Problems with indexing files from my hard disk

Question

Hi everybody,
I'm a newbie to oracle and i'm trying to index files from my hard disk with oracle text. After i created a simple text file (path: 'c:\tmp\test.txt') and filled it with a short text, i executed the following lines without an error message:
grant connect, resource, ctxapp to myuser;
create table myuser.testtab(id number primary key, text BFILE);
create or replace directory test_dir as 'c:\tmp';
grant read on directory test_dir to myuser;
insert into myuser.testtab (id, text) values (1, BFILENAME('test_dir','test.txt'));
create index myuser.idx_test on myuser.testtab(text) indextype is ctxsys.context;
the record in the table testtab is stored, but the index table is empty. After i tried to get information about the bfile with java i got an SQLException with the Error-Code ORA-22285 after executing the following lines:
BFILE file = null;
try{
rset = stmt.executeQuery("select text from testtab where id = 1");
if (rset.next()) {
file = ((OracleResultSet) rset).getBFILE(1);
System.out.println("Result from fileExists: " + file.fileExists()); //This is the line where the exception is thrown
} catch (Exception e){
e.printStackTrace();
I would be obliged for any information to this problem.
Thanks in advance,
Chris J.
PS: i'm using Oracle 11.2g on Windows 7

I got your problem. Drop all the directory,table and index. Log in as "myuser" and do all the things. See the demo below. Don't use myuser.object name When executing the commands from "myuser".
