You should note that the example uses WASP, not Apache SOAP.

Hi Elise,
please go through the document and try if it is of any help to u.

Code Examples
Now we'll show a few Web services interoperability examples. We will use a
simple banking application that is capable of keeping track of customers,
accounts, and account balances. We will also use the MS .NET weather service
that is listed on the XMethods site as a real-life example of Internet Web
service access, so you'll need to be connected to the Internet while running
this demo.
NOTE: If you haven't already downloaded the software used to create the
tutorial examples, please refer to the installation chapter in Part One.
You'll also need to download the demo sources. We assume that you've
unpacked this archive into the c:\wasp_demo directory. All Java sources
mentioned in the tutorial examples can be found in the src subdirectory of
the unpacked demo sources archive. They all reside in the com.systinet.demos
package. Similarly all scripts used in the demo are located in the bin
subdirectory. You don't need to download and use the software to understand
these articles, but we strongly recommend it.
Accessing a Microsoft .NET service from Java
We'll start with the Java client/.NET service example. As we mentioned
earlier, we will access the weather service listed on the XMethods site.
Click on the link and try the service online using the MS .NET invocation
framework. Next look at the WSDL document for this service. You'll notice
that it defines three bindings (WeatherRetrieverSoap,
WeatherRetrieverHttpGet, and WeatherRetrieverHttpPost).
Now let's create a Java client for this service. Run the
run_weather_client.bat script that's located in the bin directory of the
demo sources archive. Please note that we're using a lookup method that
specifices the fully qualified service name and the WSDL port. This lookup
method allows us to specify that we want to use the SOAP binding.
lookup("http://www.vbws.com/services/weatherretriever.asmx?WSDL";,
new javax.wsdl.QName("http://tempuri.org/";,
"WeatherRetriever"), "WeatherRetrieverSoap", WeatherRetrieverSoap.class)
Calling a Java service from a Microsoft .NET client
The opposite scenario is pretty straightforward. First start the Web service
runtime with the startserver.bat command, and then compile and deploy our
simple Bank Web service by invoking the deploy.bat command. Now we're ready
to show three different MS SOAP clients accessing our service.
NOTE: You need to use MS IE 6.0 or higher to run this demo.
First we will run a MS JavaScript SOAP Client. Invoke the run_web_client.bat
script. Specify an SSN number (you can use 001-0001-01, 002-0002-02 or
003-0003-03), and click the Get Accounts button, which populates the
accounts combobox. Choose an account in the combobox and retrieve the
account balance by clicking the Get Balance button. Look at the JavaScript
code in src\msjsclient.html for further details. The code is very
self-explanatory.
NOTE: You'll need to download and install the MS SOAP Toolkit 2.0 in order
to successfully complete the next example. You'll also need MS Excel on your
machine.
Now let's see the same functionality accessed from Microsoft Excel (using
Visual Basic). Open the src\Bank.xls spreadsheet and use the same steps
described in the previous example to navigate the application. You can find
the SOAP client code in the Visual Basic Editor (Tools->Macro->Visual Basic
Editor) in the Sheet1 module.
NOTE: You'll need to download and install the MS .NET Framework SDK to run
the C# part of this example
The last example demonstrates how to access our Java Web service from a C#
client. Run the run_csharp.bat script to generate a C# static proxy from the
service WSDL and to compile and run the client application. This example is
going one step further than our previous examples in that it passes a
Transfer structure from C# to Java. The previous examples pass only simple
data types. Notice the simple XML Schema definition of the Transfer type (it
includes the Balance element):
<xsd:schema
targetNamespace="http://idoox.com/wasp/tools/java2wsdl/output/com/systinet/d
emos/bank/">
<xsd:complexType name="Transfer">
<xsd:sequence>
<xsd:element name="type" type="xsd:string"/>
<xsd:element name="accountNumberBeneficiary" type="xsd:string"/>
<xsd:element name="comment" type="xsd:string"/>
<xsd:element name="balance" type="ns0:Balance"/>
<xsd:element name="amount" type="xsd:double"/>
<xsd:element name="timestamp" type="xsd:dateTime"/>
<xsd:element name="accountNumber" type="xsd:string"/>
<xsd:element name="transferID" type="xsd:long"/>
<xsd:element name="commentBeneficiary" type="xsd:string"/>
</xsd:sequence>
</xsd:complexType>
<xsd:complexType name="Balance">
<xsd:sequence>
<xsd:element name="changed" type="xsd:dateTime"/>
<xsd:element name="transfer" type="ns0:Transfer"/>
<xsd:element name="comment" type="xsd:string"/>
<xsd:element name="balance" type="xsd:double"/>
<xsd:element name="accountNumber" type="xsd:string"/>
<xsd:element name="transferID" type="xsd:long"/>
</xsd:sequence>
</xsd:complexType>
</xsd:schema>
The .NET WSDL compiler will generate the appropriate structures in C#. See
the stub in the src/ms/JavaService.cs for more details. Run the Java client
by invoking the run_java_client.bat script, and you'll notice that it does
the same thing.
NOTE: Both clients share the same Web service, and both clients make
withdrawals from the same account. So if you run the demo multiple times,
you can easily get out of funds. Then you'll get the
TransferProcessingException that says something like 'Insufficient funds'.
One nice thing you'll notice is that C# is able to transparently rethrow the
exception with the same message on the client side. Restart the Web services
runtime using the startserver.bat to renew your funds.

Subject: java client for .NET : need SOAPMapping sample code
hi,
i had a code, in the past, to marshall a java object into SOAP before to
send it to a java webservice.
Now, my java client calls a .NET webservice.
and the way i connect to the .NET webservice is different (i don't use
Call() class, i do use URL() class, just because taht's the only code i know
to connectto a .NET webservice)
the problem is that my SOAP code doesn't fit any more
could you post me a sample code, with a connection to a .NETwebservice and
a SOAPMapping ?
regards,
Elise
=======================================================
Old java code
Call call = new Call ();
call.setTargetObjectURI ("urn:liox:Project");
call.setMethodName ("getProject");
call.setEncodingStyleURI(encodingStyleURI);
SOAPMappingRegistry smr = new SOAPMappingRegistry();
ProjectSerializer beanSer = new ProjectSerializer();
StringDeserializer sd = new StringDeserializer ();
smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName("urn:Projects",
"Project"), Project.class, beanSer, beanSer);
smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName("", "return"),
Project.class, null, beanSer);
smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName("",
"ProjectCode"), null, null, sd);
smr.mapTypes(Constants.NS_URI_SOAP_ENC, new QName("",
"CompanyName"), null, null, sd);
call.setSOAPMappingRegistry(smr);
Response resp = call.invoke (url, "" );
=====================================================
New java code
byte[] request = marshall();
URL endpoint = new
URL("http://val1nt10/PCS_Integration/SynchronizeProfiles.asmx";);
URLConnection con = endpoint.openConnection ();
con.setDoInput (true);
con.setDoOutput (true);
con.setUseCaches (false);
con.setAllowUserInteraction(false);
con.setRequestProperty ("Content-Length",
Integer.toString (request.length));
con.setRequestProperty ("Content-Type", "text/xml;
charset=utf-8");
con.setRequestProperty ("SOAPAction",
"\"http://tempuri.org/WS_UpdateProfileAgency\"";);
OutputStream out = con.getOutputStream ();
//HERE SOAPMAPPING ???? HOW ??? it's not urn anymore true
???
out.write (request);
out.flush ();
out.close();
