The following:

public static File jarFile(Class clazz) throws IOException {
URL res = jarURL(clazz);
String resURL = res.toExternalForm();
String originalURL = resURL;
if(resURL.startsWith("jar:"))
return fromJarUrlToFile(resURL);
if(resURL.startsWith("wsjar:"))
return fromJarUrlToFile(resURL);

if(resURL.startsWith("code-source:/"))

{ // OC4J apparently uses this. See http://www.nabble.com/Hudson-on-OC4J-tt16702113.html resURL = resURL.substring("code-source:/".length(), resURL.lastIndexOf('!')); // cut off jar: and the file name portion return new File(decode(new URL("file:/"+resURL).getPath())); }

if(resURL.startsWith("file:")) {
// unpackaged classes
int n = clazz.getName().split("
.").length; // how many slashes do
wo need to cut?
for( ; n>0; n-- )

{ int idx = Math.max(resURL.lastIndexOf('/'), resURL.lastIndexOf('\\')); if(idx<0) throw new IllegalArgumentException(originalURL + " - " + resURL); resURL = resURL.substring(0,idx); }

// won't work if res URL contains ' '
// return new File(new URI(null,new URL(res).toExternalForm(),null));
// won't work if res URL contains '%20'
// return new File(new URL(res).toURI());

return new File(decode(new URL(resURL).getPath()));
}

throw new IllegalArgumentException(originalURL + " - " + resURL);
}

...makes assumptions about the presence of protocols used. JBossAS (and other
projects based upon JBoss Microcontainer Virtual File System) employs a file
abstraction layer, leading to errors such as:

java.lang.IllegalArgumentException:

I've set this issue to "www" subcomponent in absence of "remoting" or "main",
please adjust as necessary.
