BLOB - help

Question

Hi,
I am trying to flush & close the output stream after writing the object to BLOB. But both of these functions throws a IOException. This is what I do ..
BLOB blob = t_resultSet.getBLOB(1);
OutputStream blobOutput = blob.getBinaryOutputStream();
ObjectOutputStream oos = new ObjectOutputStream ( blobOutput );
blobOutput.flush();
blobOutput.close();
oos.flush();
oos.close();
On flush it says ..
java.io.IOException: ORA-00600: internal error code, arguments:
[ktsircinfo_num1
], [4290672316], [1022], [4093612], [], [], [], []
ORA-06512: at "SYS.DBMS_LOB", line 700
ORA-06512: at line 1
Moreover this problem is with read as wel ... meaning after you read and
then try a 'close' ..
Any thoughts ..?
Thx,

I am trying to load a file to an oracle blob using Java JDBC
I keep getting oracle error ORA-01002 fetch out of range
then i tried to lock the table with an exclusive lock
i get error
ORA-22920: row containing the LOB value is not locked
Please help
Statement stmt = con.createStatement();
stmt.execute("lock table lobtable in row exclusive mode");
File myfile = new File("trace.txt");
iStream = new FileInputStream(myfile);
rset = stmt.executeQuery("select testlob from lobtable where id = 1111"$
if(rset.next())
BLOB newBlob = (BLOB) ((OracleResultSet) rset).getBlob(1);
oStream = newBlob.getBinaryOutputStream();
int length = 0;
int pos = 0;
byte buf[] = new byte[1000];
while ((iStream != null) && (oStream != null) && ((length = iStream.read(buf$
System.out.println(
"Pos = " + Integer.toString(pos) + ". Length = " +
Integer.toString(length));
pos += length;
oStream.write(buf, pos, length);
iStream.close();
oStream.flush();
stmt.close();
oStream.close();
con.close();
