I followed the instuctions on the EJB3-Tutotial on the site
http://www.laliluna.de/download/firs...utorial-en.pdf
but I can't deploy the application right, as the error down shows.
I use mysql-ds.xml in the deploy-directory in JBOSS and mysql Server 4.1 and in
jboss and I placed the mysql Connector mysql-connector-java-5.0.6-bin.jar in
the directory
$JBOSS_HOME/server/default/deploy/lib as said in this tutorial. I don't
understand what the error-reason is. Has anybody an idea?Thanks.
My mysql-ds.xml -file looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<local-tx-datasource>
<jndi-name>ejb3ExampleDS</jndi-name>
<connection-url>jdbc:mysql://mysql-hostname:3306/examples</connection-url>
<driver-class>com.mysql.jdbc.Driver</driver-class>
<user-name>x</user-name>
y
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
<type-mapping>mySQL</type-mapping>
</local-tx-datasource>
