| | | EJB Handle | EJB Handle 2004-04-07 - By George Maggessy
Back
Hi Gurus,
I have a business delegate, that is also a singleton, that
caches an EJB Handle instance. I don?t why but my initial
lookups fail and after a pair of trials my application
starts to work well and it doesn't fail anymore . Could
anybody help me out with this problem? I'm working with a
clustered application and all of my EJBs have an initial
pool size of 5.
Thanks in advance,
George
