ServletContainer (Jersey 3.0.10 API)

java.lang.Object
- jakarta.servlet.GenericServlet
- - jakarta.servlet.http.HttpServlet
  - - org.glassfish.jersey.servlet.ServletContainer

All Implemented Interfaces:

jakarta.servlet.Filter, jakarta.servlet.Servlet, jakarta.servlet.ServletConfig, Serializable, Container
```
public class ServletContainer
extends jakarta.servlet.http.HttpServlet
implements jakarta.servlet.Filter, Container
```
A Servlet or Filter for deploying root resource classes.
The following sections make reference to initialization parameters. Unless otherwise specified the initialization parameters apply to both server and filter initialization parameters.
The servlet or filter may be configured to have an initialization parameter (see ServletProperties.JAXRS_APPLICATION_CLASS) and whose value is a fully qualified name of a class that implements Application. The class is instantiated as a singleton component managed by the runtime, and injection may be performed (the artifacts that may be injected are limited to injectable providers registered when the servlet or filter is configured).
If the initialization parameter is not present and a initialization parameter "jersey.config.server.provider.packages" is present (see ServerProperties.PROVIDER_PACKAGES) a new instance of ResourceConfig with this configuration is created. The initialization parameter "jersey.config.server.provider.packages" MUST be set to provide one or more package names. Each package name MUST be separated by ';'.
If none of the above resource configuration related initialization parameters are present a new instance of ResourceConfig with WebAppResourcesScanner is created. The initialization parameter "jersey.config.server.provider.classpath" is present (see ServerProperties.PROVIDER_CLASSPATH) MAY be set to provide one or more resource paths. Each path MUST be separated by ';'. If the initialization parameter is not present then the following resource paths are utilized: "/WEB-INF/lib" and "/WEB-INF/classes".
All initialization parameters are added as properties of the created ResourceConfig.
A new ApplicationHandler instance will be created and configured such that the following classes may be injected onto a root resource, provider and Application classes using @Context annotation: HttpServletRequest, HttpServletResponse, ServletContext, ServletConfig and WebConfig. If this class is used as a Servlet then the ServletConfig class may be injected. If this class is used as a servlet filter then the FilterConfig class may be injected. WebConfig may be injected to abstract servlet or filter deployment.
Persistence units that may be injected must be configured in web.xml in the normal way plus an additional servlet parameter to enable the Jersey servlet to locate them in JNDI. E.g. with the following persistence unit configuration:
```
 <persistence-unit-ref>
     <persistence-unit-ref-name>persistence/widget</persistence-unit-ref-name>
     <persistence-unit-name>WidgetPU</persistence-unit-name>
 </persistence-unit-ref>
 
```
the Jersey servlet requires an additional servlet parameter as follows:
```
 <init-param>
     <param-name>unit:WidgetPU</param-name>
     <param-value>persistence/widget</param-value>
 </init-param>
 
```
Given the above, Jersey will inject the EntityManagerFactory found at java:comp/env/persistence/widget in JNDI when encountering a field or parameter annotated with @PersistenceUnit(unitName="WidgetPU").

    Dispatches client requests to the service(URI, URI, HttpServletRequest, HttpServletResponse) method.

    request - the HttpServletRequest object that contains the request the client made to the servlet.
    
    response - the HttpServletResponse object that contains the response the servlet returns to the client.
    
    chain - the chain of filters from which the next filter can be invoked.
    
    Throws:
    
    IOException - in case of an I/O error.
    
    jakarta.servlet.ServletException - in case of an error while executing the filter chain.

```
    Get the static content path pattern.
    
    Returns:
