  14. Elementejb-name specifies the name of this bean. Elementweblogic-ejb-jar contains deployment information for all EJBs in the EJB JAR. Elementweblogic-enterprise-bean contains deployment information for the Customer EJB. Elementmac-beans-in-cache defines the maximum number of active instances the container should allow. Elementcache-strategy sets how EJBs should cache data. Elementpersistence-descriptor defines the EJBs persistence properties. Elementpersistence-type contains the elements type-identifier, which must be WebLogic_CMP_RDBMS. Elementtype-storage specifies the location of the CMP descriptor. Contain the descriptions of caching properties Specify the DTD for the descriptor. 1 <?xml version = "1.0" encoding = "UTF-8"?> 2 3 <!-- weblogic-ejb-jar.xml deployment descriptor for bookstore --> 4 <!-- describes weblogic specific properties of each bean --> 5 6 <!DOCTYPE weblogic-ejb-jar PUBLIC 7 '-//BEA Systems, Inc.//DTD WebLogic 5.1.0 EJB//EN' 8 'http://www.bea.com/servers/wls510/dtd/weblogic-ejb-jar.dtd'> 9 10 <!-- Customer EJB weblogic descriptor --> 11 <weblogic-ejb-jar> 12 13 <weblogic-enterprise-bean> 14 <ejb-name>Customer</ejb-name> 15 16 <!-- determines caching properties --> 17 <caching-descriptor> 18 <max-beans-in-cache>100</max-beans-in-cache> 19 <cache-strategy>Read-Write</cache-strategy> 20 <read-timeout-seconds>0</read-timeout-seconds> 21 </caching-descriptor> 22 23 <!-- maps cmp types for bean --> 24 <persistence-descriptor> 25 26 <persistence-type> 27 <type-identifier> 28 WebLogic_CMP_RDBMS 29 </type-identifier> 30 <type-version>5.1.0</type-version> 31 <type-storage> 32 META-INF/weblogic-cmp-rdbms-jar-Customer.xml 33 </type-storage> 34 </persistence-type> 35 Fig. 21.4 Weblogic-ejb-jar.xml defines WebLogic deployment properties for Bookstore case study.Lines 6-8Lines 11-356Lines 13-71Line 14Lines 17-21Line 18Line 19Lines 24-42Lines 26-34Lines 27-29Lines 31-33
