javax.servlet
Interface ServletContext


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.

Method Detail

getContext

ServletContext getContext(java.lang.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.

getMimeType

java.lang.String getMimeType(java.lang.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 are "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

java.util.Set<java.lang.String> getResourcePaths(java.lang.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 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,

getResourcePaths("/") returns {"/welcome.html", "/catalog/", "/customer/", "/WEB-INF/"}
getResourcePaths("/catalog/") returns {"/catalog/index.html", "/catalog/products.html", "/catalog/offers/"}.

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

java.net.URL getResource(java.lang.String path)
                         throws java.net.MalformedURLException
Returns a URL to the resource that is mapped to a specified path. The path must begin with a "/" and is interpreted as relative to the current context root.

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:
java.net.MalformedURLException - if the pathname is not given in the correct form

getResourceAsStream

java.io.InputStream getResourceAsStream(java.lang.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(java.lang.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(java.lang.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()

Servlet getServlet(java.lang.String name)
                   throws ServletException
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.

Throws:
ServletException

getServlets

java.util.Enumeration<Servlet> getServlets()
Deprecated. As of Java Servlet API 2.0, with no replacement.

This method was originally defined to return an Enumeration of all the servlets known to this servlet context. In this version, this method always returns an empty enumeration and remains only to preserve binary compatibility. This method will be permanently removed in a future version of the Java Servlet API.


getServletNames

java.util.Enumeration<java.lang.String> getServletNames()
Deprecated. As of Java Servlet API 2.1, with no replacement.

This method was originally defined to return an Enumeration of all the servlet names known to this context. In this version, this method always returns an empty Enumeration and remains only to preserve binary compatibility. This method will be permanently removed in a future version of the Java Servlet API.


log

void log(java.lang.String msg)
Writes the specified message to a servlet log file, usually an event log. The name and type of the servlet log file is specific to the servlet container.

Parameters:
msg - a String specifying the message to be written to the log file

log

void log(java.lang.Exception exception,
         java.lang.String msg)
Deprecated. As of Java Servlet API 2.1, use log(String message, Throwable throwable) instead.

This method was originally defined to write an exception's stack trace and an explanatory error message to the servlet log file.


log

void log(java.lang.String message,
         java.lang.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.

Parameters:
message - a String that describes the error or exception
throwable - the Throwable error or exception

getRealPath

java.lang.String getRealPath(java.lang.String path)
Returns a String containing the real path for a given virtual path. For example, the path "/index.html" returns the absolute file path on the server's filesystem would be served by a request for "http://host/contextPath/index.html", where contextPath is 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. This method returns null if the servlet container cannot translate the virtual path to a real path for any reason (such as when the content is being made available from a .war archive).

Parameters:
path - a String specifying a virtual path
Returns:
a String specifying the real path, or null if the translation cannot be performed

getServerInfo

java.lang.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).

Returns:
a String containing at least the servlet container name and version number

getInitParameter

java.lang.String getInitParameter(java.lang.String name)
Returns a String containing the value of the named context-wide initialization parameter, or null if the parameter does not exist.

This method can make available configuration information useful to an entire "web application". For example, it can provide a webmaster's email address or the name of a system that holds critical data.

Parameters:
name - a String containing the name of the parameter whose value is requested
Returns:
a String containing at least the servlet container name and version number
See Also:
ServletConfig.getInitParameter(java.lang.String)

Servlet 3.0 TODO SERVLET3 - Add comments

getAttribute

java.lang.Object getAttribute(java.lang.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

java.util.Enumeration<java.lang.String> getAttributeNames()
Returns an Enumeration containing the attribute names available within this servlet context. Use the getAttribute(java.lang.String) method with an attribute name to get the value of an attribute.

Returns:
an Enumeration of attribute names
See Also:
getAttribute(java.lang.String)

setAttribute

void setAttribute(java.lang.String name,
                  java.lang.Object object)
Binds an object to a given attribute name in this servlet context. 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

void removeAttribute(java.lang.String name)
Removes the attribute with the given name from the servlet context. 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

java.lang.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.
