[resolved]scriptlet with Netbeans and ireport 4.5.1 - major.minus version error

[thegg]

Hi,

I have ireport 4.5.1

I have there java version :

java version "1.7.0_04"
Java SE Runtime Environment (build 1.7.0_04-b22)
Java HotSpot 64-Bit Server VM (build 23.0-b21, mixed mode)

Working on 7x64bit os

I need to use a scriptlet for my reports, so I installed just now the netbeans IDE 7.2.1

I follow all the explanation on the ultimate guide to generate and add the scriptlet on the report.

When I want to preview my report I have this error log :

I found the "Unsupported major.minor version 51.0" problem in any forums but I don't see how to solve the problem here (install the 4.8 ireport designer ?)

I wait for any advice,

Thx,

Hum ok, after checking my OS :

I found a java 1.6 32bit on my workstation (ireport run with it)

I managed to add this version on my netbean IDE and after build, all run perfect.

(I tested ireport 4.8 but after experienced uuid error, I removed it... sorry)
