XMLBeans build aborted for project ...project was missing Java nature.

Question

I always get this project level error in an OSB Project in Workshop whenever I add XMLSchema resources to the project and try to create XQuery Transformation resources. The project is then unusable and may not be deployed to OSB. I have tried adding the Apache XMLBeans and Java 6.0 facets, but that does not eliminate the problem. I can delete the project, create a new project, and copy all of the files from the old project to the new project but, as soon as I attempt to edit the XQuery Transformation, the error returns. The OSB Project in Workshop is, essentially, unusable if you want to add XQuery resources to your project. An OSB project without XQuery resources is just a Webservice, so using OSB isn't necessary. The only thing we have found that works it to edit the project in the OSB console.
The full error string in the Problems View is:
XMLBeans build aborted for project XXX because project was missing Java nature.
Any workarounds? Solutions? Configuration changes?

Answer 1

This is a strange error, because OSB projects do not use facets/natures/builders provided by Eclipse for any resources within the project. OSB has its own mechanism for validation on OSB Projects, so it's surprising to see any error messages from an XMLBeans builder relating to the Java nature.
Can you look at the OSB Project's properties and see if there are any facets/natures/builders/validators on the project?
The only builders should be:
- Faceted Project Validation Builder
- Validation
The only facets should be:
- AquaLogic Core Facet
- Oracle Service Bus
The following Validators should be disabled:
- WSDL Validator
- XML Schema Validator
