Interface ServletContext

```
public interface ServletContext
```
A class created by the server to give servlets access to certain environment related objects and methods.
It contains standard information like the names of all the servlets, two kinds of log methods, the server name, etc.
The server can also store extra information here in the form of {String, Object} pairs. Different servlets can live in different ServletContexts, but a servlet engine can group related Servlets in the same ServletContext.
Servlet specific information can be transferred to a servlet using a class implementing the ServletConfig interface.

Since:

1.0

    2.5
  - getContext
```
ServletContext getContext(java.lang.String UriPath)
```
    Gives the ServletContext of another servlet indicated by the UriPath on the same server. For security reasons this can return null even if there is an active servlet at that location. This can then be used to set attributes in the context of another servlet.
    
    Parameters:
    UriPath - The path to the servlet, such as /servlet/ShowBook
    
    Returns:
    ServletContext of the requested servlet or null if there is no servlet at the requested UriPath or when it is unavailable due to security restrictions
    Since:
    
    2.1
    
    See Also:
    setAttribute(java.lang.String, java.lang.Object)
  - getMajorVersion

```

    Since:
    
    2.1
  - getMinorVersion
```
int getMinorVersion()
```
    Minor version number of the Servlet API the servlet engine supports.

  - getEffectiveMajorVersion
```

  - getEffectiveMinorVersion
```

    3.0
  - getMimeType
```
java.lang.String getMimeType(java.lang.String filename)
```
    Gives the mimetype of the requested file
    
    Parameters:
    filename - the file
    
    Returns:
    a String containing the mime type or null if the mime type cannot be determined
    Since:
    
    1.0
  - getResourcePaths
```
java.util.Set getResourcePaths(java.lang.String pathPrefix)
```
    Returns a listing of all the resources that are accessible inside this web application, whose paths start with the path provided specified. This path must start with a "/", and all paths in the resulting set will be relative to the root of the web application So a call of getResourcePaths ("/images/jpegs/") might yield the set {"/images/jpegs/a.jpg","/images/jpegs/b.jpg,..."}
    
    Parameters:
    pathPrefix - The path starting with "/" used to match against the resources
    
    Returns:
    a Set containing the paths of the matching resources or null if no resources with the specified prefix can be found
    Since:
    
    2.3
  - getResource
```
java.net.URL getResource(java.lang.String virtualPath)
 throws java.net.MalformedURLException
```
    Translates the requested virtual path to an URL object that can be accesed by the servlet. This is more generic than the getRealPath method since it is not tied to the local filesystem. This means that a servlet can access the resource even when loaded in a servlet engine on a different machine. The servlet engine should make sure that the appropriate URLStreamHandlers and URLConnection classes are implemented to acces to resource.
    This can also be used to write to a resource if the resource (URLConnection) supports it. The following example gives you an OutputStream:
    
    URLConnection con = getResource("/logs/mylog.txt").openConnection(); con.setDoOutput(true); OutputStream out = con.getOutputStream();
    Note that a ServerContext does not have to have access to the complete servers document space and is allowed to return null even for valid virtual paths.
    Note that according to the 2.1 API documentation this method can throw a MalformedURLException. But according to the official spec it does not throw any exceptions.
    
    Parameters:
    virtualPath - the path to the requested resource (e.g. /philosophy/words-to-avoid.html)
    
    Returns:
    the URL that can be used to access the resource or null if the resource cannot be found
    
    Throws:
    
    java.net.MalformedURLException
    Since:
    
    2.1
    
    See Also:
    URL.openConnection(), URLConnection.setDoOutput(boolean), URLConnection.getOutputStream()
  - getResourceAsStream
```
java.io.InputStream getResourceAsStream(java.lang.String virtualPath)
```
    A convenience method for getResource(virtualPath).openStream(). But the servlet engine is allowed to implement is in a more efficient way.
    
    Parameters:
    virtualPath - the path to the requested resource (e.g. /philosophy/words-to-avoid.html)
    
    Returns:
    the InputStream that can be used to read the resource or null if the resource cannot be found
    Since:
    
    2.1
    
    See Also:
    getResource(java.lang.String), URL.openStream()
  - getRequestDispatcher

    Returns:
    an RequestDispatcher for the (active) resource found at UriPath
