Overloading Web Service Methods?

I am using WebLogic Workshop on the BEA WebLogic 8.1 platform. I would like to know if it is possible to overload web service methods from .jws files or any other means of implementing a web service. I tried a test file and it gave me specific errors related to overloading, but I have been unable to find any good documentation on the subject to be sure. Any information on the subject of overloading web service methods would be appreciated. Thanks.

Hello ,
It is very clear from following solution published by BEA that funtionality you are looking for is not supported. Do check this link to make sure if it refers to the same your scenario ...

How to add a new filter in an existing web service method (BIWS - WEBI document)

Hello Experts, we have 7 web service query's connected to a dashboard. Basically it is one WSDL URL and 7 Get Methods...Web service queries are BIWS (via WEBI document instance). There are filters setup for each of these web service methods.
Recently there was a request to add 2 new fields to the webi document and also the 2 fields need to be included as filters in the 7 methods. I know there is an option to edit the method, but when i edit the method, i cannot find the 2 new fields in list to set as filters.Can anybody help me understand how to add filters to an existiing web service method? I do not want to delete the method and republish the block as web service.
Any help will be great and points rewarded.
Thank you
Ann

Hi Ann,
The reason you are not able to see any of the new columns as a option to select in your web service block is because when you have published that block, they were not present. Add these two new objects in your block and publish it again. You will be prompted for duplication content. Select the highlighted block for duplicate and now you can see the new added objects in the filter option. Update and this will overwrite your published block. Please note, web services do appear to behave weirdly when used with dashboards so I request you to please try it in a separate test report first.
Hope that helps.

Tanisha

Calling Web Service Methods in Web Dynpro

1. Created a Bean with get & set methods..Created a portal Service around it
2. Created a Web Service and checked the same using EP Web Checker
3. Created a Web Dynpro app having two screens (First one for setting String value and second for getting string value)
4. Configured the Web Service in the model...I can see the Request and Response in the Context...Mapped the request to first view and Response to Second View
How do I call the Web Service method to Set the Paramter and how do I extract the value from the response?

How to retrieve the multiple rows data on PDF form in a web service method using WSDL DataConnection

How to retrieve the multiple rows data on PDF form in a web service method using WSDL DataConnection.
I have a multiple rows on PDF form. All rows have 4 textfields. I want to submit the multiple rows data to a method defiened in webservice.
Unable to retrieve the data in multiple rows within webservice method.

Hi Paul,
I'm now able to save the retrieved xml in a hidden text field and create dynamic table, and I'm able to fill this table from the XML, but the problem is that I could not find the correct way to loop on the xml, what I'm trying to say, the table will have number of rows with the data of the first row only, so can you tell me the right way to loop on the xml!
this is my code
TextField1.rawValue=xmlData.document.rawValue;
xfa.datasets.data.loadXML(TextField1.rawValue, true, false);
for(var i=0; i<count; i++)
xfa.form.resolveNode("form1.P1.Table1.Row1["+i+"].Num").rawValue = xfa.datasets.data.record.num.value;
xfa.form.resolveNode("form1.P1.Table1.Row1["+i+"].Name").rawValue = xfa.datasets.data.record.name.value;
Table1.Row1.instanceManager.addInstance(true);
Thanks

Web Service Method that returns an ArrayList

Hi guys,
I have to create a web service method that returns an ArrayList, but it's not working. My problem is:
With the "@XmlSeeAlso" annotation, my client prints the result, but the ArryaList is not from java.util, it's from org.me.calculator so I can't use it.
If I remove this annotation, I get no result, with this error message on Tomcat 6:
[javax.xml.bind.JAXBException: class java.util.ArrayList nor any of its super class is known to this context.]
I'm a newbie, and trying to understand web services (I read some posts here, but didn't get the point, from its answers), but this problem I just can't figure out how to solve....

I forgot to say that, when I try to return an ArrayList of an object, for example, ClassA, which is on the package org.me.classes, on my Server App, the ArrayList is returned, but the objects are from type org.me.calculator.ClassA. It should be from org.me.classes.ClassA, right?
This package also exists on my client App, to use the object, but as the returned type is from another package, I can't even cast it. I tried some annotations @Xml... but it failed.
Packages
ServerApp
org.me.calculator
CalcWS.java
org.me.classes
ClassA.java
Client App
org.me.classes
ClassA.java
The return from my method should be an ArrayList of org.me.classes.ClassA, but when I print it, on client, it's from org.me.calculator.ClassA.
Does anybody knows, or had the same problem?
Thanks,
Eduardo

Capturing the response received from the WCF web service method?

