FileNotFoundException segments
Hi All
can someone please help me on the error in my web application...
I am using tomcat , the path for index dir is obtained from jsp page using application.getRealPath("/")+"download/compName"
I want to index when the file gets uploaded.
I am getting this error...

Ok, your directory exists.
if ((indexFile = new File(indexDir)).exists() && indexFile.isDirectory())
{
exists = false;
System.out.println("Index does not exist");
}
now is exists == false
at this point:
writer = new IndexWriter(indexFile, new StandardAnalyzer(), exists);
exists is still false. That means that your are trying to update an existing index. but there is no index inside your index. I think exists must be true so that a new index is created inside your directory!?
change the exists from false to true and everything should work fine ...

This is a new directory, created just before this step.
I am uploading files to this directory. The file is getting uploaded fine.
Any ideas?

probably the dir exists, but the index inside the dir is broken or not
complete and you are trying to use it instead of creating a new one?!
