spi2dav: rep:excerpt() does not work

When using Jackrabbit JCR via DavEx (not RMI) and doing an fulltext-search xpath query including excerpt of the found text parts.

I am using the following code to test 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(.)

at consearch.demos.jcr.FulltextSearchTest.main(FulltextSearchTest.java:61)
---------------------------- causes Exception end --------------------------------------

I guess that excerpt is a major feature when getting WebDav in a full featured state
