This sounds fishy... why are you using Solr if you are only indexing one
field and it is the ID field?! That sounds like a particularly lame use of
Solr.
Declare the field as a "string" field and then Solr won't break it up into
tokens (other than special characters like slash.)
Or just set the defType="term" parameter. And the term query parser requires
the "f" parameter to be set to the field (maybe that was your NPE). You can
set those parameters in the "defaults" section of the request handler.
Or, you can you the real-time get handler, /get, which works fine for simple
retrieval by ID (or even a list of IDs).

Well, i couldnt get it work but maybe thats because im not a solr expert.
What im trying to do is:
I have an index with only one indexed field. This field is an id so I don't
want the standard queryparser to try to break it up in tokens. On the client
side I use solrj like this:
SolrQuery solrQuery = new SolrQuery().setQuery("<id>"); QueryResponse
queryResponse = getSolrServer().query(solrQuery);
I'd like to configure the TermQParserPlugin on the server side to minimize
my queries.

How are you using the term query parser? The term query parser requires a
field to be specified.
I use it this way:
q=*:*&fq={!term f=category}electronics
The "term" query parser would never make sense as a defType query parser, I
don't think (you have to set the field through local params).
