Sergey, I think I confused you. The comment about the fields listed in the "fl" parameter has nothing to do with the SolrJ calls not working.
For SolrJ calls not working my suggestion is to look at the logs and compare the GetMethod call with the SolrJ call. Paste them if you want more people to look at them.
