iReport.sh NullPointerException in libgcj

[kiboro]

When I try to run iReport.sh on CentOS (RedHat) 5 I get a NullPointerException. This has been mentioned before in this forum but with no answer. Full message and list of gcj libs follows:

You are using other version java (Centos). You need sun java.

 

check version

Code:

java -version

 

locate your installation

Code:

[code]find / -name java

 

Before install sun java 5 or 6 (JRE or JDK 6u3) update variables

 

(use your apropiate path)

 

Code:

[code]export JAVA_HOME=/usr/java/jdk1.5.0_13/ export PATH=$JAVA_HOME/bin:$PATH:$HOME/bin

 

and now check version

Code:

[code]java -version

 

run iReport. it's all.

Are you using Linux?

 

I had the exact same error. I had installed iReports as root and I was trying to run it as a different user. My bad, hope that helps.
