58. Why use the boostrap port number?
client applications use the bootstrap port to access websphere’s built-in object request broker (orb) to use enterprise java beans in applications installed on the application server. The java naming and directory interface service provider url used by the client application needs to reference the bootstrap port to obtain an initial context for looking up ejb’s it wants to use. (For communicate two servers)
59. What are the appserver components?
admin server, web container, ejb container,j2c service, naming server, messaging engine, security server.
