Subject Problem with redeploying webapp in tomcat
Date Fri, 11 Aug 2006 07:35:43 GMT
Hello All,

We have an automated script that builds our webapp
(.war file) and deploys this app on our remote
webserver, using the remove and install facilities
provided by tomcat manager. We run this script daily
at a particular scheduled time.

The script creates the application war file, send the
war to the remote server via ftp and then redeploy's
the webapp using ant targets:

<get
src="${app.deploy.manageurl}/stop?path=${app.deploy.path}"
dest="${LOG4J_LOGFILE}" username="${tomcat.user.name}"
password="${tomcat.user.password}"/>   --- First stop
the previous running app

<get
src="${app.deploy.manageurl}/remove?path=${app.deploy.path}"
dest="${LOG4J_LOGFILE}" username="${tomcat.user.name}"
password="${tomcat.user.password}"/>   ---
Remove/uninstall the webapp

<get
src="${app.deploy.manageurl}/install?path=${app.deploy.path}&amp;war=jar:file:${ftp.absolutedir.loc}/${core.war}!/"
dest="${LOG4J_LOGFILE}" username="${tomcat.user.name}"
password="${tomcat.user.password}"/>   --- Install
from the war file sent over ftp


My problem is that - This process went fine for a few
days, but now I'm getting OutOfMemoryException when
performing this process on tomcat server. I've pasted
the stack trace of the exception below:

Can anybody help me and let me know why am I getting
this OutOfMemory Exception, and how to fix this
exception?

Thank you,
Venkatesh
