If these are cmp2 beans with relationships between them it is possible that the beans don't actually get started until the second bean in the relationship is deployed. If so, adding depends on all beans in the relationship to your mbean should work, although it's a bit messy.
I don't have a good solution to starting ejbs in relationships, we've tried various things and none seem quite right yet. Let us know whether or not this is/fixes the problem thanks david jencks On 2002.08.21 16:28:19 -0400 Brian Macy wrote: > Ok...
