ServletContext (Red Hat JBoss Enterprise Application Platform 7.0.0.GA public API)

All Known Implementing Classes:

ServletContextImpl
```
public interface ServletContext
```
Defines a set of methods that a servlet uses to communicate with its servlet container, for example, to get the MIME type of a file, dispatch requests, or write to a log file.
There is one context per "web application" per Java Virtual Machine. (A "web application" is a collection of servlets and content installed under a specific subset of the server's URL namespace such as /catalog and possibly installed via a .war file.)
In the case of a web application marked "distributed" in its deployment descriptor, there will be one context instance for each virtual machine. In this situation, the context cannot be used as a location to share global information (because the information won't be truly global). Use an external resource like a database instead.
The ServletContext object is contained within the ServletConfig object, which the Web server provides the servlet when the servlet is initialized.

    See Also:
    
    Constant Field Values
  - ORDERED_LIBS
```
static final String ORDERED_LIBS
```
    The name of the ServletContext attribute whose value (of type java.util.List<java.lang.String>) contains the list of names of JAR files in WEB-INF/lib ordered by their web fragment names (with possible exclusions if <absolute-ordering> without any <others/> is being used), or null if no absolute or relative ordering has been specified

    Constant Field Values
- Method Detail
  - getContextPath
```
String getContextPath()
```
    Returns the context path of the web application.
    The context path is the portion of the request URI that is used to select the context of the request. The context path always comes first in a request URI. If this context is the “default” context rooted at the base of the Web server’s URL name space, this path will be an empty string. Otherwise, if the context is not rooted at the root of the server’s name space, the path starts with a / character but does not end with a / character.
    It is possible that a servlet container may match a context by more than one context path. In such cases the HttpServletRequest.getContextPath() will return the actual context path used by the request and it may differ from the path returned by this method. The context path returned by this method should be considered as the prime or preferred context path of the application.
    
    Returns:
    
    The context path of the web application, or "" for the default (root) context
    
    Since:
    
    Servlet 2.5
    
    See Also:
    
    HttpServletRequest.getContextPath()
  - getContext
```
ServletContext getContext(String uripath)
```
    Returns a ServletContext object that corresponds to a specified URL on the server.
    This method allows servlets to gain access to the context for various parts of the server, and as needed obtain RequestDispatcher objects from the context. The given path must be begin with /, is interpreted relative to the server's document root and is matched against the context roots of other web applications hosted on this container.
    In a security conscious environment, the servlet container may return null for a given URL.
    
    Parameters:
    
    uripath - a String specifying the context path of another web application in the container.
    
    Returns:
    
    the ServletContext object that corresponds to the named URL, or null if either none exists or the container wishes to restrict this access.

  - getMajorVersion
```
int getMajorVersion()
```
    Returns the major version of the Servlet API that this servlet container supports. All implementations that comply with Version 3.0 must have this method return the integer 3.
    
    Returns:
    
    3
  - getMinorVersion
```
int getMinorVersion()
```
    Returns the minor version of the Servlet API that this servlet container supports. All implementations that comply with Version 3.0 must have this method return the integer 0.
    
    Returns:
    
    0
  - getEffectiveMajorVersion
```
int getEffectiveMajorVersion()
```
    Gets the major version of the Servlet specification that the application represented by this ServletContext is based on.
    The value returned may be different from getMajorVersion(), which returns the major version of the Servlet specification supported by the Servlet container.
    
    Returns:
    
    the major version of the Servlet specification that the application represented by this ServletContext is based on
    
    Throws:
    
    UnsupportedOperationException - if this ServletContext was passed to the ServletContextListener.contextInitialized(javax.servlet.ServletContextEvent) method of a ServletContextListener that was neither declared in web.xml or web-fragment.xml, nor annotated with WebListener
    
    Since:
    
    Servlet 3.0
  - getEffectiveMinorVersion
```
int getEffectiveMinorVersion()
```
    Gets the minor version of the Servlet specification that the application represented by this ServletContext is based on.
    The value returned may be different from getMinorVersion(), which returns the minor version of the Servlet specification supported by the Servlet container.
    
    Returns:
    
    the minor version of the Servlet specification that the application xrepresented by this ServletContext is based on
    
    Throws:
    
    UnsupportedOperationException - if this ServletContext was passed to the ServletContextListener.contextInitialized(javax.servlet.ServletContextEvent) method of a ServletContextListener that was neither declared in web.xml or web-fragment.xml, nor annotated with WebListener
    
    Since:
    
    Servlet 3.0
  - getMimeType
```
String getMimeType(String file)
```
    Returns the MIME type of the specified file, or null if the MIME type is not known. The MIME type is determined by the configuration of the servlet container, and may be specified in a web application deployment descriptor. Common MIME types include text/html and image/gif.
    
