You can use IndexWriter.unlock(Directory) to forcefully unlock the
index; just be certain the old IndexWriter really is gone before doing
that.
Or, if you have an IndexWriter still open, you could try
IndexWriter.rollback(), which discards all changes and closes the
IndexWriter. Or perhaps IndexWriter.deleteAll followed by commit.
When you get LockObtainFailedException it means your lock file is
still present and "locked"; what Directory and LockFactory are you
using?

Hi Mike,
Thanks for Your Reply.
Actually My question is wrong.
I have a large Index with a open IndexWriter.some one unknowlingly deleted
some files in the index and corrupted the index.
Once i get IndexCorruptedException,I will delete the entire Index Folder
and close my indexwriter also and Restart indexing process again.
In that time,I am Still Getting LockObtainedFailedException.
I am running this in a android device.
When i reboot the device,Indexing happens properly but without rebooting
iam getting LockObtainedFailedException.
Please kindly help me
