Hi. Any help would be much appreciated on this problem, which has appeared
since catalina 5.5.12. (WinXP SP2, Sun JDK 1.5.0_06, Eclipse 3.2M4)
As part of my startup routine, my first servlet reconfigures logging:
Logger.getRootLogger().removeAllAppenders();
DOMConfigurator.configure(logElement);
Where logElement defines a new set of appenders. I do it like this so
I can redirect the tomcat log output, in addition to mine, to a single
set of appenders, which has proven very useful as this all runs on a
remote server. This may or may not be a stupid thing to do, but it
has worked fine up to 5.5.15.
Catalina boots correctly when started up, but when the context
(as \conf\Catalina\localhost\ROOT.xml) is hot-redepoyed from Eclipse
using the ant tasks in catalina-ant.jar like this:
<tomcat_undeploy username="manager" password="password" path="/" />
[...]
<tomcat_install username="manager" password="password" path="/"
config="file:/dev/sitemanager/resources/catalina_home/conf/Catalina/localhost/ROOT.xml" />
I get the following exception:
log4j:ERROR Error occured while converting date.

Any ideas would be appreciated - this has made development a real pain.
