I'm having a problem with TC4.0.3 (Win2K, JDK1.3.1)
I have some code that reads a property file and tries to load fonts
listed within. ClassLoader.getResource() is used to locate the prop file
and font files
I'm attaching the servlet test code. This code works fine under TC3.2.2
and TC3.3a
BTW, the files being loaded are in a jar in my WEB-INF/lib directory.
I've seen two problems:
1. when the font path contains a space, the resource URL is OK, but
calling url.openStream() returns null. (works fine in TC3.x)
2. even if the input stream is good (as shown in the log below), there
seems to be a problem creating a temp file.
Could problem 2 be caused by some security features that have been put
in place sincee TC3?
Here is my catalina.out (the relavent section)
file = fonts/Pgl_____.ttf
resource =
jar:file:D:/work/pix.light/light/WEB-INF/lib/fonts.jar!/fonts/Pgl_____.ttf
input stream = java.util.zip.ZipFile$1@5dd910
java.io.IOException: The system cannot find the path specified
