I developed a webservice, that need to be return a ICollection object.
while am doing this it showing an error that.

can u help me in this context
my code is like

return iCollectionObj;
above code dirObj.GetResouceTypes() method return a collection that i explicitly converting to ICollection object and retuning....

Is your patching is still in progrees?If you are patching for basis components then you can expect dumps and they will not allow you to login to the system sometimes .In this case we can perform import from os level to get rid of the issue.
If your patching is in progress then I would prefer you to wait till it completes.And if this is happening after patching I request you to post log file entries.

Problem with web service that returns an object with a String that have som

Hi everybody:
I have a problem with a web service I am doing, I have made a web service that returns a collection of objects, the objects have a set of properties, there is one property that is a String,this property consists in a text fragment that could have some characters that are considered special in XML like &, <, >, " and that's why when I execute the service from a client an exception is thrown:
{code}
Exception in thread "main" org.codehaus.xfire.XFireRuntimeException: Could not invoke service.. Nested exception is org.codehaus.xfire.fault.XFireFault: Could not read XML stream.. Nested exception is com.ctc.wstx.exc.WstxParsingException: Expected a text token, got START_ELEMENT.

I know that this is happening because special characters are sent by the soap message but I don't know how to solve this problem.
How could I avoid this exception ?
I hope you can help me.

Hi,
BPEL and BPEL PM do not have a good support for SOAPENC-Array: it would be very difficult to create such an array in BPEL or to receive it and manipulate it.
The (unfortunately very intrusive) work around is to change the WSDL of the service to use a XML type defined using XML schema. This is all the more painful that JDev 9.0.4 does not have strong support for complex types.
In general though, I would highly recommend this best practice:
1) Start by define the WSDL contract first
2) Then generate the server side skeleton to implement it
3) Use BPEL as the client to this contract.
By starting with the contract first, you make sure that 1) your interfaces are clean and coarse grained.
2) things like java objects, sessions, etc to not leak through the interface (which would be the worst thing that could happen because it would closely link the client and the server.
Sorry for not being more helpful. This will get radically cleaner in Oracle AS 10.1.3.

Web Service not returning Boolean objects from DTO class

Hi,
I've seen posts reporting the same problem on other forums from a few years ago that are unresolved.
I've created a service in NDS that has a method that returns some data via a DTO class. All the data is returned apart from those that are of type java.lang.Boolean. I thought the method names might be causing the problem so created a "get" method as well as an "is" method but it is still being ignored.
I have tested this using the Portal Web Service Navigator and by using the service in Visual Composer 7.
Is there a problem with Boolean data types in SAP Web Services ?
Thanks
Gary

Hi Rich,
No. In fact what happens is that in the se80 case, it returns 29 lines of results and in the wsadmin case it returns 25 lines of results. The web service/function module actually executes unit tests remotely by doing an RFC from the development system to the test system (where the unit tests are executed). In the se80 case, for one object, the unit tests execute correctly. In the wsadmin, the unit tests for that object don't execute hence returning less lines of result.
In both cases, the users used to log in the web service or se80 are the same and the users for the RFC are the same.
Thank you for your insight.

Philon

Problem in web service while applying patches

But there are still errors in spam.
Currently none of my webservice are working "Service Cannot Be Accessed !" .
Kindly provide me the solution.

Hi,
since I did not find that BAPI in my system: what is the exact name?
Did you test the BAPI directly in ABAP, i.e. function builder SE37, successfully?
Currently it looks to me as if you did not provide sufficient business data.
Did you specify the employee number before executing the call?

Problems with Web Services in Visual Studio

(Cross-posted from WAS forums)
I'm using VB.NET to access SAP BAPI's via web services from a 4.7 system. This works really well (and in my view is simpler than the .Net connector) until I try and add a Web reference to a SAP web service that returns a BAPIRET2 structure - as soon as I add the reference, I get a load of "Reference to a non-shared member requires an object reference" errors - one for each line in the BAPIRET2 definition that VS automatically adds.
Specific Example (guess who's been using OSS too long!):
1. Browse the R/3 Web Service Repository at:
http://yourmachinename:8000/sap/bc/bsp/sap/WebServiceBrowser/search.html
2. Search for BAPI_USER_GET_DETAIL, click the small "wsdl" link.
3. Copy the resulting URL, in VS add a web reference and type the necessary security details
4. Immediately in the task list 15 build errors show - one for each line of the BAPIRET2 definition.
Would be very grateful for any help on this!
Thanks

Did you ever get this figured out? I am having exactly the same problem in code generated by VS, with the BAPIRET2 structure.
Any help you could provide would be greatly appreciated.

