndi-name attribute: @jws:ejb
home-jndi-name="t3://10.10.245.70:7131/AccountDelegatorEJB"

It would be best if this issue is handled as an Eval Support case. Please

Andre,
It seems you are using the URL
jndi:t3://secuser1:[email protected]:7131/AccountDelegatorEJB
whereas you should not be specifying the "t3:" protocol.
The URL should be like
jndi://secuser1:[email protected]:7131/AccountDelegatorEJB
Please do let me know if you see any issues with this.
Note that this will only allow you to access remote EJBs in the same WLS
domain. For accessing EJBs on another domain, you need to configure
inter-domain communication by
following a few simple steps as mentioned at
http://e-docs.bea.com/wls/docs81/ConsoleHelp/jta.html#1106135. This link has
been provided in the EJB Control Workshop documentation.

Can you try using the following url with username and password
jndi://username:password@host:7001/my.resource.jndi.object ?
once you add webapp level security, the authenticated is the user who
invokes the EJB.
http://e-docs.bea.com/workshop/docs81/doc/en/workshop/guide/controls/ejb/con

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.

JCO in a EJB used as Web Service

Hi All,
I'm trying to use JCO in a Web Service. What happens is that as soon as I try to call -any- JCO method I get an error: Exception in method getObjects.I can't even seem to catch this error within Java for a personalized message. I can't find an error in "dev_jrfc.trc" either.
To use JCO I referenced sapjco.jar as an external JAR in the Libraries from the Java Build Path.
Calling the JCO in a Web Dynpro environment doesn't give problems.
Does anyone know the reason for this and can help?
Thanks,
Jeschael

"JCO function" changed in "JCO method"

Hi, Jeschael!
I suppose you already tried out calling R/3 FM via JCo in a simple test class, which - without any surrounding - just executes the JCo-call and outputs the returned values or any exception.
What was the result of this? The above mentioned exceptions while creating the client? For debugging the Web Service, you simply have to set a breakpoint in your EJBs method and start via NWDS a remote debugging session. As soon as the Web Service call is executed, the NWDS should open and execution should stop at breakpoint.
Another thing is: Did you already consider using Enterprise Connector for accessing R/3 functions? It' s much more comfortable enabling type-secure and stable usage of R/3 FMs.

How can i solve it??

Can you try and see if installing JDeveloper into a directory with no spaces in it (i.e not in \JDeveloper Workspace\) solves the problem?

EJB 3.0 Web service fail to deploy when ws result is on a diff lib project

I'm trying to develop a web service using EJB 3.0 with annotations. I'm using Netbeans 5.5 EE.
The web service should returns an object declared on another Netbeans project.
( a library.jar).
Netbeans compiles everything alright, although when I deploy the application into Glassfish it complains with an error saying that wsdl file for the web service wasn't found.
If I move the returning object class into the same ejb project as the web service it works fine.
So, can anybody explain what is happening ? Is it a bug of Netbeans, Glassfish, EJB 3.0, JAX-WS or newbie programmer ?

Unable to expose a method in web service

Hi,
My scenario is to expose a method in service. This method will take date as input & should return all the rows.
To Implement this, I took employeeVO of HR DB(Employees Table) & created a ViewCriteria "GetEmpbyHireDate" with Hiredate as input param.
& in AMImpl the code is
public BaseEmployeeVOImpl getEmployeesByHireDate(Date hiredate){
BaseEmployeeVOImpl baseEmployeeVO = (BaseEmployeeVOImpl) findViewObject("BaseEmployee1");
baseEmployeeVO.setApplyViewCriteriaName("GetEmpbyHireDate");
baseEmployeeVO.setNamedWhereClauseParam("pHireDate", hiredate);
baseEmployeeVO.executeQuery();
return baseEmployeeVO;
The issue is I'm not able to see this method in "Available" list of Web Service Wizard.
Help me in understanding what is missing ?
Thanks in advance.
P.S. from Jdev Help I understood that "Only methods with simple attributes as parameters and return types that are either void or view rows will appear in the list." & my method is returning rows of a EmployeeVO.

Hi,
2 comments:
1) View Criteria can be directly exposed as find methods. Its on the last wizard page (just click the View Criteria tab). So no need for an Impl method
2) If you wanted to expose a method, then the documentation I think is crystal clear: "oracle.jbo.server.ViewRowImpl or any subtype" Your method returns BaseEmployeeVOImpl (see the difference ?)
