http post with bpel

I am not sure if this forum is the right forum for my question but I post anyway to see if anyone can help
me. I have created a very simple bpel using http post; all it does is to copy the input to the output.
The output from my bpel looks like this:
<myContact xmlns="">
<ns0:LastName xmlns:ns0="" />
<ns0:FirstName xmlns:ns0="" />
<ns0:EmailAddress xmlns:ns0="">
<ns0 fficeAddress xmlns:ns0="" />

My question is why the EmailAddress element contains all my input data. I should expect the lastname element
has 'aa', the firstname element has 'bb', the emailAddress has 'cc' and the officeAddress has 'dd'.

Can someone please tell me what I do wrong in here.


Here's my html page to call the bpel process:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<form action="http://localhost:18182/XmlPostServiceService/XmlPostServicePort/submit" method="POST">
Last Name: <input type="text" name="LastName" value="" size="10" />
First Name: <input type="text" name="FirstName" value="" size="10" />
Email Address: <input type="text" name="EmailAddress" value="" size="10" />
Office Address: <input type="text" name="OfficeAddress" value="" size="10" />
<input type="submit" value="post" />


Here is the xsd file:
<?xml version="1.0" encoding="UTF-8"?>

<xsd:schema xmlns:xsd=""
<xsd:complexType name="MyContact">
<xsd:element name="LastName" nillable="true" type="xsd:string"/>
<xsd:element name="FirstName" nillable="true" type="xsd:string"/>

<xsd:element name="OfficeAddress" nillable="true" type="xsd:string"/>
<xsd:element name="myContact" nillable="true" type="tns:MyContact"/>

Here is my bpel file:
<?xml version="1.0" encoding="UTF-8"?>

In your WSDL you specify http:urlEncoded for the input of the operation.
So it is expecting to find the data as part of the query string in the URI, i.e.:

However the browser HTML form will make this type of an HTTP request:

According to the WSDL specification HTTP GET & POST Binding examples you need to specify <mime:content type="application/x-www-form-urlencoded" /> in your input binding:

I tried your way and I got this error:
Error: A <http:binding> element's input requires a <http:urlEncoded> or <http:urlReplacement> element.

BTW, thank you so much for your reply.

So that would mean that your tool really only supports HTTP GET bindings. That with http:urlEncoded and "method=GET" in the form should get you running.

... though as far as I recall BPEL systems usually use SOAP bindings for new components - not HTTP bindings. Non-SOAP bindings tend to be used for connectivity with existing systems.
