[jbossws-issues] [JBoss JIRA] Commented: (JBWS-3339) Preamble is omitted when supplying WSDL and external XSDs

[Marko Asplund (JIRA)]

    [ https://issues.jboss.org/browse/JBWS-3339?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12624484#comment-12624484 ] 

Marko Asplund commented on JBWS-3339:
-------------------------------------

if either utf-8 or utf-16 should be used, how does one specify which one is actually used?
i think the preamble is the standard way of specifying that.
or is is there another way of doing that?

> 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.
