1. Re: Use MS-Access as EJB datasource
viz Jul 3, 2003 4:37 PM (in response to myoranges)There is an msaccess-ds.xml in the \docs\examples\jca directory - which would imply that it is supported?

pranav Jul 4, 2003 5:48 AM (in response to myoranges)Yes...it indeed is supported... I have tested it, and it works fine...

4. Re: Use MS-Access as EJB datasource
viz Jul 7, 2003 4:13 AM (in response to myoranges)Humm.... I did wonder why one might choose MS Access - not exactly the most robust, scalable datasource solution ;-)

5. Re: Use MS-Access as EJB datasource
myoranges Jul 8, 2003 1:37 PM (in response to myoranges)Does anyone a working example of standardjbosscmp-jdbc.xml with the addition of the mapping to MS-Access? I have added the following mapping but it gives me an error.

And this is the error:

I know the MS-Access is not very good db for web application but our client strongly requests to use it... Thank you for all your help! -
6. Re: Use MS-Access as EJB datasource
viz Jul 11, 2003 7:19 AM (in response to myoranges)You shouldn't need to touch the standardjbosscmp-jdbc.xml
Simply copy the msaccess-ds.xml to the /deploy folder then create a jbosscmp-jdbc.xml to use ms access. I've not tried this, but recently struggled with mySQL and this very issue.

7. Re: Use MS-Access as EJB datasource
viz Jul 11, 2003 7:21 AM (in response to myoranges)What I mean by 'I haven't tried this' is that I've not tried this with MS Access :-)
BTW the jbosscmp-jdbc.xml should be located in you META-INF directory.
