Datasource - JDBC - read in value of xml-type

Hi,

I'm trying to read a field of a table who has the value of a xml-type.

My driver and connection string are correctely filled in.
It is possible to read other fields (ex: select BALANCEOBJECTID from MOB_FU_CATALOG_B where BALANCEOBJECTID = 'BSCS24432443' --> BSCS24432443)

For the field (xmlchunk) with the xml-type, I use this statement:
select extract(XMLCHUNK,'/').getStringVal() from MOB_FU_CATALOG_B where BALANCEOBJECTID = 'BSCS24432443'

For the tool Oracle SQL+, it works and give me this result:

SQL> select extract(XMLCHUNK,'/').getStringVal() from MOB_FU_CATALOG_B where BALANCEOBJECTID = 'BSCS
24432443';

EXTRACT(XMLCHUNK,'/').GETSTRINGVAL()

When I run the datasource, it gives me a blanco value.
The soapUI-log tells me that he got 1 row (Wed Apr 15 14:50:57 CEST 2009:INFO:Got 1 columns from resultset).

Can someone help me with this problem?

Benny
