Subject XPATH search with Excerpt via DavEx
Date Tue, 29 Jun 2010 13:32:19 GMT
dear all,

I am using Jackrabbit JCR via DavEx (not RMI) and would like to do an 
fulltext-search xpath query including excerpt of the found text parts.
I am using the following code to do a fulltext search query for term 
"jackrabbit":

----------------------------------------- test function start 
------------------------------------
     public void doFulltextSearchTest() {
         try {
             System.out.println("found:");
             RowIterator rows = queryFulltextSearch("kanzlei");
             for (RowIterator it = rows; it.hasNext();) {
                 Row r = it.nextRow();
                 Value title = r.getValue("Title");
                 Value excerpt = r.getValue("rep:excerpt(.)");
                 System.out.println("Element title:" + title + " excerpt"
                         + excerpt);
             }
         } catch (ItemNotFoundException e) {
             e.printStackTrace();
         } catch (RepositoryException e) {
             e.printStackTrace();
         }

     }


     public RowIterator queryFulltextSearch(String searchstring) throws 
RepositoryException{
          QueryManager qm = currentSession.getWorkspace().getQueryManager();
          Query q = qm.createQuery("//*[jcr:contains(., 
'"+searchstring+"')]/(@Title|rep:excerpt(.))", Query.XPATH);
          QueryResult result = q.execute();
          return result.getRows();
      }
----------------------------------------- test function 
end------------------------------------

---------------------------- causes Exception start 
--------------------------------------
javax.jcr.ItemNotFoundException: rep:excerpt(.)

org.apache.jackrabbit.jcr2spi.query.RowIteratorImpl$RowImpl.getValue(RowIteratorImpl.java:271)
     at 
consearch.demos.jcr.FulltextSearchTest.<init>(FulltextSearchTest.java:44)
     at 
consearch.demos.jcr.FulltextSearchTest.main(FulltextSearchTest.java:61)
---------------------------- causes Exception end 
--------------------------------------

Is it possible to arrange this via DavEX and how?
thanking you in advance for helping me

best regards, Thomas
