Use AXIS2 to invoke SAP-generated webservice (with user password Authentication)

The project is exposed to the WebService interface generated with the SAP system, and the interface address is as follows:

Http://12.12.12.12:8000/sap/bc/srt/wsdl/srvc_55FDB689239112C0E10080000AF6031B/wsdl11/test/ws_policy/document? sap-client=400

This form of interface directly via Axis AXIS2 calls the address in a way that cannot be called successfully, reporting the following error

The reason for this error should be that the generated interface does not conform to the WSDL specification.

Service side in parsing the error, then there are other ways to call this type of SAP interface.

After a variety of searches on the web, we found that only AXIS2 generated local code.

1. First go to Apache official website download axis2, I download is axis2-1.5.6, unzip the file, then configure the win7 system environment variable, create a new axis2_home, and enter the AXIS2 path in the variable value "E:\axis2-1.5.6"

2. Access the SAP WebService address, right-save it as an XML file, and then change the suffix name to. WSDL, my file name is document.wsdl. Put it in the bin directory of Axis2 "E:\axis2-1.5.6\bin"

3. Generate the local code for the WSDL file. Open cmd, enter "E:\axis2-1.5.6\bin", enter command Wsdl2java-uri document.wsdl-p com.crm.sap.webservice.feedback-o Feedback

The Wsdl2java command uses

4. Create a Java project with Eclipse and copy the generated code to the project's SRC, as shown in

Bring all jars under the Axis2 directory (E:\axis2-1.5.6\lib) into the project

5. Create a class containing the main method to test, the code is as follows

<span style= "FONT-SIZE:14PX;"

The reason for the above error is because the interface requires user name password authentication, but in the generation of code is not generated to set the user name password Authentication code, then this need we manually added. You can add the authentication code to the following location

/** * * */package test;

		} catch (Exception e) {e.printstacktrace (); }}} </span>

can also in the Ztihosqstub class of the lowest construction method, see the source code discovery construction method is a layer, find the most low-level call construction method, join the user name Password authentication can ensure that other construction methods can also use the User name password authentication
