Re: [castor-dev] Problem Unmarshalling Soap-envelope using Castor

Ahh ... the story continues.

The Schema you are using, references another Schema <wsse:Security xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext"> which in turn imports other name spaces.

i.e.

<xsd:schema targetNamespace="http://schemas.xmlsoap.org/ws/2002/04/secext" xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns="http://schemas.xmlsoap.org/ws/2002/04/secext" xmlns:wsse="http://schemas.xmlsoap.org/ws/2002/04/secext" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:ds="http://www.w3.org/2000/09/xmldsig#" elementFormDefault="qualified" attributeFormDefault="unqualified" version="0.2">
<xsd:import namespace="http://www.w3.org/XML/1998/namespace" schemaLocation="http://www.w3.org/2001/xml.xsd"/>
<xsd:import namespace="http://www.w3.org/2000/09/xmldsig#" schemaLocation="http://www.w3.org/TR/xmldsig-core/xmldsig-core-schema.xsd"/>

This is a bit of a grey area for me so here's my best guess. :-)

You need to generate the code for each of these namespaces separately and in the castorbuilder.properties file setup the relationship between the namespace and the code base - see example below

Perhaps someone else who *uses* imports will help with the tutorial here ... :-)

# XML namespace mapping to Java packages
#
#org.exolab.castor.builder.nspackages=\
http://www.xyz.com/schemas/project=com.xyz.schemas.project,\
http://www.xyz.com/schemas/person=com.xyz.schemas.person

Thanks John.
I could overcome that error. I generated java files from WS-Security schema and Soap schema and my code was working fine. Then I generated java file using XML digital Signature schema and I started getting error given below.
Any help is appriciated. Thanks in advance.

Sharma,

I think your4 problem relates to the fact that the Elements and Types both resolve to the same class file. (Check this by cleaning the output running the generator without the -f flag) .

You can solve this quite easily by using the binding file to add a suffix to the names of the complex types. You need to pass a binding file similar to the one below to make this work ( add -binding-file to the source generator command line)

This will mean that the Element 'Header' will map to Header.java and ComplexType 'Header' will map to HeaderType.java

Subject: [castor-dev] Problem Unmarshalling Soap-envelope using Castor

Hi,
I am not able to compile the Java files, which I get after unmarshalling Soap-envelope xsd file using Castor.I am using this soap-envelope schema:
http://schemas.xmlsoap.org/soap/envelope/
When I create java files, these files have problem that the header, envelope and body file have circular referencing. It is like "Header extends Header". To solve this I tried removing type="tns:Envelope" from
<xs:element name="Envelope" type="tns:Envelope"/>
The number of compilation errors reduced but still it does not work. Another thing I noticed that the java files created do not have marshalling/unmarshalling methods.
Am I using the wrong file? I could do Marshalling/unmarshalling with a lot of other files, but i don't know why this is not working.
Any help is appriciated.
-Simmi.
