Hi,
I followed Marc's method but it never goes to pre section if it is already installed.

Install the exploded webapp to a fixed directory structure. For instance,
our web tracking goes in /bms/webapp/webtrk with WEB-INF META-INF
subdirs and maybe an art subdir, etc. (If Linux Standards Base ever
addresses the issue, it would probably belong in /usr/share/java-webapp
or /var/lib/java-webapp instead.)
Then add a symlink to your webapp container, for instance with JPP packaged
tomcat5, add /var/lib/tomcat5/webapp/webtrk -> /bms/webapp/webtrk
I also find it handy to symlink WEB-INF/classes -> /bms/java where the webapp
and additional RPMs drop class files for our local java packages (so that the
web app is composed of multiple versioned RPMs). To enable this symlink,
the RPM needs to also install META-INF/context.xml with something like:
<?xml version="1.0" encoding="UTF-8"?>
<Context allowLinking="true">
<!-- Default set of monitored resources -->
<WatchedResource>WEB-INF/web.xml</WatchedResource>
<!-- Uncomment this to disable session persistence across Tomcat restarts -->
<!--
<Manager pathname="" />
-->
</Context>
