Question

我将jbosscmp-jdbc.xml改成如下:
...
  <defaults>
    <datasource>pubs</datasource>
    <datasource-mapping>MS SQLSERVER</datasource-mapping>
  </defaults>
...启动时又出现如下错误,为何?
......
14:27:38,656 ERROR [EntityContainer] Starting failed jboss.j2ee:jndiName=Book,se

......

Answer 1

如果： 
<defaults>
<datasource>pubs</datasource>
<datasource-mapping>MS SQLSERVER</datasource-mapping>
</defaults>1 pubs ==> java:/pubs
2 在default/conf/standardjbosscmp-jdbc.xml中有一name为MS SQLSERVER的<type-mapping>项
