  • For List, Set, Map collection we use <list>, <set>, and <map> tags.
  • We have to define List, Set, Map interface to use these tags.
  • * Default it will create ArrayList for list, LinkedHashSet for set and LinkedHashMap for map tag.
<bean id="" class="">
	<property name="">

Create Java Project

  • Open Eclipse
  • Go to File -> New -> Others… -> Java Project
  • Create DI-DefaultCollection project
  • Right click on project -> Build Path -> Configure Build Path -> Libraries tab -> Add External JARs
    • commons-logging-X.X.jar
    • spring-beans-X.X.X.jar
    • spring-context-X.X.X.jar
    • spring-core-X.X.X.jar
    • spring-expression-X.X.X.jar
  • * You can find dtd information from spring-beans-X.X.X.jar -> org -> springframework -> beans -> factory -> xml -> spring-beans.dtd (line no 36 & 37)
