[Biojava-l] blast parsing

[dkabic01]

hi
I am new to biojava having some difficulty parsing my output. I am using 
HT-BLast which is for  SGI computer systems . I am calling HT-BLAST program 
from my servlet program and it working fine. Problem arise when i add code for 
parsing the output. given below is the code for parsing the output and error 
message displayed my the TOMCAT server when servlet is executed.
code is :
InputStream is = new FileInputStream("/vol1/people/dinesh/htblast/test.out");
   try {
   XMLReader parser = (XMLReader) new BlastLikeSAXParser();
   ((BlastLikeSAXParser)parser).setModeLazy();
   SeqSimilarityAdapter adapter = new SeqSimilarityAdapter();
   parser.setContentHandler(adapter);
   List results = new ArrayList();
   SearchContentHandler builder = new BlastLikeSearchBuilder(results);

   adapter.setSearchContentHandler(builder);
   parser.parse(new InputSource(is));
   for (Iterator i = results.iterator(); i.hasNext(); ) {
   SeqSimilaritySearchResult result = (SeqSimilaritySearchResult)i.next();
   for (Iterator i2 = result.getHits().iterator(); i2.hasNext(); ) {
   SeqSimilaritySearchHit hit = (SeqSimilaritySearchHit)i2.next();

   out.println("sequence:\t"+hit.getSequenceID());
   out.println(" bits:\t"+hit.getScore());
   out.println(" e:\t"+hit.getEValue());
   }
   }
  }catch (SAXException ex) {
   ex.printStackTrace();
    }

and error messages is:



type Exception report

description The server encountered an internal error (Internal Server Error) 
that prevented it from fulfilling this request.
