SEQUENCE TABLE QUESTION

Question

For the sequencing processing, i tell TopLink to use Native Sequencing in my mapping file. When i generate it, TopLink write in the file :
<uses-native-sequencing>true</uses-native-sequencing>
<sequence-table>SEQUENCE</sequence-table>
<sequence-name-field>SEQ_NAME</sequence-name-field>
<sequence-counter-field>SEQ_COUNT</sequence-counter-field>
But my SEQUENCE TABLE name is USER_SEQUENCES (ORACLE SYSTEM TABLE) with SEQUENCE_NAME and LAST_NUMBER as fields.
I can not rename this table in "SEQUENCE" like TopLink want.
How can i do without modify the mapping file ?

Answer 1

I have the proof that TopLink use the sequence-table, sequence-name-field, sequence-counter-field when i use Native Sequencing. TopLink generates :
<uses-native-sequencing>true</uses-native-sequencing>
<sequence-preallocation-size>1</sequence-preallocation-size>
<sequence-table>SEQUENCE</sequence-table>
<sequence-name-field>SEQ_NAME</sequence-name-field>
<sequence-counter-field>SEQ_COUNT</sequence-counter-field>
SEQUENCE is not found when i commit a record -> error
If i modify the XML file with :
<uses-native-sequencing>true</uses-native-sequencing>
<sequence-preallocation-size>1</sequence-preallocation-size>
<sequence-table>USER_SEQUENCES</sequence-table>
<sequence-name-field>SEQUENCE_NAME</sequence-name-field>
<sequence-counter-field>LAST_NUMBER</sequence-counter-field>
USER_SEQUENCES exist, it works !!
Here is my code when i log to my server :
private static ServerSession launchServer() {
if (_server == null) {
String fileName =
Configuration.getInstance().getProperty(
"project.mapping_file");
if (new File(fileName).exists()) {
Project builderProject = XMLProjectReader.read (fileName);
_server = (ServerSession)   builderProject.createServerSession (1, 50);
_server.useExclusiveReadConnectionPool(1, 1);
_server.logMessages();
try {
_server.login();
} catch (DatabaseException e) {
} else {
throw new RuntimeException(
"Fichier " + fileName + " n'existe pas...");
} else {
throw new RuntimeException("M�thode static StarServerSession.launchServer() ex�cut�e deux fois...");
return _server;
My code to acquire a client session :
public void open() throws DBException {
try {
clientSession = DBServerSession.server.acquireClientSession();
} catch (DatabaseException e) {
throw new DBException(
DBException.DATABASE_EXCEPTION_ERROR_CODE,
e.getDatabaseErrorCode(),
e.getMessage());
}
