How to call SAP Webservice in standalone java program

In our Java application, we want to use the SAP Webservices. I dont know much about authentication mechanism used by SAP. Can any one please help me with any sample code how to Call SAP webservice in Standalone Jave Program. I searched alot on the web regarding this, but helpless. Please help me.

Hi Mohan,
You need an account for the ES Workplace. I'm afraid this is not free, e.g. check [SAP NetWeaver, Composition Subscription|https://www.sdn.sap.com/irj/sdn/subscriptions/composition].
But I thought you wanted to play with a WSDL [you already had at hand|Sample code to access BAPI Web services from JAVA required;?

This depends on the version of your Netweaver Java AS. If you are running 7.0, you will have to use the Jco framework. The Jco framework is deprecated since 7.1 though. If you want to build a RFC server in 7.1 or higher, it is adviced that you set it up through JRA.
Implement an RFC server in 7.0:

How to call a webservice (e.g. MII)?

I am looking for information how to call a webservice (e.g. a transaction in SAP MII) in SAP ME. For example, I have to call a webservice when the user clicks the "Start" button in a POD. Is this something I can only achieve by implementing my own activity hook? Is there a documentation about this topic?

Hello,
I try to do the same, calling a MII Webservice from a collaboration plug-in...
Based on my WebDynpro experience, I was expecting to have to reproduce almost the same code, so in the transporter, I write this code :
          MyWebService ws = new MyWebService();
          InputParams inputParams = new InputParams();
          XacuteRequest xacuteRequest = new XacuteRequest();
          // inputParams.setIFEQUIPMENT(inputInformation.getString("RESOURCE",""));
          inputParams.setIFREPORTEDBY(inputInformation.getString("USER",
                    "Unknown"));
          xacuteRequest.setLoginName(Constants.LOGIN);
          xacuteRequest.setLoginPassword(Constants.PWD);
          xacuteRequest.setInputParams(inputParams);
          try {
               XacuteResponse xacuteResponse = new XacuteResponse();
               xacuteResponse = ws.getMyWebServicePort()
                         .xacute(xacuteRequest);
          } catch (Exception e) {
               returnData.put("EXCEPTION", e.toString());
               returnData.put("SUCCESS", "false");
               returnData.put("ERROR_MESSAGE", e.getMessage());
But when executing, I got the error message "can not authentificate the user" (on the local Netweaver, it doesn't reach the MII platform)
Any idea ? Who can give me a complete example of calling an MII web service ?
Thanks
Olivier

How to call a webService from WebDynPro ABAP ?

We are trying to call a webService from WebDynPro-ABAP application. It is not working, While if we are calling the WebService from a Report, it is working.
How exactly do we call a WebService from a WebDynPro-ABAP application?
What are the main steps involved ?

Hi Phani,
You will need to create a service call as follows.
Right click on your WD component name and select Create->Service Call
The wizard will guide you through a series of steps to make a Web Service Call. On the 3rd screen, it will give you options such as Function Module, Web Service, etc
Before making a service call, you will need to create a proxy for the Web service in the ABAP Workbench using a WSDL document as a basis. To create or consume Web services, you will need the authorizations associated with the role SAP_BC_WEBSERVICE_ADMIN.

How to call a WebService method using HttpsURLConnection?

Hi,
I want to know how i could use HttpsURLConnection to call a WebService method.
I can use the following:
String endpoint = "https://xyz:8443/axis/services/MSecurity";
System.setProperty("javax.net.ssl.keyStore", keyStorepath);
System.setProperty("javax.net.ssl.keyStoreType", "PKCS12");
System.setProperty("javax.net.ssl.keyStorePassword", keyStorePassword);
System.setProperty("javax.net.ssl.trustStore", trustStorePath);
System.setProperty("javax.net.ssl.trustStoreType", "JKS");
System.setProperty("javax.net.ssl.trustStorePassword", trustpass);
//Call Web Service
URL url = new URL(endpoint);
MSecuritySoapBindingStub service = new MSecuritySoapBindingStub(url, null);
//get list of people
String[] vo = service.getVO();
for (int i = 0; i < vo.length; i++) {
System.out.println(vo);
However, loading my cert. this way is not flexible. Therefore, I am using SSLContext to initialize my keystore and truststore and then I am using the following to connect to my webservice:
SSLContext sc = SSLContext.getInstance("SSLv3");
sc.init(kmf.getKeyManagers(), tmf.getTrustManagers(), null);
SSLSocketFactory ssf = sc.getSocketFactory();
URL url = new URL(endpoint);
HttpsURLConnection htp = (HttpsURLConnection) url.openConnection();
htp.setSSLSocketFactory(ssf);
However, I do not know how I could use the "htp" object to call the getVO() method above.

Use Apache Axis to do SOAP in Java.
Nobody can just mail you the code. You first have to create java source files from the web service via its WSDL file.

How to consume json webservice in abap?

hello every one please help me how to consume json format webservice in abap.
i am new in abap please help me out .
Thanks&Regards
~Ahmad

hi check this,
First create a web service in SAP. The blog by Uwe Kunath descibes this clearly. Then create an Xcode project and use the ASIHTTPRequest wrapper to connect to the web service. Parse the response with the KissXML parser. A more out of the box solution is NetWeaver Gateway. It also let you use SAP web services but it also generates iOs code for you. SAP just released a trial version in de download section.
Example of ASIHTTPRequest
- (void)getFlightData:(NSString *) selectedDate {
     NSURL *url = [NSURL URLWithString:@"http://abap.sapdev.nl:8000/sap/resources/flights/from/%/to/%/date/20110128?sap-client=001"];
     ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
     [request setUsername:@"BCUSER"];
     [request setPassword:@"minisap"];
     [request startSynchronous];
     NSError *error = [request error];
     if (!error) {
          NSString *response = [request responseString];
          [self parseXML:response];
Example of KissXML
-(void)parseXML:(NSString*)source {
     NSError *error = nil;
     DDXMLDocument *theDocument = [[DDXMLDocument alloc] initWithXMLString:source options:0 error:&error];
     NSArray *results = [theDocument nodesForXPath:@"/asx:abap/asx:values/TAB/BAPISFLDAT" error:&error];
     for (DDXMLElement *flightdetail in results) {
          NSString *airlineid =   [[flightdetail elementForName:@"AIRLINEID"] stringValue];
          NSString *airline =     [[flightdetail elementForName:@"AIRLINE"] stringValue];
