Dear ladies and gentlemen, I intend to develop an J2EE-Application using Allaire's Applicationserver JRun. The basing Database should be MySql. Since MySql supports no transaction management, there is a problem to deploy Entity Enterprise Java Beans, because the applicationserver needs to set a transaction isolation level. Therefor it uses the Java-method setTransactionIsolationLevel(int level) of class org.gjt.mm.mysql.Connection But it returns a java.sql.SQLException with the message: java.sql.SQLException: Transaction Isolation Levels are not supported. I have installed MySQL 3.23 on a Solaris machine. I also heard of the add-on module Berkeley DB, that should make possible to use transactions with MySql. So I installed Berkeley DB Version 3.1.17 and tried to deploy and run my J2EE Enterprise Bean - without success. Nevertheless, is it possible to get work my Enterprise Java Entitybean with MySql? Thanks for any help. -- Raymond Schulz - Chief Developer Interway AG Gabelsbergerstr. 47, 80333 München T. 089/28788-0, F. -100 http://www.interway.net