    Parameters:
    
    file - a String specifying the name of a file
    
    Returns:
    
    a String specifying the file's MIME type
  - getResourcePaths
```
Set<String> getResourcePaths(String path)
```
    Returns a directory-like listing of all the paths to resources within the web application whose longest sub-path matches the supplied path argument.
    Paths indicating subdirectory paths end with a /.
    The returned paths are all relative to the root of the web application, or relative to the /META-INF/resources directory of a JAR file inside the web application's /WEB-INF/lib directory, and have a leading /.
    For example, for a web application containing:
```
   /welcome.html
   /catalog/index.html
   /catalog/products.html
   /catalog/offers/books.html
   /catalog/offers/music.html
   /customer/login.jsp
   /WEB-INF/web.xml
   /WEB-INF/classes/com.acme.OrderServlet.class
   /WEB-INF/lib/catalog.jar!/META-INF/resources/catalog/moreOffers/books.html
 
```
    getResourcePaths("/") would return {"/welcome.html", "/catalog/", "/customer/", "/WEB-INF/"}, and getResourcePaths("/catalog/") would return {"/catalog/index.html", "/catalog/products.html", "/catalog/offers/", "/catalog/moreOffers/"}.
    Parameters:
    
    path - the partial path used to match the resources, which must start with a /
    
    Returns:
    
    a Set containing the directory listing, or null if there are no resources in the web application whose path begins with the supplied path.
    
    Since:
    
    Servlet 2.3
  - getResource
```
URL getResource(String path)
         throws MalformedURLException
```
    Returns a URL to the resource that is mapped to the given path.
    The path must begin with a / and is interpreted as relative to the current context root, or relative to the /META-INF/resources directory of a JAR file inside the web application's /WEB-INF/lib directory. This method will first search the document root of the web application for the requested resource, before searching any of the JAR files inside /WEB-INF/lib. The order in which the JAR files inside /WEB-INF/lib are searched is undefined.
    This method allows the servlet container to make a resource available to servlets from any source. Resources can be located on a local or remote file system, in a database, or in a .war file.
    The servlet container must implement the URL handlers and URLConnection objects that are necessary to access the resource.
    This method returns null if no resource is mapped to the pathname.
    Some containers may allow writing to the URL returned by this method using the methods of the URL class.
    The resource content is returned directly, so be aware that requesting a .jsp page returns the JSP source code. Use a RequestDispatcher instead to include results of an execution.
    This method has a different purpose than java.lang.Class.getResource, which looks up resources based on a class loader. This method does not use class loaders.
    
    Parameters:
    
    path - a String specifying the path to the resource
    
    Returns:
    
    the resource located at the named path, or null if there is no resource at that path
    
    Throws:
    
    MalformedURLException - if the pathname is not given in the correct form
  - getResourceAsStream
```
InputStream getResourceAsStream(String path)
```
    Returns the resource located at the named path as an InputStream object.
    The data in the InputStream can be of any type or length. The path must be specified according to the rules given in getResource. This method returns null if no resource exists at the specified path.
    Meta-information such as content length and content type that is available via getResource method is lost when using this method.
    The servlet container must implement the URL handlers and URLConnection objects necessary to access the resource.
    This method is different from java.lang.Class.getResourceAsStream, which uses a class loader. This method allows servlet containers to make a resource available to a servlet from any location, without using a class loader.
    
    Parameters:
    
    path - a String specifying the path to the resource
    
    Returns:
    
    the InputStream returned to the servlet, or null if no resource exists at the specified path
  - getRequestDispatcher
```
RequestDispatcher getRequestDispatcher(String path)
```
    Returns a RequestDispatcher object that acts as a wrapper for the resource located at the given path. A RequestDispatcher object can be used to forward a request to the resource or to include the resource in a response. The resource can be dynamic or static.
    The pathname must begin with a / and is interpreted as relative to the current context root. Use getContext to obtain a RequestDispatcher for resources in foreign contexts.
    This method returns null if the ServletContext cannot return a RequestDispatcher.
    
    Parameters:
    
    path - a String specifying the pathname to the resource
    
    Returns:
    
    a RequestDispatcher object that acts as a wrapper for the resource at the specified path, or null if the ServletContext cannot return a RequestDispatcher
    
    See Also:
    
    RequestDispatcher, getContext(java.lang.String)
  - getNamedDispatcher
```
RequestDispatcher getNamedDispatcher(String name)
```
    Returns a RequestDispatcher object that acts as a wrapper for the named servlet.
    Servlets (and JSP pages also) may be given names via server administration or via a web application deployment descriptor. A servlet instance can determine its name using ServletConfig.getServletName().
    This method returns null if the ServletContext cannot return a RequestDispatcher for any reason.
    
