Service Endpoint Interface (SAP Library

Service Endpoint Interface

Use

The Service Endpoint Interface (SEI) exposes the business methods provided by a particular Web service. It is generated from the WSDL port type and named after the port type. The way the methods are generated depends on the port type and the JAX-RPC 1.0 conventions.

Features

For SAP Web AS Java Web service clients, an additional option is provided – generation of RPC-style SEI for document/literal-style WSDLs. In this case, for each generated method that has only one wrapper parameter for the input and one wrapper parameter for the output, an additional method is generated that has the same name but the input and output parameters are unwrapped in the signature.

Syntax

package example.client;

public interface CalendarServiceRpc extends java.rmi.Remote,javax.xml.rpc.Stub {

public float add(float p1, float p2) throws java.rmi.RemoteException;

public float div(float p1, float p2) throws java.rmi.RemoteException;

}

Activities

The following settings can be configured in the Logical Port editor in the SAP NetWeaver Developer Studio:

· Endpoint URL

Syntax

client._setProperty("javax.xml.rpc.service.endpoint.address",

"http://newhost.com:8080/webservice/newLocation");

· HTTP proxy host and port

Syntax

port._setProperty("javax.xml.rpc.http.proxyhost","proxy");

port._setProperty("javax.xml.rpc.http.proxyport","8080");

· HTTP Basic Authentication

Syntax

client._setProperty("javax.xml.rpc.security.auth.username","username");

client._setProperty("javax.xml.rpc.security.auth.password","password");

· Request and response logging – specifies the streams in which the requests and responses are to be logged. This property should be set for debugging purposes only, otherwise it will decrease the server performance.

Syntax

client._setProperty("RequestLogging", System.out);

client._setProperty("ResponseLogging", System.out);

· Socket timeout – specifies the connection timeout in milliseconds.

Syntax

client._setProperty("socketTimeout", "30000");
