Hi ,

I took the current build from the trunk . A new error has crept in and am unable to configure any Oracle Spatial Layers.It was working fine with yesterday’s build.

java:151)

This error is logged but it's not fatal, it's GWC crashing because
it cannot handle the events GeoServer trunk throw miss some
information it needs.
We added a try/catch around the even throwing code that just logs
the exception, as you can see here:

> 15 Apr 10:37:49 WARN [catalog.imp] - Catalog listener threw exception
> handling e
> vent.

the code dealing with events being:

protected void event(CatalogEvent event) {
         for (Iterator l = listeners.iterator(); l.hasNext():wink: {
             try {
                 CatalogListener listener = (CatalogListener) l.next();
                 if (event instanceof CatalogAddEvent) {
                     listener.handleAddEvent((CatalogAddEvent) event);
                 } else if (event instanceof CatalogRemoveEvent) {
                     listener.handleRemoveEvent((CatalogRemoveEvent) event);
                 } else if (event instanceof CatalogModifyEvent) {
                     listener.handleModifyEvent((CatalogModifyEvent) event);
                 } else if (event instanceof CatalogPostModifyEvent) {
listener.handlePostModifyEvent((CatalogPostModifyEvent)event);
                 }
             } catch(Exception e) {
                 LOGGER.log(Level.WARNING, "Catalog listener threw exception handling event.", e);
             }

         }
     }

Soo... you're probably looking at the wrong stack trace?
Cheers
