FAQ
I am having a problem adding filerLists to my scans. These are the standard
filters, nothing custom. When I use them on the client, I get the following
errors. Maybe I need to include some additional jars on my classpath? I am
using row filters in the filter list.

pseudo-ish code:

Scan s = new Scan();
FilterList fl = new
FilterList(FilterList.Operator.MUST_PASS_ALL){addFilter(new
RowFilter(CompareFilter.CompareOp.NOT_EQUAL, new
SubstringComparator("|something|")));addFilter(new
RowFilter(CompareFilter.CompareOp.NOT_EQUAL, new
SubstringComparator("|somethingelse|")));}
s.setFilter(fl);

    Hi Barney,

    I think the clever syntax you're using might be confusing things.

    Try:
    FilterList fl = new FilterList(FilterList.Operator.MUST_PASS_ALL);
    fl.addFilter(...);
    fl.addFilter(...);
    s.setFilter(fl);

    When you use the {...} trick, you're making an anonymous subclass of
    FilterList which doesn't exist on the server-side.

    Yes, that was it. My scans are now back on the fast track. Thanks!
