Question

I’m following spring tutorial . In that it control tomcat with ant tasks. Earlier I face few problems because of tomcat 7 manager app is different from previous versions. But I was able to fix them. Now ant listtask is working fine. But others are not. For an example ant starttask returns this error.

start-webapp:

BUILD FAILED
C:\Users\rsenarath\workspace\myspringapp\build.xml:108: java.io.IOException: Server returned HTTP response code: 401 for URL: http://localhost:8080/manager/text/start?path=%2Fmyspringapp

But when I copy the url(http://localhost:8080/manager/text/start?path=%2Fmyspringapp) on the browser it asks for username password and it replies as without a problem as follows.

OK - Started application at context path /myspringapp

Can some one help me with this. My build.properties is as below

appserver.name=tomcat
appserver.home=C:/Users/rsenarath/apache-tomcat-7.0.34
appserver.lib=${appserver.home}/lib
appserver.bin=${appserver.home}/bin
deploy.path=${appserver.home}/webapps

tomcat.manager.url=http://localhost:8080/manager/text
tomcat.manager.username=tomcat
tomcat.manager.password=s3cret

and ans tasks are as below

Answer 1

In your start-webapp and stop-webapp targets you use these variables for user/pass:

tomcat.username
tomcat.password

But in your config data you set these:

tomcat.manager.username
tomcat.manager.password

The username and password are therefore probably not set when you run the start-webapp target, hence the 401. Perhaps you could update the variable names in the start and stop targets to match the config.
