Spring resource classpath issue

[polosatiy]

I've just checked "getFile()" method and I've found an error.

The problem with this line:

ResourceUtils.getFile(getURI(), getDescription());

URI starts from "bundle", but ResourceUtils expects "file". That's why is doesn't work.

Try to use URL or InputStream.

So what you are saying is a bug with the spring ResourceUtils ? I guessthe value of URI getting passed is "bundle://258.0:1/repo/test.db4o".

In ResourceUtils.getFile(),

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);
		}

Here its expecting "file" but getting "bundle" and hence the exception. Thanks for debugging this for me.

But the follow-up question is how its so obvious that the protocol will be a file ? Any resource uri deployed in an OSGi bundle will always start with a bundle. Isn't this a bug ? My problem now is, the ObjectContainerFactoryBean is a third party code which I've little control over. Moreover, the inherent call to Db4o.openFile() is the only method available, so getting File is the only choice. Not sure how to resolve this now.

I think It's a bug and I've posted a bug to tracker
https://jira.springsource.org/browse/OSGI-818

If you need to use a file, I can suggest you to copy InputSteam from URL to a temp file like this:

InputStream is = resource.getURL().openStream();
File file  = File.createTempFile("tmp", "prop");
FileOutputStream os = new FileOutputStream(file);
//code to copy from is to os;

Thanks for all your help in getting this issue resolved. I followed your clue and tried couple of approaches which worked.

1. Externalizing the file and use file:///absolute_file_path

2. I extended ObjectContainerFactoryBean and instead and overriden the method to use inputstream and generate the file instead of using the getFile() from OSGiBundleResource.

But now, I've got into another issue which is has lead me to open another thread :-).

Appreciate your help....
