I have war file. I have tomcat. I copied the war package to the folder /tomcat/webapps, and run start.sh in tomcat/bin directory. In console I see that application is deploying.
org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive [xxx/tomcat/webapps/ROOT.war]
When i open http://localhost:8080 in browser i see the white page because application is still deploying(unpacking).
After console message
org.apache.catalina.startup.HostConfig.deployWAR Deployment of web application archive [/xxx/tomcat/webapps/ROOT.war] has finished in [63,582] ms
when i open http://localhost:8080 in browser i see start page.
Is there possibility to show a message in browser during application deployment(instead of white page ) without application code editing. Maybe there are some tomcat settings to handle that?
