Manger remove of context deployed as defult webapp gets NPE
Summary: Manger remove of context deployed as defult webapp gets
NPE
Product: Tomcat 4
Version: 4.1.27
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: Other
Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: gabriele.garuglieri@infoblu.it
I install a default webapp with manager install command using a context descriptor.
<Host> is defined with unpackWARs="false" autoDeploy="true" liveDeploy="false".
If i install with
<Context path="" docBase="C:\home\cvshome\ivnext-2.3\build/ant-build/infoviabilita"
ie the docBase points to a directory, when i launch remove command with
parameter path=/ i get the following:
2003-09-19 10:22:57 Manager: remove: Removing web application at '/'
2003-09-19 10:22:57 StandardHost[localhost]: Removing web application at context
path
In this case neither context.xml nor the app dir are in the webapps dir.
If i install with
<Context path="" docBase="infoviabilita.war" with both context.xml and war into
webapps dir, when i launch remove command with parameter path=/ i get the following:
2003-09-19 10:24:32 Manager: remove: Removing web application at '/'
2003-09-19 10:24:32 StandardHost[localhost]: Removing web application at context
path
2003-09-19 10:24:32 StandardHost[localhost]: Error removing application at
context path

After this i find that the context is removed, but neither context.xml nor war
file are removed from webapps dir.
By the way, in the doc it says that if path parameter referes to the default
webapp it must be a "zero length string", but if i specify path= i get "Invalid
context path was specified".
