Servlet:SPEC:269 | 1 | 6.1 | In Servlet 2.5, metadata-complete only affected the scanning of annotations at deployment time. The notion of web-fragments did not exist in servlet 2.5. However in servlet 3.0 and later, metadata-complete affects scanning of all annotations that specify deployment information and web-fragments at deployment time. The version of the descriptor MUST not affect which annotations you scan for in a web application. An implementation of a particular version of the specification MUST scan for all annotations supported in that configuration, unless metadata-complete is specified. | true |  | false | technology | active | true

Servlet:SPEC:280 | 3 | 6 | In situations where the servlet container cannot determine a valid file path for these methods, such as when the Web application is executed from an archive, on a remote file system not accessible locally, or in a database, these methods must return null. | true |  | false | technology | active | true
Servlet:SPEC:281 | 3 | 6 | Resources inside the META-INF/resources directory of JAR file must be considered only if the container has unpacked them from their containing JAR file when a call to getRealPath() is made, and in this case MUST return the unpacked location. | true |  | false | technology | active | true
Servlet:SPEC:282 | 3 | 7 | The ReadListener provides the following callback methods for non blocking IO - | true |  | false | technology | active | true
Servlet:SPEC:282.1 | 3 | 7 | ReadListener.onDataAvailable(). The onDataAvailable method is invoked on the ReadListener when data is available to read from the incoming request stream.

Servlet:SPEC:288 | 6 | 2.2 | When a filter invokes the doFilter method on the container's filter chain implementation, the container must ensure that the request and response object that it passes to the next entity in the filter chain, or to the target web resource if the filter was the last in the chain, is the same object that was passed into the doFilter method by the calling filter. | true |  | false | technology | active | true
Servlet:SPEC:51 | 6 | 2.2 | The same requirement of wrapper object identity applies to the calls from a servlet or a filter to RequestDispatcher.forward or RequestDispatcher.include, when the caller wraps the request or response objects. In this case, the request and response objects seen by the called servlet must be the same wrapper objects that were passed in by the calling servlet or filter. | true |  | false | technology | active | true
Servlet:SPEC:52 | 6 | 2.4 | The order the container uses in building the chain of filters to be applied for a particular request URI is as follows: | true |  | false | technology | active | true

Servlet:SPEC:259 | 8 | 2.4 | In addition to supporting fragments and use of annotations one of the requirements is that not only we be able to plug-in things that are bundled in the WEB-INF/lib but also plugin shared copies of frameworks - including being able to plug-in to the web container things like JAX-WS, JAX-RS and JSF that build on top of the web container. The ServletContainerInitializer allows handling such a use case as described below. | true |  | false | platform | active | true
Servlet:SPEC:259.1 | 8 | 2.4 | The ServletContainerInitializer class is looked up via the jar services API. For each application, an instance of the ServletContainerInitializer is created by the container at application startup time.

Servlet:SPEC:259.2 | 8 | 2.4 | In addition to the ServletContainerInitializer we also have an annotation - HandlesTypes. The HandlesTypes annotation on the implementation of the ServletContainerInitializer is used to express interest in classes that may have anotations (type, method or field level annotations) specified in the value of the HandlesTypes or if it extends / implements one those classes anywhere in the class' super types. The HandlesTypes annotation is applied irrespective of the setting of metadata-complete. The container uses the HandlesTypes annotation to determine when to invoke the initializer's onStartup method. When examining the classes of an application to see if they match any of the criteria specified by the HandlesTypes annotation of a ServletContainerInitializer, the container may run into class loading problems if one or more of the application's optional JAR files are missing. Since the container is not in a position to decide whether these types of class loading failures will prevent the application from working correctly, it must ignore them, while at the same time providing a configuration option that would log them. | true |  | false | platform | active | true
Servlet:SPEC:259.3 | 8 | 2.4 | If an implementation of ServletContainerInitializer does not have the @HandlesTypes annotation, or if there are no matches to any of the HandlesType specified, then it will get invoked once for every application with null as the value of the Set. This will allow for the initializer to determine based on the resources available in the application whether it needs to initialize a servet / filter or not. | true |  | false | platform | active | true
Servlet:SPEC:259.4 | 8 | 2.4 | The onStartup method of the ServletContainerInitializer will be invoked when the application is coming up before any of the listener's events are fired. | true |  | false | platform | active | true

Servlet:SPEC:259.6 | 8 | 2.4 | The framework jar file can also be bundled in WEB-INF/lib directory of the war file. If the ServletContainerInitializer is bundled in a JAR file inside the WEB-INF/lib directory of an application, it's onStartup method will be invoked only once during the startup of the bundling application. If, on the other hand, the ServletContainerInitialzer is bundled in a JAR file outside of the WEB-INF/lib directory, but still discoverable by the runtime's service provider lookup mechanism, it's onStartup method will be invoked every time an application is started. | true |  | false | platform | active | true
Servlet:SPEC:259.7 | 8 | 2.4 | Implementations of the ServletContainerInitializer interface will be discovered by the runtime's service lookup mechanism or a container specific mechanism that is semantically equivalent to it.
