Btw, Guillaume have written an excellent blog[1] to explain why weneed OSGiLocator and how it works for SPI mechanism in OSGi container.

Willem,

That explains it. I did look through the code and noticed the service
locator but couldn't understand how it was used....
Thanks for your help Willem. I posted on the servicemix list torelieve youa bit since this problem should belong to Servicemix and not Camel(where I
originally posted). But of course, you were here as well :-)

Hi Bengt,

I checked the code of servicemix jsr303 bundle, it just include the
servicemix locator and doesn't use the service locator to find theprovider
for you.

That explain why you get the below exception.
javax.validation.ValidationException: Unable to find a defaultprovider
I will try to do a quick fix today.

I'm using the servicemix packaging of hibernate-validator andjsr303:
*<dependency>*
*<groupId>org.apache.servicemix.specs</groupId>*
*<artifactId>org.apache.servicemix.specs.jsr303-api-1.0.0</artifactId>
*
*<version>1.5.0</version>*

*
<artifactId>org.apache.servicemix.bundles.hibernate-validator</artifactId>*
*<version>4.1.0.Final_1</version>*
*</dependency>*
I use the validator "manually" (not automatically via JPA) asfollows:
*
*
*public static Set<ConstraintViolation<?>> violations(ObjecttheObject,
Class<?>... theGroups)*
*      throws ConstraintViolationException {*

*    /**

*     * Perform bean validation*

*     */*
* ValidatorFactory factory =Validation.buildDefaultValidatorFactory();
// Throws exception*
*    Validator validator = factory.getValidator();*

*    return (Set) validator.validate(theObject, theGroups);*

*  }*


The line that creates the ValidatorFactory throws an exception when
called

When I run the same code outside of OSGi everything works. What amI doing
wrong?

The test above used Pax-Exam with Felix 3.0.2 but it doesn't seem to
matter
what OSGi container I use. I've tried different versions of FelixandEquinox but I get the same exception. I suspect I'm doingsomething wrong
but I cannot see what. Can someone help me out?
