RE: offtopic question
It seems that now the latest MySql version (v.3.23.39) supports transactions. I have just tested it and everything seems to work fine. Regards, Vilavanh -Message d'origine- De : Lorenz, Manfred [mailto:[EMAIL PROTECTED]] Envoyé : 12 juillet, 2001 11:43 À : '[EMAIL PROTECTED]' Objet : AW: offtopic question You're not right. In the documentation about mysql i found the following: By default, MySQL runs in autocommit mode. This means that as soon as you execute an update, MySQL will store the update on disk. If you are using transactions safe tables (like BDB, InnoDB, you can put MySQL into non-autocommit mode with the following command: SET AUTOCOMMIT=0 After this you must use COMMIT to store your changes to disk or ROLLBACK if you want to ignore the changes you have made since the beginning of your transaction. If you want to switch from AUTOCOMMIT mode for one series of statements, you can use the BEGIN or BEGIN WORK statement: BEGIN; SELECT @A:=SUM(salary) FROM table1 WHERE type=1; UPDATE table2 SET summmary=@A WHERE type=1; COMMIT; Note that if you are using non-transaction-safe tables, the changes will be stored at once, independent of the status of the autocommit mode. If you do a ROLLBACK when you have updated a non-transactional table you will get an error (ER_WARNING_NOT_COMPLETE_ROLLBACK) as a warning. All transactional safe tables will be restored but any non-transactional table will not change. If you are using BEGIN or SET AUTOCOMMIT=0, you should use the MySQL binary log for backups instead of the older update log. Transactions are stored in the binary log in one chunk, upon COMMIT, to ensure that transactions which are rolled back are not stored. See section 23.4 The Binary Log. There are some alternative table formats, with which you can have transactions with mysql nowadays.

I think that access and mysql doesn't support transactions or they do not support the isolation level that was requested by your application. ANSI SQL defines 4 isolation levels and if application wants to have let's say committed read isolation level and db doesn't support it or doens't support higher isolation levels (e.g. repeatable read or serializable) then they need to abort the transaction. Access is kind of one man db and it doesn't support transactions I think, but I'm not sure about MySQL, but what I can remember is that it doesn't support transactions.
offtopic question
Hi all, I am currently building a web application with Struts and I am facing the following problem. I am using the CachedRowSet class to retrieve data from my database. Actually, I have no trouble when I perform a SELECT query. However, when I perform an UPDATE, DELETE or INSERT query, I get the following error message: transaction isolation levels not supported. This exception seems to be thrown only with MS Access and MySql databases. With Oracle, no exception is thrown and everything seems to work fine ... That let me suppose that both MS Access and MySql jdbc drivers do not support yet well the rowset package. Has anyone ever had such experience of this issue ? or could anyone give me some explanations ? Thanks in advance, Vilavanh Messien

If I understand, destroy() should be called when the servlet container (i.e Tomcat) is shutdown.

Thanks for your advice ! Nevertheless, I'd like to understand the mechanism used in the example. The load() method of DatabaseServlet is called during the init(). Thats'ok.

need some explanations
I analyzed the struts example in order to develop my own small application. Unfortunatelaty, I don't really understand how the user's information are saved in the "database.xml" file. The DatabaseServlet must write the information in the "database.xml" when the destroy() method is called. My question is how to make the destroy() method perform ? How can I do to pass some arguments to the DatabaseServlet ? Thanks Vilavanh
