Subject [Jackrabbit Wiki] Update of "ExamplesPage" by amallogia
Date Tue, 15 Feb 2011 16:27:37 GMT
Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Jackrabbit Wiki" for change notification.

The "ExamplesPage" page has been changed by amallogia.

--------------------------------------------------

  == Apache Jackrabbit Examples ==
+ This page will be used to show solutions to common problems related to Apache Jackrabbit
and the JCR API. These examples shouldn't be considered Best Practices - general error checking
and exception handling have been omitted to keep the example code simple.

  == Spring Configuration ==

  You can create a Repository reference in Spring in multiple ways, but here's one that uses
the RepositoryImpl class:
  
  {{{
      <bean id="repository" class="org.apache.jackrabbit.core.RepositoryImpl">
          <constructor-arg index="0" ref="config" />
      </bean>
-     <bean id="config" class="org.apache.jackrabbit.core.config.RepositoryConfig" factory-method="create">
       
+     <bean id="config" class="org.apache.jackrabbit.core.config.RepositoryConfig" factory-method="create">
          <constructor-arg index="0" value="./repository.xml"/>
          <constructor-arg index="1" value="." />
      </bean>
  }}}
- 
  This will create a repository in the current directory, using ./repository.xml as the configuration
file. This isn't as complete as se-jcr will be (hopefully) but this does work with Spring
3.0 and JackRabbit 2.0.
