Hi, I've been following this thread with interest. I've only just started working with tomcat and servlets and I'm working on a similar rasterizing servlet.
My code so far (based on this thread) looks like :
import java.io.*; import javax.servlet.*; import javax.servlet.http.*;
import org.apache.batik.transcoder.*; import org.apache.batik.transcoder.image.*; import org.apache.batik.*;
public class BatikServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
File fin = new File("/home/aruke/servlets/400pix.svg");
File fout = new File("/home/aruke/servlets/servlet.png");
String good;
if (fin.canRead() && fout.canRead())
{
good = transcodeSVG(fin,fout);
}
else
{
good = "File Not Found";
}response.setContentType("text/html");
PrintWriter pout = response.getWriter();
String docType = "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0Transitional//EN\">";
String headStr = "<HTML><HEAD><TITLE>Testing</TITLE></HEAD><BODY BGCOLOR=\"#FDF5E6\"><b>";
String tailStr = "</b></BODY></HTML>";
pout.println(docType + headStr + good + tailStr);
}
public String transcodeSVG(File fin, File fout)
throws IOException {
String good="File Available"; try
{
FileInputStream is = new FileInputStream(fin);
FileOutputStream os = new FileOutputStream(fout);TranscoderInput in = new TranscoderInput(is);
in.setURI(fin.toURL().toString());
TranscoderOutput out = new TranscoderOutput(os);
out.setURI(fout.toString());PNGTranscoder png=new PNGTranscoder();
png.transcode(in, out);
good +="<br><br>File Transcoded";
}
catch (TranscoderException e) {
good += "Transcoder Error : " + e; } return good;
}
}
And it compiles fine. My problem is that when I try and run it under tomcat I get a
java.lang.NoClassDefFoundError: org/apache/batik/transcoder/TranscoderException
Error, and I'm stumped. All the batik stuff is in the classpath and if I modify this and run it
as a commandline app it works fine. Is there something I have to do to get batik to
work with Tomcat ?
I realise this is probably more of a tomcat question than batik, but someone might
have a quick answer ..............
Cheers Colm
