Hernan,

I got it working finally , both with the sticky session=0,1 , in non-sticky session , some time it fails...!

Any idea..?

(I have given my config details after my questions,ie, below..!)

Some questions:

a) Note: Once I build my EAR file , I deploy it on both the machines, so the Geronimo-web.xml is the same on both machines, I guess it has to be different w.r.t 'mcastBindAddress' - value for different instances..!

b) One more question I need to ask is : gbean name="FarmWarDeployer" , needs to be specified in the deployment plan , or is it optional…?

c) By the way , what is farming , is it used for deploying ur application on to the cluster members, if so , will it change the deployment plan at run time..?

(correct me if I am wrong..!)

As asked, here are my details (that I added to the existing stuff):

-------------Part of Httpd.conf file ------

LoadModule jk_module modules\mod_jk.so

Hi Santosh,

can you provide more details (what, how, when)

Can you forward a request from one HTTP to one Geronimo?

Cheers!

Hernan
