Setting value is multi values property through java code

Hi,

I am trying to set values to one string[] multi valued property in the CQ page.  i am doing it through remote java application not in CQ environment.

Here is the code that i am using

Value[] values = new Value[10];

values[0] = session.getValueFactory().createValue("NewValue-one");

  values[1] = session.getValueFactory().createValue("NewValue-two");

while(nodeIter.hasNext())

{

Node myNode= nodeIter.nextNode();

myNode.getName();

myNode.setProperty("cq:tags", values);

}

I am not getting any exceptions while setting the property but after setting the values to the property, i looked into the properties tab in the CRXDE and i am seeing the values are not set and it's empty.

Here is the screenshot of properties tab in the CRXDE

Can someone help me on this? Let me know if you need anymore info.

In  myNode.setProperty("cq:tags", values); values has to be String[] and save session.

myNode.getSession().save();

    That is correct - you need to use an array.

    I agree with you. But In my case i am setting value to the "cq:tags" property.  whenever i am setting the values using the above code, the value becomes empty in the cq:tags property.

    Do we need to do in a different way to set multivalue to the property cq:tags?

    Edit :- Correcting my answer

    Arun,

         Could you please check if the tags you are trying to set is already present under /etc/tags ? If not your values will never set to cq:tags property

    Thanks

      Hi Scott.

           We cannot set tags as normal properties. Those needs to be handled using TagManager API

      Can you please confirm that your tags are already created before saving in cq:tags property. Properties will not save if tags are not present.

      or you can also use tagManager api to set tags

      void setTags(Resource resource, Tag[] tags)

      void setTags(Resource resource, Tag[] tags,boolean autoSave)

      I will check that . Before doing that i am trying to access tag manager api but can't get access to getTagManager method.

      I can't able to call get TagManager method using the JCRTAG manager resolver factory. It's throwing me error. Here is my code

      JcrTagManagerFactory.getTagManager(session); //throwing compile time error

      Hi Arun

           For tag related operations, you should use tag manager API TagManager ("The Adobe AEM Quickstart and Web Application.") 

      To get a TagManager object , you can do the following

      Please refer sample codes to work with TagManagers here Java Code Example com.day.cq.tagging.TagManager

      Java Code Example com.day.cq.tagging.TagManager

      Thanks

      Hey Guys,

      Thanks for your valuable information. It was very helpful. At-last i found solution to my problem. I am connecting CQ remotely through my java code and i am not using Sling or OSGI . Because my application is not running in any of the CQ servers and it's running remotely in apache tomcat server. So i am using only JCR api to connect to CQ server and modifying the contents. Here is the code which used for tagging.

      Node jcrNode=session.getNode("/etc/tags/default");

      Node my_casecustom=jcrNode.addNode("my_casecustom","cq:Tag");

      jcrNode.addMixin("mix:referenceable");

      session.refresh(true);

          session.save();

          my_casecustom.setProperty("jcr:title", "custom,my case");

          my_casecustom.setProperty("jcr:title.en_us", "custom,my case");

          my_casecustom.setProperty("sling:resourceType", "cq/tagging/components/tag");

      session.refresh(true);

          session.save();

      After i added CQ:TAGS property into my pagecontent node and it's settings the values to corresponding node.
