Web services and unbounded item

Hi all,
I'm not able to invoke web services in WD application when there are items with maxOccurs set to unbounded.
The error is:
com.sap.engine.services.webservices.jaxrpc.exceptions.XmlMarshalException: XML Serialization Error. Array Property [car] in class [none] must not have NULL elements. This is restricted by schema description.
In this case item "car" is set in wsdl as
<xsd:element name="car" minOccurs="0" maxOccurs="unbounded">
Any ideas?
thanks
Andrea

hi, i�m doing something like you but in jbuilder that is another IDE, i don�t know if it is useful for you but i entered to the help of jbuilder and i wrote in the index "web services" and then i found a topic called : "export classes as webservices" and in that place i can see some steps to follow, may be in eclipse you can find something like this.

Siebel OnDemand Web Services and BPEL II

We are trying to do a POC for a given client that is trying to decide between SOD and another on demand CRM product.
Our POC is to integrate SOD using bpel and sending data to a back end system with SOD as the originator and instigator of the flow.
We intend to take data from an integration event pull it into bpel do a transformation to add data to it and update SOD to complete the circuit.
We are having a few issues and was wondering if you can provide some insight since we would like to put SOD at this site.
Our issues are :)
Issue 1
When we import the WSDL for the Integration event the scheema's are not resolved.
Issue 2. When we import more than one WSDL in our flow it has issues with duplicates between the 2 wsdls..
issue 3.
We have succesfully used the example application to do our login and faked out the endpoint but have not been able to automate this step.
We found an example online at oracle ( http://www.oracle.com/technology/tech/fmw4apps/siebel/ofm-siebel-blog-postings.html)
(We got that link from the other BPEL post: Siebel OnDemand Web Services and BPEL
But when we copy the code into our embeded java object it doesn't work. I think that we may be missing some of the code to use.
Do we have the full copy of this java object?
here is hte error that we get from bpel
Exception reported is: Siebel_On_Demand.bpel:33: Class bpel.p0.URL not found.
URL wsURL = new URL(wsLocation + "?command=login");

I'm also trying to do this.
Some info from the Siebel web services guide:-
"The login request is an HTTPS request to instantiate a session and obtain a session ID. A client invokes login by sending an HTTP GET request to a URL like the following:
https://secure.crmondemand.com/Services/Integration?command=login
NOTE: The login parameter value is case sensitive.
■ Login input. The input to login is provided in the URL parameters and the HTTP headers, as follows:
■ The only URL parameter to be set is command. This parameter value is login.
Two HTTP headers, UserName and Password, must be set with the appropriate values for your system. For example:
❏ UserName: [email protected]
❏ Password: mypass
■ Login output. The login command returns the following items:
■ A session cookie, jsessionid. The client must use this cookie when submitting subsequent requests, including logoff requests.
■ A status code of 200, if the session does not encounter any errors. This indicates that the request succeeded.
Then to get data out ....
Integration request input. The jsessionid returned to the client during login must be included with the request. The request must contain the jsessionid either as a cookie or as a URL parameter, as follows:
https://secure.crmondemand.com/Services/Integration/object;jsessionid=xyZ12489w3482413
Does anyone have any ideas on how we might do this using the Oracle BPEL PM?
Thanks in advance.

Diff b/w Web service and window service

What is the difference between web service and window service, whether the both are same or not, Give some explain about that each one and give some examples also.

An XML Web service is a component that implements program
logic and provides functionality for diseparate
applications. These applications use standard protocols,
such as HTTP, XML, and SOAP, to access the functionality.
XML Web services use XML-based messaging to send and
receive data, which enables heterogeneous applications to
interoperate with each other. You can use XML Web services
to integrate applications that are written in different
programming languages and deployed on different platforms.
In addition, you can deploy XML Web services within an
intranet as well as on the Internet. While the Internet
brings users closer to organizations, XML Web services
allow organizations to integrate their applications.
A Windows service starts much before any user logs in to
the system (if it has been setup to start at boot up
process). A Windows service can also be setup in such a way
that it requires a user to start it manually ? the ultimate
customization!
Windows services run as background processes. These
applications do not have a user interface, which makes them
ideal for tasks that do not require any user interaction.
You can install a Windows service on any server or computer
that is running Windows 2000, Windows XP, or Windows NT.
You can also specify a Windows service to run in the
security context of a specific user account that is
different from the logged on user account or the default
computer account. For example, you can create a Windows
service to monitor performance counter data and react to
threshold values in a database.

Pl/Sql web service and collections not working

Web service and servlets in the same project...web.xml?

Hello, I have a problem with my web service.
I have a server, which displays a web service. I programmed this service with JAXRPC.
I have a client, in another directory. I succeded in compiling, deploying and running the web service.
The problem is that after I tried to integrate this service in an existing project. This project contains servlets. In these servlets, I'm using sessions.
These servlets are on the same side as the server of the web service. Because of the implementation of my code, I'd like to use in the class that represents the server of the service, the same session as the one I'm using in the servlets.
But of course, it's not working by itself. I know there's something to do with the web.xml files.
The thing is that I created a web.xml file for the service, and another for the servlets.
I was thinking of joining both of them in one xml file, but everything crashes then...
Could someone tell me how to create a project with a web service and servlets, and mostly how to configure the xml file??
Thanks for any help

Quick questions on the topic of Web Services and EJB POJOs

I have been reading about Web Services and the data types that are aloud as operation parameters and return types. I was wondering what the standard practice for return types; is it to use the Entity classes straight and customize the WSDL instead of letting the EE container do it (avoid cyclic problems in the schema that can occur when using entity 1-to-many and many-to-1 mappings) or; is it to off load the data into a DTO/VO/Bean and let the EE container take care of all the schema mapping for the WSDL? I look at the EE tutorial and bought a EE book both use very basic examples that do not include connecting to a database or using EJB3 for the data store.
Thanks for any information

not being able to understand where i made the mistake. mistake is in the code of web service end or in calling code?
help me to fix this issue. thanks

