The following works fine:
/**
* @ojb.field jdbc-type="INTEGER"
*
conversion="org.apache.ojb.broker.accesslayer.conversions.Boolean2IntFieldCo
nversion"
*/
protected boolean deleted;
But, if you use:
@ojb.field jdbc-type="TINYINT"
Then, xdoclet does as it should:
<field-descriptor
name="deleted"
column="deleted"
jdbc-type="TINYINT"
conversion="org.apache.ojb.broker.accesslayer.conversions.Boolean2IntFieldCo
nversion"
>
And ojb dies (although i am kinda sympathetic as it is using Boolean2Int,
not Boolean2Tinyint!):
[PersistentField] ERROR: while set field:
