Hi there,

In my application I have this method:

public static String getAllPartsAsTree(String a) throws XQException, XQQueryException
    {
        XQConnection con = Connection.getConnection();
        XQExpression xqe = con.createExpression();

        xqe.bindString(new QName("b"), a, null);

        String xqueryString =
                "import module namespace lib=\"http://www.example.com/library_module\";" +
                "declare option output:method \"xhtml\";" +
                "declare variable $b external; " +
                "lib:gethtml($b)";

        XQResultSequence rs = xqe.executeQuery(xqueryString)

;

        String b = rs.getSequenceAsString(null);

        con.close();

        return b;
    }

When I run the app I get the following error message:

Exception in thread "main" javax.xml.xquery.XQException: The prefix "output" is unknown in this static context.

I can't understand how to interpret the error message.
The same query in BaseXGUI works perfectly.
I hope someone can help me.
Thanks!
