The HttpSession object could not be instantiated because the number of global sessions has reached the maximum. (J2EE application = aa....aa, context root = bb....bb, max global sessions = cc....cc)

aa....aa: J2EE application name
bb....bb: Context root name
cc....cc: Upper-limit value of the global session count
The HttpSession object could not be generated because the global session count has reached the upper-limit value.

Action

The number of global sessions of the database might be too less. Increase the upper-limit value of the global session count of the database as and when required.
