Indeed I find it hard to understand why the JAX-RS spec doesn't standardize a support for this (I've just created https://java.net/jira/browse/JAX_RS_SPEC-413 to address this).

However it is nevertheless possible to support multi-part forms in an implementation independent fashion. Either you write your own MessageBodyReader for MultiPart form or you use a library like Apache Clerezza jaxrs.utils which provide a MultiPartBody object which respective MessageBodyReader. This library has no implementation specification dependency so your application will run on any jax-rs implementation.

For an example on how Clerezza jaxrs.utils is used see line 105 in http://svn.apache.org/viewvc/stanbol/trunk/development/archetypes/stateless-webmodule/src/main/resources/archetype-resources/src/main/java/MultiEnhancer.java?revision=1465777&view=markup. If you're not using OSGi (with white-board registration of resources) you will have to add to org.apache.clerezza.jaxrs.utils.form.MultiPartFormMessageBodyReader to your Application.
