using IndexRunner class  sucessfuly.

  When i try to access the webapplication using - 
http://localhost:8080/weblucene/search?dir=blog&query=query

  i'm getting a blank page , with the following error in the console .

  Caught error: java.io.IOException: D:\home\weblucene\webapp\WEB-INF\var\blog\index 
not a directory
  java.io.IOException: D:\home\weblucene\webapp\WEB-INF\var\blog\index not a directory
