Apache SOAP 2.2 Overview Page 17

Conclusion

Apache SOAP is a comprehensive implementation of SOAP. Nonetheless it moves away from the rules for referencing services by using its own description language (deployment descriptor). As regards interoperability, problems are recurrent, regardless of the implementation. This is caused by the lack of compliance with standards, both in terms of transport protocols and XML parsing. Another important issue is the status of the SOAP standard itself. It is in note status, therefore will move up to a recommendation. Evidently, as long as a standard is not definitive, some small interoperability problems will persist.
