> The QueryParser are to restrictive when validating a query expression.
> It is not possible to use a hash sign (#) in a String literal query expression.
> An IllegalArgumentException are thrown for this query:
> String ejbql = "SELECT s FROM Service s WHERE s.name = 'DB#CORE' ";
> Query q = em.createQuery(ejbql);
> Rather than using:
>       StringTokenizer tokens = new StringTokenizer(ejbql, "#}", true);
> it would be better to be more precise in selecting what should be processed, use regexp and splitting the ejbql expression for #{...} instead.
> Exception stacktrace:
> java.lang.IllegalArgumentException: missing { after # in query fragment
