问题
I have been searching here for a while, than i decided to write a question, since I am not able to find anything helpful.
I just get assigned to pentaho in my company, so I still consider myself as novice when its about Pentaho.
So, here is my question: I was doing some changes in one report already working. It has to show some data from DB and also pictures. And that was the problem, report was not showing pictures. But it was showing data and after click for picture, error.
So i added symlink from tomcat/webapps/ to /var/dav/davserver where those screens are (as adviced man who was working on it before me). But it did that, whole report freezed after pushing "view report" since davserver directory has some hundretthousand pictures.
In order to not kill server, we decided to remove it from there, since we need to redesign whole screens saving.
But, when I delete that column from my report, it freezes anyway.
and my question is: Is there any web report log, where I can see all errors and operations that pentaho run when generating report? I want to see, why is it freezing after pushing "View report".
Many thanks, RastoR

There are two log files generated in Pentaho depending on your log4j properties.
One file can be viewed from the following location also told earlier:
\biserver-ce\tomcat\logs\catalina.out
And the second file can be accessed from the following path in your bi-server:
\biserver-ce\tomcat\bin\pentaho.log
Make sure that for adding pictures in your report, the Static Image Box is used and the path to the picture file is defined correctly in the path. These pictures have to be present inside the bi-server similarly how you place your .xml and .xaction files. One good way of doing that is making a separate folder inside this directory for all your pictures and picking it from there:
\biserver-ce\pentaho-solutions

As you're talking about server side things here all you need to know is that Pentaho is nothing more than a standard tomcat webapp. So go to the tomcat logs directory and look at catalina.out
does it work when you run the report in the report designer tool? Does sound odd to be "freezing" like that, may be worth checking what network requests it is doing and seeing if they resolve ok etc.
