ESB and Webserivces RPC/ encoded

Hi,
i know i can not handle Webserivce with RPC/encoded format on BPEL without a BPEL proxy - how it looks on the ESB - exist here the same problem?
Best regards
Thomas

ESB only supports single part WSDL and document literal in 10.1.3.1. I don't know of any workarounds but it is working in AS11 prototype but that likely won't comfort you much. Sorry.

SOAP adapter and WS with rpc/encoded

Hi All,
Does anyone know if and how the SAP XI 3.0 SOAP Adapter supports WebServices which expects XML messages in rpc/encoded.
Cheers,
FRank

Hi Frank,
I have the same issue and I got a reply from OSS:
This problem is caused by the diversification of the WSDL binding
styles.
A Web service is described by a WSDL document. A WSDL binding
describes how the service is bound to a messaging protocol, particularly
the SOAP messaging protocol. A WSDL SOAP binding can be either an RPC
style binding or a document style binding. A SOAP binding can also have
an encoded use or a literal use. This gives us four style/use models:
- RPC/encoded
- RPC/literal
- document/encoded(It will probably disappear from future versions of
WSDL.)
- document/literal
RPC styled web services have serious interoperability problems. This
is the reason that the rpc style is not in the basic profile
specification of the web interoperability and also it has been
deprecated in the current soap specification. For these reason, the
integration directory does not currently support the RPC style! I would
suggest you to use other document style web service provider if possible
. It's the best way to solve this problem. But if you persist in using
this RPC web service provider, we still have a workaround solution:
you need to convert your RPC wsdl to a document styled wsdl and import
it to the directory and if necessary, you need to add some mapping to
solve some RPC interoperability problems.
In your case,
1. The WSDL file you used is RPC style.
2. The XI SOAP adapter doesn't support the RPC style. It only sends the
document/literal SOAP message which can't be understand by your web
service provider.
One of the significant differences between the SOAP message of RPC
style and that of the document style: the operation name is contained in
the RPC style SOAP message but not in the document's.
However, you can't solve this problem by simply specify a method
name. What you should do is convert your RPC wsdl to a document styled
wsdl. RPC turns out to be a subset of document/literal. This
means for any given RPC WSDL, you can create a completely
equivalent document/literal WSDL that would describe the same wire
messages. Here are the steps for doing this (mostly schema element
declarations).
Solution:
For each RPC operation:
1. For each part in the input and output messages of that operation,
declare a type with the contents described in step 2.
2. Declare an element with the name of the part, the type referenced by
type=". The element form must be unqualified.
3. Declare a global element with the operation name and the namespace
from soap:body/@namespace in the binding. Make the type of this element
the one defined in step 1 for the input message.
4. Declare a global element with the operation name and the word
Response appended to it and the namespace from soap:body/@namespace in
the binding. Make the type of this element the one defined in step 1 for
the output message.
5. Change the input message to contain one part and reference the
element you declared in step 3.
6. Change the output message to contain one part and reference the
element you declared in step 4.
7. Change the style to document in the binding.
After that, import the new WSDL file to the integration directory. You
will find the "method name" appears in the document style SOAP message.
But actually it's the name of the input element which is the same as
the name of the operation. It's just a little trick.
Cheers Stefan

How to handle rpc/encoded style messages using BizTalk?

I am integrating with a lot of services and one of our customers has a service with rpc/encoded style
I could consume and generate schema from their wsdl file via BizTalk consume WCF wizard.
Once I am trying to call the service with request message that generated from the schema, it is giving an error that can not desterilize the first element of the message.
No Deserializer found to deserialize a 'FieldName' using encoding style 'null'
I compared the stub xml request message from SaopUI and I noticed that the xml expecting the data type with the element like this .
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsb="WSBanka">
<soapenv:Header/>
<soapenv:Body>
<wsb:bnkBorcsorgulama soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
<sozlesmeNo xsi:type="xsd:string">?</sozlesmeNo>
<bankaKodu xsi:type="xsd:string">?</bankaKodu>
<anahtar xsi:type="xsd:string">?</anahtar>
</wsb:bnkBorcsorgulama>
</soapenv:Body>
</soapenv:Envelope>
On the other hand, I got the request of the message from Fiddler using the BizTalk , and the generate xml of the BizTalk schema without the data type.
<soapenv:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsb="WSBanka">
<soapenv:Header/>
<soapenv:Body>
<wsb:bnkBorcsorgulama>
<sozlesmeNo>?</sozlesmeNo>
<bankaKodu>?</bankaKodu>
<anahtar>?</anahtar>
</wsb:bnkBorcsorgulama>
</soapenv:Body>
</soapenv:Envelope>
In SoapUi, if I remove a datatype from the message, I will get same error from the BizTalk request.
I read some articles that rpc/encoded style are not supported but I am not sure and these articles are not clear.
I also read that it was supported with Soap adapter but now it is deprecated.
So, Is there any one has an experience in rpc/encoded style messages and how to handle these message in BizTalk or is there any work around to handle these messages?
Your inputs really appreciate it.

