FlaresA Tutorial on RPC Vs Document Style WSDL SOAP binding with Example. When you create Web Services using SOAP protocol, you follow either Document or RPC SOAP messaging style. In this article, let us discuss about the difference between the Document and RPC style web services. We use sample example programs which is developed using JAX WS API from Java.

The framework is. If you really want to understand soap web services, do try using JAXWS. Using axis and Eclipse hides important points required for developing real world applications. Basics Document Style Vs RPC Style The Document style indicates that the SOAP body contains a XML document which can be validated against pre defined XML schema document. RPC indicates that the SOAP message body contains an XML representation of a method call and uses the names of the method and its parameters to generate XML structures that represent a methods call stack. The documentliteral approach is easier because it simply relies on XML Schema to describe exactly what the SOAP message looks like while transmission.

SOAP Encoding is an extension of the SOAP framework. SOAP encoding offers rules to convert any data value defined in SOAP data model into XML format. What is Literal In simplest definition, literal it means that the data is serialized according to a schema. Learn by doing Document Vs RPC Web Services and Artifacts Examples WSDL,Schema, SEI.

This means the schema alone does not tell you what the message body Info set contains because some of the soap body contents comes from WSDL definitions. Because of this, schema describing an RPCliteral message is not sufficient to validate that message. From the above request and response you can see that the Soap Body contains one element which has the name of the WSDL operation and the namespace specified on the soap body element in the WSDL binding. Reactance Calculator Program. Inside this element, theres an element for each part of the message and its name is name of the part. Inside each part element are the contents of that part, as defined by the schema type that the part references in WSDL. For example see the above response. Thelt ns. 2 get. Greeting. Request. Response xmlns ns. WSDL operation and the namespace specified on the soap body element in the WSDL binding. Inside this you can see the part element Greeting. Response and its content is as per the defined schema. Notes on RPC ENCODED Style and JAX WS In JAX WS RPCencoded is not supported as a messaging mode. In JAX WS the encoded encoding style isnt supported and only the literal encoding style used. If you use wsimportwsgen on wsdl documentsSEI that has useencoded attributeSOAP binding you may get the following error,. SOAP Binding annotation. Rpcencoded SOAPBinding is not supportedOr rpcencoded wsdls are not supported in JAXWS 2. You can use JAX RPC or Apache Axis V1, f you want to send SOAP encoded messages or create RPCencoded style WSDL. DocumentLiteral SOAP Binding Web service Let us now change the style to Document and see the generated schema files and WSDL files. There are two schema files generated and are included in the WSDLfile. The SEI. author Binu George. Globinch. com. Visit http www. All rights reserved. Web. Method. import javax. Web.

What is an IDocIDoc or Intermediate Document is an SAP document format for business transaction data transfers. This blog describes the detailed steps to be followed for setting up and sending an IDoc from an SAP R3 system to SAP BPM via SAP PI  in a Process Orchestration setup. An IDoc cannot be directly imported into SAP BPM. The WSDL generated from an imported IDoc in ESR is not WS I compliant hence you may face runtime issues when BPM tries to consume the service interface created of IDoc type. Let us see how we can overcome this constraint and have the scenario run successfully. Creation of Design objects. Creation of wsdls. The IDoc we import from an SAP R3 system will be used on the sender side but we cannot use this on the receiver side BPM because it is not WS I compliant as mentioned in the earlier section. We need to modify certain tags before using it on the receiver side. Note 1. 41. 42. 92Import the IDoc from corresponding R3 system in ESR. Open ESR,  right click on Imported objects, provide R3 system details and import IDoc A This will be used in the sender interface let us denote this as A. After the import is successful, open the IDoc, switch to the WSDL tab and Export the WSDL into a file. Make a copy of the WSDL and edit it to reflect the following changes Set the target. Namespace attribute to urn sap com document sap idoc messages and xmlns attribute to urn sap com document sap idoc messages for the xsd schema. Set the xmlns attribute to urn sap com document sap idoc messages for the lt WSDL definition element. Refer to the image below for an example. Import the modified WSDL as an external definition. BThis will be used in the receiver interface let us denote this as B. Save and Activate all the changes. Note To set a relevant type for a data object in BPM for an element, there needs to be a name associated with the complex type. For example. Below is the structure of the exported idoc in ESRlt xsd element nameHRCC1. UPTEVEN0. 1 lt xsd complex. Type lt xsd sequence lt xsd element nameIDOC typeHRCC1. UPTEVEN. HRCC1. UPTEVEN0. Type We need to have an associated name to the complex type as shown below. HRCC1. UPTEVEN0. 1 typenamedexamplecomplextype lt xsd complex. Type namenamedexamplecomplextype lt xsd sequence lt xsd element nameIDOC typeHRCC1. UPTEVEN. HRCC1. UPTEVEN0. Type Creation of Service Interfaces. Create these Interfaces with the listed attributes. Save and Activate all the changes. Creation of Mappings. Create a Message Mapping with source as IDoc A and target as External Definition B Note This is required as the sender and receiver do not use the same schema. Perform the mapping with the corresponding field. Create an Operation Mapping with source as Sender Interface SIA and Target as Receiver Inteface SIBAssign the message mapping to this operation mapping. Save and Activate all the changes. Creation of Integration Flows. Create an Iflow with following attributes. Assign the operation Mapping created to this integration Flow. Save, Activate and deploy all the changes. Modelling BPM Process. Create a new Process Composer Development Project. Import the SIB from ESR under service Interfaces tab. The data types should be created under a namespace urn sap com document sap idoc messagesAssign this to the SE of the BPM Process. Create a data object and map in Output Mapping. Build and Deploy the processes Note The WSDL might have errors  as s. Invalid attribute value for max. Occurs in element element. Recorded reason cvc datatype valid. Negative. Integer. This can be ignored. Sending IDoc from R3 System. Trigger the IDoc from the R3 system. Monitor the messages using the Message Monitor page in NWA. Verify that they have been delivered. The BPM Process should be started and the context data should be updated in the corresponding sent fields. This can be monitored in Manage Processes Page in NWA.