Hi,
I am trying to call a WCF web service method with input parameters in an xml file and then receive the returned output data by the web service as response into an xml file.
So far I am able to call the webservice method successfully and not sure how to capture the response data. I am able to see the response data in the tracked message event using the query expression search at the BizTalk group root.
I may be missing something simple in my orchestration(image at http://social.msdn.microsoft.com/Forums/getfile/535971) ?
Steps in my orchestration are,
1) Receive the xml file with input parameters
2) Send to webservice using WCF-BasicHttp transport type
3) Receive response from web service
4) Send to xml file
Not sure how I can have 2 receive shapes in series there. I have seen few related posts in the forum but could not resolve.
Could someone please correct me?

Hi Rachit,
Thanks for your quick response. My orchestration is similar to the one in that post. In your post at step 7, how you are able to set 'Activate property' of the receive shape to true? as its the 2nd receive shape in series.
I am unable to post any images or links at the moment. My orchestration is posted at this link http://social.msdn.microsoft.com/Forums/getfile/535971
I am able to access the above link using chrome.
Yes, I did use the Request/Response port to communicate with the web service. I
am looking to achieve similar to the one in your post.
Thanks.

How to test swaref web service method

My simple web service method:
     @WebMethod
     @XmlAttachmentRef
     public DataHandler getFile() {
          FileDataSource file = new FileDataSource("c:\\1.gif");
          DataHandler handler = new DataHandler(file);
          return handler;
the generated wsdl codes:
*<xs:complexType name="getFileResponse">*
*<xs:sequence>*
*<xs:element minOccurs="0" name="file" type="swaRef:swaRef" />*
*</xs:sequence>*
*</xs:complexType>*
I always use Eclipse web service explorer to test web service, but it doesn't support swaref web service method.
Then I use axis WSDL2JAVA to generate web service client, but the generated "getFile" return type is not "DataHandler", but "org.apache.axis.types.URI".

Hello..
How did u develop the webservice?
I mean did u develop the Webservice using Enter prise Java Bean....
Wrap EJB in ear and deploy to the Server and now u can test the EJB method
whether it is working fine or not
Try these -
http://help.sap.com/saphelp_nw04s/helpdata/de/f7/af60f2e04d0848888675a800623a81/frameset.htm
Inorder to use the webservice in the Webdynpro, normally we will use the WSDL of webservice
and Import the model using any one of them
After importing as model we can use the EJB methods!
Try it !!
Thanks

Web service Method not supported

Hy, i have this serious problem.
I have any web service method that in , Visual Composer 7.1, have the suffix "Not supported".
I don't understand this situation because i can test it on web service navigator with success.
This is the SOAP request/response from Web service navigator test:

Thank's Shay. I'm thinking that the problem is about NWDS for this reason: at the moment i am testing a standard web service present on WAS( http://serverWAS:53000/IciUserService/IciUserConf?wsdl)that with a method ( getAttributes) that return an array of classes on VC and this test is ok.
So i'm creating an similar web service that return array of classes with my NWDS (vers. 7.0.7..) and wizard but on VC it's don't supported.
The SOAP Response of standard web service and my web service, have different structure. I'm thinking that the problem is NWDS because the SOAP response is function of the WSDL generated by Wizard on NWDS.
Thank's in advance.

TimeoutException - when calling web services method that opens a PDF

I am updating a legacy program which uses Adobe Acrobat 7.0 Professional. The idea is that the client will call web service methods, which handle opening a PDF, reading from or writing to the PDF, saving if necessary, and closing. It then returns the data (if reading) to the client.
The only issue with this that I'm having is that the client will pause for about 60 seconds, and throw a TimeoutException.
I know that the method on the web services end is working, because I wrote a quick driver which calls the very same method, but it executes normally, and works perfectly.
My question is basically, is there anything that would cause the client to hang/freeze when calling the web services method to do this task? Everything is running on my workstation, and I've debugged to see that the filename being passed is the same in both tests.
Thanks!

Thank you, I somehow missed seeing that subforum. I reposted it in that forum instead. This thread can be deleted/closed. Thanks!

Serialization error when calling web service method

Hi,
In JDeveloper 10.1.3.1, I'm working on an EJB that will be deployed as a web service. There is a method in the EJB that is defined to return a generic Object, but in the implementation, it really returns one of several possible specialized bean objects. I can deploy the EJB successfully to IAS 10.1.3.1.
I created a web service proxy from the wsdl that was generated from deploying the EJB. Using the proxy, I try to call the EJB method and cast the method's return value to the bean object I know should be returned. However, I get an error like this:
java.rmi.ServerException:
start fault message:
Internal Server Error (serialization error: no serializer is registered for (class com.test.TestBean, null))
:end fault message
Does anyone know how this serialization error can be resolved? If I change the web service method signature to return the bean object that is actually being returned (instead of Object), then it works fine. But I want to be able to define the method to return a generic Object because I plan to make the method flexible enough to return several different types of bean objects. Whenever the client calls the method, it will know what is the actual object being returned and I had planned to cast the return value to its actual class.
Thanks for any ideas.

Well, I think so... I've followed all the steps, and my merged WSDL file seems like the one in page 12...
Any suggestion, please?
Thank you,

(261680070) Q SYNCH-11 How do my web service methods accees EJBs and java classes?

