Colleagues,

please follow the installation instructions, if you want to install Calc 1.
It requires the instructions to be read.

We're working on Calc2 that will definitely fix all the installation issues.

Regards,
Mino

Dear,

from the log, it looks like you have stopped Calc.

Please make sure it's running and also, could you please try with a different browser?

Thank you,

Mino

Dear,
There's no such thing for an application server as 'stopping automatically'.

I also see from the last screenshot, that the page is not blank.

Are you sure the installation procedure went successfully (Path, passwords, etc...)?

Thank you,

Mino

Thanks for the answers which you provide Mino, 
after looking this post
[http://www.openforis.org/support/questions/378/non-response-of-calc/398][1] I realize the problem,

the problem was the R version, which was 3.2.0 , by installing a version 3.1.0 and required package the web is loaded and is working now. 

Thanks.

Thanks all, indeed i realized after all also that it was the same or at least very similar problem as paul had (non-response-of-calc: tomcat did NOT START/STOPPED 'automatically', the web-browser opened but stayed EMPTY. In my case i fear that Postgres created or developed a problem, affecting also other installed software.
Fix: Restart from scratch with latest versions of JDK and Postgres but indeed R version 3.1.0 (not later)!
