follow-up SOLUTION to classnotfound debug error

["Kenneth B. Harwood" <ru...@comcast.net>]

The fix is to use the Java extension mechanism (please see 
http://java.sun.com/docs/books/tutorial/ext/TOC.html). 
once i added the Batik JARs to my [Win2K] JDK ext folder:

copy \batik-1.6\lib\*.jar   \Java\jdk1.5.0_03\lib\ext

the problem was solved.  I am not exactly sure why
JApplet required use of java extensions; i was pretty
confident that a batik-aware CLASSPATH would do the 
job - a misconception that was reinforced by the java
docs!

When i run [my batik-1.6, sun jvm/jre] based JApplet this is what i get:


Exception in thread ... java.lang.NoClassDefFoundError: org/apache/batik/swing/svg/JSVGComponent
 at StartButton.run(StartButton.java:90)
 at java.lang.Thread.run(Thread.java:595)

Here is my (batik-specific) CLASSPATH:

f:\batik-1.6\lib\batik-dom.jar
f:\batik-1.6\lib\batik-svg-dom.jar
f:\batik-1.6\lib\batik-swing.jar
f:\batik-1.6\lib\batik-util.jar
f:\batik-1.6\lib\batik-awt-util.jar
f:\batik-1.6\lib\batik-bridge.jar

I realize that other Batik Jar's came with your download.  In fact, those files
are in my batik/lib directory.  But I have not put them in my CLASSPATH yet).
As i understand Java i do not need to add "ununsed" Jars/packages to my
CLASSPATH.

The <jar -tf> utility confirms that JSVGComponent is in my [batik-swing.jar]
file.
I can bring-up an JSVGCanvas in an application (JFrame).  It's when I try to
use the Class within a JApplet that I get grief.


--------------------------------------------------------------------------------

   Well it would be useful to know what class was not
found in the ClassDefNotFound error (copy the stack trace).

   The problem is almost certainly an issue with your
classpath (which you also haven't included).  But I don't
really have enough information to provide a solid answer.
