Hi,
I am not very clear on understanding the difference between RPC/Literal vs Document/Literal (Wrapped).

II am using Top Down approach by writing the wsdl first and then generating the java code using wsdl2java utility provided by cxf.

When i published the web service using Document/literal (wrapped) the soap message looks like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:unw="http://www.example.org/Unwrapped/">
<soapenv:Header/>
<soapenv:Body>
<unw:add>
<part1>?</part1>
<part2>?</part2>
</unw:add>
</soapenv:Body>
</soapenv:Envelope>

where add is the name of the part inside the message tag in the wsdl. As per documentation the part name MUST be same as the Method name in wrapped Document/Literal

But when I use the RPC/Literal the soap message looks like this:

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:rpc="http://www.example.org/rpcLiteral/">
<soapenv:Header/>
<soapenv:Body>
<rpc:add>
<parameters>?</parameters>
</rpc:add>
</soapenv:Body>
</soapenv:Envelope>

where add is the method name.

I am not sure what exactly is the difference between them. Both RPC/Literal and Document/Literal (wrapped) has the Method name as the first child of the Body ( As per documentation the part name MUST be same as the Method name in wrapped Document/Literal). As I am able to create complexTypes in the <types><schema..> section for both RPC and Document (wrapped), so my question is what exactly is the diffence between them?

regards,
khan
