Xpath Query Problem

[Avik Chatterjee]

Hi,
I have been using the following code for xindice1.1b1 to check a 
collection..

col = 
DatabaseManager.getCollection("xmldb:"+administration.Host.getXindiceType()+"://"+hostPort+"/db/"+context+"/forums/gdCollection");

            String xpath = "//forumid[contains(string(),'"+forumName+"')]" 
;

            XPathQueryService service =
               (XPathQueryService) col.getService("XPathQueryService", 
"1.0");
            ResourceSet resultSet = service.query(xpath);
            ResourceIterator results = resultSet.getIterator();

now after i compiled in Xindice1.1b2 and execute the code, following error 
occurs..

java.lang.NoSuchMethodError: org.apache.xpath.compiler.OpMap.getOpMap()[I
