bad file descriptor of tomcat

[koeicjm]

My servlet have code like this

BufferedReader in = new BufferedReader( new FileReader( objIDpath ) );
ref = in.readLine();

it seems when I call the servlet many times , the tomcat will get a "bad file descriptor" error , but if I add the
in.close();
it will run fine. must I close it ? and how can I set the tomcat to avoid it?

You should close input/output streams when you are finished with them.
