Method Detail

resolve

public URILocation resolve(String href,
                           String documentBase)
                    throws URIException

Resolves the given href and documentBase. The href can either be an absolute or a relative URI as defined by IETF RFC 2396:

• Absolute URI: [scheme]:'//'[authority][absolute path]
• Relative URI: '//'[authority][absolute path] or [relative path] or [absolute path].

Note:

1. When [authority] is not used then '//' must not be used.
2. An [absolute path] begins by a '/' sign.

For instance the following URIs are valid:

        file:/c:/Program Files/MyApp/myresource.xml
        file://usr/etc/myresource.xml
        http://www.castor.org/index.html
        ../relative/index.html
    

However, the following won't be valid:

        file://c:/Program Files/MyApp/myresource.xml
