Hi,
We have a web application deployed on Tomcat server and is working pretty f=
ine, except in one mode. The web application is available through 2 modes o=
f links - one is regular without load balacer and other is Single Sign On b=
ased through load balancer. The normal mode works fine with one start after=
new war deployment. However SSO link through load balancer does not work f=
ine. When stooped and started again, it works just fine.
Here is the sample directory structure:
Tomcat
webapps
MyApp
WEB-INF
web.xml
jsp
=
myapp.jsp
MyApp.war
bin
logs
conf
web.xml
Deployment Procedure:
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
Issue:
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 d=
irectory showing the MyApp.war and MyApp directory link.
Now all we need to workaround this is just stop the server again and then s=
tart 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
<servlet>
<servlet-name>default</servlet-name>
<init-param>
<param-name>listings</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
Please note the web.xml in Tomcat/webapps/MyApp/WEB-INF directory has below
<welcome-file-list>
<welcome-file>myapp.jsp</welcome-file>
</welcome-file-list>
The application has only myapp.jsp and none of index.* files
myapp.jsp is as below
<html><head><META URL=3D<%=3Drequest.getContextPath()%>/who.do"></head><bod=
y/></html>
Somehow first time when new war is deployed, old exploded directory is dele=
ted 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. No exceptions in log file.
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 dire=
ctory and rest of steps same. But it does not help either. If we drop the n=
ew war while the server is running, it does not take the changes in new war=
.
