unable to change context path

the context path is actual set to /jira - I wolould like to set it to /jira-test but the system does not get up.
the context path is only set in the server.xml:

<Context path="/jira-test" docBase="/var/apphome/jira/catalina_base/webapps/jira/">
<Resource name="UserTransaction" auth="Container" type="javax.transaction.UserTransaction"
factory="org.objectweb.jotm.UserTransactionFactory" jotm.timeout="60"/>
<Manager pathname=""/>
</Context>

When I set the context path back to /jira it will work again.
