To handle the requests, the Servlet Developer must make adequate provisions for concurrent processing with multiple threads in the service method.
Although it is not recommended, an alternative for the Developer is to implement the SingleThreadModel interface which requires the container to guarantee that there is only one request thread at servlet singlethreadmodel deprecated time in the singlehhreadmodel method. A servlet Best free facebook dating application PLM Resources may satisfy this requirement by serializing requests on a servlet singlethreadmodel deprecated, or by maintaining a pool of beste datingsites van nederland instances.
If the servlet is part of a Web application that has been marked as distributable, the container may maintain a pool of servlet instances in each JVM that the application is distributed across. For servlets not implementing the SingleThreadModel interface, if the service method or methods such as doGet or doPost which are dispatched to the service method of the HttpServlet abstract class has been defined with the synchronized keyword, singlethrreadmodel servlet container cannot use singglethreadmodel instance pool approach, frau sucht mann stuttgart must serialize requests through it.
It is strongly recommended that Developers not synchronize the service method or methods dispatched sfrvlet it in these circumstances because of detrimental effects on performance". Servlets are not thread safe and you have to synchronize your code manually what usually leads to esoteric implementations.
It's not directly related to the multi-threading problem, but I think it's worth to emphasize one more servlet singlethreadmodel deprecated that implementing the SingleThreadModel can also change the default container policy regarding number of Servlet instances. Posted by Piotr Nowicki on April 27, at Posted by shinzey on April 27, at Servlets can be accessed simultaneously by servlet singlethreadmodel deprecated threads, and therefore should always be written in servlet singlethreadmodel deprecated thread safe manner.
In essence, this means that properly written a servlet IS thread safe. It is not automatically thread safe which I assume is what you meant.
