jbuilder9.0下定义如下的数据源：
<!--定义数据源-->
<data-sources>
<data-source>
<set-property value="false" property="autoCommit" />
<set-property value="Data for tradesystem" property="description" />
<set-property value="sun.jdbc.odbc.JdbcOdbcDriver" property="driverClass" />
<set-property value="5" property="maxCount" />
<set-property value="1" property="minCount" />
<set-property value="jdbc:odbc:localserver" property="url" />
<set-property value="sa" property="user" />
<set-property value="sa" property="password" />
</data-source>
</data-sources>
请问在程序中获得上面定义的数据源？？？？
