Creating Top Down Web Service via Apache Axis2

This tutorial is meant to demonstrate the use of the newly introduced Axis2 Web Services tools in the Web Tools Platform Project using the WTP 2.0 drivers. Also this tutorial shows how to create a simple top-down Web service from a WSDL file and test that with the WSE (Web Service Explorer). The WSDL file in this scenario calculates the area of an rectangle and its the same WSDL that used in the Axis web services tutorials.

old ... but do the job

Creating Top Down Web Service via Apache Axis2

Consume C# DataSet from .Net webservice

Hi
you wish to consume DataSet from .NET webservices , anyway i could not find an easy way to do it , as you do it within c# code, you must deal with XML parsers.
any way, a very good explanation and description could be found here Web Services and DataSets.

In short .. it is most recommended to expose the results as array of objects ,when you want your Java consumer be happy.
.... i used axis 2 to generate webservice proxies .

good luck

How to consume WCF service from Java - step by step

Here is a step by step sample how to consume WCF service from java.

WCF in VS.NET (2008 in my case):
create a new project
file->new->project->web->wcf service application
leave the default settings as is , a new WCF service created by the wizard called Service1.svc.
press F5 -> make sure you can see the service page http://localhost:2813/Service1.svc and his wsdl file
http://localhost:2813/Service1.svc?wsdl.

to connect from java to WCF service we have to change the binding type from the default "wsHttpBinding" to "basicHttpBinding".
to do that , edit the Web.config file
change the end point to somthing like this :
<endpoint address="" binding="basicHttpBinding" bindingconfiguration="Binding1" contract="WcfService1.IService1"> </endpoint>

add the next binding section ( you can change it as you like)
<bindings>
<basicHttpBinding>
<binding name="Binding1"
hostNameComparisonMode="StrongWildcard"
receiveTimeout="00:10:00"
sendTimeout="00:10:00"
openTimeout="00:10:00"
closeTimeout="00:10:00"
maxReceivedMessageSize="65536"
maxBufferSize="65536"
maxBufferPoolSize="524288"
transferMode="Buffered"
messageEncoding="Text"
textEncoding="utf-8"
bypassProxyOnLocal="false"
useDefaultWebProxy="true" >
<security mode="None" />
</binding>
</basicHttpBinding>
</bindings>
press F5 -> make sure you can see the service page after the changes  http://localhost:2813/Service1.svc and his wsdl file http://localhost:2813/Service1.svc?wsdl

JAVA side:
open cmd  window
cd to your axis2/bin directory  , cd C:\Program Files\Apache Software Foundation\axis2-1.5.2\bin
create directory test in the bin folder , mkdir test.
run the next batch file from your bin directory
wsdl2java.bat -o test -uri http://localhost:2813/Service1.svc?wsdl
the above command should generate the java stub to connect to your wcf service.
Service1CallbackHandler.java and Service1Stub.java.

add those file into your java test program and create your test function.
public static void CallWCFService()
{
try {
Service1Stub srv1 = new Service1Stub();
srv1._getServiceClient().getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.CHUNKED,Boolean.FALSE);
Service1Stub.GetData data = new Service1Stub.GetData();
data.setValue(44);
Service1Stub.GetDataResponse reposne = srv1.getData(data);
System.out.println(reposne.getGetDataResult());
} catch (AxisFault e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

if you will remark the yellow line (enable the chunk), you will get the
org.apache.axis2.AxisFault: The input stream for an incoming message is null.
when i disabled the chunk , it works perfect.

i would like to say a special thanks to Yaron Naveh , that guide & helped me to get this works,Yaron have a very informative blog on this subject too, thanks Yaron !!!

From Microsoft article (http://msdn.microsoft.com/library/ee958158.aspx)

“For communication with the Java EE-based reservation application, a binding that uses standard SOAP on the wire is required. If the application and the platform it runs on support some or all of the WS-* specifications, the endpoint used by this client might choose WsHttpBinding. This would allow reliable, secure, and transactional communication between the two applications.
If this application and the platform it runs on support only standard SOAP matching the WS-I Basic Profile, however, the endpoint it uses to access the rental car reservation application would use BasicHttpBinding. If transport security is required, this binding could be configured to use HTTPS instead of plain HTTP.”
