Birt Viewer export PDF in server Debian

Migrateduser

Hi all,

I have a problem with the value of bar chart when I make a export pdf in the birt viewer in my prod server, while in dev server it is displayed correctly.

In my server dev I have a Ubuntu :

Viewer Version : 4.2.1

Engine Version: 4.2.1

JRE version: 1.7.0_17

In server prod a Debian :

Viewer Version : 4.2.1

Engine Version: 4.2.1

JRE version: 1.6.0_18

I think it comes from the Java version, but in Debian by default and the stable version of java is 6.

how can I solve this problem ?

Thank you in advance.