A<SYNCH-11> How do my web service methods accees EJBs and java classes?
A<SYNCH-11> It is simple to use java classes, just do it as you would ordinarily.
The .jws file really contains a simple class so you can program with it in the same
way that you would use a regular Java class.
To use an EJB you can go and access it directly as you would with any EJB remote
client (lookup home stub, create, etc) or if the EJB is deployed to WLS you can use
a control to provide a very simple wrapper to the EJB. We will see this in detail
on Thursday in the ADVC module.

Futher information about the possibility of callback:
It may be possible for a synchronous only web service (i.e. MS .net) to even paticipant
in the callback functionality of asynchronous web services. If the client implements
the appropriate methods for the callback but listens for them on a different port
or binding than the SOAP request, then web service may be able to build a response
if the client's "callback URL" is submitted as the beginning part of a conversation.
Watch the BEA developer forum (http://dev2dev.bea.com) for more information about
this approach and other tips and techniques for building web services.

Q<SYNCH-03> I heard that MS .net only implements synchrnonus method? If
this is true.
Does it means my async methods will only work with J2EE clients?
A<SYNCH-03> I do not know the limitations of .net but let me point out that
is very
difficult to provide asynchronous web service method invocation (this is
different
from an asynchronous web service). HTTP as a general communication protocol
is based
on a request and response paradigm so your client libraries will mostly
likely be
expecting a response even if it is empty (check the asynchronous example
from today
to see that the start method still returns an empty response). You must
distinguish
this from the notion of an asynchronous web service which is a business
operation
that occurs on the server whose return value/result is not directly associated
with
building response to the client. An asynchronous web service can (and generally
will)
be started and stopped with web service operations that are invoked synchronously.
Thus MS .net clients can still be client to WLS hosted web services.

Run Web Service Method when OC4J starts

Hi,
I have a number of web services running under OC4J.
Is there any way to execute a web service method on OC4J startup?
Thanks in Advance

Hi,
My services act as services within oc4j.
There are essentially multiple deployments of the same .ear, with the application name being used to discern between the service instances.
I know that I could create proxy classes and then use an OC4JStartup class to fire a method at startup....
However, this would mean that I would need to create a proxy for each instance ....
Ideally I would like to have some sort of configuration file that holds the url to each instance --- then use the url within the OC4JStart class to fire a method on each URL
Thanks

Calling Oracle Report InSide Web Service Method

Is there way to call oracle reports inside one of my web service method.
If yes kindly let me know how we can do this and some documents related to this.
Thanks
Robert

Oracle reports does have a Web API when reports are run from the application server. As a result one way to do what you are asking is to write a Web service that use java.net.URL to invoke the Reports Service Web interface:
http://otn.oracle.com/products/reports/htdocs/getstart/docs/A92102_01/pbr_run.htm#1005598
As I understand it, this interface itself is actually being exposed as a Web service in a future release of Oracle9iAS Reports ... I don't know if this is a Oracle9iAS Reports 9.0.4 feature or beyond that. You might try asking on the Reports forum:

Type mismatch on SOAP Web Service method invocation

When I run the generated client for a web service, I get the following error, which I can get rid of by using a primitive type (e.g. String) as the parameter to doSomething instead of wstest.test2.APIClass3, i.e. the SOAP server seems happy handling wstest.test2.APIClass1 as a return type, but not a similar class as a parameter type:
[SOAPException: faultCode=SOAP-ENV:Server; msg=type mismatch [java.lang.IllegalArgumentException]]
     wstest.test2.APIClass1 wstest.test2.EmbeddedStatelessTest2Stub.doSomething(wstest.test2.APIClass3)
          EmbeddedStatelessTest2Stub.java:89
     void wstest.test2.EmbeddedStatelessTest2Stub.main(java.lang.String[])
          EmbeddedStatelessTest2Stub.java:48
I am using JDeveloper9i 9.0.3 Preview and the standalone OC4J 9.0.3 that came with it. I followed the Oracle9i JDeveloper 9.0.3 Web Services Quickstart Install (http://otn.oracle.com/tech/webservices/htdocs/quickstart/quickstart903.html) to get OC4J running standalone. I had to register the stateless EJB provider, and the WEB services wizard didn't manage to include APIClass2 (an instance of which is contained in APIClass1) in the .dd so I added it manually which works fine with APIClass1 as the method return type.
Sorry for the length of this posting, but I wasn't sure which bits would be relevant.

EmbeddedStatelessTest2Stub.java
===============================
I change the http port from 8988 to 8888 to get this working. Also, the generated referenced a new class APIClass31, also generated, but as it didn't make any difference to the problem I replaced it with APIClass3, which has essentially the same characteristics.

I believe this is a bug in JDev/OC4J 9.0.3 that is being further investigated right now. I have duplicated your problem in a simpler test case and folks are looking into it.
