|Oracle GlassFish Server Message Queue 4.5 Administration Guide|
Administered objects are placed in a readily available object store where they can be accessed by client applications by means of the Java Naming and Directory Interface (JNDI). There are two types of object store you can use: a standard Lightweight Directory Access Protocol (LDAP) directory server or a directory in the local file system.
An LDAP server is the recommended object store for production messaging systems. LDAP servers are designed for use in distributed systems and provide security features that are useful in production environments.
LDAP implementations are available from a number of vendors. To manage an object store on an LDAP server with Message Queue administration tools, you may first need to configure the server to store Java objects and perform JNDI lookups; see the documentation provided with your LDAP implementation for details.
To use an LDAP server as your object store, you must specify the attributes shown in Table 11-1. These attributes fall into the following categories:
Security. The java.naming.security.principal, java.naming.security.credentials, and java.naming.security.authentication attributes govern the authentication of callers attempting to access the object store. The exact format and values of these attributes depend on the LDAP service provider; see the documentation provided with your LDAP implementation for details and to determine whether security information is required on all operations or only on those that change the stored data.

Message Queue also supports the use of a directory in the local file system as an object store for administered objects. While this approach is not recommended for production systems, it has the advantage of being very easy to use in development environments. Note, however, that for a directory to be used as a centralized object store for clients deployed across multiple computer nodes, all of those clients must have access to the directory. In addition, any user with access to the directory can use Message Queue administration tools to create and manage administered objects.
To use a file-system directory as your object store, you must specify the attributes shown in Table 11-2. These attributes have the same general meanings described above for LDAP object stores; in particular, the java.naming.provider.url attribute specifies the directory path of the directory holding the object store. This directory must exist and have the proper access permissions for the user of Message Queue administration tools as well as the users of the client applications that will access the store.
