Can you share your /etc/default/tomcat8 file?

This is memory that is available to Java applications running in Java Virtual Machine (basically, a process in operating system).

It is adjusted using -X switches when starting Java. For example,

-Xms512m -Xmx4096m -XX:PermSize=512m -XX:MaxPermSize=1024m

(as recently Jason suggested to Matt)

For Tomcat, this is set via environment variable CATALINA_OPTS in bin/setenv.sh file. See http://wiki.apache.org/tomcat/FAQ/Memory#Q1.

Brian,

when talking about VM, you mean Java Virtual Machine where midPoint runs, or a virtual machine as in "hardware virtualization" (like VirtualBox etc) ?

I suppose the later. Please check how much heap has your tomcat available. It should be at least 1 GB; for any reasonable use 4 GB is recommended. See https://wiki.evolveum.com/display/midPoint/System+Requirements<https://wiki.evolveum.com/display/midPoint/System+Requirements>.

I have chmod the entire /usr/share/tomcat8/ directory to 777 and restarted tomcat8. Then it created a midpoint folder in this directory (/usr/share/tomcat8/midpoint) which it did not have before. I then also chmod this folder to 777.

The contents of this directory contains [config.xml  export  icf-connectors  idm-legacy  import  keystore.jceks  log  midpoint-activiti.h2.db  midpoint.h2.db  schema  tmp] which seems to be correct.
Whereas the contents of /var/lib/tomcat8/webapps/midpoint contains [css  fonts  img  js  less  META-INF  PageSecurityQuestions.html  status.html  WEB-INF]

But when I try to deploy midpoint I get the same msg: “FAIL - Application at context path /midpoint could not be started”

Is there another OS, tomcat, jdk combination I should try? I’m running it on a VM.

Goes on like this..

The VM currently has 2gb of ram. I will try to add more memory to the VM to see if that helps

Good idea, but according to the log, no:

Setting midpoint.home to '/usr/share/tomcat8/midpoint'.

midpoint.home = /usr/share/tomcat8/midpoint/

(so no "webapps")
BTW are you starting the Tomcat as root? MidPoint will try to create the midpoint.home directory and its content (so it must be writeable). Specifically, config.xml will be created there upon the first start.
No other thoughts yet; I may be able to install Tomcat 8 on my Ubuntu as well later.

Isn't the midpoint home folder created as 'midpoint' by default and the webapp by default is 'midpoint' ? I would think that those can collide if they are both in tomcat webapp directory?

Hi Brian,
we are deploying the midpoint.war also to webapps folder, so that certainly works.
When you changed server.xml, didn't you accidentally made some typo?

Also can you paste more from catalina.out?

Thanks,

Subject: Re: [midPoint] Deployment issues

Yes, I installed based on those instructions,

I installed JDK7 and tomcat8 on Ubuntu 16.04 using the apt-get install method. Then I used wget to download midpoint to the server and extracted it using tar. I then moved the war file into the tomcat webapps folder and changed the server.xml to change the size limitation. Tomcat creates a midpoint folder in the webapps directory since I did not change the location of the MidPoint Home Directory (midpoint.home) but it should be able to deploy in the tomcat webapps directory right?

Hi Brian,

do you install midpoint & configure it over this manual?
https://wiki.evolveum.com/display/midPoint/Installation+Guide
is configured midpoint.home directory writable for the user, who run the tomcat?

Hi

I am trying out midpoint and I cannot seem to deploy it using tomcat. I am receiving a “FAIL - Application at context path /midpoint could not be started” error message in tomcat when I try to deploy midpoint.

Can you please assist me?

I am running Ubuntu server 16.04, tomcat 8, latest midpoint release, latest java jdk
