error unix java execution

[gglulu]

 Hello all,

I use the ireport version 3.7.1

I built a report on windows workstation, I execute without problem.

I use a java program to create the pdf with the lib in my classpath no problem (I have Java 1.6).

I send the file GeneratePDF.java and reportporeleaseparam.jrxml on my unix server (java 1.4).

I compile the java file on a server unix, no problem but when I want to execute I have a message here below

 

 

 

Can you help me please ? 

 

 

Code:

the error isn't related to the programming logic or the report template...

it's related to the java version you use to run the code (and the related jars)

read this article:

http://techtracer.com/2007/10/10/resolving-the-unsupported-majorminor-version-490-error/

 

(the path you use in your code seems to be in windows-like format... and not in the unix-like one.)

...load("C:\\reportporeleaseparam.jrxml");...exportReportToPdfFile(jasperPrint, "C:\\reportporeleaseparamclassic.pdf");
