Handling Special characters in OSB

Question

Hi All,
We are using OSB with weblogic 11g in our Project. We found a strange behavior while fetching the data from DB using DB adapter.
For few records in DB, we are having & and few other special characters. While fetching the data:
•     If the content length is greater than “38” for a particular field which contains special characters, we are able to process it successfully (Data Comes as “&” for “&” in XML from DB)
•     If content length is less than “38”, “&” appears same without “amp;”
Please let me know if anyone have faced a similar issue. We would like to have "&" or "&", Only one and not both irrespective of the content length.
Any Clue would be of great help.
Regards

Thanks for your reply vlad.
When i mean OSB, it is ALSB which was aquired by oracle and named as OSB.
We have two records in Data base with '&'. when we picked both the records using DB adapter, one records is coming with "&" and other with "&".
To identify the issue in more detail, we tried to increase the length of the record by adding some extra normal characters and tested thoroughtly. At one point exactly when the length is >= 38, we found the records coming with "&". Similar behavior was observed in differnt DB's.
Sample Data:
"Asia Pac|China & Hong Kong|3J|Other Indochina| "
"Asia Pac|China & Hong Kong|CN|China| "
Not sure if this requires any weblogic level configurations/ or any other adapter level configurations so that data comes with "&"
We have defined the field in DB as Varchar2 (2000) and Please find below DB schema:
<?xml version = '1.0' encoding = 'UTF-8'?>
