The main problem is that we do not have control on the OSGI components deployed
on our application because they are developped by our customers.
We can write a guide and explain what to do and not to do with OSGI, but we
hoped to solve the majority of problems otherwise.
What I wanted to do with:
new File("relative_path")
is to change the way relative paths are built by replacing java.io.File() with
our version of java.io.File().
Something like :
/**
* Our version of java.io.File
*/
class File {
public File(String relativePath)
{
this.path =
fs.normalize(StaticBundleAccessor.getBundle().getBundleLocation().getAbsolutePath()
+ '/' + relativePath);
this.prefixLength = fs.prefixLength(this.path);
}
}
/**
* SUN version of java.io.File
*/
class File {
public File(String pathname)
{
this.path = fs.normalize(pathname);
this.prefixLength = fs.prefixLength(this.path);
}
}
Do you think something like that is feasible ?
