ireport4 java.lang.ClassNotFoundException: org.apache.batik.svggen.SVGGraphics2DIOException

I am using Timeseries Chart. It's works fine. But, when I using it in JAVA,some exception occurs.

  JasperPrint jasperPrint = JasperFillManager.fillReport(jasperPrintFile.getPath(), paraMap, DBUtil.getConnection());

I listed all the stack trace here. Anyone who knows what's the root cause of this problem? thanks very much.

    Servlet.service() for servlet springServlet threw exception
