singlethread model

[clyde melly]

if a servlet implements the singlethread model and suppose there are 10 requests,how many instances are created and how does the management for the request proceed.if the single thread model is not implemented then how many instances wud be created for the 10 requests as stated above.

*** SingleThreadedModel is depricated. Now a days nobody uses it ****
If a servlet implements single threaded model, then one instance of that servlet can serve only one request at a time. The number of instances created can be specified by the user in web.xml.

If the servlet does not implement single threaded model, then with single instance, 10 requests can be served.

so for 10 requests 10 instances ??? in which case implementing singlethreadedmodel?

[unni krishna]

friend, dont use singlethreaded model. if u implement single threaded model, then the number of requestes that can be served at a time is equal to the number of instances of the servlet that you create.

[clyde melly]

i get it but just wanted to know how does the request management happen with both approach in details

Funny how many of the same people who disparage SingleThreadModel are happy with EJBs Having said that, I would agree: don't use SingleThreadModel (or the JSP equivalent). Write threadsafe code. It's not that hard.
