Hi Muhammad Hassan,

Have you added the library path to the environment variables?

For example: Djava.library.path=/usr/share/tomcat8/8.0.38/webapps/Thingworx/WEB-INF/extensions

[mhassan1]

I have only added JAVA_HOME, I am not sure which library paths I need to add since I am only following the thingworx guide

[ytella]

I would like to know the OS on which you are trying to install ThingWorx? Is it RHEL or Ubuntu?

[mhassan1]

I am installing on RHEL7

[ytella]

Could you also please share the below details:

• Are you starting tomcat manually or is it through a service file?
• If you are starting tomcat manually with start.sh script, have you created setenv.sh file?
• If you are starting tomcat with tomcat.service file, make sure you have all the below paths pointing to the right directories:

[mhassan1]

I tried running tomcat as a service but it was not working. Therefore, I am starting it manually for now. I will now create a setenv.sh file and try. Tomcat was working fine but then when I installed Thingworx 7.4 it no longer runs. But when I remove Thingworx.war file, tomcat starts normally again.

[ytella · Accepted solution]

Could you please add the below contents to the setenv.sh file,restart tomcat and launch the composer:

# Java Options

export JAVA_OPTS="-Djava.awt.headless=true - Djava.net.preferIPv4Stack=true -Dserver -Dd64 - XX:+UseNUMA -XX:+UseConcMarkSweepGC -Dfile.encoding=UTF-8 -Djava.library.path=/usr/share/tomcat8/8.0.38/webapps/Thingworx/WEB-INF/extensions "

export JRE_HOME=/usr/lib/jvm/jdk1.8.0_x/jre

[mhassan1]

It worked ! Thanks it seems this was the only issue

[ytella]

Glad to know that it worked!

hello

I have exactly the same problem (Ubuntu 14 with Postgres) 

tomcat8.service env :

			Environment=CATALINA_PID=/var/run/tomcat.pid
			Environment=JAVA_HOME=/usr/lib/jvm/jdk1.8.0_92
			Environment=CATALINA_HOME=/usr/share/tomcat8/8.0.33
			Environment=CATALINA_BASE=/usr/share/tomcat8/8.0.33
			Environment=CATALINA_OPTS=

catalina.out :

Attempting to load validation.properties via file I/O.

Expecting an absolute path of the library: libFlxCore64.so.2016.08

I created the setenv.sh :

# Java Options

export JAVA_OPTS="-Djava.awt.headless=true -Djava.net.preferIPv4Stack=true -Dserver -Dd64 -XX:+UseNUMA -XX:+UseConcMarkSweepGC -Dfile.encoding=UTF-8 -Djava.library.path=/usr/share/tomcat8/8.0.38/webapps/Thingworx/WEB-INF/extensions "

export JRE_HOME=/usr/lib/jvm/jdk1.8.0_92/jre

but it doesn't solve the issue for me

any other idea ?

Thanks

[pjoly]

I found my mistake

8.0.38 -> 8.0.33 for tomcat in setenv.sh in my case

Now it's OK after many hours  of battle to get  Thingworx  working on ubuntu + Postgres

Hope to see a simpler installation process one day  (a virtual marchine ready to download and use ?)  ;-)

There don't appear to be any errors in that log that are interesting other than the reference to the shared library libFlxCore... That could be causing it to crash, but it doesn't look to me like it is. A second place to check is ThingworxStorage/logs/ApplicationLog.log. I have occasionally seen nothing of interest in the tomcat logs but will find an error in ApplicationLog.log that indicates the Thingworx webapp has terminated (licensing issues being the primary problem)
