Java integration to Siebel Webservice


A few weeks back we had this requirement to have a Java client connect to our Siebel Webservice and do various operations. In this model, the Siebel side was the backend, and a Java applet was the frontend to the system. I setup the inbound Webservice in Siebel in no time, using ASIs. But the Java folks were having problems in setting up a connection to the system. They even said there were problems in the WSDL and Webservice, and that they were getting various parser errors on their side. Guess they were too dependent on eclipse, and they could not find an import WSDL feature on it !!

Truth is, Java is one of those languages which understands webservices very well, and if properly used, could make the integration work easiest to implement. You don’ have to build the SOAP request by hand (though, that is one option) as is done in some scripting languages. You just have to figure out how to generate the stub file, or the necessary class files into the system.

Now there are two ways to import a WSDL into a  Java system, you would use the WSDLtoJava.bat file if you are using the apache axis framework. This is when a Java servlet on Tomcat/Apache is talking to another server. I preferred the easier way to using the wsimport command as this is a simple client talking to a Siebel server. I will be using the Service Request ASI WSDL from a previous post.

You need to have the Java SDK installed and the paths properly configured on your system. Open up a command prompt window and type in  “java  -version” or “javac” to see if the paths have been added correctly.

Go ahead and import the wsdl using the command wsimport SR_WSDL.wsdl. Here I am running the command from the root of C: drive. You will see the importer at work generating class files.


You can ignore any warnings you see as long as you don’t get any errors. wsimport would have created a nested folder structure with multiple class files. Here the path created is C:\com\siebel\xml\sm_servicerequest.


Now its time to start writing your main java file which will make an instance of these class files and trigger the integration to siebel. You will have to know which class represents the webservice, here it is SMServiceRequestWS_Service.class. You can also generate the actual java files to see how the class and methods under them have been defined. Inorder to do this, use the command wsimport –keep.


This time wsimport will create the java files for each class file.


Back to our main java file. Import the generated class files using:

import com.siebel.xml.sm_servicerequest.*;

As can be seen, this string is actually the path of the generated class files. This is what my final file looked like :


import com.siebel.xml.sm_servicerequest.*;


//the above namespace is from the generated code from the wsdl.

public class Client


static SMServiceRequestWS_Service service = new SMServiceRequestWS_Service();

public static void main(String[] args)




Client client = new Client();



catch(Exception e)





public void doTest(String[] args)




SMServiceRequestWS pm = service.getSMServiceRequestWS();

// Building the Request hierachy

QueryPageSRInput req = new QueryPageSRInput();




ListOfSmServicerequest list = new ListOfSmServicerequest();

ServiceRequest SR =new ServiceRequest();



// Variable to store Response hierarchy

QueryPageSROutput res = new QueryPageSROutput();

// Invoke the service

System.out.println("Invoking the Webservice ");

res =pm.queryPageSR(req);


for (int i = 0; i < res.getListOfSmServicerequest().getServiceRequest().size(); i++)


System.out.print(res.getListOfSmServicerequest().getServiceRequest().get(i).getStatus() + "\t");

System.out.print(res.getListOfSmServicerequest().getServiceRequest().get(i).getSRNumber() + "\t");




catch(Exception e)







All the information you need to build up the request and parse out the response is in the .java files created by wsimport. As can be seen, the final code does not have any variables for the URL,namespace or SOAPAction. These details are taken care of in the .java files.

Time to compile and run the file. Commands are:


java Client

The client instance should connect to the Siebel Webservice now :


This code runs a  Query and prints out the Service Request Status, RowId and Owner details.

That’s it !! This is all you need to have a java client invoking a Siebel Webservice.

Inbound ASI–Keeping it simple


What is the easiest way to setup a new inbound web service in Siebel ? Well, a lot depends on the actual requirement, the complexity of the schema, error handling features etc. If the requirement is really simple, I try to go for an Application Service Interface or ASI. And specially if the requirement calls for multiple operations at a single web service, then ASI is the way to go.

An Application Services Interface (ASI) is a release-independent interface published by Oracle that allows you to integrate Siebel applications with external applications. An ASI is a collection of related methods; each method contains input and output parameters. The methods and parameters are listed on the business service definition. Simple method parameters (such as a string or number) are defined directly in the service definition. Hierarchical method parameters are defined using integration objects

Lets assume that the requirement here is to expose a query operation as a web service. The end point would invoke a Siebel web service which would extract data in a schema. Simple query operation. Here is how to do it in an ASI.

Step 1 : Define your schema. Decide upon an already present Integration Object or design a new IO from scratch. Here I’m choosing a custom Service Request IO, with attachments as the child IC. Don’t forget to decide upon the user keys and status keys.



Step 2: Define the ASI business service. Create a new business service, and set the class as CSSEAIDataSyncService. Define a method for this BS as QueryPage. Here I have added one more method for InsertOrUpdate.



Define the arguments of the methods. There has to be at least one argument of type Integration Object. Mention the IO name you had chosen in Step1


Two Business Service User properties are required.


Instead of creating the BS, an existing ASI can be simply cloned, in which case you would only need to change the IO name.


Step 3: Expose the BS as an Inbound web service.  Compile the IO and BS. On Siebel 8, simply right click the BS and choose deploy as web service. Or you could setup the service yourself.

In the application, go to Sitemap > Administration – Webservices > Inbound Webservice.


In service name, give any name and set the namespace. The namespace can be taken from the IO userproperties.

In Service Port, choose the newly created BS. Set the binding and transport values. Here I have chosen SOAP_DOC_LITERAL and HTTP Transport

In the Operations applet, the methods of the custom BS will be available. Set them up, and clear the cache.

That’s it, your done !!  You can generate the WSDL, and this can be consumed by the end point. The end system will get to see the various operations exposed under the service.

Here is how the WSDL looks when consumed in XML Spy:


And on choosing QueryPage method, XML Spy will generate this SOAP Request.


Regarding the different methods that can be exposed, there are six to choose from. And if needed, you can also provide datamappers for the request or response.

ASIs implement error handling in their own way and return SOAP fault codes back to the calling system.

Siebel ASIs are prebuilt and can be used immediately. ASIs provide a release-independent integration interface to the Siebel application, which remains unchanged with each upgrade to a new release. This is one of those few areas in Siebel where there is an upgrade-proof guarantee from Siebel/Oracle.
