Problem in starting of iReport

[sa_38]

Hello,

 

I have a problem when I start iReport from linux with iReport.sh. I have the following message :

 

sa@europe:~/iReport-2.0.4/iReport-2.0.4$ ./iReport.sh

On windows all work very well. But I must use Linux.

Sorry for my english.

 

Thank you for your help

@ evocati

Check your Classpaths.

Seems like the iReport.jar is missing

@ sa_38

Maybe the problem is your Java-Compiler.

Try to use the Compiler provided by Sun instead of the GNU-Version.

I was able to get it working by selecting the proper java version with this in ubuntu, it will probably work in debian too.

update-java-alternatives -l

sudo update-java-alternatives -s java-1.5.0-sun

The last part should be from what you want in the previous command. I selected the sun java version and then it worked for me.

YEs, this is the right solution, iReport (any version) requires a Sun JDK, which is the only one that currently implements some required AWT classes.