Invoking a web service that returns binary

Hi,
Is it possible to invoke a web service that returns a binary object?
Its similar the following example but I need to return a binary object :
declare
v_url:='http://www.somesite.com/function_name?invoke=placeOrder&par1=val1'
v_output varchar2(4000);
begin
select utl_http.request(v_url)
into v_output from dual;
end;
Thanks in advance

No "advantage" as there are two very different tools.
UTL_HTTP is basically an Oracle PL/SQL web browser. It uses the HTTP application protocol. It is just like your ordinary browser (IE, Firefox, Opera), but as it is server-side and display-less, it comes without a rendering engine.
UTL_DBWS is to interact with web services using the SOAP application protocol.

BPEL build error when invoke an extrenal Web Service that returns an Array

Hello,
I built with JDeveloper a web service that returns an Array of Java Bean classes and I try to invoke this web service from a BPEL process. The wsdl file is automatically generated by the JDev. When I built the BPEl project I obtained the following error:
[bpelc] [Error] :-1:-1: src-resolve.4.2: Error resolving component 'SOAP-ENC:Array'. It was detected that 'SOAP-ENC:Array' is in namespace 'http://schemas.xmlsoap.org/soap/encoding/', but components from this namespace are not referenceable from schema document 'http://malangiu-ro:8988/cde-Project-context-root/CdeFactoryWS?WSDL'. If this is the incorrect namespace, perhaps the prefix of 'SOAP-ENC:Array' needs to be changed. If this is the correct namespace, then an appropriate 'import' tag should be added to 'http://malangiu-ro:8988/cde-Project-context-root/CdeFactoryWS?WSDL'.

Problem call Web Service SAML on PI 7.0

Hi experts,
I have a problem very estrange on one scenario and maybe somebody could help me:
Our PI version is 7.0.
The BPM has got the following steps:
- Call WebService for get the SAML. Message Synchronous with request and response Authentification.
- We add the Authentification Response on Envelope message.
- Call web Service with Envelope, inside of this one there is the Authentification (step 1).
The las Web Service always returns that the Authentification is error.
We execute the same steps manually using SAOPGui program ( a free program for test WebService ) and the same steps works.. and the structures are the same, but on PI 7.0 never works.
We researh on forums and we have seen that the SAML Authentification is soported only for PI 7.1.
Could anybody confirm it? It is possible use SAML Authentification on PI 7.0? Are there other process to execute a SAML WebService using PI 7.0?
Any response or any idea will be very appreciated.
Thank you very much...
Regards,
Gemma

It is possible use SAML Authentification on PI 7.0?
at least the help section on 7.0 mentions the use of SAML...check this link

Invoking a AXIS Web Service with a Java object as input argument

Hi
I've been trying to execute a bpel process that invokes a web service deployed through axis.
This web service takes a java object as input argument as opposed to data types that are directly mapped to java types through the SOAP engine.
I deployed and tested the service outside of BPEL using a test client class. Everything works well.
When I try to configure the "Assign" and "Invoke" activities so that service can be invoked, I cannot see the data structure through the variable picker and I see the following message:
"The element {urn:ComplexTypeWebService}TimeSheetBean is not know to the schema container. Perhaps a schema file that uses it needs to include or import its definition.There mat also be an XML schema issue (non resolvable schema) which prevents {urn:ComplexTypeWebService}TimeSheetBean from being seen by the schema processor."
Is there any example that demonstrates how to invoke an axis web service in such scenario? What am I doing wrong?
Please, let me know.

