Java Mapping to Digital Signature (web service scenarios)

Question

Hi All,
I'm working with Web Service Scenarios and I have a problem.
The Web Service has a Schema for validation data and I send data to method of WS, example:
Web Service Description
<SendData xmlns="http://www.sdn.com/schema.xsd">
   <InputXML>string</InputXML>
</SendData>
For send data to "InputXML" is obligatory digital signature in Java.
I created a Java Mapping where get message of schema xsd, clear prefixes of tag and convert all schema to string.
Now Web Service response a error, because string is not contain "<" ">" just contain asc & lt; & gt;
Ex:
& lt;CodigoMunicipio& gt;2927408& lt;/CodigoMunicipio& gt;
In Debug Java Mapping in statement:
before
<CodigoMunicipio>2927408</CodigoMunicipio>;
rootelement.appendChild(element);
After
& lt;CodigoMunicipio& gt;2927408& lt;/CodigoMunicipio& gt;
And If use a rotine to convert it, in sxi_monitor generate a exception because not understand string field.
Can you help me?
Regards,
Bruno

Hi Bruno,
there are two ways to nest a xml document into another xml document.
The first one is escaping the XML, just like you did:
<document_one>
<input_xml>
&gt;document_two&lt;&gt;tag_a&lt;value&gt/tag_a&lt;&gt;/document_two&lt;
</input_xml>
</document_one>

The other is using the CDATA tag.
<document_one>
<input_xml>
<![CDATA[<document_two><tag_a>value</tag_a></document_two>]]>
</input_xml>
</document_one>

Then, if your webservice expects to receive a XML document inside the InputXML tag, probably it will be able to handle one of these techniques.
