OpenSAML user discussion

["Peter Gambino" <>]

This may be my confusion then.  I know that we use Xerces2 - Date on our
xercesImpl Jar is around 5/2006...   Your Jar was date was older In our app
we receive this:

java.lang.AbstractMethodError:
javax.xml.parsers.DocumentBuilderFactory.setFeature(Ljava/lang/String;Z)V
        at org.opensaml.XML$ParserPool.<init>(XML.java:490)
        at org.opensaml.XML.<clinit>(XML.java:118)
        at org.opensaml.SAMLRequest.<init>(SAMLRequest.java:122)

            dbf = DocumentBuilderFactory.newInstance();
            dbf.setNamespaceAware(true);
            try {
>>ERROR HERE:
dbf.setFeature("http://apache.org/xml/features/validation/schema/normalized-
value",false);
                        } catch (Throwable e) {
                                log.warn("Unable to turn off data
normalization in parser, supersignatures may fail with Xerces-J: " + e);
                        }
            registerSchemas(null);

>From all the docs I read, it is because NewInstance fails.  I took our
xercesImpl jar and plugged it in to the endorsed directory in my opensaml
directory and received the same errors in the unit tests.  That's why I was
going down the road of a xerces version issue.

There are no versions of OpenSAML that use Xerces 1.x. The code itself is
not Xerces-dependent at all, it *requires* JAXP 1.3. That goes for
stable/old and the unreleased version in development.

The common thread is that the only usable JAXP 1.3 parser we know is Xerces
2.x, so in practice it requires that. Could be that other parsers will work,
but Sun's won't.

So, basically, you're confused in some way. Whatever the disparity is, it
sure isn't the Xerces version.
