What steps will reproduce the problem? 1. I built index when parsing the "TheFirstOne.txt" 2. And use the index to search the content of "TheFirstOne.txt" 3. I test all things in search.jsp using google plugin for eclipse. What is the expected output? What do you see instead? The error is shown as below.

More problems:
And when I deploy my code to googe app engine. I run it. It gives me the errors as below:

This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application.

Hello for the problem java.lang.NoClassDefFoundError: sun.misc.Unsafe there is wiki page that explains cause and solution named deploy issue ram usage estimator .
Then your problem with the org.apache.lucene.store.LockObtainFailedException is probably related to the first one so first resolve that to see if this is automatically resolved, if not so it is related to an inconsistent state of your indexing directory stored into bigtable. No worry! Just go into Google AppEngine administration -> Datastore viewer, select GaeLock entity and delete all the entities, by doing that you will unlock every Lucene index that was locked for any reason.
Thank you for using LAE!

Hi~~ I have solved the org.apache.luncen.store.LockObtainFailedException according to your suggestion. I really appreciate it!!!~~
But I got another problem when I tried to build index for anthor txt (about 60MB). I am wondering is this problem also related to index? The problem is shown as below.

Yes, there is a problem in the index, go into Datastore Viewer and delete all the entry for all index related entities LuceneIndex, Segment and SegmentHunk.

Can you post the edu.ualr.oysterweb.CreateIndex class? Are you indexing <null> values?

I've tried your class into my test suite with TheFirstOne.txt as input and no error occurs.
Your class print this:
Total Clusters are: 586
Total Records are:1000
Check your war to see if there are multiple Lucene versions into WEB-INF/lib.
If you don't resolve the problem feel free to send me all your source code as zip so I can check and resolve your troubles in a shorter time.

Actually it works well when I run it in google plugin of eclipse. But the error happened when run it after deploy into google app engine server. The attachment is the source code.
Thanks for your time and help a lot a lot.

Last night I've investigated the trouble, probably there is a problem related to TextField.TYPE_STORED, try to replace it with new instances of FieldType created by a method like below:
private static FieldType newType() {
FieldType newType = new FieldType();
newType.setIndexed(true);
newType.setStored(true);
newType.setTokenized(true);
return newType;
}

Starting from LAE examples I've integrated your project and everything works, zip attached.
NB: change "gae.application.name" and "gae.serverId" properties in the pom.xml to deploy the application into your appengine server, more details here.
