public class DefaultTagLibraryResolver
DefaultTagLibraryResolver is a default implemenation
which attempts to interpret the URI as a String called 'jelly:className'
and class load the given Java class. Otherwise META-INF/services/jelly/uri
is searched for on the thread context's class path and, if found, that
class will be loaded.

|---|---|
java.lang.ClassLoader |
getClassLoader()
Return the class loader to be used for instantiating application objects when required. |

getDiscoverClasses()
|
boolean |
getUseContextClassLoader()
Return the boolean as to whether the context classloader should be used. |
protected TagLibrary |
loadClass(java.lang.String uri,
java.lang.String className)
Instantiates the given class name. |
protected TagLibrary |
newInstance(java.lang.String uri,
java.lang.Class theClass)
Creates a new instance of the given TagLibrary class or return null if it could not be instantiated. |
TagLibrary |
resolveTagLibrary(java.lang.String uri)
Attempts to resolve the given URI to be associated with a TagLibrary otherwise null is returned to indicate no tag library could be found so that the namespace URI should be treated as just vanilla XML. |

setClassLoader(java.lang.ClassLoader classLoader)
Set the class loader to be used for instantiating application objects when required. |
void |
setDiscoverClasses(org.apache.commons.discovery.resource.classes.DiscoverClasses discovery)
Sets the fully configured DiscoverClasses instance to be used to lookup services |
void |
setUseContextClassLoader(boolean use)