Exceptions are using rpc/encoded messages in documentwrapped mode

Version: Weblogic 8.1SP3
I exposed a web service in documentwrapped(/literal) mode, and it seems weblogic is using rpc/encoded convention instead, to serialize Exception.
I posted more infos on the Axis bugtracker : http://nagoya.apache.org/jira/browse/AXIS-1576
but I found later that the problem seems to come from Weblogic.
Does someone know a workaround for this problem ?

Hi Shabrish,
As per the details from MQ Server technical guys, thread is opened by admin user of PI to put the messages on queues of MQ server and that thread does not get close itself and keep on hanging the message in Delivering Mode. Because of this issue all messages behind it get queued to Delivering mode .And as soon as we restart the Java Stack it gets flushed up and open the new connection and deliver all old messages but new message again get stuck in Delivering Mode.
Any idea on this.

Problem with RPC/encoded WSDL

I'm having trouble calling a web service that is based on an RPC-encoded WSDL. I've already made slight changes to the WSDL, so that I get a work-able message type for mapping purposes. These changes are based on <a href="http://www.ws-i.org/Profiles/BasicProfile-1.0-2004-04-16.html#refinement16556272">soapenc:Array recommendations in WSDL 1.1 Section 2.2</a> for declaration of array types.
Here's a snippet of the WSDL:
<wsdl:definitions ...>
<wsdl:types>
 <schema ...>
 <complexType name="ArrayOf_tns1_ServiceOption">
 <complexContent>
 <restriction base="soapenc:Array">
 <attribute ref="soapenc:arrayType"
 wsdl:arrayType="tns1:ServiceOption[]"
 xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"/>
 </restriction>
 </complexContent>
 </complexType>
 </schema>
 <schema ...>
 <complexType name="ServiceOption">
 <sequence>
 <element name="key" nillable="true"
 type="xsd:string"/>
 <element name="value" nillable="true"
 type="xsd:string"/>
 </sequence>
 </complexType>
 </schema>
</wsdl:types>
</wsdl:definitions>
I've changed it to:
<wsdl:definitions ...>
<wsdl:types>
 <schema ...>
 <complexType name="ArrayOf_tns1_ServiceOption">
 <sequence>
 <element name="ServiceOption"
 type="tns1:ServiceOption"
 minOccurs="0" maxOccurs="unbounded"/>
 </sequence>
 </complexType>
 </schema>
 </schema>
 <schema ...>
 <complexType name="ServiceOption">
 <sequence>
 <element name="key" nillable="true"
 type="xsd:string"/>
 <element name="value" nillable="true"
 type="xsd:string"/>
 </sequence>
 </complexType>
 </schema>
</wsdl:types>
</wsdl:definitions>
The above changes have allowed me to make message mappings. But the I still get an error when sending a request to the web service. It seems that it requires the xsi:type and soapenc:arrayType attributes for arrays.
How can I create these attributes? How does XI handle RPC-encoded WSDLs? I haven't encountered these problems with document-literal WSDLs.
Thanks in advance.

Hi Lorenzo,
the extended support of rpc-style does not include the support of soapenc:array. It just addresses the root of the message and its direct children (as discussed in the thread where I added this hint).
In the documentation of External Definitions you can find a hint where to find a list of supported XSD/DTD/WSDL-features. However, also there you will find no hint on the fact that soapenc:array is not supported. The reason for this is, that soapenc:array is specified in none of these standards. It is some artifact that SOAP smuggled into XSD. For good reasons WS-I prohibits the use of this artifact.
Hence, if you need support for argumentation I can only point out the WS-I document I already linked.
Greetings

What is the general way to invoke a rpc/encoded webservice?

