ResourceUtils.getFile(java.net.URL, java.lang.String) throws FileNotFoundException if the URL has protocol of jar [SPR-994]

[spring-projects-issues]

Antony Sohal opened SPR-994 and commented

I think this is a bug because when this method is called, if the URL object does not have a protocol of file, it throws an FileNotFoundException. In my instance, my URL object was a location of a jar file within an EAR. After some debugging, i found that it would be better to check that the URL string start with file:// rather then check the protcol.

I came across this bug, when I was trying to add Mapping Jar Locations to a org.springframework.orm.hibernate.LocalSessionFactoryBean.
My hibernate config files are in the jar files.

public static File getFile(URL resourceUrl, String description) throws FileNotFoundException {
	if (!URL_PROTOCOL_FILE.equals(resourceUrl.getProtocol())) {
		throw new FileNotFoundException(
				description + " cannot be resolved to absolute file path " +
				"because it does not reside in the file system: " + resourceUrl);
	}
	return new File(URLDecoder.decode(resourceUrl.getFile()));
}

Indeed, resolution of a resource as java.io.File is currently just supported for URLs with "file:" protocol. I'm not aware of a way to create a java.io.File object for any other resource: if the specified resource resides within a JAR/WAR/EAR file, we can't create a file system reference for it...

Note that Hibernate's Configuration.addJar(File) method requires a java.io.File object to be passed in - that is, it expects the jar file to reside in the file system... As long as that doesn't change, I see no way to enable this for non-file URLs in Spring.

As I indicated, this would require some Hibernate Configuration method that allows for registering a jar file with something other than a java.io.File reference.

Hello,
We are facing the same issue ie FileNotFoundException but through a different use case:
Using Spring web flow and WebLogic 10, flow xml file definitions are deployed within jar files under WLS working folder.
This leads to referenced error.
