Hi
I saw Jason Lane's message of 7-Apr on the this mailing list. I'm
getting the same problem. I looked for but didn't spot any reply to
Jason's message. Does anyone have a solution to this problem?
Details of my experience follow...
Windows XP 5.1 (build 2600 service pack 2)
Java 1.5.0_01
Ant 1.6.5
I built Batik from the latest sources (batik-src-06-04-29.zip) and then
built the RasterizerTask. Then defined the task in the Ant build.xml. I
get the following error (using "ant -debug") on the build.xml line which
runs the rasterizer task:
BUILD FAILED
