I do have multiple values that need to be supported so the latter of
above is what I am using.

OK so my code now looks like this:
List<String> postalAddresses = ...
for (String postalAddressStr : postalAddresses) {
MessageBodyReader r =
providers.getMessageBodyReader(PostalAddressType.class,
PostalAddressType.class, new Annotation[1],
MediaType.APPLICATION_JSON_TYPE);
PostalAddressType postalAddress = (PostalAddressType)
r.readFrom(PostalAddressType.class, PostalAddressType.class, new
Annotation[1], MediaType.APPLICATION_JSON_TYPE,
new InBoundHeaders(),
new ByteArrayInputStream(postalAddressStr.getBytes()));
org.getPostalAddress().add(postalAddress);
}
I am now getting following exception:
java.lang.UnsupportedOperationException: Not supported yet.
at
com.sun.jersey.json.impl.JSONUnmarshaller.unmarshal(JSONUnmarshaller.java:175)
at
com.sun.jersey.json.impl.provider.entity.JSONRootElementProvider.readFrom(JSONRootElementProvider.java:119)
at
com.sun.jersey.core.provider.jaxb.AbstractRootElementProvider.readFrom(AbstractRootElementProvider.java:97)
Again I suspect I have the first and/or second params to
providers.getMessageBodyReader and r.readFrom set incorrectly because I
do not understand what is expected there.
Perhaps explaining what is expected there would help prevent ongoing
confusion in my mind.
I am very grateful for your help. Thank you.