Hi,
I have some confusion in invoking webservices, ok, let me explain my question in detail:
Usually, we access a web service througt its wsdl file, for a rpc/encoded style, for example, in Axis enviroment, I will need the java object for the complex message types, how can I get these java files? If I use the Sun provided WSDP tool to compile the wsdl file and get these java files, do they work? If I am not in the Axis enviroment, maybe I will compose the SOAP request directly, so, what is the general way?
Thanks.

Hello,
When you want to invoke a Web Services (RPC or Document style) you generally as you said create a set fo Java class to: map the messages information to Java code, and create a proxy/stub to do the call.
Using Oracle Application Server Web Service framework you have several way of creating this client classes:
- using Oracle JDeveloper just do a File>New>Web Services>Web Service Proxy
- using the command line tool, and associated Ant tasks (WSA:Web Service Assembler), see the Web Services Developer Guide

If you look into the test view you will find a link for a java proxy(click the

Problems with J2ME and JAX-RPC

Hi,
I am trying to write a J2ME web service client. I have generated the stub classes with wscompile from the wsdl document at http://www.webservicex.net/stockquote.asmx?WSDL. However, when I try to run the MIDlet I always get the following error message:
[wtkpreverify] Error preverifying class javax.xml.rpc.encoding.Serializer
[wtkpreverify] java/lang/NoClassDefFoundError: java/io/Serializable
I am using Eclipse 3.1, Antenna 0.9.13, the Web Service Development Kit 2.0 and the WTK 2.3 beta.
The necessary jars (the WTK libs, rt.jar from the JRE, activation, mail, saaj and jax-rpc libraries from the WSDK) have been included in my classpath.
Does anybody know how to fix this problem? Any help is much appreciated.
Regards,
Motivated

Thanks, that was my mistake.
Instead of using wscompile, you must generate the stub classes with the WTK. Then, you set a reference to the j2me-ws.jar (JSR-172). No additional libraries from the Web Service Development Kit are required.

How to read/use RPC/Encoded WSDL in BPEL

Hi All,
We are developing a new application using Oracle BPEL and interface with an existing application.
The existing application (in mainframes) sends us the wsdl in rpc/encoded format.
How to read thie wsdl into BPEL? What we found so far is that we can use document/literal wsdl only.
Is there a way to read rpc/encoded wsdl in bpel?
Or a way to convert rpc/encoded wsdl into doucment/literal format wsdl so that it can be used in bpel?
Or any java code in between which can do this transformation?
Please help.
Thanks
Shiva

Steve,
You need to do the following in order to get file and folder names from File/FTP adapter.
1. fileAdapterInboundHeader.wsdl, FTPAdapterInboundHeader.wsdl files does have header structure for file and FTP adapter respectively. These files have the following Header definition:
<types>
<schema attributeFormDefault="qualified" elementFormDefault="qualified"
targetNamespace="http://xmlns.oracle.com/pcbpel/adapter/file/"
xmlns="http://www.w3.org/2001/XMLSchema"
xmlns:FILEAPP="http://xmlns.oracle.com/pcbpel/adapter/file/">
<element name="InboundFileHeaderType">
<complexType>
<sequence>
<element name="fileName" type="string"/>
<element name="directory" type="string"/>
</sequence>
</complexType>
</element>
</schema>
</types>

<message name="InboundHeader_msg">
<part element="tns:InboundFileHeaderType" name="inboundHeader"/>
</message>
2. You need to create a variable of message type InboundHeader_msg.
 2.a. Open variable creation dialog box. Choose Message Type as type and open the Type Chooser.
 2.b. Expend Message Type and then expend Project WSDL Files.
 2.c. You will see fileAdapterInboundHeader.wsdl/ftpAdapterInboundHeader.wsdl there.
 2.d. Expend the wsdl file and select message type InboundHeader_msg.
3. Now you have your header variable, double click on Receive activity and go to Adapter tab.
4. Select header variable you have created using above steps as Header Variable.
5. Add an assign activity to get fileName and directory from the header variable you have created.
6. Your header variable will be populated while adapter reads the file.

