reading Alfresco Repository (ALF_DATA), by JackRabbit

[fthamura]

I want to read Alfresco Data using Jackrabbit

anyone have experience, or any JCR api, so I can query the files inside.

[davidc]

The simple way is to use Alfresco.

[bindiya]

I have accessed contents and spaces of Alfresco using JackRabbit. If your are interested to look at my code, let me know.

[nimind]

please, i'm very interested.  I am trying to use WEBDAV but i can not get something. If you can help… much thanks!!!!!!!!!!

[bindiya]

This is works with WEBDAV client RMI for jboss.
alfresco server running in port 8080
Remote Jboss server running in 9080
jackrabbit-server RMI port is 3099 (modified web.xml for jackrabbit-server-1.1.war , details given below)


JCR-RMI Configuration

Stop alfresco server. Do the configuration as mentioned in http://wiki.apache.org/jackrabbit/JackrabbitOnJBoss

1.   Download jackrabbit-jca-1.1.rar.
2.   Copy “jcr-1.0.jar” from the above rar to < ALFRESCO >/server/default/lib folder. Delete this jar from jackrabbit-jca-1.1.rar.
3.   Deploy jackrabbit-jca-1.1.rar to <ALFRESCO>/server/default/deploy .
4.   Download jcr-ds.xml and deploy this to ALFRESCO>/server/default/deploy. (jcr-ds.xml  is pasted below)
5.   Modify jcr-ds.xml,                            <rar-name> jackrabbit-jca-1.1.rar </rar-name>                                                    Change configuration properties-                        (Example - <config-property name="homeDir">/Apps/ALFRESCO/alfresco-community-jboss-1.4.0/jboss/server/default/data/jcr</config-property>                  <config-property name="configFile"> /Apps/ALFRESCO/alfresco-community-jboss-1.4.0/jboss/server/default/data/portal/cms/conf/repository.xml</config-property>)                         (Note – “homeDir ”- Location to create content repository                   “configFile”- Location of repository.xml file . )





•   Deploy “jackrabbit-server-1.1.war” in <ALFRESCO>/server/default/deploy.

•   Modify  “jboss-service.xml” in <ALFRESCO>/server/default/conf as follows (use jboss-log4j.xml it is pasted below.)

<mbean code="org.jboss.logging.Log4jService"
      name="jboss.system:type=Log4jService,service=Logging"
     xmbean-dd="resource:xmdesc/Log4jService-xmbean.xml">
      <attribute name="ConfigurationURL">resource:jboss-log4j.xml</attribute>
      <!– Set the org.apache.log4j.helpers.LogLog.setQuiteMode. As of log4j1.2.8
      this needs to be set to avoid a possible deadlock on exception at the
      appender level. See bug#696819.
      –>
      <attribute name="Log4jQuietMode">true</attribute>
      <!– How frequently in seconds the ConfigurationURL is checked for changes –>
      <attribute name="RefreshPeriod">60</attribute>
   </mbean>

•   Delete “log4j.xml” from <ALFRESCO>/server/default/conf

a lot of thanks! My problem was a mistake in the xml and the code that i don't know how to connect.
If you need something, i would like to help you

[bindiya]

no problem.
Do you know how to access repository programmaticlly within alresco.war?
I need to modify a jsp page within afresco.war and write code which would access repository. I tried using codes of FirstJCRClent. , but no luck.

It would be great if i get this working.

Thanks,
Bindiya
