Subject [jira] Created: (AMQ-2536) XPath selectors return false if xalan is not on the classpath
Date Thu, 17 Dec 2009 13:36:00 GMT
XPath selectors return false if xalan is not on the classpath
-------------------------------------------------------------

                 Key: AMQ-2536
                 URL: https://issues.apache.org/activemq/browse/AMQ-2536
             Project: ActiveMQ
          Issue Type: Bug
          Components: Selector
    Affects Versions: 5.3.0
            Reporter: Roman Kalukiewicz


When xalan.jar is not on the classpath, then {{org.apache.activemq.filter.XalanXPathEvaluator}}
in {{evaluate()}} method tries to load {{org.apache.xpath.CachedXPathAPI}}, throws {{NoClassDefFoundError}},
that is catched as {{Throwable}} and {{false}} is returned instead of an error.

No clue is given to the client, that it lacks a jar on the classpath and the impression is,
that XPath selectors doesn't work and return false whatever the message is.

I believe if we catch {{Exception}} instead of {{Throwable}}, then the problem would be fixed.
