hi,everyone! i used jboss 4.0.4 and j2ee-1_4-doc-tutorial_2. when i used mysql as database, there was a problem. the page show no data from the database when i log in Duke?s Bank. so the connection was wrong. fisrt, i move the mysql-connector-java-3.1.14-bin.jar to default lib. then built mysqldb-ds.xml in deploy. coded that <?xml version="1.0" encoding="UTF-8"?>
the server said 20:40:26,102 ERROR [MainDeployer] Could not initialise deployment: file:/D:/EE55 7ServerSide/ejb3/jboss/server/default/deploy/mysqldb-ds.xml org.jboss.deployment.DeploymentException: Could not parse dd; - nested throwable : (org.xml.sax.SAXParseException: The processing instruction target matching "[x X][mM][lL]" is not allowed.) i have checked the content. it seem ok.even though nothing in the mysqldb-ds.xml, the server still was wrong. i lost some moves??? help!!!thank you!!!!
