Incorporating WSIF Provider for Spring into BPEL

Question

I have extended the WSIF Java binding classes to invoke methods on Spring beans. This works fine when using WSIF (v2.0) on a standalone mode, but when I try to integrate this into the WSIF runtime that comes with Oracle BPEL, the Spring provider classes are not recognized (I get the error "unkown.port.type"). I added the Spring implementation of the WSIFProvider class to the META-INF/services/orabpel.apache.wsif.spi.WSIFProvider file in orabpel-thirdparty.jar [*], but this does not resolve the issue.
[*] I had to tweak the classes to make the package names consistent i.e. orabpel.apache.wsif.* instead of org.apache.wsif.*
I am using the earlier version of the BPEL Process Manager (v2.0 / 9i) and would like to know whether it is possible/worthwhile trying to get things to work in this version before going for the huge 10g download.
Any help will be immensely appreciated.

Cool,
I found this piece here on our internal network (it is for version 2.0), post that you will need to implement, extend the org.collaxa.thirdparty.apache classes (that are the modified apache ones)
quoted ...
Custom WSIF provider is a very good way for adding systems into BPEL PM. There are two tasks need to be done to plug in a WSIF provider after it is developed. First, the WSDL extension of that provider has to be registered to the WSDL reader. Second, the provider itself needs to be registered.
Register WSDL Extension
1.Create your WSDL extension object model following the java WSDL extension that’s include in the apache WSIF package. An extensionRegistry class, like JavaExtensionRegistry.java in the WSIF java package, is needed to register the WSDL extension.
2.Create a file [ORA_HOME]/system/classes/WSDLExtensions if it’s not already there. Add the name of the class in its own line into that file. This file will be picked up by the WSDL reader so your custom WSDL extension is recognized when the WSDL is parsed.
like
My.package.MyWSDLExtensionRegistry
Register WSIF Provider
1.Develop your custom WSIF provider following the example of any providers that come with the apache WSIF package.
2.Modify [ORA_HOME]/system/config/collaxa-config.xml file so the wsif-providers entry looks like:
<property id="wsif-providers">
<name>Custom WSIF providers for Oacle BPEL server</name>
<value>provider-class-name</value>

</property>
If you happen to migrate your code to 10.1.2.0.2 - and write something up I am happy to advertise it .. :-)