    Parameters:
    
    name - a String specifying the name of a servlet to wrap
    
    Returns:
    
    a RequestDispatcher object that acts as a wrapper for the named servlet, or null if the ServletContext cannot return a RequestDispatcher
    
    See Also:
    
    RequestDispatcher, getContext(java.lang.String), ServletConfig.getServletName()
  - getServlet
```

```
    Deprecated. As of Java Servlet API 2.1, with no direct replacement.
    This method was originally defined to retrieve a servlet from a ServletContext. In this version, this method always returns null and remains only to preserve binary compatibility. This method will be permanently removed in a future version of the Java Servlet API.
    In lieu of this method, servlets can share information using the ServletContext class and can perform shared business logic by invoking methods on common non-servlet classes.

    msg - a String specifying the message to be written to the log file
  - log
```
void log(Exception exception,
         String msg)

  - log
```
void log(String message,
         Throwable throwable)
```
    Writes an explanatory message and a stack trace for a given Throwable exception to the servlet log file. The name and type of the servlet log file is specific to the servlet container, usually an event log.

    message - a String that describes the error or exception
    
    throwable - the Throwable error or exception
  - getRealPath
```
String getRealPath(String path)
```
    Gets the real path corresponding to the given virtual path.
    For example, if path is equal to /index.html, this method will return the absolute file path on the server's filesystem to which a request of the form http://<host>:<port>/<contextPath>/index.html would be mapped, where <contextPath> corresponds to the context path of this ServletContext.
    The real path returned will be in a form appropriate to the computer and operating system on which the servlet container is running, including the proper path separators.
    Resources inside the /META-INF/resources directories of JAR files bundled in the application's /WEB-INF/lib directory must be considered only if the container has unpacked them from their containing JAR file, in which case the path to the unpacked location must be returned.
    This method returns null if the servlet container is unable to translate the given virtual path to a real path.
    
    Parameters:
    
    path - the virtual path to be translated to a real path
    
    Returns:
    
    the real path, or null if the translation cannot be performed
  - getServerInfo
```
String getServerInfo()
```
    Returns the name and version of the servlet container on which the servlet is running.
    The form of the returned string is servername/versionnumber. For example, the JavaServer Web Development Kit may return the string JavaServer Web Dev Kit/1.0.
    The servlet container may return other optional information after the primary string in parentheses, for example, JavaServer Web Dev Kit/1.0 (JDK 1.1.6; Windows NT 4.0 x86).

    Parameters:
    
    name - the name of the context initialization parameter to set
    
    value - the value of the context initialization parameter to set
    
    Returns:
    
    true if the context initialization parameter with the given name and value was set successfully on this ServletContext, and false if it was not set because this ServletContext already contains a context initialization parameter with a matching name
    
    Throws:
    
    IllegalStateException - if this ServletContext has already been initialized
    
    UnsupportedOperationException - if this ServletContext was passed to the ServletContextListener.contextInitialized(javax.servlet.ServletContextEvent) method of a ServletContextListener that was neither declared in web.xml or web-fragment.xml, nor annotated with WebListener

    Servlet 3.0
  - getAttribute
```
Object getAttribute(String name)
```
    Returns the servlet container attribute with the given name, or null if there is no attribute by that name.
    An attribute allows a servlet container to give the servlet additional information not already provided by this interface. See your server documentation for information about its attributes. A list of supported attributes can be retrieved using getAttributeNames.
    The attribute is returned as a java.lang.Object or some subclass.
    Attribute names should follow the same convention as package names. The Java Servlet API specification reserves names matching java.*, javax.*, and sun.*.
    
    Parameters:
    
    name - a String specifying the name of the attribute
    
    Returns:
    
    an Object containing the value of the attribute, or null if no attribute exists matching the given name
    
    See Also:
    
    getAttributeNames()
  - getAttributeNames
```
Enumeration<String> getAttributeNames()
```
    Returns an Enumeration containing the attribute names available within this ServletContext.

    Returns:
    
    an Enumeration of attribute names
    
    See Also:
    
    getAttribute(java.lang.String)
  - setAttribute
```
void setAttribute(String name,
                  Object object)
```
    Binds an object to a given attribute name in this ServletContext. If the name specified is already used for an attribute, this method will replace the attribute with the new to the new attribute.
    If listeners are configured on the ServletContext the container notifies them accordingly.
    If a null value is passed, the effect is the same as calling removeAttribute().
    Attribute names should follow the same convention as package names. The Java Servlet API specification reserves names matching java.*, javax.*, and sun.*.
    
    Parameters:
    
    name - a String specifying the name of the attribute
    
    object - an Object representing the attribute to be bound
  - removeAttribute

```
    Removes the attribute with the given name from this ServletContext. After removal, subsequent calls to getAttribute(java.lang.String) to retrieve the attribute's value will return null.
    If listeners are configured on the ServletContext the container notifies them accordingly.
    
    Parameters:
    
    name - a String specifying the name of the attribute to be removed
  - getServletContextName
```
String getServletContextName()
```
    Returns the name of this web application corresponding to this ServletContext as specified in the deployment descriptor for this web application by the display-name element.

The returned value is NOT expected or required to be equivalent to a network address or hostname of the logical host.
    
    Returns:
    
    a String containing the configuration name of the logical host on which the servlet context is deployed.
    
    Throws:
    
    UnsupportedOperationException - if this ServletContext was passed to the ServletContextListener.contextInitialized(javax.servlet.ServletContextEvent) method of a ServletContextListener that was neither declared in web.xml or web-fragment.xml, nor annotated with WebListener
