Preamble is omitted when supplying WSDL and external XSDs
---------------------------------------------------------

                 Key: JBWS-3345
                 URL: https://issues.jboss.org/browse/JBWS-3345
             Project: JBoss Web Services
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: jbossws-native
    Affects Versions:  jbossws-native-3.1.2
            Reporter: Kyle Lape

The XML preamble is omitted when serving external WSDL resources.  This can cause problem when specifying a non-default character set using the XML preamble.

For example, you access an external XSD:  {noformat}http://localhost:8080/testService/Service?wsdl&resource=external.xsd{noformat}

The file on the server starts like this:

{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema ...>
  ...
</xsd:schema>
{code}

But when it's served to a client, it starts like this:

{code:xml}
<xsd:schema ...>
  ...
</xsd:schema>
{code}
This affects the WSDL and any resources referenced by the WSDL.

Looking at the code, this is what happens when a request for a WSDL resource is received:
- The WSDL resource is read in from the file system.
- It is then parsed into a DOM tree.
- JBossWS then replaces references to external resources with appropriate URLs that can be reached using "?wsdl" URLs.
- The DOM tree is then marshaled to XML text.

In this process, the XML preamble is lost.
