I writen an entity bean,it have a Long key field,a String field,a Timestamp
field...
In my session bean ,I create a entity in a interface function createBug,update
the String filed value and Timestamp field value in other function updateBug.
I found the String field value is error,I update the value to "a_yyb", but the
value in oracle database is not "a_yyb"!!!
Then I change the Timestamp field type to java.sql.Date ,I found String value
is correct.
It is a jboss bug? or oracle bug? or jdk bug?

debian-sarge,kernel:2.6.14.3
