5 sample questions about Single Thread Model (Cx 310 083)
0 likes818 views
The document contains 5 sample questions about implementing the single thread model in servlets and JSPs. The single thread model ensures that only one request is processed at a time by a servlet or JSP, making instance variables thread-safe. To make a servlet single threaded, implement the SingleThreadModel interface or add a configuration in web.xml. For JSPs and tag files, use page directives like <%@ page threadSafe="true" %>.
