public MdsQuery()

C'tor for the class.

MdsQuery

public MdsQuery(String host,
                int port)

Valid C'tor for the class to create a MdsQuery object. Sets the SECURITY_ATHENTICATION with simple authentication. Sets the PROVIDER_URL to the MDS host and port. Sets the INTITIAL CONTEXT FACTORY.

Parameters:

host - the hostname of the machine on which a GRIS or GIIS is running.

port - the Port number on which a GRIS or GIIS is running.

Method Detail

setLdapConnectionEnv

public void setLdapConnectionEnv(String index,
                                 String value)

Enables a user to set new or overide existing connection settings to the MDS.

Parameters:

index - Holds the index string for the connection environment.

value - Holds the value corresponding to the index fro the connnection environment.

setLdapSearchConstraints

public void setLdapSearchConstraints()

connectMds

                       throws NamingException

Create and return a MDS LdapContext.

Returns:

LdapContext

Throws:

NamingException

searchMDS

public NamingEnumeration searchMDS(LdapContext mdsctx,
                                   String baseDN,
                                   String filter)

Still Thinking how to eable this option.
