Hello to all.
I am having a problem with the use of UserTransaction to delimit one transaccion where several updates are made.
My environment is jBoss 3.0.0+Jetty and SQL2000 with MS JDBC driver.
The problem that I have is that when commit() the transaction the tables updated are blocked for reading,
and when I stop JBOSS, this does rollback of all the updates made by transaction.
It seems that commit() is not executed in fact.
Somebody can say to me if I am making something in erronea form?
Mi code is:
public void create(Object object) throws SaveException {
JdbcPersistenceManager pm = (JdbcPersistenceManager)this.getPersistenceManager();
Connection conn = pm.getConnectionProvider().getConnection();
UserTransaction tx = null;
try {
tx = (UserTransaction)ObjectLocator.getInstance().lookup("java:comp/UserTransaction");
tx.begin();
XmlHandler handler = new XmlHandler((String)object);
String whenSpecID = "";
String sql = this.getSQLforWhenSpec(handler);
Statement stInsert = conn.createStatement();
stInsert.executeUpdate(sql);
Statement stQuery = conn.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_READ_ONLY);
ResultSet rs = stQuery.executeQuery("SELECT @@identity whenSpecID");
if (rs.next()) {
whenSpecID = rs.getString("whenSpecID");
}
rs.close();
sql = this.getSQLforTriggers(handler, whenSpecID);
stInsert.executeUpdate(sql);
tx.commit();
} catch (Exception e) {
try {
if (tx != null) {
tx.rollback();
}
} catch (Exception se) {
throw new SaveException("TriggerSaveStrategy:create()",e);
}
throw new SaveException("TriggerSaveStrategy:create()",e);
} finally {
try {
if (conn != null) {
conn.close();
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
PS: if i use JDBC transaction (ie. conn.setAutocommit(false);....conn.commit()...conn.setAutocommit(true))
everything run fine.
