Hello, Martin!
Thanks a lot for the advice. Do you know where I could get this
commons-transaction-1.1.1pre1.jar? I haven't been able to find it, decided
to try downloaded the 1.1 release, downloaded the
commons-transaction-1.1.jar and got the following error:
10 Jun 2005 20:24:18 - org.apache.slide.webdav.WebdavServlet - ERROR -
