Class ResolverDirectHTTP

java.lang.Object

org.apache.xml.security.utils.resolver.ResourceResolverSpi

org.apache.xml.security.utils.resolver.implementations.ResolverDirectHTTP

public class ResolverDirectHTTP
extends ResourceResolverSpi

A simple ResourceResolver for HTTP requests. This class handles only 'pure' HTTP URIs which means without a fragment. The Fragment handling is done by the ResolverFragment class.
If the user has a corporate HTTP proxy which is to be used, the usage can be switched on by setting properties for the resolver:

 resourceResolver.setProperty("http.proxy.host", "proxy.company.com");
 resourceResolver.setProperty("http.proxy.port", "8080");

 // if we need a password for the proxy
 resourceResolver.setProperty("http.proxy.username", "proxyuser3");
 resourceResolver.setProperty("http.proxy.password", "secretca");

Method Detail

engineIsThreadSafe

public boolean engineIsThreadSafe()

Description copied from class: ResourceResolverSpi

Tells if the implementation does can be reused by several threads safely. It normally means that the implementation does not have any member, or there is member change between engineCanResolve and engineResolve invocations. Or it maintains all member info in ThreadLocal methods.

Overrides:

engineIsThreadSafe in class ResourceResolverSpi

engineResolveURI

public XMLSignatureInput engineResolveURI(ResourceResolverContext context)
                                   throws ResourceResolverException

This is the workhorse method used to resolve resources.

Specified by:

engineResolveURI in class ResourceResolverSpi

Parameters:

context - Context to use to resolve resources.

Returns:

the resource wrapped around a XMLSignatureInput

Throws:

ResourceResolverException

openConnection

private java.net.URLConnection openConnection(java.net.URL url)
                                       throws java.io.IOException

Throws:

java.io.IOException

engineCanResolveURI

public boolean engineCanResolveURI(ResourceResolverContext context)

We resolve http URIs without fragment...

Specified by:

engineCanResolveURI in class ResourceResolverSpi

Parameters:

context -

Returns:

true if can be resolved

engineGetPropertyKeys

public java.lang.String[] engineGetPropertyKeys()

Method engineGetPropertyKeys

Overrides:

engineGetPropertyKeys in class ResourceResolverSpi

Returns:

the property keys

getNewURI

private static java.net.URI getNewURI(java.lang.String uri,
                                      java.lang.String baseURI)
                               throws java.net.URISyntaxException

Throws:

java.net.URISyntaxException