Can SAP handle RPC/encoded WSDLs

I am not sure whether this is the right forum for this question, but i'll give it a try:
I have a WSDL file (web service decription) from a 3rd party tool, which is RPC/encoded, and I tried to generated an ABAP proxy class (SAP Basis 7.01). During the generation I get a couple of different errors, and the one that bothers me most is
"incorrect value for attribute use: "encoded"".
When I replace all occurrences of "use="encoded"" with "use="literal"", then the proxy generation will work, but in this case, the web service call will not work anymore (probably because the encoded response from the webservice cannot be read by the proxy class).
What can I do?
Any hints are welcome.

Hi,
It seems only RPC with literal will be supported in future.
Quote from wiki Please see this:
"Some of these combinations are rarely used in practice, such as document/encoded. In general, the literal use is gaining importance, and as far as RPC/encoded is concerned, the Web Services Interoperability Organization (WS-I) in its Basic Profile Version 1.0a of August 2003 ruled out the use of SOAP encoding with web services. Document/literal and RPC/literal will be the only allowed style/use combinations in the future."

How to create RPC encoded wsdl for the bpel project created in jdeveloper?

Hi,
I have to create a bpel project in jdeveloper with the wsdl of the project in rpc encoded format. By default when we create a bpel project in jdeveloper it creates a wsdl file of document literal format, but i need the wsdl to be rpc encoded format. Please let me know how can i achieve this.
Thanks.

Hi Nico,
Thanks for your reply.
You mentioned to specify type in place of element, from where do you get this type and what more changes we need to do for the entire project to compile well with out errors.
As suggested by you, I changed the element to type and tried to compile, it is giving the below error.
Error:
[Error ORABPEL-10902]: compilation failed
[Description]: in "bpel.xml", XML parsing failed because "undefined part type.
In WSDL at "file:/D:/indu/jdevstudio10134/jdev/mywork/TimerApplication/SelectDB/bpel/SelectDB.wsdl", message part type "SelectDBProcessRequestType" is not defined in any of the schemas.
Please make sure the spelling of the type QName is correct and the WSDL import is complete.
[Potential fix]: n/a.
Please let me know what are all the changes that need to be done to complie the project successfully.
Thanks and Regards.

Supports ORACLE PM RPC/encoded ?

Hello !
Is it possible, that the Process Manager can't handle RPC/encoded style ?
Axis send multirefs, when RPC/encoded style is used by webservices ! The ORACLE PM can't handle multirefs. Is a webservice send a message to a BPEL process, deployed on a oracle PM, and the message from the webservice contains multirefs, the Oracle PM gives a fault like NullPointerException !
Have anybody similar experiences ? Is it posible to configure the Oracle PM handle multiref or RPC/encoded style correct ?
Thanks

I have a bug logged against this issue, bug # is 5990259. However, the service I was calling is no longer available, so development can't reproduce it... If you gave them your example as well maybe they could progress this bug? Anyway BPEL does work with RPC/Encoded, it just doesn't like those multi refs. The company we were interacting with was using WebObjects, which was behaving exactly as in your example, and they changed an option on the web service to get rid of the multi refs and it worked (was still RPC/Encoded).

Calling RPC/Encoded WebService

Hi Experts,
is there a possibility to call an RPC/encoded webservice?
We have configured the SOAP adapter but it only sends Document/literal SOAP messages.
XI creates the following message:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
 <SOAP-ENV:Body>
 <ns0:SoapIn xmlns:ns0="urn:test">
 <userName>user</userName>
 <password>pass</password>
 </ns0:SoapIn>
 </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
What we need is:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

 <userName xsi:type="xsd:string">user</userName>
 <password xsi:type="xsd:string">pass</password>
 </ns0:SoapIn>
 </SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Any ideas are welcome!
Thanks for your help,

Hi,
I have for some occasions when I have had a need for "non-standard" SOAP messages used the Plain HTTP adapter and an additional XSLT mapping to create the necessary SOAP tags. Ex. I have used this for adding SOAP-Header tags etc, but I guess you might try this for your needs also. I just created the extra XSLT mapping which takes care of the SOAP wrapping and place that as a second mapping step in the interface mapping.
Kind regards Johan Göthberg
