Hi,
I am currently developing an EDIFACT extension for Camel, that parses
EDIFACT header information and provides them for further routing.
It contributes DataFormat, TypeConverter and an extension to the Camel
SimpleLanguage.
All works very nice and seamless (junit tests) unless it is used in an
OSGi environment.
To be able to use the SimpleLanguage extension in Spring configured
routes like in this example:
<camelContext xmlns="http://camel.apache.org/schema/spring/version-edifact";>
<route>
<from uri="file:e:/temp/file-io/file-in" />
<choice>
<when>
<edifact>
${ediPath(UNH/S009/D0065)} == 'DESADV'
</edifact>
<to uri="file:e:/temp/file-io/file-out/desadv" />
</when>
<otherwise>
<to uri="file:e:/temp/file-io/file-out/other" />
</otherwise>
</choice>
</route>
</camelContext>
I extended org.apache.camel.spring.handler.CamelNamespaceHandler.
My XSD includes the Camel XSD and consists furthermore of just one
element declaration:
<element name="edifact" type="camel:simpleExpression"
substitutionGroup="camel:simple"/>
My NamespaceHandler just overrides Set<Class>
CamelNamespaceHandler.getJaxbPackages() to add my JAXB package.
The JAXBContext is created with the ClassLoader of my
NamespaceHandler.class, any other ClassLoader like the ClassLoader of
CamelNamespaceHandler.class would not be able to access my
classes/resources.
The ClassLoader of my NamespaceHandler.class cannot access classes and
resources of Camel unless they are imported in the OSGi manifest
instructions.
But the package org.apache.camel.core.xml is not exported and required
to create the JAXBContex.
This is the point where i stuck now.
Suggestions?
Thanks,
Stefan
P.S. Camel is genious
