[ http://issues.apache.org/jira/browse/DIGESTER-29?page=comments#action_12449528 ] Craig McClanahan commented on DIGESTER-29: ------------------------------------------
Besides 1.5 (the documented "Affected Version"), this issue is also present in version 1.6 and 1.7. It bit me when I was using the Digester.register() method to register copies of DTDs internal to the JAR file. This would cause an I/O stream or something to remain open on the DTD, which (in turn) would cause the jar file to remain locked after a webapp undeploy on Windows. Happily, the patched version works fine for this scenario (tested with the 20061111 nightly build), so I guess it's time to get back in the digester game and help get a 1.8 release out the door :-). > [digester] Loading of resources causes webapp to fail redeploy under Tomcat > 5.5.x > --------------------------------------------------------------------------------- > > Key: DIGESTER-29 > URL: http://issues.apache.org/jira/browse/DIGESTER-29 > Project: Commons Digester > Issue Type: Bug > Affects Versions: 1.5 Final > Environment: Operating System: other > Platform: Other > Reporter: Rich Feit > Attachments: bug37034-fix.txt, strutsRedeploy.zip > > > This was originally filed against Beehive as > http://issues.apache.org/jira/browse/BEEHIVE-960 , but I've narrowed it down > to > either a Digester issue or a Tomcat issue.
