Problem running Undeploy Target in Tomcat 5.5.9

[untz <un...@yahoo.com>]

Hello there,

I am using JDK 1.5, Eclipse 3.2, and Tomcat 5.5.9. I wrote a build script which compiles, packages (via war file) the source, deploys (moves the war into TOMCAT_HOME/webapps), and is supposed to undeploy (by deleting the particular web app's directory & war file under TOMCAT_HOME/webapps).

The problem that I am encountering is that while Tomcat is running, I have a lib directory: TOMCAT_HOME/MyWebApp/WEB-INF/lib which contains several needed jar files. It seems that when I run my Ant's undeploy target, it refuses to delete the lib directory and thus the build breaks:

Buildfile: C:\DevProjects\guess_number\build.xml
undeploy:
   [delete] Deleting directory C:\DevTools\tomcat\jakarta-tomcat-5.5.9\webapps\NumberGuess

BUILD FAILED
C:\DevProjects\guess_number\build.xml:57: Unable to delete file C:\DevTools\tomcat\jakarta-tomcat-5.5.9\webapps\NumberGuess\WEB-INF\lib\Echo2_App.jar

build.properties:

project.name=NumberGuess
build.dir=./build

# Webapp properties for the project
webapp.name=NumberGuess
webapp.build.dir=${build.dir}/${webapp.name}
webapp.virtual.host=localhost

# Tomcat properties
tomcat.home=C:/DevTools/tomcat/jakarta-tomcat-5.5.9
tomcat.deployment.dir=${tomcat.home}/webapps

When I manually shutdown Tomcat, I am able to run my undeploy target just fine... But I need it to be able to undeploy while Tomcat is running.

Many, many thanks!

Means there are files in use; tomcat has the files open and you cannot 
delete them.

Switching to unix will fix this, but not much else
