Hi,
I am using cxf-bundle-jaxrs-2.2.
I tried registering it using
<jaxrs:providers>
<bean id="intArrayProvider"
class="com.mycompany.services.rest.util.ArrayParamHandler"/>
</jaxrs:providers>
To make it work, I changed the method getAddressById () to take String
instead of Int[], and inside the method I am using ArrayParamHandler to
convert it to Int[] (using fromString(ids))
public AddressDetailCollection getAddressById(@PathParam ("addressIds")
String ids)
