Hello,
I encounter an issue on redeploy ( ie undeploy/deploy a web archive)
I use jakarta ant task on windows XP and tomcat 5.5.9 to deploy the web 
archive. The ant task undeploy/deploy the application.
I also use sometime the undeploy link of tomcat manager which produce also the 
same error.
Does anyone encounter this on windows platform ? And was able to fix it ?


The produced error is :

<code>
