19: int width=60, height=20;
20: BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
21: Graphics g = image.getGraphics();

note The full stack trace of the root cause is available in the Apache Tomcat/6.0.18 logs.

 

 

解决方法:

修改 tomcat/bin/catalina.sh 文件,添加 一行    JAVA_OPTS=-Djava.awt.headless=true 

重启tomcat后,问题解决。
