Tomcat Web App - Strange issue. Requires 2 restart for SSO mode to work
posted 5 years ago
I have a small web application deployed on Tomcat server and is is working pretty fine, except in one mode. The web application is available through 2 modes of links - one is regular and other is Single Sign On based.
Here is the sample directory structure:
Stop the server
Copy the new war to webapps replacing the old one
remove the complete diretcory of MyApp recursively (rm -rf MyApp)
start the server
We try both the links of application. The normal one works just fine first time itself. The SSO link shows up the directory listings page of webapps directory showing the MyApp.war and MyApp directory link.
Now all we need to workaround this is just stop the server again and then start it. Surprisingly both SSO mode link and normal works totally fine.
This is recurring problem. Is there a proper permanent fix to this?
Please note the web.xml in Tomcat/conf directory has below
Please note the web.xml in Tomcat/webapps/MyApp/WEB-INF directory has below
The application has only myapp.jsp and none of index.* files
myapp.jsp is as below
Somehow first time when new war is deployed, old exploded diretcory is deleted and server is started, the Tomcat might not be finding xcard.jsp or the application specific web.xml and hence it is listings the directory based on settings in Tomcat/conf/web.xml
Second time however it finds the web.xml and xcard.jsp and hence works.
We even tried changing deployment procedure not to delete the exploded directory and rest of steps same. But it does not help either. If we drop the new war while the server is running, it does not take the changes in new war.
