Thanks for the answer of my last query ID: 3056438. Yes, you are right. The problem is caused by default java version on linux which is IcedTea6. I reinstalled the JDK1.5 and it works now.
But now i have other problems, it can't generate barcode if i set output to svg or eps. I am using jdk1.5.0_11 and barcode4j-2.0
I get the following exception:
588953 [RMI TCP Connection(20)-192.168.9.7] INFO barcodeProcess.BarcodeGenerator - BufferedImage:null
588953 [RMI TCP Connection(20)-192.168.9.7] INFO com.mhgroup.backend.barcodeProcess.BarcodeGenerator - BufferedImage:null
java.lang.IllegalArgumentException: im == null!
Could you give me some advise?
