instead of this error, i can add, search data but when i m select user and update his information i have this error . I dont no realy where i can close the lock or doing something to resolve this problem to don t have it in the future.
a solution is to stop tomcat, remove lucene lock file and restart tomcat and all works fine but i cant stop/start tomcat all the time i would like to solve this problem in java.

if someone can help me :)

thanks by advance ;)
