Batik Rasterizer with Linux red hat

["M. ALIPRENDI" <al...@athamante.com>]

Hello,

    I've big problem to run batik rasterizer (I only need to convert a svg file to jpg) on a linux redhat 6.3 server (without X environment it's a web server). It works fine on my pc but when I try it on a linux server l've the following message :
  Exception in thread "main" java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

On your mailing list archives, I found this solution : 

Just use the Pure Java AWT available at http://www.eteks.com/pja/en/ as
replacement for the awt toolkit. The PJA doesn't use any native graphics
resource of the system. Switching the toolkit from X11 or windows default
toolkit to PJA toolkit is simple: change the "awt.toolkit" system property
to "com.eteks.awt.PJAToolkit".

Let's go!  I've downloaded, deployed, modify batik src : 
        System.setProperty ("awt.toolkit", "com.eteks.awt.PJAToolkit");
        System.setProperty ("java.awt.graphicsenv","com.eteks.java2d.PJAGraphicsEnvironment");
        System.setProperty ("java.awt.fonts","/usr/share/fonts/default/Type1/:/usr/share/fonts/default/ghostscript/");

=> (the object PJAGraphicsEnvironment can be found, I've tried, just upper the method that launch the exception, to instantiate a variable and that's work.
  Exception in thread "main" java.lang.Error: Could not find class: com.eteks.java2d.PJAGraphicsEnvironment

Configuration : 

    Batik 1.1.1 (Batic 1.5 beta2 also tried : same problem)
    RedHat 6.3
    JVM : IBMJava2-13 and jdk-1.3.1_03 (don't work with both)

So, could you tell me if I need to deploy Xwindow on the server knowing that there is no screen connected, or if I must try to found an other way to convert my svg file...

Thanks,
Cordialement,
