ejb3.0数据源配置文件mysql-ds.xml oracle-ds.xml persistence.xml sqlserver-ds.xml

ejb3.0数据源配置文件，直接COPY后将数据库名、用户名、密码改成你自己的，就能使用了。具体如下：

mysql-ds.xml ：

   Here are a couple of the possible OCI configurations.

   or
<connection-url>jdbc:oracle:oci:@(description=(address=(host=youroraclehost)(protocol=tcp)(port=1521))(connect_data=(SERVICE_NAME=yourservicename)))</connection-url>

   Clearly, its better to have TNS set up properly.
