I have tried to modify standalone.xml with <datasources>     <datasource jndi-name="java:jboss/datasources/Betreuung" pool-name="Betreuung">         <connection-url>jdbc:mysql://localhost:3306/Betreuung</connection-url>         <driver>com.mysql</driver>         <transaction-isolation>TRANSACTION_READ_COMMITTED</transaction-isolation>         <pool>             <min-pool-size>10</min-pool-size>             <max-pool-size>100</max-pool-size>             <prefill>true</prefill>         </pool>         <security>             <user-name>test</user-name>             <password>test</password>         </security>         <statement>             <prepared-statement-cache-size>32</prepared-statement-cache-size>             <share-prepared-statements/>         </statement>     </datasource>     <drivers>         <driver name="com.mysql" module="com.mysql">             <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class>         </driver>     </drivers> However each time I deploy my application or restart the server those changes are lost and the original standalone.xml is back. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/728869#728869] Start a new discussion in JBoss AS 7 Development at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
