unknown-pk always return BigDecimal with Oracle

[tyang]

When i use the unknown-pk mechanism in Jboss 3.2.0 with Oracle 9i to generate primary keys, regardless how i configure it in jbosscmp-jdbc.xml, the primary key I got is always of type java.math.BigDecimal. To get around I have to transform it into java.lang.Integer type, which is really what I want. It looks to me that the unknown-pk-class, jdbc-type, or sql-type configurations are ignored by jboss. For unknown-pk-class, you can have java.lang.Long, java.lang.Object or whatever, jdbc-type can be NUMERIC, INTEGER or whatever, the same BigDecima is returned.

This problem applies to Oracle 8i also. Does anybody else have this problem? Do i miss something here, or it's sopposed to be working like this?

Here is the the relevent code and configs

ejb-jar.xml


<ejb-name>PKTest</ejb-name>
<local-home>com.ersus.test.PKTestLocalHome</local-home>
com.ersus.test.PKTestLocal
<ejb-class>com.ersus.test.PKTest</ejb-class>
<persistence-type>Container</persistence-type>
<prim-key-class>java.lang.Object</prim-key-class>
False
<cmp-version>2.x</cmp-version>
<abstract-schema-name>PKTest</abstract-schema-name>
<cmp-field>
<field-name>name</field-name>
</cmp-field>
<security-identity>
<use-caller-identity/>
</security-identity>


jbosscmp-jdbc.xml


<ejb-name>PKTest</ejb-name>
java:/ORACLEDS
<datasource-mapping>Oracle9i</datasource-mapping>
<create-table>false</create-table>
<remove-table>false</remove-table>
<read-only>false</read-only>
<table-name>PKTEST</table-name>
<cmp-field>
<field-name>name</field-name>
<column-name>NAME</column-name>
</cmp-field>
<unknown-pk>
<unknown-pk-class>java.lang.Integer</unknown-pk-class>
<field-name>id</field-name>
<column-name>ID</column-name>
<jdbc-type>INTEGER</jdbc-type>
<sql-type>NUMBER(10)</sql-type>
</unknown-pk>
<entity-command name="pk-sql">
SELECT PKTEST_SEQ.NEXTVAL FROM DUAL
</entity-command>



Java code:

try{
InitialContext ctx = getInitialContext();
Object obj = ctx.lookup("PKTestLocal");
PKTestLocalHome test_lh = (PKTestLocalHome)obj;
PKTestLocal test = test_lh.create("test name");
logger.info(test.getPrimaryKey().getClass().getName());
}catch(Exception e){
e.printStackTrace();
}
