Hi Bengt,

I just created a JIRA[1] and submitted a patch which was tested withyour test case.


I also added a workaround comment on the JIRA[1], Please check it out.

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 to relieve you
a 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 the provider
for you.

That explain why you get the below exception.


  javax.validation.ValidationException: Unable to find a default provider

I will try to do a quick fix today.

I'm using the servicemix packaging of hibernate-validator and jsr303:

*<dependency>*
*<groupId>org.apache.servicemix.specs</groupId>*
*<artifactId>org.apache.servicemix.specs.jsr303-api-1.0.0</artifactId>
*
*<version>1.5.0</version>*
*</dependency>*
*
*
*<dependency>*
*<groupId>org.apache.servicemix.bundles</groupId>*
*

  <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) as follows:
*
*

  *public static Set<ConstraintViolation<?>>   violations(Object theObject,

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
from wihin OSGi:

When I run the same code outside of OSGi everything works. What am I 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 Felix and
Equinox but I get the same exception. I suspect I'm doing something wrong
but I cannot see what. Can someone help me out?
