The Data Import Handler isn't pushing data into the /update request handler. However, Data Import Handler can be extended with transformers. Two such transformers are the TemplateTransformer and the ScriptTransformer. It may be possible to get a script function to load your custom Java code. You could also just write a StandfordNerTransformer.
