Unable to start cp 6.0.1 under tomcat due to NPE in owasp csrf guard

[jon.lelong]

Hi, unable to get jaspersevrer to start due to a null pointer exception when starting up, triggered within the owasp csrf guard.

Extracts from the log:

System was installed from jasperreports-server-cp-6.0.1-linux-x64-installer.run

Tomcat is 8.0.15, jre 1.8.0_25-b17

 

Can anyone give any hints as to what is causing this, and how to fix it...

JasperReports Server 6.0.1 doesn't support JDK1.8. You'll need to use JasperReports Server 6.1.0 if you want to use JDK1.8.

On the other hand, if you want to use JasperReports Server 6.0.1, you'll need to downgrade your JDK to 1.7.

I've downloaded the latest jasper available as far as I can tell:

http://community.jaspersoft.com/project/jasperreports-server/releases

Doesn't look like 6.1 is available as a community edition according to that.

 

There are other webapps running under that tomcat instance which need java 1.8 - guess that means it won't be possible to have jasper on the same tomcat as used for everything else...

Seems like the most recent community version of JasperReports Server is 6.0.1.

Anyways, it's not a very good idea to co-exist JasperReports Server with other applications. I've found that JasperReports Server sometimes do not fully function when there are other apps on the same tomcat instance.

If you just want to display reports on a web server, it's really not too difficult to develop a simple web app.
