JasperReport Server 9.0.0 - Internal server error org.apache.jasper.JasperException: java.lang.NullPointerException

[kp402]

Hello,

I am complete new with Jasper Reports.

I installed the     JasperReports-Server_9.0.0_win_x86_64.exe   on my blank windows system (no other databese/java/jboss/tomcat/what else preinstalled)

and I also got this problem at post-install step : cannot run program "git" ...  I found several entries in this forum but no solution

Anyway - I got then tomcat server up and running. And in the tomcat manager I can start /jasperserver-pro  --> state = true

But with http://localhost:8080/jasperserver-pro/login.html  there is always this Internal Server Error.

Logfile jasperreportstomcat-stdout shows:     ERROR SystemErrorController,http-nio-8080-exec-1:115 - Internal server error org.apache.jasper.JasperException: java.lang.NullPointerException

Has anybody an idea what I can do?

thanks in advance

ok, I found solution by myself

it seems, that JasperReports-Server install exe is not so much well compiled for windows platforms.

First I had to install GIT (Git-2.44.0-64-bit.exe) and JAVA (jre-8u401-windows-x64.exe) seperately. And check the JAVA home path 

   echo %JAVA_HOME%
   C:\Program Files\Java\jre-1.8

After that I can install JasperReports-Server but during last phase I had to copy the file "keystore.init.properties" manually from .\buildomatic\build_conf\default   to   .\buildomatic\conf_source\templates\webapp\WEB-INF\classes   (which was already mentioned in post Missing keystore-configuration.xml - Products - Jaspersoft Community)
