Newbie: Problems with SVG

[=?ISO-8859-1?Q?Michael_Br=E4uer?=]

Hi,

I'm a Newbie in using FOP. I wrote some simple XSL-FO Files and created
some nice PDFs. Now I want to embed a SVG in the XSL-FO file.
My XSL-FO:
<fo:instream-foreign-object>
<svg width="150" height="150" xmlns="http://www.w3.org/2000/svg">
<polygon points="10,10 50,50 100,10" stroke="red"
stroke-width="2"/>
</svg>
</fo:instream-foreign-object>

FOP stops with the following message:
Exception in thread "main" java.lang.NoSuchMethodError:

With other graphics like gif or jpeg it worked well. So I think the
problem is the SVG.

My System: WINNT 4.0 (SP6), FOP0.20.5, JDK1.4

I think the Classpath in the fop.bat is correct:
@echo OFF

rem %~dp0 is the expanded pathname of the current script under NT
set LOCAL_FOP_HOME=
if "%OS%"=="Windows_NT" set LOCAL_FOP_HOME=%~dp0

set LIBDIR=%LOCAL_FOP_HOME%lib
set LOCALCLASSPATH=%LOCAL_FOP_HOME%build\fop.jar
set LOCALCLASSPATH=%LOCALCLASSPATH%;%LIBDIR%\xml-apis.jar
set LOCALCLASSPATH=%LOCALCLASSPATH%;%LIBDIR%\xercesImpl-2.2.1.jar
set LOCALCLASSPATH=%LOCALCLASSPATH%;%LIBDIR%\xalan-2.4.1.jar
set LOCALCLASSPATH=%LOCALCLASSPATH%;%LIBDIR%\batik.jar
set
LOCALCLASSPATH=%LOCALCLASSPATH%;%LIBDIR%\avalon-framework-cvs-20020806.jar
set LOCALCLASSPATH=%LOCALCLASSPATH%;%LIBDIR%\jimi-1.0.jar
set LOCALCLASSPATH=%LOCALCLASSPATH%;%LIBDIR%\jai_core.jar
set LOCALCLASSPATH=%LOCALCLASSPATH%;%LIBDIR%\jai_codec.jar
java -cp "%LOCALCLASSPATH%" org.apache.fop.apps.Fop %1 %2 %3 %4 %5 %6
%7 %8

I tried to install an other version of batik, or the JRE, but it didn't
work.

I hope someone has an idea, I'm a Newbie with Java, too, so it's very
hard for me to follow the discussion on this board.

Hopefully