The passing of Java objects in and out of a web service is NOT supported. variables must be xml documents defined by a XML schema. In my opinion, missing Java object and WSDL is not a good idea. -Edwin

SQL Server 2008 Reporting Project - Invoke/Consume Web Service and Return Dataset in C# Code-Behind

Hello,
I have a Visual Studio 2010 C# class with a method that invokes/consumes a web service and returns an XML dataset. I am traversing through the parent/child nodes and parsing out the data then inserting it into a SQL Server 2008 R2 table for a join within
another stored procedure.
Instead of using a 3rd party API to generate the PDF for this data, I am creating an SSRS report. The formatting will be easier and I can do a RenderFormat directly to PDF.
Can I expect to be able to transfer the code-behind method to this report and have it be able to work with the web service the same way? It is a SOAP-based web service returning parent nodes and two levels of nested child nodes.
I have also been researching the approach of calling the web service in the same stored procedure that is currently querying the physical tables (which is used to populate a gridview and PDF) but it looks like it may only be possible with a CLR stored procedure.
Is it possible to implement a CLR stored procedure within an SSRS report?
Hope this makes sense. Any help, suggestion or point in the right direction would be greatly appreciated.
Thanks,
Buster

Hi Buster,
SSRS supports web service data source, we can call the SOAP-based web service in SSRS report directly. Then, we can use custom code in SSRS to parse the XML data. However, we won’t be able to join another data in SQL Server database.
Reference:http://technet.microsoft.com/en-us/library/aa964129(v=sql.90).aspx#repservxmlds_topic3
We cannot implement a CLR stored procedure within an SSRS report directly. In order to execute the CLR store procedure in a SSRS report, we have to execute it as text using the following code:
Exec <stored procedure name>
Reference:
http://dotnetslackers.com/Community/blogs/bmains/archive/2009/01/15/executing-a-clr-stored-procedure-in-reporting-services.aspx
Hope this helps.

2) When we create the Web service from custom business object what the necessary steps(action : Create , Read , Update) require?
3) Sample Scenario :
My Custom Business Object
businessobject Custom_Integration {
element EP_VAL1 : LANGUAGEINDEPENDENT_MEDIUM_Text;
element EP_VAL2 : LANGUAGEINDEPENDENT_MEDIUM_Text;
element IP_RES : LANGUAGEINDEPENDENT_MEDIUM_Text;
I have created the Web Service using this custom business object.
3) How i can use this web service in external system? what are the prerequisite steps in external system to consume this service in it?
Please anyone have idea about this how to do this and how to achieve this using SDK and custom business object.
Many Thanks
Mithun

Hello Mithun,
Does this section in the documentation help you:
SAP Cloud Applications Studio Help -> Developers Desktop -> Web Services
The entry "Task -> Create a Web Service" describes how to create a Web Service on your own BO
The entry "Task -> Test a Web Service" helps you how you can use it in a foreign tool / application.

Can we create a Web Service from a Business Object??

Hello All,
Has anyone created a Web Service using a Business Object?
When I am trying to create a Web Service in TM box, I can see that couple of options like Business Objects, Process Agents are disabled and rest like Consumer Group, Service Provider are enabled. Any idea why this is happening. Is this related to some configuration setting.

please elaborate in which environment or case you are creating Web Service from Business Object.As per my understanding we generally create web service through Wizard.

Web service to return all employees

Hi I am new to PeopleSoft but have managed to get the OVM template up and running now in virtual box and have the web services working again CI_CI_PERSONAL_DATA. This returns data for a single employee. How would I go about creating a web service to return all employee data in one response so that we and sync firstname, lastname etc with an external system? Thanks

Thanks Hakan, I'm trying to create a web service for the find operation but each time the wsdl created starts with "wsdl:description"
<?xml version="1.0"?>
<wsdl:description name="CI_CI_PERSONAL_DATA.2" targetNamespace=
instead "wsdl:definitions" as with the original one I created for the get operation.
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:M477757.V1
SoapUI is not happy about the new wsdl format. Any ideas what I've done wrong?

How configure a primavera web service to return data from the second database?

Hi everyone,
We have P6 with first WS deployed on a single server weblogic domain. The first WS return data from the first database instance.
Then deployed advanced second WS on a separate weblogic domain server with a different port. Configured second WS with <WS2_INSTALL_HOME>/bin/dbconfig.sh, creating a new branch of a configuration that specifies a different second instance of the database. However, this configuration is ignored and second web services return data from the first database.
We have one domain, which including next servers:
Name / Host / Port / Deployments
P6 / localhost / 0001 / P6(v8.3), p6ws1(v8.3)
p6ws2 / localhost / 0002 / p6ws2(v8.3)
Now we have two different file BREBootstrap.xml.

OK, so I got this to work this morning with Username Token Profile (with little help from Oracle Support).
I followed your steps 1-4 but in step 2 I didn't add the -Ddatabase.instance=2 because I want to check to see if my code could swap between different instances.
It appears for Username Token Profile to use Database Instance, you need to set it in the soap header.
