Hello,
I hava a need to view SVG on a Unix (Solaris) machine. Since there is no
SVG viewer plug-in for Netscape on a Unix machine I would like to try to use
Batik to create an applet that can be used in a browser to display SVG
content.
Can this even be done? The need is to use a web browser to view and
manipulate data in an SVG file.
I tried to do this but am having problems. Please bear with me while I try
to explain what I'm doing and maybe you could tell me what I am doing wrong.
I created the following file named svgApplet.java:
import java.awt.*;
import java.awt.event.*;
import java.net.*;
import java.io.*;
import java.applet.*;
import javax.swing.*;
import org.apache.batik.swing.JSVGCanvas;
import org.apache.batik.swing.gvt.GVTTreeRendererAdapter;
import org.apache.batik.swing.gvt.GVTTreeRendererEvent;
import org.apache.batik.swing.svg.SVGDocumentLoaderAdapter;
import org.apache.batik.swing.svg.SVGDocumentEvent;
import org.apache.batik.swing.svg.SVGTreeBuilderAdapter;
import org.apache.batik.swing.svg.SVGTreeBuilderEvent;
public class svgApplet extends JApplet {
public void init() {
JFrame frame =new JFrame("Testing");
JSVGCanvas svgCanvas = new JSVGCanvas();
File f = new File("/home/boshnyak/imageTry.svg");
try {
svgCanvas.setURI(f.toURL().toString());
} catch (IOException ex) {
ex.printStackTrace();
}
svgCanvas.setBackground(Color.lightGray);
frame.getContentPane().add(svgCanvas);
}
}
In a file named frame4.html I have the following:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Frameset//EN"
"http://www.w3.org/TR/REC-html40/frameset.dtd";>
<!--NewPage-->
<HTML>
<HEAD>
<TITLE>
frame 4
</TITLE>
</HEAD>
<BODY BGCOLOR="white">
<APPLET codebase="/home/boshnyak" code="svgApplet.class"
width=600 height=600 ></APPLET>
</CENTER>
</BODY>
</HTML>
I compile the .java as follows:
javac -classpath /home/boshnyak svgApplet.java
I get no errors. The org directory is at this level.
When I try to load the frame4.html in to the Netscape browser I get the
following:
"Applet svgApplet error:java.lang.NoClassDefFoundError:javax/swing/JApplet"
I am pretty sure this is a class path problem but I don't know what to do
about it. I've looked at the PATH environment variable to get an idea where
the java classes are. No luck.
Again my questions are:
1. Can this even be done? If so, how do I do it?
2. What am I doing wrong with the above? Maybe there is something missing.
Maybe I'm trying to be to simple about the implementation.
Any help would be greatly appreciated.
