@Deprecated public class SpaceFinder extends Object
Deprecated.
Use UrlSpaceConfigurer instead.
 This utility class provides accessing to Container proxy
 or Space proxy (IJSpace).

  The SpaceFinder is designed to provide a unified interface for finding a
 space/container in each of the mode specified.
 In addition to the lookup option there is another option of finding the space
 via its container.
  To provide a unified manager of accessing the space in any of the above modes
 we will use a url based interface which will provide the information of the
 protocol and the address of the space that should be found.

 The general format for this URL is as follows:

 Protocol://[host]:[port]/[container_name]/[space_name]?[query_string]

 Protocol: [ rmi | jini | java ]
           The "java" protocol enables working with an embedded space. When choosing so
           one should specify in the query string one of three space operations:

           > create - to create a new space
            example of "mySpace" space creation:

            java://myHost/myContinaer/mySpace?create

           > open - To open  an existing space in an embedded mode:
            example of opening "mySpace" space:

            java://myHost/myContinaer/mySpace?open

           > destroy - for destroy  an existing space:
            example of destroying "mySpace" space:

            java://myHost/myContinaer/mySpace?destroy

 Host: The host name. Can be '*', when JINI is used as a protocol, the host
       value determines whether to use Unicast or Multicast.

 Port: the registry or lookup port. If the port is  not specified,
       the default port 10098 will be used.

 Container Name: The name of the container, which holds the space.
                 If the container name is '*' then the container attribute will be ignored and
 the
                 space will be looked for directly regardless of the container that holds it .

 Examples of space url's:

 1. Looking for a space using JINI Unicast protocol.
    jini://mylookuphost/mycontainername/myspace
  Or
    jini://*/*/myspace

 2. Looking for a space using the JINI multicast protocol.
    jini://*/containername/myspace
  Or
    jini://*/*/myspace

 3. looking for a container regardless of the space it contains in any of the above methods:
    jini://mylookuphost/mycontainername
    jini://*/mycontainername

      Verifies for validation if the specified url is valid and returns SpaceURL object that contains all information about specified url. This method also support multiple URLs separate by ";"
      Parameters:
      url - The url to verify.

    • find

      public static Object find(String[] urls) throws FinderException
      Deprecated.
      SpaceFinder.find multiple URL provides ability to define space search order. It is useful when Jini URL for locating services on the network is not available. If the first space URL is unavailable, SpaceFinder will try the next one until a live proxy will be found. If all URLs are unavailable this method throws FinderException
      Parameters:
      urls - Array of SpaceFinder URLs.
      Returns:
      Returns single found proxy.
      Throws:
      FinderException - Failed to found proxy.All URLs are unavailable.
