Method Detail

loadClass

public Class<?> loadClass(String name)
                   throws ClassNotFoundException

not really necessary now, but we keep it for reference for a future classloader per extension for allowing extensions to use differently versioned dependency jars in separate subfolders under lib/ext//

Overrides:

loadClass in class ClassLoader

Throws:

ClassNotFoundException

getResource

public URL getResource(String name)

THIS IS A WORKAROUND! java9 fails to resolve if the resource contains a leading slash e.g. /org/freevoice/jumpdbqueryextension/dbquerystrings.properties fails with null while org/freevoice/jumpdbqueryextension/dbquerystrings.properties will properly resolve to jar:file:lib/plus/jumpdbquery.jar!/org/freevoice/jumpdbqueryextension/dbquerystrings.properties

Overrides:

getResource in class ClassLoader

addUrls

public void addUrls(URL[] urls)

allow adding urls, any time

Parameters:

urls - array of URLs to add
