Hello,

I get lot of question being asked  as "where one has to use multi threading implementation environment"
i hope, it is not at the  receiving of large no of requests which would be not at   Servlet, as it will allow only single threading environment or synchronisation  

can one use  it in maintaining at the resource pooling in terms of caching environment...
Any more suggestion would be appreciated in terms of code....

thanks

Not quite sure what you're saying about servlets. They are by default multithreaded

Anywhere you need to replicate a task asynchronously.

thanks all.
Since in multithreaded servlets, all the user shares the same instance(if I understand correctly), the instance varibles will also be shared by all the clients. This is apparently a problem. The approach is handle this is to avoid using instance variable in multithreaded servlets? How that can be achieve ???

By using automatic (local) variables

Or use synchronization techniques (see above link)
