Subject [jira] Commented: (CXF-2083) XMLBeans - XmlBeansSchemaInitializer can't handle xs:import
Date Fri, 22 May 2009 21:26:45 GMT

    [ https://issues.apache.org/jira/browse/CXF-2083?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12712270#action_12712270
] 

Todd Michael commented on CXF-2083:
-----------------------------------

I can't speak to this problem directly, but I can say that the code in the XmlBeansSchemaInitializer.getSchema()
method (the method throwing your exception) is not currently capable of resolving external
XML schema references (i.e. http:// as opposed to relative locations in the local file system).
 The code is simply resolving all references locally using the following code:

InputStream ins = sts.getSourceAsStream(file);

If any of your XML schema <import> statements in any of your references schemas contain
URL/URI external references, this method will fail in exactly the same way as you have seen
in your attached stack trace.  In addition, even local file resources can fail to resolve
if you haven't correctly specified the relative file locations of each import in every schema
file you are deploying and managing locally.

I think this could be fixed fairly easily by simply making use of an XML entity resolver in
the getSchema() method and making sure that you deploy every required XML schema document
locally.  Please let me know if you have made any other progress on this issue, or if your
are still experiencing this problem.

>             Project: CXF
>          Issue Type: Bug
>    Affects Versions: 2.1.4
>         Environment: Java 1.5, Spring 2.5, CXF 2.1.4, Any OS.

> Background: 
> I have a Xfire project which I'm porting to CXF. Using the Document-First approach and
using XMLBeans. We have one xsd that imports other xsd's for each "domain". Every "domain"
xsd contains requests and responses which imports datatypes from underlaying schemas with
different namespaces.
> This works with JAXB (And Xfire with XMLBeans), but not with CXF and XMLBeans.
> I have simplified a test project.
> The structure is like this;
> PublishedFacade.xsd              -- imports sum.xsd
>          | ---- sum.xsd                -- contains request and responses. Imports types.xsd.
>                      | ---- types.xsd  -- contains complextypes and simpletypes for XMLObject
validation

> There were a similar error using xs:include (https://issues.apache.org/jira/browse/CXF-1700),
but I can't use include as the wsdl will be different when the namespaces changes. My wsdl's
should not change.
