Hi,
I am trying to replicate the example of Batik in a servlet located in the
example found here:
http://www.xml.com/pub/a/2002/02/27/batik/index.html
I am struggling with this and I appreciate any help you can offer. Attached
is exactly what i have done and maybe you can help me figure out what I am
doing wrong. Any help, direction to a book I should read, or anything would
be great.
here is what I have done:
I installed IIS 5.0 web server on my local Windows 2000 machine.
I installed JRun 3.1 to act as a servlet container.
The Java Runtime for JRun is JDK1.3.1_02
I have downloaded batik1.1.1.zip and unzipped the contents of that file into
c:\batik1.1.1
I have downloaded batik-src-1.1.1 and unzipped the contents of that file
into c:\batik-src-1.1.1
I am pretty sure Jrun is working and able to run servlets because the sample
servlets that are supplied with the jrun installation are working.
I have saved Artist.java and Artmaker.java to this directory (these files
come from the website listed above)
c:\progra~1\allaire\jrun\servers\default\default-app\web-inf\classes\
My classpath is not defined at this point, and I compile Artist.java with
this command line entry (I tabbed it out for clarity)
javac -classpath
c:\Progra~1\Allaire\JRun\lib\ext\servlet.jar;
c:\Progra~1\Allaire\JRun\lib\ext\tools.jar;
c:\Progra~1\Allaire\JRun\lib\ext\parser.jar;
Artist.java
this compiles with no errors.
My classpath is still not defined at this point.
Then I compile ArtMaker.java with this command line entry (I tabbed it out
for clarity)
javac -classpath
c:\Progra~1\Allaire\JRun\lib\ext\servlet.jar;
c:\Progra~1\Allaire\JRun\lib\ext\tools.jar;
c:\Progra~1\Allaire\JRun\lib\ext\parser.jar;
c:\batik-src-1.1.1\xml-batik\sources;
c:\Progra~1\Allaire\JRun\servers\default\default-app\WEB-INF\classes
ArtMaker.java
I have to add the 4th classpath so it can make it through the Batik
Transcoder code in ArtMaker.java.
c:\batik-src-1.1.1\xml-batik\sources is the location of the Batik org
directory.
Somehow I think I am doing something wrong here.
I have to add the 5th line to the classpath because now it needs the
Artist.class (previously compiled) to compile ArtMaker.java to
ArtMaker.class.
ArtMaker.java compiles with no errors.
Okay, so now I have 2 class files (Artist.class and ArtMaker.class) in this
directory:
c:\progra~1\allaire\jrun\servers\default\default-app\web-inf\classes\
Now I have to make sure the Jrun classpath includes the needed batik jars.
I go into the JRUN admin and change the CLASSPATH Setting to:
{jrun.rootdir}/servers/lib
{jrun.server.rootdir}/lib
C:/batik1.1.1/batik-1.1.1/lib/batik-transcoder.jar
C:/batik1.1.1/batik-1.1.1/lib/crimson-parser.jar
C:/batik1.1.1/batik-1.1.1/lib/js.jar
C:/batik1.1.1/batik-1.1.1/lib/batik-svg-dom.jar
C:/batik1.1.1/batik-1.1.1/lib/batik-svggen.jar
C:/batik1.1.1/batik-1.1.1/lib/batik-awt-util.jar
C:/batik1.1.1/batik-1.1.1/lib/batik-bridge.jar
C:/batik1.1.1/batik-1.1.1/lib/batik-css.jar
C:/batik1.1.1/batik-1.1.1/lib/batik-dom.jar
I don't know if I need all these jars in the classpath or if I am missing
some. I think this is where my error is.
I restart JRUN, seems to be working, will run other servlets.
so I go to http://localhost/artmaker.html
(this comes from the above url as well)
i click on the "follow your muse" button, link and get...

I would very, very much appreciate any help you can provide. I feel like I