Hi Mou,
I just tried your win app code about calling web service, but failed. I got the 500 error after I called your service:
The error message I quoted from Fiddler:
<?xml version="1.0" encoding="utf-8"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"><soap:Body><soap:Fault><faultcode>soap:Client</faultcode><faultstring>System.Web.Services.Protocols.SoapException: Failed : Invalid credentials ---> System.Exception: Invalid credentials

I am not totally sure that error occurred by the authentication. But I suggest you can try to add this service into your project using this method below:
1.right click the Reference and select Add Service Reference
2.input your service link and click "Go"
And you can use this service as the following:
private async void callService()
ServiceReference1.SearchDataIndexSoapClient client =new ServiceReference1.SearchDataIndexSoapClient();
var Str= await client.StartIndexAsync(new ServiceReference1.AuthHeader { Username = "Admin", Password = "Admin" });
Please try it.

How to connect to external web service and convert XML to a table

Hi experts,
I need to connect to external/non-SAP web service and convert XML in that site to a SAP table?
Is there a function call(SE37) to do this? Is it a must for me to install AS JAVA or PI and configure enterprise service? Please provide a link for me to retrieve relevant infomation, thx.

No, you don't need PI or the Java stack for this. You can create an ABAP proxy using the WSDL file for the web service and call the web service using the proxy class in an ABAP program. You can transform the XML response to internal tables/structures/variables using a transformation template that you create.

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.

Web services and control characters

Hi,
We are using JAXWS and JAXB to create web services. We have a problem with our current data because it sometimes contains "bad" characters, such as control characters. Is there a nice way for us to remove these characters when creating the messages or when retrieving the data from the database? We use java persistence / hibernate to retrieve the data from the database.
I would prefer a method that doesn't include having to "clean" each string manually...
Thanks!

Need advice about web services and Java beans

Hi
I am very new to web services and to Java beans as well.
I am trying to understand if and how a web service can use functionality I have in a Java bean. I couldn't find any documentation I can use.
For example:
InitialContext ic = new InitialContext();
Adder adder = (Adder) ic.lookup("ejb/AdderJNDI");In a EJB client project (I'm working with Eclipse) if I add the EJB project to the build path, the Adder interface is recognized.
Theoritacally I thought I can do the same in a web service server project, but the Adder interface is not recognized.
Is there something I can read to understand how I need to use the EJB or implement the web service?
Many thanks
Sigal

Okay....I think I made some errors with the original scenario:
It basically comes down to this....I think. OCS Calendar has a set of Java classes and methods that provide an abstraction for their web services interface. I know how to create something to use these classes using an IDE like JDeveloper, but I'm not sure how that would work with HTML DB.
I've noticed that the SQL Workshop has a place for Java sources and classes, and I've heard mentions of PL/SQL wrapping. Is there a way to import classes into an HTML DB workspace, wrap 'em up, and access them via PL/SQL?
Thanks again,
Jonathan

Load balancing SMA web service and SMA end point URL

Hi,
We have set up the recommended 3 servers with Azure Pack, SMA Web Service and Runbook Worker. We are now wanting to configure the Azure pack portal to setup the SMA endpoint url for the web service. Before we do that, we are assuming we should
load balance the web services to answer on 1 url (ie, smaws.domainname.com).
1. Is there any guidance or things to consider when load balancing the 3 web services to answer to 1 url. We will probably use f5 since that is what we use.
2. The end point url that we configure for Azure Pack automation should be this load balanced URL correct?
3. Should we have the Azure pack installed on just one of the servers or all 3. We did all 3 but it seems like server2 and 3 just redirect to 1 anyway so I am assuming the URL for Azure pack is stored in a db somewhere.
4. Are there any other components of SMA/Azure Pack that should also be load balanced?
Thanks
Thanks Lance

So in this case you need to register the SMA Runbook Workers (do this on machine 1):
$webService
= "https://localhost"
$workers
= (Get-SmaRunbookWorkerDeployment
-WebServiceEndpoint
$webService).ComputerName
if($workers
-isnot [system.array]) {$workers
= @($workers)}
$workers
+= "MachineName2"
$workers += "MachineName3"
New-SmaRunbookWorkerDeployment
-WebServiceEndpoint
$webService -ComputerName
$workers

[jaxrpc] defining web services and WSDL spec

Greetings,
I'm starting in JAXRPC web service's concepts and its WSDL specification. After I tested some samples from the jaxrpc tutorial, I tried to make my custom web service, but, I have problems when I deploy the web service and I tried to see in my browser the endpoint url - I got a internal server exception! I pick up the hello sample, I added to it my custom core sample web service functionality - using the same operations, the same signatures methods - and it worked fine!!
So, what' is wrong? The main difference between them is that I have differents configuration files for xrpcc that will give a wsdl files for each one. Whats changes? The service name? The interface/package name? Is there some kind of limitation in the package name convention with the service names beyound the basic ones in the xrpcc (jaxrpc) specification?
thanks,
Pedro Salazar.

I upgraded webservices developer pack to 1.0 version (final) and I solved my problems!

Web Services and Internal Tables.

Hi.
In the next days I will need to create a program to consume a Web Service that is going to return data like an internal table, I mean...
Field1a | Field2a | Field3a
Field1b | Field2b | Field3b
Field1c | Field2c | Field3c
Do you have any ABAP example of consuming a Web Service and receiving data into an internal table?
Thanx in advanced.
