How to Retrieve the Actual Content from a Alfresco NodeRef

[partha]

Hi,
     I executed the search query based on the folder structure i have in my alfresco and i got a list of NodeRef object as a result of the query execution.

     For each NodeRef object i tried to retrieve the content using NodeService as below
            nodeService.getProperty(nodeRef, CMSModelConstants.CONTENT_PROP_QNAME);
     Constant mentioned is a Qname for cm:content, and the resule i got is
            contentUrl=store://2008/4/21/13/41/e6554862-0f97-11dd-9c3b-61b22a66865f.bin|mimetype=text/plain|size=24|encoding=UTF-8

      Can any one tell me how i can take the actual content of the NodeRef object which actually points to either a ".txt or .doc or .pdf etc." file.

Thanks
Partha.

ContentReader contentReader = contentService.getReader(nodeRef, ContentModel.PROP_CONTENT);

Hi,
    Thanks Janv.

    I used the following code as you mentioned.
     ContentReader contentReader = contentService.getReader(nodeRef, ContentModel.PROP_CONTENT);
      contentReader.getContentString();

Its returning the content for text files properly but for pdf files its not returning properly. It gives lot of junk characters.
How to handle for pdf files.

PDF is a binary format.

ContentReader contentReader = contentService.getReader(nodeRef, ContentModel.PROP_CONTENT);
InputStream is = contentReader.getContentInputStream();

How can I initialize contentService variable inside an ActionExecuter??

Thanks, any help is appreciated

[janv]

Refer to http://wiki.alfresco.com/wiki/Custom_Actions

You can inject it in, by creating your own alfresco/extension/custom-action-services-context.xml

  ….
  <bean id="myAction" class="org.my.executer.MyActionExecuter" parent="action-executer">
        <property name="contentService">
            <ref bean="ContentService" />
        </property>
  </bean>
  ….

Hi!!
I make this changes in my code:

1) I updated the alfresco/extension/parse-action-context.xml

…
<beans>
      
    <!– Parse Action Bean –>
    <bean id="parse-action" class="org.alfresco.sample.ParseActionExecuter" parent="action-executer" >
       <property name="contentService">
            <ref bean="ContentService" />
        </property>
     </bean> 
…‍‍‍‍‍‍‍‍‍‍

2) I updated my code in the action executer (ParseActionExecuter.java)

…
        ContentService contentService;
        ContentReader contentReader = contentService.getReader(actionedUponNodeRef, ContentModel.PROP_CONTENT);
        InputStream is = contentReader.getContentInputStream();
        BufferedReader br= new BufferedReader(new InputStreamReader (is));
        …‍‍‍‍‍‍

but in   contentService.getReader(…) I get error ("the local variable contentService may not have been inizialized")

Where I make mistakes??

Thanks for reply and helping me!!
