Hello FESS team,

I find that starting FESS server takes a really long time nowadays and that’s because tomcat takes a really long time doing jar scanning. Some suggestions recommend skipping jar files in the catalina.properties file or in conf/context.xml which I couldn’t find. Could you help me guys?

Here are the last lines in server_0.log

Apr 24, 2019 5:13:27 AM org.apache.jasper.servlet.TldScanner scanJars
INFO: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.

Thanks!

There is no option at the moment.
I asked an author of the library to add a solution for this issue.

Adding this line to fess.in.sh actually works but I found that it wasn’t the reason why the took too long to start

JAVA_OPTS="$JAVA_OPTS -Dtomcat.util.scan.StandardJarScanFilter.jarsToSkip=*.jar"

It’s related to CreateSecureRandom when running inside a container but I also discovered that recreating the container solved the problem. I also mounted the /dev/urandom of the host to the container and hopefully it helps.
