Subject Search by an inputstream property
Date Mon, 16 Jul 2012 18:51:28 GMT
Hi friends, i have a question about making a xpath expression for 
filtering resources by a property of type inputStream called data.
How i can do a text search... for example... this is working:

String xpath1 = "<my app path>//element(*, nt:resource) 
[jcr:contains(@jcr:mimeType,'*plain*')]";
String xpath2 = "<my app path>//element(*, nt:resource) 
[jcr:contains(@jcr:encoding,'*utf*')]";

But this is not working....
String xpath3 = "<my app path>//element(*, nt:resource) 
[jcr:contains(@jcr:data,'*plain*')]";

The really fact is that we use some custom nodes.. let's explain the 
properties definitions:

In Java Terms...

|public class*Resource*extends BaseNode {
||
   /** Encoding media type. It cannot be null or empty. */
   @Field(jcrName = "jcr:encoding", jcrDefaultValue = "")
   private String encoding;|
|
   /** Resource's MIME type. It cannot be null or empty. */
   @Field(jcrName="jcr:mimeType", jcrDefaultValue = "")
   private String mimeType;

   /** Resource's size (bytes). */
   @Field(jcrName="skl:size")
   private long size;

   /** Resource's content data as stream. It cannot be null. */
   @Field(jcrName="jcr:data")
   private InputStream data;

   ...
}

||@Node(jcrType = "baseNode", isAbstract = true)
public abstract class*BaseNode*{

   @Field(jcrName = "name", id = true)
   protected String name;

   @Field(jcrName = "creationDate")
   protected Date creationDate;

   ...
}|

And in JackRabbit Terms...

                         multiple="false" />
   </nodeType>

The point is.. how i do this query... in order to filter by jcr:data 
property...
Thanks for advance, and for reading this!
Greetings.
