Hi Kevin, Yes, I did go through that discussion. As the first step, I am trying for the stored procedure implementation. But definitely the bigger goal is the complete clean integration. Have created JIRAhttps://issues.apache.org/jira/browse/TUSCANY-876 for this specific item. We can link it to the wish list JIRA http://issues.apache.org/jira/browse/TUSCANY-864.
Will check with you for any specifics on DAS, as and when I come across any problems. Thank you. Amita On 10/18/06, Kevin Williams <[EMAIL PROTECTED] > wrote:
Hello Amita, A clean integration between RDB DAS and SCA is a very important and the DAS team is ready to help.
