New Revision: 958615
URL: http://svn.apache.org/viewvc?rev=958615&view=rev
Log:
Implement support for using *.jar pattern in VirtualWebappLoader to specify all
JAR files in a certain directory.
This is inspired by Bootstrap.createClassLoader(..) and
ClassLoaderFactory.createClassLoader(..).
There is a small difference with regards to
ClassLoaderFactory.createClassLoader(..) implementation:
1. I removed the file.canRead() checks as I think that they are not necessary
here. I am checking existence and type only.
2. Note that isFile()/isDirectory() are documented to return false if the path
does not exist, so using a separate exists() call there is not necessary.
Also three other changes:
1. Added trim() to the tokens.
2. Implemented debug logging.
3. Removed "not for production" warning from the JavaDoc.
An update for the documentation (/config/loader.html) should follow later.
