After upgrading Spectrum OneClick tomcat hangs on startup.
RHEL (SPECROOT/tomcat/logs - catalina.out) WINDOWS (SPECROOT/tomcat/logs - stdout.log)
WSSERVLET14: JAX-WS servlet initalizing.
WSSSERVLET12: JAX-WS context listener initializing.
Until one of the following is printed in the log, tomcat is not fully started and the OneClick UI will not available:
Starting ProtocolHandler ["http-nio-8080"]
OR
Starting ProtocolHandler ["https-jsse-nio-8443"]
Spectrum 23.3.x, 24.3.x
SPECROOT/tomcat/conf/web.xml is malformed\corrupted
1. Manually fix SPECROOT/tomcat/conf/web.xml
OR
2. locate the backup file taken during the upgrade
SPECROOT/tomcat/webapps/spectrum/WEB-INF/web.xml.bak.<date>
OR
3. Copy from another working OneClick system running the same version.
on RHEL one way to identify xml issues is trying to pass it to xmllint --format -
cat web.xml | xmllint --format -
If there are structural (not logical) errors that will usually error out which gives an indication there is a problem with the file.
