Subreport produces error "Bad version number"

[renek]

Hello everyone,

when I use a subreport always the

Bad version number in .class file

error shows up in the frontend of JasperServer 3.5.0 (also in iReport) and I don't know why.

Can you please help me with that?

Hey renek,

 

usually this kind of error appears when you run java files with a different/older JRE than the compiler that was used.

try java -version and javac -version

[renek]

Thank you for your answer. I've just installed Java 1.6 and now it works.

[swood]

That's strange.

 

The compilation fell over trying to get the class of a parameter. Did you have a custom parameter type/class that was compiled with with JDK 1.6?

Yes, there was a scriptlet in one of the subreports. Sorry that I forget to say that.

[swood]

That's your problem then. The scriptlet jar was compiled with JDK 1.6.
