Jonathan, I checked in some code for you. The solution is just to use
absolute paths, not relative ones. This works for me both in Eclipse and
from the Jar file.
Bytes[] data =
getResourceAsBytes("org/openscience/jmol/app/images/angleButton.gif")
private static byte[] getResourceAsBytes(String fullPath) {
byte[] buf = new byte[1024];
byte[] bytes = new byte[4096];
BufferedInputStream bis = new BufferedInputStream(ClassLoader
.getSystemResourceAsStream(fullPath));
int len = 0;
int totalLen = 0;
try {
while ((len = bis.read(buf)) > 0) {
totalLen += len;
if (totalLen >= bytes.length)
bytes = ArrayUtil.ensureLength(bytes, totalLen * 2);
System.arraycopy(buf, 0, bytes, totalLen - len, len);
}
buf = new byte[totalLen];
System.arraycopy(bytes, 0, buf, 0, totalLen);
} catch (Exception IOException) {
Logger.error("WebPanel IO ERROR reading resource " + fullPath);
return null;
}
return buf;
}
