Re: exception error code

5 Feb 2002 17:46:30 -0000

I've created the collection and added a few documents.  I've queried the collection from the command line and get the right results.  I'm no trying to do the same thing from a Java program to get to grips with the XML:DB Api.  The code I'm using is below.  Any ideas where I'm going wrong will be gratefully received.
 
Cheers

public class ConnectToDbxml {
 
    /**  */
    public static void main(String args[]) throws Exception {
       
        Collection col = null;
       
        try{
            String driver = "org.dbxml.client.xmldb.DatabaseImpl";
            Class c = Class.forName(driver);
       
            Database database = (Database)c.newInstance();
            DatabaseManager.registerDatabase(database);
           
            col = DatabaseManager.getCollection("xmldb:xindice:///db/myexamples");
       
            String xpath = "/person";
            XPathQueryService service = (XPathQueryService)col.getService("XPathQueryService", "1.0");
           
            ResourceSet resultSet = service.query(xpath);
           
            ResourceIterator results = resultSet.getIterator();
            while(results.hasMoreResources()){
                Resource res = results.nextResource();
                System.out.println((String)res.getContent());
            }
        }
        catch (XMLDBException e) {
            System.err.println("XML:DB Exception occured " + e.errorCode);
        }
        finally {
            if (col != null) {
                col.close();
            }
        }
    }

It means something didn't work :-).   I don't mean that in a bad way,
I think you get that error for many different types of problems.

Have you created the collection "myexamples"?

Try

dbxmladmin lc -c /db

It should list your collections.

Try "getting" one of the ones that are in the list.

HTH,
