public class Server

extends java.lang.Object

This class provides utility methods for obtaining EJB Home references, and for manipulating remote objects and enumerations. This class can cache EJB Home interfaces if the ejb.cacheHomes=true setting is specified in BankframeResource.properties. If homes caching is defined then the Homes cache must be configured in BankframeResource.properties as follows:

 cache.homesCache.class=com.bankframe.services.cache.GenericCache
 cache.homesCache.policy=com.bankframe.services.cache.LruCachePolicy
 cache.homesCache.policy.maxSize=100
 cache.homesCache.policy.thrashAmount=10
