Subject [jira] Commented: (ODE-223) BPEL process using bpws:doXslTransform(...) crash at tomcat restart
Date Fri, 11 Jan 2008 21:48:35 GMT

    [ https://issues.apache.org/jira/browse/ODE-223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12558141#action_12558141
] 

Sebastian Mosser commented on ODE-223:
--------------------------------------

At all, no other version of Saxon (I've never heard that name !).

If it's specific to my environment, it's not a problem, I've just added a rm -rf *.deployed
at tomcat startup. But it's ... weird.

using xsl stylesheet has the same weird behaviour) (invoke.sh is basically a 'curl | xmllint
--format -' script)
