[vfs] FileSystemException: Could not load VFS configuration
Hi,
I'm developing a VFS Resource Adapter and testing it out on TomEE
(1.7.1)
If I bundle the commons-vfs2 (2.1-SNAPSHOT/2.0) with the rar I get then
exception:
FileSystemException: Could not load VFS configuration from
"jar:file:/home/helge/Skrivebord/jca-parent/acme-war/target/apache-tomee/apps/acme-ra-1.0-SNAPSHOT/commons-vfs2-2.1-SNAPSHOT.jar!/org/apache/commons/vfs2/impl/providers.xml"
If I add vfs2-commons to tomee/lib and provided in my rar, then its
working OK.
Is this how it's supposed to work?
PS, the rar has dependencies to a jar having adapter/specs/dependencies
etc.

Hi,
and thanks for answering.
I figured it out.
It was a classloader issue.
so by setting classloader on STandardFilesystemMAnager I got it working.

Is this JAR and with the resource existing or not?

The default configuration mechanism resolves "providers.xml" via the
classloader of the StandardFileSystemManager class. It retrieves the
URL for that resource and loads it.
You might want to overwrite the init() method or somple create the
DefaultFileSystemManager and configure it yourself.
(I am not entirely sure why it does not work in your scenario).
