public class ResourceHandler
extends AbstractHandler

Resource Handler. This handle will serve static content and handle If-Modified-Since headers. No caching is done. Requests that cannot be handled are let pass (Eg no 404's)

ResourceHandler

public ResourceHandler()

Method Detail

getMimeTypes

public MimeTypes getMimeTypes()

setMimeTypes

public void setMimeTypes(MimeTypes mimeTypes)

isAliases

public boolean isAliases()

Returns:

True if resource aliases are allowed.

setAliases

public void setAliases(boolean aliases)

Set if resource aliases (eg symlink, 8.3 names, case insensitivity) are allowed. Allowing aliases can significantly increase security vulnerabilities. If this handler is deployed inside a ContextHandler, then the ContextHandler.isAliases() takes precedent.

Parameters:

aliases - True if aliases are supported.

isDirectoriesListed

public boolean isDirectoriesListed()

Get the directory option.

Returns:

true if directories are listed.

setDirectoriesListed

public void setDirectoriesListed(boolean directory)

Set the directory.

Parameters:

directory - true if directories are listed.

doStart

public void doStart()
             throws Exception

Overrides:

doStart in class AbstractHandler

Throws:

Exception

getBaseResource

public Resource getBaseResource()

Returns:

Returns the resourceBase.

getResourceBase

public String getResourceBase()

Returns:

Returns the base resource as a string.

setBaseResource

public void setBaseResource(Resource base)

Parameters:

base - The resourceBase to set.

setResourceBase

public void setResourceBase(String resourceBase)

Parameters:

resourceBase - The base resource as a string.

getStylesheet

public Resource getStylesheet()

Returns:

Returns the stylesheet as a Resource.

setStylesheet

public void setStylesheet(String stylesheet)

Parameters:

stylesheet - The location of the stylesheet to be used as a String.

getCacheControl

public String getCacheControl()

Returns:

the cacheControl header to set on all static content.

setCacheControl

public void setCacheControl(String cacheControl)

Parameters:

cacheControl - the cacheControl header to set on all static content.

getResource

public Resource getResource(String path)
                     throws MalformedURLException

Throws:

MalformedURLException
