Subject Re: Axis2c Questions

If you are using any variables higher than request scope, you have to
create it in global pool. Apache is having its own memory pool
implementation to manage memory. I think, thats why it works with
simple axis server, but not with mod_axis2. Before creating the global
variable, you might have to switch to global pool and after creating,
you have to switch back to local pool.

Can you send your service code to find the exact problem?
